Run Your Small Business Like a CFO—Even If You Can't Afford One

Imagine two small businesses, each generating $1.5 million in annual revenue.

The first is growing rapidly. Its owner works long hours, customers seem happy, and sales are increasing. Yet cash is constantly tight. Customers take too long to pay, expenses keep creeping upward, and the owner is never quite sure how much money can safely be taken out of the business. Every unexpected expense feels like a crisis.

The second business is growing more slowly. But its owner understands where profits come from, knows which customers and services make money, maintains adequate cash reserves, and can anticipate financial problems months before they become emergencies. Decisions about pricing, hiring, equipment, and expansion are made with a clear understanding of their financial consequences.

Which business would you rather own? And which would a potential buyer, investor, or lender find more attractive?

The answer illustrates an important distinction: Running a successful business is not just about generating revenue. It's about converting revenue into sustainable profits, converting profits into cash, and building an enterprise whose success does not depend entirely on the owner.

Large companies employ chief financial officers (CFOs) to manage these challenges. Most small businesses cannot justify a full-time CFO, whose compensation may exceed what the business can reasonably afford. But small business owners can adopt many of the same financial disciplines without hiring one. 

The goal isn't to become an accountant or master complicated financial terminology. It's to understand the economic engine of your business well enough to make better decisions, avoid preventable problems, and steadily increase the value of what you're building.

First, understand the three financial statements

Many business owners receive financial statements from their bookkeeper or accountant but rarely examine them beyond checking whether the business made a profit. A CFO looks at three fundamental reports together, because each answers a different question.

The Income Statement: Are We Actually Making Money?

The income statement, also called the profit and loss statement or P&L, summarizes revenue, expenses, and profit over a period, usually a month, quarter, or year.

Consider a business with the following monthly results:

In this example, the business earns a 40% gross profit margin and a 10% operating profit margin, before interest and taxes. Those two percentages reveal different things.

The gross profit margin tells you how much revenue remains after paying the direct costs of providing your product or service. Those costs might include materials, merchandise purchased for resale, production labor, or subcontractors.

The operating profit margin tells you how much remains after covering other business expenses such as administrative salaries, rent, advertising, software, insurance, and utilities.

Why does the distinction matter?

Suppose the company increases sales but its gross margin falls from 45% to 40% because supplier costs rise, employees require more hours to complete jobs, or management offers excessive discounts. At $100,000 in monthly revenue, that five-percentage-point decline represents $5,000 in lost gross profit every month, or $60,000 annually, assuming the same sales volume.

A business owner focused primarily on growing sales might overlook the deterioration. A financially disciplined owner will investigate whether prices need to increase, purchasing costs can be reduced, operations have become less efficient, or the sales mix has changed.

This is how the income statement becomes a management tool rather than merely a historical accounting report.

It's also important to distinguish real business profitability from profits that exist partly because the owner is underpaying themselves. If you work 60 hours a week but take little or no salary, reported profits may look impressive even though replacing your work with a paid manager would substantially reduce them.

That distinction matters both for managing the business and, eventually, determining its value.

The Balance Sheet: What Do We Own, and What Do We Owe?

The balance sheet shows the financial position of the business at a particular moment. It includes assets such as cash, customer receivables (invoices awaiting payment), inventory, and equipment. It also includes liabilities such as supplier bills, loans, and taxes owed. The difference between assets and liabilities is the company's equity—its accounting net worth.

But the balance sheet reveals something more useful than net worth alone: where the company's money is tied up and what financial obligations it faces.

For example, a business may report substantial assets but have very little usable cash because most of those assets consist of slow-moving inventory and unpaid customer invoices. Another company may appear profitable but carry so much debt that its scheduled repayments leave very little room for error.

A CFO pays particular attention to working capital: the short-term resources needed to operate the business, especially receivables, inventory, and supplier payables. The practical question is whether the company's normal operating cycle creates cash or constantly consumes more of it.

The Cash Flow Statement: Where Did the Money Go?

This is often the most revealing—and most misunderstood—financial statement for a small business owner.

Consider our company reporting $10,000 in monthly operating profit. Now suppose that, during the same month:

• Customer receivables increased by $35,000 because customers hadn't paid their invoices.
• Inventory increased by $12,000 because the company stocked up for future sales.
• The company repaid $5,000 of loan principal.

Assuming other balances remained unchanged and ignoring taxes and noncash accounting adjustments, the approximate change in cash would be:

What if both spouses are high earners?

Consider a couple receiving $3,600 and $2,900 per month. While both are alive, their combined Social Security income is $6,500 monthly. When one dies, the survivor does not continue receiving $6,500. Generally, the smaller of the two benefits disappears, and the survivor receives the higher applicable amount. Suddenly the household has only $3,600 of Social Security income, although household expenses may decline far less than proportionately. The survivor may still have substantial mortgage costs, property taxes, insurance, maintenance, or lifestyle expenses. Meanwhile, the household may move from married tax brackets to generally less favorable single brackets.

This is a common financial surprise after the death of a spouse. The fact that both partners have substantial assets doesn't eliminate the value of increasing the larger benefit. It may also change which person should delay. In couples with similar earnings, the age difference and the likely length of the survivor period can become more important than simply labeling one spouse the "higher earner."

Large age differences can change everything

A 70-year-old married to a 68-year-old has a different Social Security planning problem from a 70-year-old married to a 53-year-old. When the age difference is substantial, the younger spouse may be collecting a survivor benefit many years after the older partner dies. That makes the older, higher earner's claiming decision particularly consequential.

For example, imagine a wealthy retired executive who is 68 and has a 52-year-old spouse. The executive has a sizable retirement benefit. The younger spouse worked intermittently and will qualify for a much smaller benefit. Claiming at 68 provides immediate income to the household. Waiting until 70 increases the executive's future benefit—and potentially the spouse's eventual survivor benefit—for a retirement period that could extend decades into the future. That future survivor benefit is an asset in everything but its legal form: it cannot be sold or passed through a will, but it may provide substantial ongoing financial protection.

The younger spouse generally cannot begin ordinary survivor benefits until age 60, unless disability or eligible child-care provisions apply. Claiming survivor benefits before the survivor's full retirement age can reduce them. Consequently, a large age difference calls for more than simply choosing the larger check. The couple should examine when the older spouse might die, when survivor benefits would become available, the younger spouse's other income, and how the estate would finance any gap.

Windows and widowers have options most married couples don't

The death of a spouse creates both emotional and financial disruption. Unfortunately, many surviving spouses make Social Security decisions without realizing that survivor benefits follow different rules from ordinary retirement benefits. A surviving spouse can generally begin receiving survivor benefits at age 60, or as early as 50 in certain disability situations. Benefits may also be available at younger ages when caring for an eligible child.

But claiming early usually reduces the survivor payment. A full survivor benefit can be available at the survivor's applicable full retirement age, which may differ from their retirement-benefit full retirement age. Importantly, delaying survivor benefits beyond survivor full retirement age does not produce additional delayed retirement credits.

There is another possibility that can be particularly valuable. Suppose a widow is 62. She is eligible for a survivor benefit based on her late husband's work history, but she also earned a substantial retirement benefit on her own record. Her own benefit could continue increasing if she delays claiming it until 70. Depending on the amounts involved, she might collect survivor benefits first, then switch to her own larger retirement benefit at 70.

Alternatively, if the deceased spouse's survivor benefit would ultimately be higher, she might collect her own retirement benefit earlier and later switch to the larger survivor payment. Unlike ordinary retirement and spousal benefit combinations, these survivor situations can permit genuine sequencing strategies.

The correct choice depends on each benefit's amount and applicable claiming age, whether the survivor is still working, and whether benefit reductions apply. The Social Security Administration specifically recognizes these switching options.

A newly widowed person should evaluate them before filing. Survivor applications generally require contacting Social Security rather than simply completing the ordinary online retirement application.

Windows and widowers have options most married couples don't

Divorce ends a marriage. It doesn't necessarily eliminate Social Security rights arising from that marriage. If you were married to someone for at least 10 years, you may qualify for divorced-spouse benefits based on that former spouse's earnings record.

For ordinary divorced-spouse retirement benefits, you generally must be at least 62, unmarried, and eligible for a benefit greater than what you receive solely on your own record. At your full retirement age, the maximum divorced-spouse benefit is generally 50% of your former spouse's full-retirement-age benefit. Claiming earlier can reduce it.

Your former spouse does not need to give permission. Your claim does not reduce their own benefit, and the fact that they have remarried does not by itself prevent your entitlement. 

If your ex-spouse has not claimed benefits, you may still be able to collect on their record provided the divorce has been final for at least two years and both of you meet the applicable age and eligibility requirements. That two-year condition is generally unnecessary if your ex is already receiving qualifying benefits.

A surprisingly important divorce anniversary

Imagine a couple who divorce after nine years and 11 months of marriage. The lower-earning spouse may lose eligibility for divorced-spouse benefits that could have been available had the marriage lasted at least 10 years. 

For someone who stepped away from a career to raise children, that difference can be financially meaningful. It does not mean anyone should remain in a harmful marriage for Social Security purposes. But when divorce timing is already under discussion, approaching the 10-year threshold deserves attention alongside retirement accounts, real estate, and other marital assets.

What happens when an ex-spouse dies?

A surviving divorced spouse who was married for at least 10 years may qualify for survivor benefits based on the deceased former spouse's earnings record. Those benefits can potentially be larger than ordinary divorced-spouse retirement benefits.

Remarriage rules are particularly important. Generally, remarriage prevents collection of ordinary divorced-spouse benefits on a living former spouse's record while the new marriage remains in effect, subject to certain exceptions. But remarriage at age 60 or later generally does not prevent entitlement to survivor benefits from a deceased former spouse.

Certain disability-related exceptions also exist. That means the age at which a widow, widower, or surviving divorced spouse remarries can have real financial consequences.

In blended families and second marriages, Social Security planning should be part of the broader financial discussion before remarriage—not an afterthought.

Unmarried couples: Your estate plan cannot replace Social Security's marriage rules

Here's a situation that catches sophisticated households off guard.

Imagine two financially successful people who have lived together for 25 years. They own a house together, have carefully drafted wills and trusts, and have named each other as beneficiaries of investment and retirement accounts. They have never married. One partner dies.

The survivor may inherit millions of dollars under the estate plan, yet have no automatic right to Social Security survivor benefits based on the deceased partner's record. Social Security generally ties spousal and survivor entitlements to a legally recognized marital relationship. Some common-law marriages, civil unions, domestic partnerships, and other legally recognized non-marital relationships may qualify under applicable rules. But simply living together for decades does not guarantee eligibility.

The Social Security Administration acknowledges that some non-marital legal relationships qualify; the outcome depends on the specific legal relationship and applicable law. 

For affluent unmarried couples, this is a strong reason to integrate Social Security into estate and relationship planning. A trust can transfer assets. A life insurance policy can pay the surviving partner. Beneficiary designations can govern investment accounts. None of those arrangements automatically creates the federal survivor benefit associated with a qualifying marriage.

Conversely, marrying can affect taxes, inheritance rights, support obligations, and other financial matters. The Social Security benefit alone should not dictate the decision.

For couples considering marriage later in life, timing also matters. Ordinary spousal benefits generally require at least one year of marriage, and survivor benefits generally require at least nine months, although exceptions exist.

These are issues worth reviewing before a late-life marriage, especially when the partners have a substantial age gap.

One overlooked exception: Older parents with young children

Not every claiming decision is about the retiree and spouse.

Consider a 67-year-old business owner with a 14-year-old child from a second marriage. The parent may reasonably plan to wait until 70 to maximize retirement benefits. But if the parent begins receiving Social Security, the child may also become eligible for dependent benefits on that parent's earnings record. Eligible children can generally receive benefits until age 18, sometimes longer if they remain qualifying students or have a qualifying disability. A spouse caring for an eligible young child may also be entitled to benefits even if the spouse is younger than 62. 

These family benefits can change the arithmetic substantially, although Social Security's family maximum and earnings-test rules may limit actual payments. If the older parent waits until 70, some years of potential dependent-child benefits may disappear permanently.

This is an example where a household-level analysis may support earlier claiming even for a wealthy person with excellent health. Families supporting an adult child whose disability began before age 22 should also investigate the special benefit rules that may apply.

Social media claim #3: "There is no tax on Social Security anymore"

This is another claim that requires careful interpretation. Under current federal law, Social Security benefits can still be taxable. Depending on your other income, up to 85% of your Social Security benefits can be included in federal taxable income. That does not mean an 85% tax rate. It means up to 85 cents of each dollar of benefits may be counted as taxable income and taxed at the applicable income-tax rates.

For affluent retirees with substantial pensions, taxable investments, IRA distributions, or other income, the maximum inclusion is  common. Legislation enacted in 2025 introduced an additional deduction for people age 65 or older for tax years 2025 through 2028. The deduction can be up to $6,000 per eligible person, or $12,000 for married couples when both spouses qualify. It phases out when modified adjusted gross income exceeds $75,000 for individual filers or $150,000 for joint filers.

As the IRS explains, this is a deduction with income limitations, not a blanket elimination of taxes on Social Security. For high-income retirees, it may provide little or no benefit. But the larger point is that taxation should be part of the claiming decision from the start.

Why delaying can create a tax-planning opportunity

Consider a couple retiring at 64 with substantial taxable investments, traditional IRAs, and Roth accounts. If they delay Social Security, they may have several years with little or no wage income and no Social Security benefits. That period can present opportunities to make carefully planned withdrawals from traditional retirement accounts or convert portions of an IRA to a Roth IRA.

The idea is to manage taxable income while the household has more flexibility, potentially reducing future required distributions and improving the after-tax position of surviving spouses or heirs. There is no guarantee that delaying Social Security makes such conversions attractive. The results depend on the tax brackets involved, investment gains, future tax rates, and other income. Large Roth conversions can also trigger higher Medicare premiums.

Nevertheless, for households with significant tax-deferred retirement assets, the interaction between claiming age and tax planning can easily be more important than a simple break-even calculation.

Don't forget Medicare

You generally become eligible for Medicare at 65 whether or not you've started Social Security. Delaying Social Security does not automatically mean you should delay Medicare enrollment. Depending on your existing employer health coverage, late enrollment can create penalties or coverage gaps.

Higher-income retirees also face Medicare income-related premium adjustments, commonly called IRMAA. Medicare generally looks at income from two years earlier. A major Roth conversion, large capital gain, or other increase in income can raise Part B and prescription drug premiums. And after the death of a spouse, the surviving partner may encounter less favorable single-filer income thresholds.

These are not reasons to avoid sensible claiming or tax strategies. They are reasons to evaluate the full after-tax household result rather than focusing only on Social Security's gross monthly payment.

What if you're still working?

For executives, business owners, physicians, and professionals who continue working into their 60s, claiming early can be especially unattractive. 

Before full retirement age, Social Security applies an earnings test. In 2026, if you're below full retirement age for the entire year, the general earnings limit is $24,480. Social Security withholds $1 in benefits for every $2 of covered earnings above that amount. For someone reaching full retirement age during 2026, a higher $65,160 limit applies to earnings in the months before reaching that age, with $1 withheld for every $3 above the limit. Once you reach full retirement age, the earnings test no longer applies.

Investment income generally does not count for this earnings test. Wages and net self-employment income do. Benefits withheld under the earnings test aren't necessarily lost forever. Social Security adjusts benefits at full retirement age to account for months in which benefits were withheld. But the rules still complicate cash flow and can reduce the advantage of claiming while earning a substantial salary.

Someone collecting a $2,100 monthly benefit at 62 while earning $100,000 annually might have their entire year's benefit withheld, apart from situations where special first-year rules apply.

For high-income individuals still working, starting Social Security at 62 often accomplishes very little.

Social media claim #4: "Use the secret Social Security loophole to double your benefit"

Some social media advice recycles claiming strategies that were available years ago. 

Two common examples involve collecting spousal benefits while allowing your own retirement benefit to grow, or having one spouse file and suspend benefits so the other spouse could receive spousal payments.

Changes enacted in 2015 eliminated most of the advantages of these techniques for today's prospective retirees. Under current rules, people subject to the newer deemed filing provisions generally cannot choose to receive only a regular spousal benefit while separately accumulating delayed retirement credits on their own eligible retirement benefit.

And when a worker voluntarily suspends retirement benefits, regular benefits to family members on that record are generally suspended as well, with exceptions such as qualifying divorced-spouse benefits.

Survivor benefits are different, as discussed earlier.

In short, be skeptical of videos promising a little-known strategy that allows married couples to collect two full benefits simultaneously while both continue growing. There are legitimate nuances in the rules, but much of the supposedly secret information online is outdated.

Can you change your mind after claiming?

Sometimes.

If you recently started retirement benefits, Social Security may allow you to withdraw your application within the applicable 12-month period. This is generally permitted only once and requires repayment of benefits received, including certain payments and withholdings connected to the claim.

If you've reached full retirement age but are not yet 70, you may also be able to suspend your own retirement benefits and earn delayed retirement credits during the suspension. But the resulting benefit is not necessarily identical to what it would have been had you never claimed early, and suspension can affect benefits paid to eligible family members.

These are useful corrective tools—not reasons to make the original decision casually.

When claiming early actually makes sense

There are circumstances where claiming at 62, or before 70, is a sound decision.

The clearest case involves serious health concerns and no significant survivor-benefit considerations. If you're single, have a materially shortened life expectancy, and have no spouse or other eligible dependents who might benefit from your record, waiting for a larger lifetime payment may not be worthwhile. Early benefits can improve your current quality of life, preserve investments, fund experiences, or support family members while you're alive.

Even affluent people sometimes face liquidity constraints. Someone may own valuable real estate or an interest in a closely held business but have limited readily available cash. Receiving Social Security could reduce pressure to sell assets at an unfavorable time.

Another legitimate motivation is estate preservation. Because Social Security retirement benefits generally stop at death and cannot be bequeathed like stocks or an IRA, collecting earlier may allow someone to retain or invest more assets that can ultimately pass to heirs. That matters particularly to people with strong bequest goals and shorter expected lifespans.

There are also circumstances where collecting one spouse's smaller benefit early while allowing the larger benefit to grow is a sensible household strategy.

The mistake is not claiming early. The mistake is claiming early because of a simplistic rule, without comparing the realistic alternatives.

What Social Security has to do with estate planning

At first glance, Social Security seems separate from estate planning. You can't name your trust as the beneficiary of your monthly retirement check. Your children generally cannot inherit the right to collect your remaining retirement benefits simply because money was paid into the system during your career.

Your retirement benefit ends when you die. No retirement benefit is payable for the month of death, even if death occurs near the end of that month. Eligible survivors may have their own separate entitlements.

But those features are exactly why Social Security belongs in estate planning discussions.

1.  A larger survivor benefit can protect the estate

Suppose a married couple has $6 million in investments. The higher-earning spouse delays Social Security until 70. Later, that spouse dies, leaving the survivor with a larger monthly benefit. Every additional dollar of Social Security income the survivor receives is potentially a dollar that doesn't have to be withdrawn from investments. Over 15 or 20 years, that can help preserve assets for children and grandchildren. In this sense, delaying Social Security may support an estate plan even though Social Security itself isn't inherited as property.

2.  Early claiming may preserve transferable investments

There is a genuine competing argument. If someone claims Social Security early and uses the payments to cover living expenses, that person might leave more money invested in accounts that can be passed to heirs. For someone with poor health and no eligible surviving spouse, this approach may be superior. But it is not automatically better. The answer depends on investment returns, taxes, lifespan, the types of accounts being preserved, and whether family members are eligible for survivor benefits. Traditional IRAs, Roth accounts, and taxable brokerage accounts can also produce very different consequences for heirs.

3.  Estate documents need to reflect real Social Security entitlements

A comprehensive estate plan should take account of whether the surviving partner is legally eligible for benefits, whether the deceased was previously married, whether dependent children might qualify, and whether there are documentation issues that could delay claims. A spouse or former spouse may need marriage certificates, divorce decrees, death certificates, or other records to establish eligibility. These are practical matters that are much easier to address before a death or incapacity.

4.  More money isn't always the only objective

Affluent families often evaluate strategies by the wealth remaining for their heirs. That's understandable, but it's only one measure of success. A surviving spouse who lives to 98 may place far greater value on another $1,500 of reliable monthly income than on a modestly larger inheritance for adult children who are already financially secure. The family should be explicit about what matters most: current consumption, survivor security, lifetime financial independence, or maximum inheritance. Different priorities can produce different claiming decisions.

A practice framework for making the decision

After reviewing the rules, a useful starting point is to separate households into a few broad categories:

• Healthy, financially secure single retiree: Delaying—often until 70—deserves serious consideration, especially where longevity protection matters more than maximizing an inheritance.
• Married couple with one substantially higher earner: Strongly consider delaying the higher earner's benefit, often until 70, particularly if the lower earner is younger or likely to outlive the higher earner.
• Both spouses have substantial benefits: Compare multiple combinations of claiming ages. The larger survivor benefit still matters, but the best strategy may depend heavily on ages and earnings differences.
• Single person in poor health, with no eligible survivors: Earlier claiming may be a rational and financially preferable choice.
• Widowed, divorced, remarried, or unmarried household: Verify eligibility and switching options before applying. Relationship history can materially change the answer.
• Business owner or professional still earning significant income: Evaluate the earnings test, continued earnings history, income taxes, and Medicare effects.
• Household with eligible children or a dependent adult child with a disability: Consider potential family benefits, which may justify claiming earlier than a simple retirement-only calculation suggests.

These are starting points, not automatic rules.

Before deciding, obtain current estimates from your personal Social Security account. Check the underlying earnings record and adjust projected future earnings if you plan to stop working before you begin benefits.

Then compare the options using realistic cash flows, taxes, investment scenarios, and both spouses' potential lifespans. A comparison that considers only the first 10 or 15 years of retirement is incomplete. For affluent households in particular, it is reasonable to stress-test scenarios extending into the late 90s.

Also revisit your estimates if you've worked in public employment covered by an alternative pension system. The Social Security Fairness Act, signed in January 2025, repealed the former Windfall Elimination Provision and Government Pension Offset for benefits payable from January 2024 onward. Some earlier projections based on those reductions may now be outdated.

The bottom line: Don't confuse getting more checks with making a better decision

Social Security is unusual because taking less money now can produce more financial security later. That is the central tradeoff. The internet tends to frame the decision as a competition: claim at 62 and invest aggressively, or wait until 70 and maximize your government check.

Real financial planning is more subtle.

A wealthy single person in poor health may rationally claim at 62. A healthy married executive with a substantially younger spouse may have compelling reasons to wait until 70. A widowed professional may benefit from collecting survivor benefits first and switching to a larger personal benefit later. A divorced retiree may discover an entitlement they didn't know existed. An unmarried couple may discover that decades of shared financial life have not created the survivor protection they assumed.

For affluent retirees, a balanced approach is to treat Social Security as a source of long-term financial resilience rather than an investment to be maximized in isolation. If you have the financial resources to defer benefits, particularly on the higher earner's record in a marriage, the larger inflation-adjusted payment is frequently worth serious consideration.

But don't make the decision based on fear of insolvency, a rosy investment-return assumption, or the belief that everybody should wait until 70. The objective isn't to win a mathematical race against the Social Security Administration. It's to arrange your income, investments, taxes, and family protections so that you—and the people who depend on you—have the best financial position throughout retirement, however long it lasts.

And that is a much more worthwhile goal than simply collecting the first possible check.
