8 Accruals That Separate Mature Businesses From the Rest

Here's something we hear from small business owners all the time: "We're on cash-basis accounting, not accrual." More often than not, we open their books and find accounts receivable sitting right there on the balance sheet.

Surprise - that's an accrual.

A lot of owners believe they're on cash-basis because that's what their tax accountant told them. But your tax filing basis and your books don't have to be the same thing. You can file taxes on a cash-basis while keeping your internal books on an accrual or modified accrual-basis. The goal of your books is to help you run your business. The goal of your tax return is to calculate what you owe.

In practice, almost nobody is truly cash-basis, and almost nobody has all the accruals they actually need. Most fall somewhere in the middle - what accountants call modified accrual. They have AR because they invoice customers, maybe some AP, but the rest is inconsistent at best. The businesses that have it right usually got there because they came from a controller, a CFO, or a proper accounting function at some point. Everyone else is working with gaps, whether they know it or not.

Why Accruals Exist

Before diving into specific accruals, it's worth understanding the two core reasons they exist. Together they form the foundation of what accrual-basis accounting is actually trying to accomplish.

The Matching Principle

Revenues and the expenses that generate them should be recognized in the same period. Without this, your financials become nearly impossible to use for planning. Imagine paying a $30,000 annual insurance premium in January - on pure cash-basis, your January looks terrible and every other month looks artificially great. That's not useful information. The matching principle smooths those distortions out and gives you a true picture of what's happening in your business each month.

It works the other way too. Say you collect $120,000 from a client in January for a full year of services. On cash-basis, January looks incredible and February through December show no revenue at all - even though you're incurring expenses every single month to deliver on that contract. That's not a useful picture either. The matching principle says you earned $10,000 in January, $10,000 in February, and so on - matching the revenue to the periods in which you're actually performing the work.

The Obligation Principle

Accrual accounting also exists to capture what you're owed and what you owe - regardless of whether cash has changed hands. AR and AP are the most obvious examples, but it goes beyond that. Consider a rent security deposit. When you write that check, you have a choice: code it to rent expense and forget it, or record it as a deposit asset on your balance sheet because your landlord owes that money back to you someday. Recording it as a deposit is accrual thinking. You're capturing an economic reality - a future receivable - rather than just logging a cash outflow. The same logic applies to any situation where an obligation exists that your books should be tracking.

For service businesses, product companies, and anyone managing a team, getting both of these right is the difference between flying blind and actually running your business. Let's look at the accruals that matter most.

The 8 Key Accruals Every Small Business Should Understand

1. Accounts Receivable (AR) - Yes, This Is an Accrual

We'll start here because it surprises so many people. Accounts receivable - money your customers owe you for work you've already done or products you've already delivered - is an accrual entry. The moment you issue an invoice before payment arrives, you're practicing accrual accounting.

AR tells you how much revenue you've actually earned, not just what's hit your bank account. It's the foundation for understanding whether your business is growing, whether your collection process is working, and whether your cash flow gap is widening. If you have $200K in AR that's 90+ days old, that's a problem your cash-basis P&L is hiding entirely.

Pro Tip: Track Days Sales Outstanding (DSO) - how many days, on average, it takes to collect after invoicing. It's one of the clearest signals of whether your AR process is working.

2. Accounts Payable (AP) - You Probably Have More Than You Think

When we ask small business owners about accounts payable, a common response is "we don't really have any." But AP simply means invoices you've received where payment is still owed. At the most basic level, it's a reminder that you need to pay someone. Businesses without proper accounting processes typically skip recording it altogether - they just pay the bill when it comes and code the payment directly to expense. That means AP is consistently one of the most under-reported items on a small business balance sheet.

Not everything is AP. Automatic charges like a Netflix subscription or a monthly software fee that pulls from your card without an invoice - those just happen. But when a vendor sends you an invoice, that's AP. A good example is rent. Your landlord sends an invoice or statement, you owe it by the 1st, and there's a window between when the obligation exists and when you pay. That gap is exactly what AP captures.

Another important trigger for AP: when you receive an invoice from a vendor, that's also the right moment to collect a W-9 from them. You'll need it if payments cross the 1099 reporting threshold, and it's much easier to get upfront than to chase down at year-end. Recording the AP entry and requesting the W-9 at the same time builds a clean habit that saves headaches later.

Pro Tip: Even if a vendor pulls payment automatically, record the AP when the invoice arrives. It keeps your obligations visible and your books accurate - not just a log of what already left your bank account.

3. Payroll Accrual - Smoothing Out Your Largest Expense

Payroll is typically the largest expense for service businesses, and payroll periods rarely align perfectly with month-end. If your pay periods end on the 7th and 21st, you have wages earned but unpaid at the end of every month that aren't reflected in your books.

Without a payroll accrual, your labor costs are driven by payroll timing rather than actual effort. Most businesses run biweekly payroll, so most months have two pay runs - but depending on where those dates fall relative to month-end, the variance can be material enough to skew your metrics. And in the months where three pay runs land, payroll expense spikes hard, making that month look disproportionately expensive compared to the work actually performed. None of that reflects reality. A simple payroll accrual - estimating earned wages not yet paid at month-end - levels this out and makes your P&L genuinely useful for comparison.

Pro Tip: A precise accrual is always better, but it comes down to cost and effort. Whatever methodology you use, apply it consistently - and remember that something reasonably close is far better than not doing the accrual at all.

4. Deferred Revenue - Don't Count Money You Haven't Earned Yet

Deferred revenue is the flip side of AR: it's cash you've collected but haven't yet earned. This is common in subscription businesses, retainer arrangements, prepaid services, and any situation where customers pay upfront.

Recognizing all upfront cash as immediate revenue overstates your income and gives a false sense of how the business is performing. If a client pays $12,000 in January for a year of services, you've earned $1,000 in January - not $12,000. The remaining $11,000 is a liability (an obligation to deliver services) until you earn it month by month.

Pro Tip: Common places deferred revenue appears include annual software subscriptions, annual service contracts, upfront project deposits, and gift cards. If any of these sound familiar, check whether they're being recorded correctly.

5. Cost of Goods Sold / Cost of Services - Making Gross Margin Meaningful

Getting COGS right is arguably the most impactful - and most difficult - accrual challenge for small businesses. The goal is to match the costs of delivering your product or service to the revenue it generated, in the same period.

For product businesses, this means properly accounting for inventory: what did it cost to produce or acquire the goods you sold this month, not just what you purchased? For service businesses, it means attributing the labor and direct costs tied to the work delivered, not just what was paid out.

Gross margin is the single most important line on your P&L. It tells you how efficiently you're delivering your core product or service. If COGS is out of sync with revenue - from timing mismatches or expenses in the wrong bucket - your gross margin becomes meaningless, and all downstream analysis (pricing decisions, capacity planning, profitability by client or project) becomes unreliable.

Pro Tip: If your gross margin swings wildly month to month without a clear operational reason, the culprit is usually COGS timing. Catching it requires tying out your balance sheet accounts at month-end - inventory, WIP, unbilled costs, and similar accounts. Those reconciliations are the control that keeps COGS in check and your margin calculations accurate.

6. Prepaid Expenses - Spreading Out Large Upfront Costs

When you pay for something that benefits future periods - insurance, software subscriptions, rent deposits, prepaid marketing - the full payment shouldn't hit your P&L in the month you wrote the check. It should be spread across the months it benefits.

Annual insurance premiums, in particular, can be significant. Booking $18,000 of insurance expense in one month creates a massive distortion. Spreading it as $1,500/month gives you a stable, accurate picture of your true monthly operating cost.

Pro Tip: The upfront payment creates a prepaid asset on the balance sheet, which is then amortized (expensed) ratably over the coverage or service period. If you're booking large annual payments straight to expense, you're likely distorting several months at once.

7. Accrued Expenses - Everything Else You Owe

Beyond payroll and AP, there's a broader category of accrued expenses: costs you've incurred in a period that you haven't yet been invoiced for or paid. This includes utility bills that span month-end, professional service fees for work completed but not yet billed, sales commissions earned on closed deals, and interest on outstanding debt.

If you're trying to understand what it really cost to operate in October, you need to include October's expenses - not just the ones that happened to get invoiced and paid in October. Accrued expenses ensure the income statement reflects reality, not just the timing of paperwork.

Pro Tip: At month-end, ask yourself whether there's anything you've received or benefited from that you haven't yet recorded as a cost. If the answer is yes, you likely have an accrued expense that belongs in the current period.

8. PTO / Vacation Accrual - The Forgotten Liability

This one catches many small business owners off guard - particularly when an employee leaves. If your employees accrue paid time off that they can carry forward or cash out, that's a liability on your books. Every hour of earned-but-unused PTO represents a future cash obligation.

For a 10-person company where each employee has an average of two weeks of unused PTO, you might be sitting on $30,000–$50,000 in unrecorded liability. When an employee with significant accrued PTO is terminated, that obligation becomes immediately payable - in many states, by law. Companies that don't track this get blindsided.

Recording monthly PTO accrual also creates an incentive to manage PTO balances proactively, encouraging employees to take time off before it accumulates to uncomfortable levels.

One way some businesses sidestep this liability entirely is by moving to unlimited PTO. Without a defined accrual, there's nothing to track or pay out. It simplifies the accounting, but it's not the right fit for every company or culture. If you're weighing that option, we covered it in depth here: Is Unlimited PTO Right for Your Business?

Pro Tip: Recording the liability so it's visible encourages managing PTO balances throughout the year. This not only helps you manage a building liability, but benefits employees by actually taking time off to recharge.

The Bottom Line

Accrual accounting isn't just a technical exercise - it's the foundation of financial clarity. When your books reflect what you've earned and what you owe, regardless of when cash changes hands, you can actually use your financials to make decisions: when to hire, when to invest, where margins are eroding, and what's coming around the corner.

There's a clear dividing line we see in the businesses we work with. On one side are those operating without a proper accounting structure - books that are mostly a record of what went in and out of the bank, with gaps that make planning and decision-making a guessing game. On the other side are businesses that have made the transition to mature accounting processes. They have clean monthly financials, they know their margins, they can see what's coming, and that visibility is what allows them to manage confidently, grow deliberately, and scale without losing control.

The accruals in this article are a big part of what separates those two groups. If you're not sure where your books stand, Basis 365 Accounting offers a free Financial Operations Assessment to help you see exactly where things stand and where the gaps are.
