Accrued expenses vs accounts payable: what is the difference and why does it matter?

Both accrued expenses and accounts payable show up on your balance sheet as current liabilities. Both represent money your business owes but has not yet paid. And both appear frequently in small business bookkeeping in ways that are easy to confuse with each other, especially if you are managing your own records or if your bookkeeper has not explained the distinction clearly.

The difference comes down to one thing: documentation. Accounts payable is recorded when you have a supplier invoice in hand. Accrued expenses are recorded when you know a cost has been incurred but an invoice has not arrived yet.

That distinction sounds minor, but it produces meaningfully different entries in your books and reflects different stages in the same underlying process.

Accounts payable: the invoice has arrived

When a supplier or vendor sends you an invoice for goods or services you have already received, you record that obligation as accounts payable. The invoice is the triggering document. It confirms the amount, the vendor, the due date, and the nature of the expense. Everything is specific and documented.

A few examples: your office cleaning company sends a monthly invoice at the end of each month. Your supplier ships materials and invoices you for $4,800. Your attorney emails a bill for legal services rendered last quarter. Each of these produces a confirmed amount from a specific vendor, tied to a specific invoice, and each goes into accounts payable when you receive it.

The accounting entry is a debit to the relevant expense or asset account and a credit to accounts payable. When you pay the invoice, you debit accounts payable and credit cash. The expense has already been recognised; the payment simply settles the liability. No second expense is created at the time of payment.

Accrued expenses: the cost is real but the invoice has not arrived

Accrued expenses, also called accrued liabilities, cover costs your business has incurred within an accounting period but for which you have not yet received an invoice or made a payment. The cost is real and the obligation exists, but the formal documentation has not arrived yet.

Under accrual accounting, expenses are recognised in the period they occur, not the period you pay for them. This is the matching principle: expenses are matched to the period in which the business benefited from them. If your employees earn wages in December but payroll does not run until January 5, those December wages are an accrued expense on your December balance sheet. The obligation was incurred in December even though cash does not leave the account until January.

Other common accrued expenses include interest that has accumulated on a business loan between payment dates, utilities that cover a service period ending before the bill arrives, and professional services delivered before month-end but invoiced afterward.

The accounting entry for an accrued expense is a debit to the expense account and a credit to accrued liabilities, which is a separate current liability account from accounts payable. When the invoice eventually arrives and is paid, the accrual is reversed or trued up against the actual invoice amount. This two-step process is one reason accrued expenses require more discipline than accounts payable — they need an adjusting entry at month-end and a controlled clearance when the invoice clears. An accrual schedule that tracks each estimate, its owner, and its expected reversal or invoice date is the control that prevents omitted expenses and duplicate expenses from appearing side by side.

The practical difference in your books

The takeaway is straightforward. Accounts payable is easier to prove because the invoice exists. Accrued expenses improve period accuracy but require more judgment and follow-up to ensure estimates are supported and cleared correctly.

An illustrative example at month-end

Consider a business that receives a $4,800 materials invoice on December 28. Because the invoice is in hand, the bookkeeper records the materials purchase and credits accounts payable. The invoice is paid in January, so January cash activity clears the liability rather than creating a new January expense.

The same business's employees also work through December 31, but payroll is not processed until January 3. At the December close, the business records the December wage obligation as an accrued liability based on its payroll records and the hours worked. When payroll runs in January, that accrual is reversed or cleared. The contrast reveals the operating rule clearly: the invoice-backed supplier obligation is accounts payable, while the internally supported but not-yet-invoiced payroll obligation is an accrual.

Why this distinction matters for your business

Financial statement accuracy. If a business records only invoices received before the close, it can omit costs that have genuinely been incurred. That understates liabilities and expenses for the period and makes profit appear higher than it really is. A business can have a clean accounts payable ledger and still have incomplete liabilities if it has not considered payroll cutoffs, unbilled services, utilities, interest, or other costs incurred before the reporting date. Accrual accounting exists to match income and expenses to the correct year.

Management decisions. An omitted accrual can distort your gross margin, operating profit, cash planning, and month-to-month comparisons. The mechanism is straightforward: the expense is pushed into the later invoice month even though the business consumed the service or labour in the earlier period. A documented accrual keeps your performance report aligned with the period that generated the cost.

Tax reporting requires a separate analysis. Book accruals and tax deductions are not the same thing. The IRS publication on accounting methods states that under an accrual method, the all-events test requires that all events determining the right to income or the fact of the liability have occurred, and that the amount can be determined with reasonable accuracy. An additional economic-performance requirement also applies to certain accrued expenses before a tax deduction is available. Do not assume that every accrual you record in your books automatically creates an equivalent tax deduction in the same period. This is a question for your accountant to answer based on the type of expense, your entity, and current IRS rules.

When accrual accounting is required

The IRS allows many small businesses to choose between cash and accrual accounting. The cash method generally means reporting income when received and deducting expenses when paid. The accrual method generally means reporting income when earned and expenses when incurred, regardless of cash timing.

For tax years beginning in 2026, the IRS guidance includes an inflation-adjusted gross-receipts threshold of $32 million for the limitation on use of the cash method. Whether your business may use cash basis or must use accrual depends on your entity type, whether you maintain inventory, tax shelter status, and other facts. The Form 3115 process applies when a business changes its overall accounting method or the treatment of a specific item, but the applicable procedure — automatic or non-automatic — depends on your situation. Confirm which method applies to your business and whether any change requires a formal application with your tax adviser rather than relying on a software setting alone.

A practical month-end checklist

Keeping accounts payable and accrued expenses accurate at each close comes down to a short repeatable review:

Reconcile the accounts payable balance to the general ledger and confirm every open invoice has a vendor, amount, due date, and approval on record. Review unpaid invoices alongside receiving records to confirm goods or services were actually received. Search for unbilled costs using payroll cutoffs, contracts, recurring bills, interest schedules, and service milestones. Record each accrual with its period, the calculation behind the estimate, who owns it, who reviewed it, and the expected reversal or invoice date. Check that the same cost is not already sitting in accounts payable before adding it as an accrual. Reverse, clear, or true up the accrual when the invoice arrives. Confirm after payment that the expense was not recorded twice.

How Inkle helps

Inkle's professional bookkeepers handle payables and receivables and close the books monthly. The platform supports accrual-based bookkeeping through journal entries, and AI categorises transactions with a real bookkeeper reviewing the details each month. Accounts payable are recorded as invoices arrive, and accruals are applied at the close so that your balance sheet reflects your actual liabilities at each month-end rather than only the invoices that happened to come in before the reporting date.

Before you start, confirm with Inkle that the accrual workflow for your specific situation, including which costs require monthly accruals and how reversals are handled, is covered under your plan and engagement terms.
