Accrual vs Cash Accounting: Which Should Your Business Use?

Accrual vs cash accounting is the first real accounting decision every business makes — and one of the most consequential, because it changes what your profit numbers actually mean. The two methods can show wildly different results for the exact same business in the exact same month. This guide explains both methods in plain English, walks through the same transactions under each, covers the IRS rules on who can use which, and gives you a clear framework for choosing.

The core difference in one sentence

Cash accounting records revenue and expenses when money actually moves. Accrual accounting records revenue when it is earned and expenses when they are incurred — whether or not any cash has changed hands yet.

The same month, two very different pictures

Imagine a design agency in March: it invoices a client $20,000 for a finished project (payment due in April), collects $5,000 cash from an old February invoice, and receives a $3,000 contractor bill for March work that it will pay in April.

Neither number is "wrong" — but only the accrual view tells you March was a highly productive, profitable month. The cash view tells you what happened to the bank account. Run the business on cash-basis reports alone and busy months look poor, slow months look great, and pricing or hiring decisions get made on distorted signals.

What the journal entries look like

Under accrual, invoicing the client creates a receivable, and the contractor bill creates a payable:

Under cash basis, nothing is recorded until April, when the payments actually move. The receivable and payable simply do not exist on cash-basis books — which is exactly why cash-basis balance sheets show so little about what a business is owed or owes. New to debits and credits?

Cash basis: pros and cons

• Simple. If you can read a bank statement, you can keep cash-basis books.
• Tracks actual cash — you always know what is really in the bank.
• Can defer tax — income is not taxed until collected, and December expenses paid early reduce this year's taxable income.
• But it distorts profitability — timing of payments, not performance, drives the numbers.
• And it hides obligations — no receivables or payables means no early warning of a cash crunch already in motion.

Accrual basis: pros and cons

• True profitability — revenue matches the period it was earned and the costs of earning it.
• Required for growth — US GAAP, lenders, investors, and acquirers all expect accrual financials.
• Handles modern models — subscriptions, deferred revenue, inventory, and long-term contracts only make sense on accrual.
• But it is more work — invoices, bills, and adjusting entries must be recorded properly and on time.
• And profit ≠ cash — a profitable accrual P&L can coexist with an empty bank account, so you still need cash flow tracking alongside it.

What the IRS allows

Most small businesses may choose either method. The main restriction: C corporations (and partnerships with C-corp partners) averaging more than roughly $31 million in gross receipts over three years (the threshold is inflation-adjusted) must use accrual, and businesses carrying inventory generally need accrual treatment for inventory even if otherwise on cash basis. Once you adopt a method you must apply it consistently — switching requires filing Form 3115 with the IRS and recording one-time catch-up adjustments.

A very common and fully legitimate setup: accrual books for management, cash basis for tax (while eligible). You get accurate margins and trends for decisions, and the tax-deferral benefit of cash basis at filing time. Good bookkeeping software supports both views from the same records.

How to choose: a simple framework

• Solo service business, no inventory, invoices paid quickly? Cash basis is fine to start.
• Inventory, subscriptions, contracts, or customers on payment terms? Accrual — the cash view will actively mislead you.
• Planning to raise funding, get a loan, or sell the business? Accrual, starting now. Rebuilding history later is expensive, and diligence on cash-basis books is where deals stall.
• Not sure? Default to accrual. It is easier to produce a cash view from accrual books than the reverse.

The switch is routine — doing it alone is not

Moving from cash to accrual means recognizing receivables and payables that were invisible before, setting up deferred revenue if customers prepay, and filing Form 3115. For an experienced bookkeeper this is a well-worn path; done solo it is a common source of double-counted revenue and misstated first-year comparisons. If your business has outgrown cash basis, our guides on bookkeeping services for small business and what a bookkeeper costs cover what professional help looks like — and your books produce cleaner numbers from the very first accrual month.
