Accrual vs Cash Accounting: Which Method Fits Your Small Business?

Listen to this article

Every business has to decide when a sale or a bill “counts” in its books. Do you record it when the money moves, or when the work is done? That one choice is the difference between cash and accrual accounting, and it changes what your profit looks like month to month.

This guide explains both methods in plain English, shows the same month recorded both ways for an illustrative small business, and helps you decide which fits.

What Is Cash Accounting?

With cash accounting (also called the cash basis or cash method), you record income when you receive the money and expenses when you pay them.

If you finish a job in March but the customer pays in April, the sale shows up in April. If you buy supplies on a credit account in March and pay the supplier in May, the expense shows up in May.

It’s simple, and it matches your bank account closely. Most very small businesses and sole proprietors start here.

What Is Accrual Accounting?

With accrual accounting, you record income when you earn it and expenses when you incur them, no matter when cash moves.

The March job counts as March revenue, even though the money arrives in April. That unpaid amount sits in accounts receivable until it’s paid. The March supplies count as a March expense, and the unpaid bill sits in accounts payable.

Accrual accounting takes more bookkeeping, but it shows whether each month was truly profitable.

The Key Difference in One Table

	Cash accounting	Accrual accounting
Income recorded	When money is received	When it’s earned
Expenses recorded	When bills are paid	When they’re incurred
Tracks receivables and payables	No	Yes
Matches the bank balance	Closely	Not always
Shows true monthly profit	Less reliably	More reliably
Bookkeeping effort	Lower	Higher

Worked Example: A Small Catering Company

A catering company does a $9,000 wedding in June. The couple pays a $3,000 deposit in May and the remaining $6,000 in July. Food and staff for the event cost $5,000, paid in June. All figures are illustrative.

Month	Cash basis profit	Accrual basis profit
May	+$3,000	$0
June	−$5,000	+$4,000
July	+$6,000	$0
Total	$4,000	$4,000

Over the three months, both methods arrive at the same $4,000 profit. The difference is timing.

On the cash basis, June looks like a $5,000 loss, even though June was the month the work happened and the money was earned. May and July look like great months, when really nothing much happened. On the accrual basis, the whole $4,000 profit lands in June, when the wedding took place.

Under accrual, the May deposit is recorded as a liability (often called deferred revenue or customer deposits) until the event is delivered.

If the owner judged performance on the cash numbers, they might panic in June and celebrate in July for the wrong reasons. That’s the same trap covered in cash flow vs profit.

Who Can Use Which Method?

In the United States, most small businesses can choose, but there are limits:

• Small businesses generally may use the cash method. For tax years beginning in 2026, C corporations and partnerships with a C corporation partner must pass the IRS gross receipts test, which means average annual gross receipts of $32 million or less over the prior three years. Tax shelters can’t use the cash method.
• Inventory businesses that meet the same gross receipts test can often still use the cash method, though how inventory is handled has its own rules.
• Lenders and investors often want accrual-based financial statements, even if your tax return uses cash.
• Changing methods for tax purposes usually means filing IRS Form 3115.

Rules depend on your setup, so check with a tax professional before you switch. If you’re still choosing a business structure, see sole proprietor vs LLC.

Which Method Should You Choose?

Cash accounting usually fits if you:

• Get paid at the time of sale, like a barber or food truck.
• Have no or little inventory and few unpaid bills.
• Do your own books and want them simple.

Accrual accounting usually fits if you:

• Invoice customers on terms and wait to be paid.
• Hold inventory or take deposits for future work.
• Want accurate monthly profit, plan to borrow, or plan to sell the business.

Many owners use a middle path. They keep cash-basis books for taxes but run an accrual-style report each month, or at least keep a list of unpaid invoices and bills, so they can see what’s really going on.

Common Mistakes

1. Spending deposits as profit. On the cash basis, a deposit feels like income, but you still owe the work. Keep deposits for upcoming jobs separate.
2. Ignoring unpaid bills. Cash books can look healthy while supplier bills pile up. Track what you owe either way.
3. Mixing methods by accident. Recording some sales when invoiced and others when paid makes your reports useless. Pick one method and stick to it.
4. Switching without advice. Changing your tax method has paperwork and timing rules. Talk to your accountant first.
