Cash or Accrual: Which One Your Books Should Be On

Two businesses do identical work in March. One shows $50,000 of March revenue. The other shows $12,000. Neither is wrong — they are just answering different questions, because they are on different accounting methods.

This is one of the few genuinely structural choices in bookkeeping, and it is usually made by accident.

Cash basis

Revenue counts when money arrives. Expenses count when money leaves. That is the whole rule.

Its virtue is that it never lies about liquidity. If the P&L shows a good month, the money is in the account, because that is what "a good month" means under this method.

Its weakness is timing distortion. Invoice $50,000 in March and collect it in May, and March looks terrible while May looks extraordinary. Neither reflects the work. For a business with any lag between doing the job and getting paid, cash-basis monthly reports are noisy in a way that makes trends hard to read.

Accrual basis

Revenue counts when it is earned. Expenses count when they are incurred. Money movement is a separate matter, tracked on the balance sheet as receivables and payables.

Now March shows the $50,000 you actually earned in March, sitting in accounts receivable until it is collected. The P&L describes the business's performance rather than its bank timing.

The weakness is the mirror image: accrual reports can look healthy while the account runs dry, because earning and collecting are decoupled. Accrual demands that you also watch the balance sheet. If you only read the P&L, accrual will let you walk into a cash problem with a smile on your face.

How to choose

Cash basis usually fits when you get paid at the point of sale, carry no inventory, and have few long-running commitments. A salon, a solo consultant billing on completion, most service businesses collecting immediately.

Accrual usually fits when there is a real gap between doing the work and being paid, when you hold inventory, when you take deposits, or when you have work in progress spanning months. Contractors, agencies, wholesalers, anyone invoicing on terms.

Two things push the decision harder than preference. Holding inventory generally means accrual is the only method that produces a sensible gross margin, because cash basis expenses inventory when purchased rather than when sold. And lenders and buyers will nearly always want accrual statements — a bank evaluating a loan wants to see earned revenue, not collection timing.

The pragmatic answer: both

Most accounting software will produce either report from the same underlying data, provided the data is captured properly. That means invoices entered when issued, bills entered when received, rather than transactions recorded only when they hit the bank.

Capture it that way and you can run accrual for management and lending, and produce cash-basis figures when your tax professional asks for them. Capture it the lazy way — bank feed only — and you are locked into cash basis whether it suits you or not, because the data to build accrual reports was never recorded.

That is the real decision, and it is made at setup rather than at year end. It is one of the things we get right during setup and onboarding, and one of the more common things needing repair during a cleanup.

Which method you report on for tax purposes is a question for your CPA or enrolled agent — there are eligibility rules, and switching later requires their involvement. What we do is make sure the underlying records support whichever answer they give you.

What each method hides

Cash basis hides obligations. Bills you have received and not paid do not appear, so a month can look profitable purely because payment timing fell well. It also hides receivables, so work delivered and not yet collected is invisible.

Accrual hides cash. A business can show strong profit while running out of money, because revenue is recognized when earned rather than when collected. That is why an accrual business still needs a cash view alongside it.

Why lenders and buyers prefer accrual

Accrual matches revenue to the costs of producing it, which is what makes margin meaningful. Cash basis can put revenue in one month and its costs in another, producing a picture that reflects timing rather than performance.

Anyone assessing the business — a lender, a buyer, an investor — will normalize to accrual. Running accrual internally means their analysis and yours start from the same place.

Using both

Many businesses run accrual books and report cash basis for tax where permitted. That is a normal arrangement, and modern accounting software will produce either view from the same underlying data.

What does not work is maintaining the books loosely and deciding the method at year end. The method determines what has to be recorded during the year, particularly around receivables, payables and deferred revenue.

The decision is your CPA’s

Size, industry, inventory and entity type all bear on what is permitted and what is advantageous. Switching later has tax consequences and usually requires a formal change, so it is worth getting right early rather than revisiting.
