Cash or accrual is presented as a decision you make once and live with. In practice most established businesses need both, and confusing which one you are looking at is a genuine source of bad decisions.
The distinction
Cash basis records revenue when money arrives and expenses when money leaves. Invoice a client in November, get paid in January, and it is January revenue.
Accrual basis records revenue when it is earned and expenses when they are incurred, regardless of cash movement. Do the work in November and it is November revenue, whenever the cheque lands.
Why cash basis is popular
Two honest reasons.
It is simpler. Follow the bank account and you are most of the way there.
It usually defers tax. Because you do not recognise revenue until collected, a business with meaningful receivables outstanding at year end pays tax later on cash basis than accrual. For a professional firm carrying 60 days of receivables, that deferral is real money.
Why cash basis lies to you
Cash basis tells you when money moved. It does not tell you whether you made money.
A consulting firm delivers a large project in June and gets paid in September. On cash basis, June looks like a disaster and September looks like a triumph. Neither reflects the work. If you are making staffing or pricing decisions from those months, you are reacting to collection timing rather than performance.
The distortion gets worse at exactly the wrong moment. A growing business collects more slowly than it bills, so cash basis systematically understates how well a growing firm is doing — and overstates it when growth stalls and receivables catch up.
The compromise most firms should run
Keep the books on accrual for management purposes. File on cash basis if you are eligible and it is advantageous.
This is not a trick. It is standard practice. Your accounting system maintains accrual records; the tax return is prepared on cash basis with a reconciling adjustment. You get accurate monthly numbers to run the business and the tax deferral where it is available.
The cost is that someone has to maintain both views, which is a bookkeeping question rather than a conceptual one.
When you do not get to choose
Eligibility for cash basis depends on your entity type, your gross receipts, and whether you carry inventory. The thresholds are indexed and the rules have particular treatment for tax shelters and certain entity types.
Practically: most professional service firms and small practices are eligible. Businesses carrying significant inventory frequently are not. It is worth confirming rather than assuming, because switching methods later requires a formal accounting method change rather than simply doing it differently next year.
What accrual reveals that cash hides
Work in process
For a law firm or agency, unbilled work is real value that cash basis cannot see. A firm can be highly profitable and cash poor simultaneously, and only accrual shows both halves.
Deferred revenue
Retainers and prepayments are cash you hold but have not earned. On cash basis it looks like a great month. On accrual it sits as a liability until the work is done, which is the truthful picture.
Real margin by period
Matching revenue to the costs incurred producing it is the only way to know whether a service line, a location or a client actually makes money.
The practical test
If your month-to-month results swing wildly and you cannot explain why from operations, you are probably looking at cash basis statements and reading collection timing as performance.
That is a fixable problem, and it does not necessarily require changing how you file.
