Cash vs. accrual accounting, shown in one messy month
The useful question is not which method makes profit look better. It is when each event belongs in the books, whether the method is allowed, and whether the business applies it consistently.
$3,000 still uncollected
$12,000 earned / $10,000 received
$5,000 January receivable collected
Includes $3,000 collected for December work and $7,000 collected for January work. The unpaid $5,000 invoice and $700 bill stay outside this simplified cash view.
Simplified service-business example. Tax exceptions, inventory, prepayments, and eligibility require separate review.
Cash accounting generally recognizes income when received and expenses when paid. Accrual accounting generally recognizes income when earned and expenses when incurred. In the same January activity below, cash-basis profit is $8,400 while accrual-basis profit is $9,700 because collections and payments cross month boundaries. Neither number is inherently more honest; the method, eligibility, cutoff, and consistency determine whether the result is supportable.
The rule changes timing, not the underlying business
The IRS describes an accounting method as the rules used to determine when income and expenses are reported. Cash and accrual are the two common methods. The same contract, invoice, bill, and payment exist under both; what changes is the reporting period.
That is why switching views without a bridge creates confusion. A cash report can be useful for liquidity while an accrual report can be useful for operating performance, but mixing recognition rules inside one ledger can double-count revenue or omit obligations.

Reconstruct January from dated events
The business completes $12,000 of January work and invoices it on January 31; $7,000 is collected in January and $5,000 arrives in February. It also collects $3,000 from a December invoice. January costs incurred are $2,300, but only $1,600 is paid during January.
Under the cash view, January receipts are $10,000 and January payments are $1,600. Under the accrual view, January revenue is $12,000 and January expense is $2,300. The December collection is not new January revenue under accrual accounting because it was earned earlier.

Use a bridge instead of arguing over the answer
Start with cash-basis profit of $8,400. Remove the $3,000 prior-period receivable collected in January, add the $5,000 January receivable collected later, and subtract the $700 January payable not yet paid. The result is $9,700 of accrual-basis profit.
The bridge forces every difference into a named balance-sheet account. If a timing explanation cannot be tied to accounts receivable, accounts payable, prepaid costs, deferred revenue, or another supported account, it is not a timing explanation yet.

| January event | Cash view | Accrual view | Balance-sheet trail |
|---|---|---|---|
| Collect $7,000 on January work | +$7,000 revenue | +$7,000 of $12,000 earned | No receivable remains for this portion |
| Invoice $5,000 collected in February | $0 January | +$5,000 revenue | $5,000 accounts receivable |
| Collect $3,000 December invoice | +$3,000 revenue | $0 January revenue | Clears prior accounts receivable |
| Pay $1,600 January costs | −$1,600 expense | −$1,600 of January cost | No payable for paid portion |
| Receive $700 January bill paid later | $0 January | −$700 expense | $700 accounts payable |
Eligibility and tax reporting need a separate decision
Publication 538 explains method rules, restrictions, inventories, consistency, and changes in accounting method. A management report can show both cash and accrual perspectives, but the tax method and any change to it require a facts-and-circumstances review.
Do not choose a tax method from this example. Entity type, gross receipts, inventory, special items, elections, and prior filings can matter. The practical bookkeeping job is to preserve transaction dates and evidence so a qualified tax professional can apply the current rules.

Close controls that prevent mixed-method books
Pick the reporting method for each official report and label it. Lock revenue recognition to an invoice, delivery, or service-completion policy. Maintain receivable and payable detail, and reconcile those subledgers to the general ledger every month.
Watch for the two classic duplicates: recording an invoice as revenue and then coding its deposit to revenue again, or entering a bill as expense and then coding the payment to expense again. Those errors are not cash-versus-accrual differences; they are duplicate accounting.
