Accrual accounting records income when it is earned and expenses when they are incurred, even when cash changes hands later. This guide explains the approach, provides a worked example, and outlines what businesses should consider before adopting it.
If you are closing the books with an unpaid customer invoice or an unbilled supplier service in front of you, the bank statement alone will not place the activity in the correct period. Your next check is when the work was completed or the service was received.
What Is Accounting Under the Accrual Basis?
Accounting under the accrual basis records the economic effect of a transaction in the period when the underlying activity occurs. A completed service creates income even if the invoice remains unpaid.
An expense arises when a business receives goods or services, not when it sends payment.
This accounting approach connects related income and expenses to the same reporting period. The resulting income statement describes operating activity rather than only movements through a bank account.
The Financial Accounting Standards Board standards portal provides access to United States generally accepted accounting principles (GAAP) resources.
This approach does not ignore money received or paid. It records both the operating event and the later settlement.
That distinction leads directly to understanding an accrual.
What Is an Accrual?
An accrual is an accounting entry for income earned or an expense incurred before the related cash receipt or payment. It recognizes an obligation or economic benefit that exists at the reporting date, even if the final invoice or settlement arrives later.
Common examples include employee wages earned before payday, interest accumulated between billing dates, and professional services received before an invoice is issued. Accrued revenue may arise when a business completes work before billing its customer.
An accrual is usually reversed or settled when the actual transaction enters the accounting records. This process helps prevent income or expenses from being recorded twice, but it requires documented assumptions and a consistent period-end review.
These entries directly affect the financial statements.
How Does Accrual Accounting Affect Financial Statements?
Accrual accounting affects financial statements by recognizing assets, liabilities, revenue, and expenses according to economic activity rather than settlement timing. The income statement reports earned revenue and incurred expenses.
The balance sheet carries unsettled amounts such as accounts receivable, accounts payable, and accrued liabilities.
Suppose ABC Co. completes $3,000 of work in March, invoices the customer in April, and receives cash in May. The company records $3,000 of revenue and an accounts receivable asset in March.
In May, the cash receipt reduces the receivable and increases cash. It does not create revenue again.
The same accounting logic applies to costs. If ABC Co. receives $900 of services in March but pays in April, it records a $900 expense and liability in March.
These examples illustrate transaction timing, not personalized tax treatment. The next step is to examine the mechanics of the method.
How Does the Accrual Method Work?
The accrual method works by identifying an economic event, assigning it to the correct reporting period, recording the appropriate entry, and settling or adjusting that entry later. Each accounting step should leave an audit trail showing the source, amount, date, responsible reviewer, and basis for any estimate.
A typical accounting process follows this sequence:
- Identify completed sales, received services, or incurred obligations.
- Determine when the revenue was earned or the expense arose.
- Record the transaction in the relevant accounts.
- Review estimates and supporting documents at period end.
- Reverse, adjust, or settle the entry when the actual remittance or invoice appears.
This approach depends on cut-off controls. A business must distinguish activity belonging to the current period from activity belonging to the next one.
Estimates may have low, medium, or high uncertainty depending on contract clarity, available documentation, and variability in the final amount.
The accounting approach also applies to deferrals. For example, a customer payment received before the business performs the work may be recorded as a liability rather than immediate revenue.
With the mechanics established, the next issue is why businesses use accrual accounting.
Why Do Businesses Use Accrual Accounting?
Businesses use accrual accounting to align operating activity with the period in which it occurs. The method can present receivables, obligations, revenue, and expenses more completely than records based only on bank movements.
For owners and managers, accrual accounting can support clearer comparisons between reporting periods because settlement timing has less influence on reported performance. It also shows working-capital items that affect the business, including unpaid customer invoices and bills awaiting settlement.
For investors, lenders, and a chief financial officer (CFO), this accounting view can clarify how current operations affect future collections and payments. The United States Securities and Exchange Commission guide to financial statements explains the roles of the income statement, balance sheet, and cash flow statement in evaluating a company.
However, accrual accounting requires estimates, reconciliations, and period-close processes. These requirements become clearer when the method is compared with cash accounting.
Accrual Accounting vs. Cash Accounting
Accrual accounting records activity when it is earned or incurred, whereas cash accounting records revenue and expenses when money is received or paid. The difference is timing, not necessarily the total amount recognized over the full life of a transaction.
| Accounting issue | Accrual method | Cash method |
|---|---|---|
| Customer sale | Records revenue when earned | Records revenue when cash arrives |
| Supplier cost | Records an expense when incurred | Records an expense when payment occurs |
| Unpaid invoice | Creates a receivable or payable | Usually waits for settlement |
| Period-end work | Requires adjustments and estimates | Usually involves fewer timing entries |
Cash accounting may be easier for some small businesses to maintain because it follows bank activity closely. Accrual accounting may provide a fuller financial picture when sales, purchases, subscriptions, inventory, or long settlement terms cross reporting periods.
Book accounting and tax reporting are separate questions. Eligibility to use a particular tax accounting basis depends on current rules and the taxpayer’s circumstances.
United States businesses should verify the applicable requirements with the Internal Revenue Service (IRS) and a qualified adviser before changing methods. The practical choice also depends on the systems supporting the records.
What Systems Support Accrual Accounting?
Systems support accrual accounting by capturing source documents, posting entries, tracking unsettled balances, and preserving evidence of review. Useful accounting systems commonly include a general ledger, accounts receivable, accounts payable, bank reconciliation, and period-close controls.
Automation and artificial intelligence (AI) systems may assist with document extraction, transaction classification, or proposed entries. They do not remove the responsibility to verify the accounting period, amount, account, and supporting evidence.
Automating these processes is a controlled workflow and does not ensure correct financial reporting on its own.
A suitable accounting setup should match the complexity of the business. Small, medium, and large environments may require progressively stronger approval paths, integrations, access controls, and reconciliation processes.
The business using the system remains responsible for the final decision.
Is Accrual Accounting Right for Your Business?
Accrual accounting is generally worth considering when a business needs period-based financial reporting, carries receivables or payables, or regularly has transactions that cross reporting dates. The method may also be appropriate when a reporting framework, lender, investor, contract, or tax rule requires it.
Before choosing this accounting method, review how the business bills customers, purchases services, manages inventory, closes its books, and produces financial reports. Confirm which records the team can maintain consistently and which estimates require approval.
Businesses should also separate management reporting needs from tax filing requirements. Consult current FASB standards for GAAP questions, the IRS for federal tax rules, and an appropriate accounting professional for advice based on the business’s specific circumstances.
The decision returns to the core definition: accrual accounting records economic activity when it occurs. Choose it when that timing gives the business the clearest supportable view of its obligations, performance, and next financial decision.
Use the invoice, service date and reporting period together before deciding when to record revenue or expense.
