Unpaid costs are one of the most common sources of confusion in small business accounting. Many business owners struggle to distinguish between accrued expenses and accounts payable, even though both directly affect profit, cash flow, and financial reporting accuracy.
Understanding the difference between accrued expenses vs accounts payable is essential for maintaining clean books, especially under accrual accounting. When applied correctly, it helps businesses avoid overstated profits, improve month end closing, and stay compliant with Singapore’s record keeping requirements.
Both are liabilities. Both represent money your business owes. But they are not the same. The key difference is simple:
Accrued expenses are costs incurred but not yet invoiced. Accounts payable is costs where the invoice has already been received but not yet paid.
Understanding this difference helps small businesses close their books more accurately, manage cash flow better, and avoid overstating profit.
Accrued expenses are costs your business has already incurred but has not yet received an invoice for.
Under accrual accounting, expenses should be recorded when the goods or services are received, not only when cash is paid. This helps your financial statements reflect the actual cost of running the business during that period.
Common examples of accrued expenses include:
For Singapore businesses, proper record keeping is important because companies must maintain financial transaction records, source documents, accounting records, schedules, bank statements, and related documents for at least 5 years from the relevant Year of Assessment.
Imagine your company uses electricity throughout June. By 30 June, you have used the electricity, but the utility bill has not arrived.
Based on past bills, you estimate the cost to be S$1,200.
This records the expense in June because the electricity was already used in June.
When the bill is later paid, the liability is cleared.
The important point is that the expense was recorded before the invoice arrived.
Accounts payable refers to money your business owes after receiving an invoice from a supplier, vendor, contractor, or service provider.
Unlike accrued expenses, accounts payable is usually based on a specific invoice. There is less estimation involved because the amount, supplier name, invoice date, and payment due date are already known.
Common examples of accounts payable include:
Accounts payable is usually easier to track because they are supported by invoice documentation.
Your business receives office supplies on 25 June. The supplier sends an invoice for S$500, payable within 30 days.
Because the invoice has been received, the business records the liability as accounts payable.
When payment is made, the payable is cleared.
Here, the business knows the exact amount because the invoice has already been received.
The distinction matters because it affects how accurate your profit, liabilities, and cash flow position appear at the end of the reporting period.
Both accrued expenses and accounts payable appear as current liabilities.
Accounts payable is usually shown as its own line item. Accrued expenses may appear separately or under accrued liabilities.
The key difference is the source of support:
Accounts payable is supported by invoices. Accrued expenses are usually supported by estimates, contracts, payroll records, usage records, or management calculations.
Both accrued expenses and accounts payable affect the income statement when the expense is recorded.
This means the expense is recognized when the business receives the goods or services, not necessarily when the payment is made.
For example, if your team worked in June but payroll is paid in July, the wage expense should still be recorded in June.
Accrued expenses and accounts payable also affect the operating activities section of the cash flow statement.
If these liabilities increase, they are generally added back to net income because the business recorded an expense but has not yet paid cash. If they decrease, they are generally deducted because cash has been paid for obligations recorded earlier.
Amazon’s 2024 Annual Report shows accounts payable and accrued expenses as separate operating cash flow adjustments, which is a useful example of how large companies distinguish these items in financial reporting.
1. Profit Can Look Higher Than It Really Is
If a business forgets to record accrued expenses, its expenses may be understated.
That means profit may look better than reality.
For example, if wages, utilities, or professional fees were incurred but not accrued at month end, the business may believe it had a more profitable month than it actually did.
2. Cash Flow Planning Becomes Less Reliable
Accounts payable and accrued expenses both represent future cash outflows.
If small businesses only look at bank balance, they may miss upcoming obligations.
This can lead to poor decisions such as:
Clean liability tracking gives business owners a more realistic view of available cash.
3. Month End Closing Becomes More Accurate
Accrued expenses are especially important during month end and year end closing.
A strong closing process should ask:
This reduces the risk of duplicated costs, missing expenses, or inaccurate management reports.
This may work for very simple cash tracking, but it does not give a complete view of business performance.
If an expense was incurred in June but paid in July, recording it only in July can distort both months.
Not every unpaid cost is accounts payable.
If there is no invoice yet, it is usually an accrued expense. Once the invoice arrives, it may be transferred or reclassified to accounts payable.
Accrued expenses are often estimated. If the actual invoice later arrives and the business records it again without reversing the accrual, the expense may be double counted.
A proper month end checklist should include accrual reversal and review.
Missing invoices can cause accounts payable to be understated.
This affects supplier payments, expense reporting, GST records where applicable, and cash flow planning. IRAS also states that businesses must support records and accounts with invoices, receipts, vouchers, and other supporting documents.

Accrued expenses and accounts payable are both unpaid business costs, but they are different in timing and documentation.
Accrued expenses are costs already incurred but not yet invoiced.
Accounts payable are costs already invoiced but not yet paid.
For small businesses, the distinction helps improve financial accuracy, cash flow visibility, month end closing, and compliance readiness.
A business that tracks both properly will have a clearer view of what it has earned, what it has spent, and what it still owes.
