What Are Accounts Payable?

Accounts payable, referred to as trade creditors in UK accounting, represent the amounts a business owes to its suppliers for goods and services received on credit. They are classified as a current liability on the balance sheet and are a central element of working capital management.

Managing accounts payable effectively means balancing the need to preserve cash with maintaining good supplier relationships and taking advantage of early payment discounts.

How Accounts Payable Arise

A payable is created whenever a business receives goods or services before paying for them. The typical purchase cycle is:

1. The business places an order with a supplier
2. The supplier delivers goods or performs the service
3. The supplier issues an invoice with agreed payment terms
4. The invoice is recorded in the purchase ledger as accounts payable
5. Payment is made within the credit period
6. The payable is cleared

Recording a Purchase on Credit

When a UK company receives a supplier invoice for £3,000 plus 20% VAT:

The full invoice amount, including VAT, is credited to accounts payable because the business owes the supplier the total. The input VAT can be reclaimed from HMRC on the next VAT return.

Accounts Payable on the Balance Sheet

Under FRS 102, accounts payable are presented within creditors: amounts falling due within one year on the balance sheet. A typical disclosure looks like:

Trade creditors represent the invoices received from suppliers that have not yet been paid.

The Purchase Ledger

The purchase ledger (also called the accounts payable ledger or creditors ledger) is the subsidiary ledger that maintains individual accounts for each supplier. It records:

• Invoices received
• Credit notes received
• Payments made
• The outstanding balance owed to each supplier

The total of all supplier balances in the purchase ledger must agree with the trade creditors control account in the general ledger. Regular reconciliation between these two is an essential internal control.

Supplier Statement Reconciliation

Suppliers periodically send statements showing their record of transactions. Comparing these against the purchase ledger helps identify:

• Invoices not yet received or recorded
• Payments not yet credited by the supplier
• Discrepancies in amounts
• Duplicate invoices

Payment Terms

Standard payment terms vary by industry. Common arrangements in UK business include:

Early Payment Discounts

Taking advantage of early payment discounts can generate significant savings. A 2% discount for paying 20 days early equates to an annualised return of approximately 36%, making it almost always worthwhile if cash flow permits.

Late Payment

Under the Late Payment of Commercial Debts (Interest) Act 1998, suppliers have the right to charge interest at 8% above the Bank of England base rate on overdue invoices. Additionally, they can claim fixed-sum compensation. Paying late damages supplier relationships and can restrict future credit availability.

Accounts Payable Process Controls

Robust internal controls over accounts payable protect against fraud and errors. Key controls include:

Invoice Authorisation

• Three-way matching: Compare the supplier invoice against the purchase order and the goods received note before approving payment
• Authorisation limits: Require managerial approval for invoices above specified thresholds
• Segregation of duties: Separate the roles of ordering, receiving, invoice processing, and payment

Payment Controls

• Payment runs: Process payments in batches on set days rather than ad hoc
• Dual authorisation: Require two signatories for payments above a certain value
• Bank reconciliation: Regularly reconcile the bank account against the ledger

Fraud Prevention

• Supplier verification: Verify bank details directly with suppliers before making first payments or when details change
• Duplicate detection: Use software checks to prevent paying the same invoice twice
• Audit trail: Maintain complete documentation from purchase order through to payment

Key Ratios for Accounts Payable

Creditor Days (Days Payable Outstanding)

Creditor days measures the average time taken to pay suppliers:

Creditor Days = (Trade Creditors / Cost of Sales) x 365

A creditor days figure significantly longer than the agreed payment terms suggests the business is paying suppliers late, which carries risks including supply disruption and reputational damage.

Payables Turnover Ratio

Payables Turnover = Cost of Sales / Average Trade Creditors

A lower ratio indicates the company is taking longer to pay. While stretching payables can benefit short-term cash flow, it must be balanced against supplier relationship management.

Accounts Payable and Cash Flow

Accounts payable represent expenses recognised in the income statement but not yet paid in cash. On the cash flow statement:

• An increase in accounts payable improves operating cash flow (the business is retaining cash longer)
• A decrease in accounts payable reduces operating cash flow (cash is being used to settle debts faster)

The interplay between accounts receivable and accounts payable determines the business’s cash conversion cycle, a critical measure of financial management effectiveness.

Cash Conversion Cycle

Cash Conversion Cycle = Debtor Days + Stock Days - Creditor Days

A shorter cycle means the business converts its working capital into cash more quickly. Managing accounts payable (extending creditor days without damaging relationships) is one lever for improving this metric.

VAT and Accounts Payable

When a VAT-registered business receives a supplier invoice that includes input VAT, it can reclaim this VAT from HMRC. The VAT element is debited to the VAT input account, not to the expense account.

Under Making Tax Digital (MTD), all VAT-registered businesses must maintain digital records and submit VAT returns from MTD-compatible software. The accounts payable records form part of the digital trail required by MTD.

Reverse Charge VAT

For certain supplies, such as construction services under the CIS domestic reverse charge, the buyer must account for the VAT rather than the supplier charging it. This requires a specific journal entry :

The net VAT effect is zero, but both input and output must appear on the VAT return.

Accounts Payable in Company Accounts

Companies House Disclosure

Companies filing accounts at Companies House must disclose creditors falling due within one year. For medium and large companies, this includes:

• Trade creditors as a separate line item
• Amounts owed to group companies
• Corporation tax and other tax liabilities
• Accruals and deferred income

Payment Practices Reporting

Large UK companies and LLPs (with more than 250 employees or meeting two of the three size thresholds) must publish biannual reports on their payment practices and performance, including:

• Average time taken to pay suppliers
• Percentage of invoices paid within 30, 60, and beyond 60 days
• Percentage of invoices not paid within agreed terms
• Late payment interest owed and paid

These reports are published on a government website and are publicly searchable, creating transparency and accountability.

Relationship with Other Balance Sheet Items

Accounts payable interact closely with several other items:

• Accruals : Where an invoice has not been received but the expense has been incurred, an accrual is recorded instead of a payable
• Prepayments : Payments made in advance before the goods or service are received sit on the opposite side of the balance sheet as current assets
• Provisions : Where the amount or timing of a liability is uncertain, a provision is recognised rather than a payable
• Equity : The overall level of creditors relative to equity indicates the business’s reliance on supplier financing

Effective accounts payable management ensures that liabilities are accurately stated, cash is deployed efficiently, and supplier relationships remain healthy.
