Accounts Payable and Accounts Receivable help you answer two questions:

  • How much do I owe?
  • How much am I owed?

When you understand both clearly, you can make better financial decisions and keep your business running smoothly.

Accounts Payable

Accounts Payable is the money your businesses owes to suppliers for goods or services purchased on credit. It appears as a current liability on your Balance Sheet and usually requires payment with 30, 60 or 90 days.

This includes:

  • Supplier invoices
  • Utilities
  • Rent
  • Service costs

For example: If you receive office supplies with a £1,000 invoice, this amount remains in Accounts Payable until you settle it.

Simply, it represents your unpaid bills.

Accounts Receivable

Accounts Receivable is the money customers owe your business for goods or services you have already provided. It appears as a current asset on your Balance Sheet and usually converts into cash within 30 to 90 days. This includes all outstanding sales invoices.

For example: If you send a client a £1,000 invoice, this amount sits in Accounts Receivable until payment arrives.

Simply, it represents your unpaid customer invoices.

Differences Between Accounts Payable and Receivable

While both relate to credit transactions, they serve opposite roles within your business.

Accounts Payable is the money you owe to suppliers; reducing cash flow when payments leave your account.

Accounts Receivable is the money owed to you by customers; increasing your cashflow when payments arrive.

How Accounts Payable and Receivable Work Together

Accounts Payable and Accounts Receivable link closely in everyday business activity. Every transaction involves both sides.

For example: When you buy goods, you create a payable. When you sell goods, you create a receivable.

When both processes run smoothly, your business benefits from steady cash movement. However, cash flow issues can arise if one side falls behind.

Managing Accounts Payable

You can improve your Accounts Payable process with a few simple steps:

  • Track all invoices and due dates carefully
  • Verify invoices before approving payments
  • Negotiate favourable payment terms where possible
  • Take advantage of early payment discounts
  • Use accounting software to automate reminders and payments
  • Maintain strong relationships with suppliers

Additionally, you should align payment dates with your incoming cash where possible. This helps you keep control of your working capital. As a result, you manage cash outflows more efficiently and avoid unnnecessary costs.

Managing Accounts Receivable

Managing your Accounts Receivable focuses on getting paid quickly and reducing delays:

  • Send invoices promptly after delivering goods or services
  • Include clear payment terms and instructions
  • Offer simple and flexible payment options
  • Follow up on overdue invoices without delay
  • Carry out credit checks for new customers where needed
  • Offer small discounts to encourage early payment

You should also monitor your ageing report regularly. This report shows which invoices remain unpaid and helps you take action quickly. In turn, these steps improve your cash inflow and reduce the risk of bad debts.

Supporting Making Tax Digital

From 6 April 2026, Making Tax Digital for Income Tax begins in phases for many sole traders and landlords.

While Accounts Payable and Accounts Receivable do not replace tax filing, they support accurate digital record-keeping:

  • Digital records must stay organised and up to date
  • Quarterly updates rely on accurate transaction data
  • Clear records reduce errors and delays

The Cost of Getting It Wrong

Late payments now carry higher costs under current HMRC penalty rules:

  • 3% penalty after 15 days
  • 3% additional penalty after 30 days
  • 10% annual interest from day 31

Because of this, careful payment planning has become more important than ever.
