Accounts payable management means knowing which supplier bills are valid, how much remains unpaid and when payments should be made. It is more than maintaining a list of bank transfers. A useful payable ledger connects orders, deliveries, invoices, approvals, credit notes and settlements.

The aim is to avoid paying twice, overlooking a genuine bill or building a cash plan around an incomplete picture of what you owe. A good routine also helps preserve supplier relationships because queries are raised before the payment date rather than after a delivery is stopped.
Use one route for incoming bills
Create a shared invoice address or capture process and tell suppliers where to send documents. Record invoices promptly, even when approval is outstanding, using a status that prevents accidental payment. Leaving an unapproved bill in someone’s inbox hides a potential liability from the business.
Check the supplier, invoice number, date, amount, description and payment terms. Search for an existing entry before adding another copy. Duplicate detection should use supplier and invoice reference as well as value: two legitimate invoices can have the same amount.
Keep supplier statements separate from invoices. A statement is useful for checking balances, but entering both a statement and the invoices it lists can duplicate the debt. If an invoice on the statement is missing, request a copy and investigate it.
Match the bill to what was agreed and received
For goods, compare the invoice with the order and delivery record. For services, ask the person responsible to confirm the work and agreed price. Check quantity differences, delivery charges and invoices that cover several periods.
Give disputed invoices an owner and a clear explanation. “On hold” is insufficient if nobody knows whether the business disputes £20 or the whole £2,000 bill. Ask for a corrected invoice or credit note where appropriate and retain the correspondence.
| Stage | Practical control |
|---|---|
| Capture | Unique reference and document attached |
| Check | Supplier, amount and duplicate search |
| Approval | Named person confirms purchase or service |
| Query | Reason, disputed amount and follow-up date |
| Schedule | Due date and cash availability reviewed |
| Payment | Approved details and authorised release |
| Reconcile | Payment matched and supplier balance checked |
Build the payment schedule from due dates
Sort approved bills by contractual due date, not simply invoice arrival. Include direct debits so they are not also placed into a manual payment run. Show overdue, due soon, disputed and not-yet-approved amounts separately.
Compare the schedule with the cash forecast. If available cash is insufficient, decide early which suppliers to contact and what revised arrangement to propose. An internal decision to delay payment does not change the supplier’s agreed terms; document any agreement reached.
Avoid promising dates based on invoices you merely hope customers will pay. Use confirmed balances and realistic collection assumptions. Keep payroll, tax payments and other cash commitments visible alongside supplier payments.
Record part payments and combined payments carefully
Illustrative example: a supplier has approved bills of £800 and £500. The business pays £1,000 with a remittance allocating £800 to the first bill and £200 to the second. The remaining payable is £300 on the second invoice.
Match the bank payment to those allocations. Recording £1,000 as a new expense would duplicate costs already entered from the invoices. Marking both bills as fully paid would hide the remaining £300.
If a £50 credit note then relates to the second bill, attach and allocate it appropriately, leaving £250 payable. The supplier statement, internal ledger and next payment schedule should tell the same story. All figures here are illustrative and ignore VAT.
Protect supplier details
A request to change bank details deserves independent verification. Contact the supplier using an established number or contact record, rather than relying solely on the message requesting the change. Keep evidence of the check and separate editing supplier details from releasing payment where the team size allows.
Review new suppliers and unusual payments before inclusion in a batch. A familiar logo or an urgent email is not a substitute for checking that the bill relates to a genuine purchase.
Close the loop each month
Reconcile major supplier statements, investigate old debit or credit balances and review bills awaiting approval. Confirm that payments entered near month end reached the bank and were allocated correctly. Escalate recurring missing invoices or approval delays as process problems.
EPOS bookkeeping services can be discussed around supplier ledgers and reconciliations. Where payment timing is creating pressure, connect that work with cash flow support so the schedule reflects the business’s wider commitments.
