Remittance advice

Definition

Remittance advice is a document (increasingly an email or portal note) accompanying a payment, listing the invoice numbers and amounts the payment covers.

In plain terms

Without it, a supplier receiving a lump BACS payment has to guess which invoices you meant to clear. Sending it prevents your account being wrongly flagged overdue.

Why it matters for your company

On the receiving side, chasing remittances speeds your bank reconciliation and stops good customers appearing in arrears. It underpins tidy credit control.

In practice

Picture a small limited company paying several suppliers on the same day via one banking session. Each supplier receives a single BACS credit into their account, but from their side that credit is anonymous — it carries little more than a sort code, account number and a reference field that is often too short to list every invoice being settled.

Sending remittance advice alongside the payment, typically by email or through the supplier's portal, closes that gap. It names the invoices the payment is meant to clear, so the supplier's credit control team can allocate the cash correctly the first time, rather than ringing round to ask what a payment was for. For the paying company, this small habit protects the relationship: suppliers who can match payments quickly are less likely to chase, less likely to place an account on hold, and more likely to extend favourable terms in future.

Common pitfalls

The advice going out with a different reference to the one on the bank payment is the most frequent failure — the supplier's ledger and the company's own records then disagree about which invoices are actually settled, even though the underlying transfer was fine. Splitting one payment across several invoices without an itemised breakdown causes the same confusion in reverse.

Timing matters too: sending the note well after the funds have already landed leaves a window where the supplier's system may flag the account as overdue and trigger an automatic chaser, creating unnecessary friction for a company that has, in fact, already paid. Keeping remittance advice consistent with the payment reference and sent promptly is a low-effort way to keep supplier relationships, and credit control processes generally, running smoothly.
