# Remittance advice

A **remittance advice** is a short note from the payer that says what a payment is for — usually a list of invoice numbers and the amount applied to each — so the receiver can tie the incoming money to the right invoices.

## How it works

- A customer pays a lump sum covering several invoices.
- The remittance advice breaks that sum down: invoice 1041 in full, 1042 part-paid, a credit note deducted.
- The receiver uses it to apply each portion to the correct open item.

Without it, a single payment is just an amount with no instructions — you can see the money arrived, but not which bills it clears.

## Why it matters

Remittance advice is the difference between a five-minute match and an afternoon of detective work. When a payer settles ten invoices with one transfer and no note, someone has to reverse-engineer the split — and a mismatch of even a few pounds leaves the whole payment stuck. It's a small document that decides how painful [cash application](/glossary/cash-application/) is.

## How Fynex does it

Because Fynex issues the invoices and collects the payments in one place, it already knows what each payment should clear — so remittances reconcile back to the books as journal entries instead of arriving as an [unmatched transaction](/glossary/unmatched-transaction/) to untangle.
