What remittance advice is for
Updated August 2026 · 6 minute read
A remittance advice is a note you send a supplier saying which invoices a payment covers . A bank transfer arrives as one amount with no explanation, so without the note the supplier has to guess which invoices you paid.
The problem it solves
A supplier has sent you 4 invoices. You pay 3 of them in one transfer, netting off a credit note. What lands in the supplier's bank account is one amount and a payment reference of maybe 18 characters.
From the supplier's side that is a puzzle. Somebody in their accounts team now has to work out which invoices the figure corresponds to, whether the shortfall is the credit note or a dispute, and whether to chase you. If they guess wrong, they apply the cash to the wrong invoices and chase you for one you have already paid.
The remittance advice is the answer sent alongside the payment. It lists the invoice numbers, the amount allocated to each, any deductions, and the total. The supplier's cash allocation becomes a matching exercise instead of an investigation, which is why suppliers ask for one and why chasing letters often start by saying no remittance was received.
What a remittance advice contains
There is no legal format and no standard layout. These are the fields that make one usable, and a remittance missing the first two is not doing its job.
- The invoice numbers
- The supplier's own references, exactly as printed on their invoices. Your internal purchase order number is useful as well and is not a substitute: the supplier allocates against their numbering, not yours.
- The amount allocated to each invoice
- Line by line, not only a total. A single total tells the supplier what arrived and not how to apply it, which is the whole point of the document.
- Deductions, and why
- Credit notes, agreed discounts, withholding, and short payments each named with the reason. An unexplained deduction is the single most common cause of a supplier query.
- The payment total, date, and method
- The figure that will appear on their bank statement, the date it was sent, and how. This is what lets them match the note to the money.
- Who to ask
- A name or an accounts payable address. A remittance with no route back turns any discrepancy into a phone call to whoever answers.
What it is not
Four documents get confused with each other because all four accompany a payment somewhere in its life. They are sent by different parties at different moments.
| Document | Sent by | Says |
|---|---|---|
| Remittance advice | The payer, when paying | Here is what I am paying and which invoices it settles |
| Invoice | The supplier, before payment | Here is what you owe me |
| Receipt | The supplier, after payment | I have received your money |
| Purchase order | The buyer, before delivery | Here is what I am ordering |
| Statement of account | The supplier, periodically | Here is everything outstanding between us |
The practical difference: a receipt is proof for the payer, a remittance advice is an instruction for the supplier. They travel in opposite directions.
Is it required
No. Sending a remittance advice is a courtesy in most jurisdictions and most contracts, not a legal obligation. Suppliers ask for one because it saves them work, and larger suppliers increasingly make it a condition of their payment terms.
The exception worth knowing is payroll and government schemes, where a document by the same name can carry a statutory meaning. In the United States, healthcare payers issue a remittance advice under the standard called 835, and that one is a formal electronic document with a defined structure rather than a courtesy note. If you have been sent an 835 file, it is a different thing from the note this article describes.
In practice the reason to send one is self-interested. A supplier who cannot allocate your payment will chase you for invoices you have already settled, and the time spent answering that costs more than the note would have.
How to send one that is actually useful
A remittance advice can be a PDF or an email. Include the payment date, amount, invoice references, and payer details.
-
Send it when you send the payment, not after
A remittance that arrives a week later has already cost the supplier the work it was meant to save. Same day is the standard.
-
Use the supplier's invoice numbers
Copy them exactly, including any prefix. A transposed digit puts the note back into the guessing category it was meant to remove.
-
Explain every difference between the invoice total and what you paid
Name the credit note, the discount, or the disputed line. An unexplained short payment reads as an error and generates a query.
-
Send it to accounts, not to your sales contact
Your day-to-day contact is rarely the person allocating cash. Most suppliers publish a remittance or accounts address for this.
The same problem, from the receiving end
If you are on the supplier side, the remittance advice is only half a solution. You still have to match the note to the payment on your bank statement, and the payment reference on the statement rarely resembles the payer's name in a helpful way.
That matching is the work: a payment arrives on the statement, a remittance advice explains it, and a set of invoices has to be marked as settled. When the remittance never arrives, the only evidence available is the statement line and the amount, and allocation becomes arithmetic against open invoices.
LedgerBox does not support remittance advice. It supports invoices and bank statements. Use their extracted rows to match a payment.
Questions people ask
What is a remittance advice?
A note sent by a payer to a supplier saying which invoices a payment covers, and how much of the payment applies to each. It exists because a bank transfer arrives as a single unexplained amount, and without the note the supplier has to guess how to allocate it.
Is a remittance advice the same as a receipt?
No, and they travel in opposite directions. A remittance advice goes from the payer to the supplier when the payment is sent, saying what is being paid. A receipt goes from the supplier to the payer afterwards, confirming the money arrived.
Is sending a remittance advice a legal requirement?
Generally no. It is a courtesy that many suppliers now require under their payment terms. The exception is documents carrying the same name under formal schemes, such as the 835 remittance advice used by healthcare payers in the United States, which has a defined electronic structure.
What should a remittance advice include?
The supplier's invoice numbers, the amount allocated to each, any deductions with the reason for them, the payment total, the date, the payment method, and a contact for queries. The per-invoice allocation is the part that matters; a total alone does not help the supplier.
