## FAQ

### How should I state the payment reference on the original invoice?
Use a clear instruction, for example “Please quote RE-2026-104 as the payment reference”. Check the recognized value in the review field Remittance information (BT-83); do not assume an invoice or order number will automatically become the payment reference. This is an illustrative example, not a default value. Clear wording helps recognition but does not guarantee it. BT-83 does not initiate a payment or guarantee automatic processing by the recipient.
