Supporting Documents & Invoice Guidelines

Last updated: June 10, 2026

Certain rails and currencies require supporting documents for a payment to be processed. Providing proper documentation reduces the chance of a Request For Information (RFI), payment failure, or refund. Please follow the guidance below.

Accepted supporting documents by payment reason

Payment reason	Supporting document(s)
CONSULTING_FEES	Invoice, contract, or agreement between parties
DOWN_PAYMENTS_FOR_REAL_ESTATE	Purchase contract, mortgage contract
EMPLOYEE_SALARIES_OR_WAGES	Employment contract, pay-slip
EXPENSES_REIMBURSEMENT	Receipts, expense reports
PURCHASE_OF_GOODS	Invoice, contract, or agreement between parties
PURCHASE_OF_SERVICES	Invoice, contract, or agreement between parties
REMITTANCE	Bank statement, remittance confirmation letter
RENT	Rental agreement
ROYALTIES	Invoice, royalty contracts

For a remittance confirmation letter, please include the main purpose of the remittance (e.g. family support), the name of the sender and beneficiary, the amount, and the date.

Invoice best practices

To ensure consistent and reliable deliverability of payments, follow these best practices when submitting invoices as supporting documents. Failure to follow them may lead to RFIs, payment failure, or refunds.

Invoices must clearly identify the buyer (sender) and seller (recipient) of the goods or services purchased. Include the full name and address of both buyer and seller, and the seller name should match the name on the recipient bank account (i.e. the external account holder name).
The invoice must be dated.
The invoice must contain the description and quantity of goods / services offered.
The invoice must be in the same amount and currency as the payment amount / currency.
The invoice should be signed and/or stamped by the relevant party.
The invoice should reasonably correspond to the payment reason.
If the recipient account number is included on the invoice, it should match the account number used in the payment.

Responding to RFIs

Certain payments may trigger a Request For Information (RFI), where our compliance team or a banking partner requires more information about a payment. An RFI can be raised while a payment is processing or even after it has completed. RFIs are sent to your team, and you can then share them with your customer as needed. Responding as quickly as possible is critical — failure to answer an RFI may lead to the beneficiary being blocked, the payment being refunded, or further compliance action.
