Accept high-value payments securely

Keeping evidence of payments' validity is essential to defend against accusations of fraud. If applicable, we may request some documentation verifying high-value payments you receive:

  • A signed copy of the payment invoice

  • A signed copy of the contract with your customer

  • A sign copy of the customer declaration form available below

  • Proof of delivery

We may also request other relevant documentation, including your customer’s contact details. For this reason, it’s important to keep records of high-value transactions.

What's the customer declaration form?

The customer declaration form allows you to document the validity of a high-value transaction. By getting your customer to complete it, you reduce the risk of a successful chargeback being brought against you.
