What's a high-value transaction?

Any card transaction over £10,000 is considered high-value and presents an increased risk of payment disputes such as chargebacks.

Transaction limits

You can accept payments of any value above £1.00 with SumUp after you’re verified. However, high-value transactions present an increased risk and may be stopped for security reasons.

Taking additional precautions improves your ability to process high-value payments securely and helps reduce the risk of chargebacks.

Not verified yet?

A pre-verification limit of £5,000 applies for unverified profiles. Verify your SumUp profile to remove this limit.

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 improve your defence against chargebacks.
