Capturing consent at checkout: the record that wins subscription chargebacks

Why consent is the foundation

In a Visa 13.2, Mastercard 4841 or Amex C28 dispute, the bank’s first question is whether the customer agreed to be charged repeatedly. Your answer is a record made at the time, tied to this customer.

What to store

Field	Why it matters
Terms version and a copy of that text	Shows exactly what the customer agreed to, even after you update the terms.
Price, billing frequency and first charge date	The details a customer disputes: “I didn’t know it was monthly”.
Timestamp	Ties agreement to a moment before the first charge.
The control used	A checked checkbox or a button labeled with the recurring terms.
IP address and device	Ties the agreement to the same person who later uses the account. It’s also the data Visa’s Compelling Evidence 3.0 matches on.
Confirmation email	A second record the customer received, with the terms restated.

Designing the checkout so consent is clear

Show the recurring price and frequency next to the button, not only in linked terms.
For a trial, show the date it converts and the price after.
Use an unambiguous control, such as a checkbox that must be ticked or a button that says what it does.
Send a confirmation email that repeats the terms and how to cancel.

Keep it findable

Attach the consent record to the order or subscription so it can be pulled in minutes. Storing it in a log nobody can search means you can’t use it. See where your evidence lives.

Questions

What counts as proof of consent for a subscription?

A record made at checkout showing the terms version, price and frequency shown, a timestamp and the control the customer used, tied to this customer.

Are my website’s terms enough?

No. The bank wants proof this customer agreed, not that terms exist.

Why store IP and device at checkout?

It ties the agreement to the person who uses the account, and it’s the data Visa’s Compelling Evidence 3.0 matches on.
