Three steps, in the network's order

  1. 1

    Choose your reason code

    Visa, Mastercard, Amex or PayPal. The code decides every question that follows.

  2. 2

    Answer only what it asks

    No refund-policy question on a code that ignores it. If a field is not asked, this code does not read it.

  3. 3

    Get the pack

    A PDF in the order the network reads it, plus text formatted for Stripe, Shopify Payments or PayPal.

Built for the codes that decide the outcome

Roughly 60 codes across Visa, Mastercard, Amex and PayPal, each with its own evidence rules. See every code and its free checklist.

Visa · 10.4

CE 3.0 checklist included

Other fraud, card-absent

Compelling Evidence 3.0: two prior undisputed transactions from the same merchant, 120 to 365 days older than the dispute date, with at least two of account ID, IP, delivery address and device ID matching across all three transactions, one of them IP or device ID. One submission only.

Mastercard · 4853

Cardholder dispute — the umbrella code for not received, not as described, cancelled recurring or credit not processed.

Amex · C08

Goods or services not received.

PayPal · Item Not Received

Seller Protection: tracking and address match, shipped within 7 days.

Visa · 13.1

Merchandise not received — carrier tracking and delivery confirmation.

What it will not do

Invent a fact

A tracking number, a date, a match it did not see. Missing evidence is flagged in red, not filled in.

State a win rate

No odds, no guarantee, no percentage attached to an outcome. The card network decides, not us.

Charge you to lose

When the evidence says accept the dispute, the pack says so and no payment is offered.

“This prepares your evidence; the card network decides.”

Priced for the size of the problem

One-time payments, no account, no percentage of anything recovered.
