Fulfillment and delivery

Proof of delivery

Tracking, signatures, photos, and the full delivery address.

Tracking says delivered

Customer filed non-receipt after a delivered scan.

Digital delivery

Access logs, IPs, downloads, license keys.

Service completion

Work orders, check-ins, and signed completion.

Authorization, account, and terms

AVS, CVV, and 3-D Secure

What those checks show, and what they never show.

IP, device, and account history

Prior orders, logins, and device signals.

Customer communications

Excerpts that corroborate; threads that hide the point.

Invoices and receipts

Amounts, SKUs, and what a receipt cannot prove.

Refund and return policy

Only the section shown before purchase, and only for the right reason.

Cancellation and recurring authorization

Terms accepted, cancel request, charge date.

How the files are packaged

Issuers review a high volume of responses. Shopify and Stripe both tell merchants to lead with the direct proof and keep files short. See exhibit index and what not to submit.
