Chargeback & dispute evidence, by payment provider

However your provider words it — dispute, chargeback, claim, or inquiry — the work is the same: organize your genuine records into one clear, submit-ready package. Pick your provider for a focused guide.

Choose your provider

Find your gateway

Each guide is educational and organizational. You always submit your own response; we help you present legitimate records clearly.

Don't see your provider? The same approach applies — start with the free Delivery Dispute Checklist or the guides.

Honest-by-design

Merchant Casefile provides organizational tools and educational resources. It does not provide legal, financial, banking, or payment-processor advice, and does not guarantee dispute outcomes.
