Why do I lose chargebacks even with signed proof of delivery?
Small businesses upload signed delivery slips, invoices and emails, then get an automated email saying they lost the dispute plus a fee, because the customer's bank decides and the processor will not intervene.
Who has it: Small B2B and service businesses taking card payments of USD 500 and up, and ecommerce stores with high value orders.

A dispute coach for small non ecommerce businesses: map the reason code to the exact evidence the card network rules require, build the response in the issuer's format, and set up prevention (clear descriptors, signed terms at checkout, 3D Secure on big tickets) before the next one.
Tools that solve this
3 named so far, and where each one stops.
- Chargeback services (Chargeflow, Chargebacks911, Justt)
Write dispute responses, mostly for ecommerce stores on Shopify and Stripe.
- Processor dispute tools (Stripe, Square)
Let you upload evidence, but give little guidance on what each reason code needs.
- Bank transfer only for large orders
Avoids disputes, at the cost of losing card customers.
How you might build it
- 01Card network reason code rules engine
- 02Processor dispute APIs (Stripe, Square, PayPal)
- 03Evidence packet generation
- 04Checkout terms capture
- 05Win rate analytics
