Most of these are not competitors so much as neighbours. They solve a different part of the same problem, and in three of the five cases we would tell you to keep them.
They assemble evidence and fight disputes that have already been filed. We stop disputes from being filed. The overlap is zero, which is why most of our merchants run both and simply send less volume to the representment side each month.
Scoring tools decide whether to accept an order at checkout. That is a different question from what to do forty minutes after a customer calls their bank about an order you already shipped. They also cannot help with friendly fraud, which is where most Shopify disputes come from.
The closest comparison. Resellers pass network alerts into your inbox or a dashboard and stop there. The alert is the easy half. Somebody still has to find the order, decide, and issue the refund inside the window, usually at 3am.
A monthly retainer buys attention, not automation. Agencies are good at the strategic work, descriptor fixes, policy rewrites, acquirer conversations, and poor at the part that has to happen in under an hour, every hour.
Chargebackify started as one. If you have an engineer who can hold network alert contracts, matching logic and refund idempotency in their head, a script gets you most of the way. What it will not get you is direct network participation or somebody else on call when the feed changes shape.
A success fee only works if there is something to prevent. Four situations where the honest answer is no.
Nothing here requires you to cancel a contract. Install in dry-run, watch two weeks of alerts, and compare against the numbers you already have.
Chargeback prevention infrastructure, starting with Shopify. Alerts, refunds and ratio monitoring in one place.
