If your chargebacks are starting to feel like a real number, you have a few options. Let your processor auto-submit a generic rebuttal, which costs nothing and wins occasionally. Pay a success-fee service a percentage of recovered revenue in exchange for processor access. Or hire an enterprise managed service for a retainer that usually starts in the low five figures.
We sit in a fourth position. Flat quarterly pricing, no access to your account, no percentage of your recovery, no submission on your behalf.
Chargebacks arrive on irregular schedules. A merchant might forward five in one week and none in the next three. Monthly pricing punishes the slow weeks and per-letter pricing punishes the busy ones, and neither gives you a predictable cost line to put in front of a finance approver. Quarterly flat pricing matches the rhythm of how disputes actually arrive.
We picked it because it produces the right behavior on both sides. We are not paid more for writing more letters or for fighting cases that should have been refunded. You are not penalized for the quarters when your disputes are heavier than usual. We do not promise win rates either. Issuing banks decide outcomes.
