Flat software vs a 25% cut
Worked against one figure: $18,430 reimbursed over a year on the Growth plan. Commission rates for recovery services vary; 25% is a common published rate.
| Costback — Growth, $49/mo | 25% commission service | |
|---|---|---|
| What you keep of $18,430 | $18,430 | $13,822 |
| What it costs you in a year | $588 | $4,608 |
| Access to your Seller Central account | None — you upload report exports | Usually full user access or API authorisation |
| Who opens the case | You, in your own account, after reviewing it | The service, in your name |
| Sourcing cost documented per SKU | Effective-dated, invoice attached | Varies; often Amazon's figure is accepted |
| Cost when nothing is found | $49 | $0 |
| Contract | Monthly, cancel in Settings | Often 6–12 months with exit terms |
Costback does not file claims. A commission service that files on your behalf is doing different work — this table is about what it costs you and what it needs from your account, not a claim that the outcome is identical.
When Costback isn’t worth it
If you sell under roughly $150k a year FBA, or you already reconcile reimbursements monthly in a spreadsheet you trust, a flat subscription may cost more than it finds. Run the free estimate first and decide from the number, not from this page.
Is there a free trial?
No. Billing starts the day you subscribe, so we don't call anything a trial. The free calculator is the honest version of a trial: it reads your report and shows you the number before you pay.
What happens if I cancel?
Your subscription ends at the close of the current month. Your cost ledger and claim packages stay exportable for 30 days, and Settings → Data lets you download or delete everything at any time.
Do you charge per claim or per recovered dollar?
Never. The plan price is the whole price, whether Costback finds nothing or finds thousands.
Can I switch plans?
Yes, up or down, from Settings. Changes are prorated on the next invoice; SKU limits apply immediately.
