Find and file Amazon FBA reimbursement claims for sellers.

In short: an AI-agent-run business you oversee about an hour a week. Tools cost $30–$85/mo, agent setup is intermediate, and our estimate is 30 sellers × $49 = $1,470/mo.

How it makes money: Charge FBA sellers $49/mo to find lost or damaged units and draft reimbursement cases they submit.

Where this came from (Reddit)

FBA sellers lose units in receiving, warehouses and returns, and getting paid back means digging through reports and filing cases before the deadlines pass.

The threads (in our words)

  • A backend engineer with 15 years in logistics, after reading many posts about FBA shipments stuck in receiving and inventory going missing, proposed a $149/month tool that watches shipments through Amazon’s official API, alerts on discrepancies and builds evidence packages for cases.

Reddit blocks automated reads, so we couldn’t record upvote or comment counts. The business below is our own design inspired by these threads.

Who it’s for

Amazon FBA sellers shipping hundreds of units a month.

Adapt it to your industry

  • Start with one niche or customer type, then expand.
  • Ask your first 10 customers what they would pay before you build more.
  • Keep a human check on anything sent in a customer’s name.

Step by step

  1. Connect the seller’s account through Amazon’s official seller tools with read-only reports.
  2. Have the agent compare units shipped, received, returned and reimbursed every week.
  3. Flag each gap with its deadline and the documents that prove it (invoices, tracking, ledger lines).
  4. Draft one clear case per issue; the seller reviews and submits it.
  5. Charge a monthly plan or a share of money recovered through Stripe.
  6. Track case outcomes and refile denials once with better evidence.

What they did

An agent checks shipment, inventory and refund reports for lost, damaged and under-reimbursed units and prepares one evidence-backed case per issue for the seller to submit. We designed this business from real Reddit threads; it is an idea for you to build, not a description of the posters’ businesses.

How it went

Found on Reddit in r/FulfillmentByAmazon (1 thread). Upvote and comment counts weren’t retrievable, so none are shown. On X, 8 posts matched our search for this idea in the 7 days to 2026-10-19.

Worth knowing

Use Amazon’s official data access and case process only; file accurate claims (false claims risk the account); the seller approves every case.
