Always-on marketplace ops

The AI agent that watches, files, and reports on every marketplace account.

Claimpost monitors every listing across Amazon, Shopify, and Walmart 24/7 — buy-box losses, suppressions, IP complaints, hijackers, competitor price moves — and files reinstatement cases or repricing responses the moment something breaks. Each morning, a P&L-impact report lands in finance's inbox.

How it works

Three jobs the agent never sleeps through.

Claimpost replaces a stack of monthly alerts, repricers, and profit dashboards with one always-on agent that watches, acts, and reports in the same loop.

01 · WATCH
Polls every listing, every minute

Watches every listing across Amazon, Shopify, and Walmart — 24/7.

Buy-box losses, listing suppressions, IP complaints, hijacker attachers, competitor price moves, OOS alerts, search-rank drops. The moment an event fires, the agent classifies it and decides whether to act.

02 · ACT

Files reinstatement, reprices, escalates — in minutes.

Drafts and files reinstatement cases through Amazon SP-API, reprices to defend the buy-box, or escalates an IP complaint while the incident is still hot.

IP · storefront-3escalated
03 · REPORT

Emails a daily P&L-impact report. Every event, mapped to dollars.

At 7am local, finance gets a one-page report — every alert, every action, every dollar saved or lost. No more waiting on delayed accounting ledgers to find out what a hijacker cost you last week.

Coverage

One workspace. Three marketplaces. No copy-paste ops.

Where SellerSonar watches only Amazon and GeekSeller only Walmart, Claimpost cross-stitches incidents the moment they cross a channel boundary — and maps them to a single P&L number at the end of the day.

The morning report

Finance stops waiting on the ledger.

Yesterday's events, today. Every alert mapped to a P&L delta — saved, lost, recovered — so finance knows by 7am what the business actually looked like in the last 24 hours.

  • Per-event dollar attribution, not vague summaries.
  • One inbox line for the team, a full appendix for finance.
  • Tunable — pipe it into your warehouse, your BI tool, or just email.

Why Claimpost

Built for the seller who is tired of stitching tools together.

01

Three channels, one workspace.

SellerSonar watches Amazon. GeekSeller watches Walmart. Claimpost stitches incidents the moment they cross a channel boundary — and attributes the dollar impact in the morning report.

02

Files for you, not just alerts you.

Repricers tell you the buy-box is gone. Reinstatement tools draft the appeal for you to review. Claimpost does the drafting AND filing — escalation included when the appeal stalls.

03

One SKU instead of a stack of subs.

Repricer + monitor + profit dashboard + reinstatement tool — typically $300–$700/mo combined. Claimpost bundles watch, act, and report into one mid-market price.

Pricing

One SKU. Always on.

Bundling watch, act, and report lets us price mid-market sellers under the stack they would otherwise assemble. Quotes scale with channel count, listing volume, and event floor — get in touch and we'll send you a one-line number for your business.

Bundled in

  • ★ 24/7 listing monitoring (Amazon, Shopify, Walmart)
  • ★ Reinstatement auto-filing via SP-API
  • ★ Agentic repricing to defend the buy-box
  • ★ IP complaint escalation & hijacker reports
  • ★ Daily P&L-impact report

Or compare the three plans at /pricing.

Pricing

One-line quote. No comp tiers.

We price against a stack you would otherwise replace — typically $300–$700/mo & up. Bring your current line-up and we'll show the delta.
