Recover

Most reimbursement tools catch a slice. This finds the rest.

Fulfillment errors compound across a large catalog, and most recovery solutions only cover part of what's actually claimable.

Margin Pro by Threecolts gives you one connected system, with every claim type tracked start to finish.

  • Full claim-taxonomy coverageLost inventory, warehouse damage, underpaid claims, and phantom shipping fees — every reimbursement category, not just the obvious ones.
  • Proactive detection before windows closeSurfaces what should be filed before the deadline, instead of only catching it after a manual audit.
  • Tracked to payment, not just to filingEvery claim followed through to actual payment, with denied claims re-filed or appealed automatically.

Frequently asked questions

Lost or damaged inventory, warehouse miscounts, underpaid or low-balled reimbursements, and canceled or unused shipping labels — across both Amazon FBA and Walmart WFS.
Amazon's shift to manufacturing-cost-based reimbursement for pre-sale lost or damaged inventory is a real, current policy change, and it does affect how much certain claims are worth. Margin Pro tracks marketplace policy changes on an ongoing basis and adjusts how claims are identified and filed as rules change, rather than working from a static playbook.
Sellers who dedicate real time to reimbursements still typically recover well under half of what's owed — the rest stays buried across receiving scans, weight/size fee errors, and disposal events that don't surface in standard reports. Margin Pro runs continuous, automated audits that catch what periodic manual review misses.
Amazon's overall claim window runs up to 18 months, but individual claims often carry tighter cost-documentation deadlines within that window. Walmart WFS is considerably tighter — claims must typically be investigated within 10 to 50 days of delivery confirmation.
Both. Margin Pro covers Amazon FBA and Walmart WFS reimbursements, including WFS-specific claim types like material transfer request losses.
Denied claims are re-filed or appealed rather than dropped — Amazon allows re-evaluation, and Walmart allows one appeal within 30 days of denial.
Setup is a read-only connection, and no operational changes are required on your end. Claims are filed using compliant, evidence-backed documentation rather than disputing everything to see what lands, which is what puts account standing at risk.
Yes. Your existing catalog can reach any of eight supported marketplaces without being rebuilt for each one — UniCon syncs it once and keeps every channel in step.
Amazon, Walmart, Shopify, TikTok Shop, Shein, Temu, eBay, and Target+ — any of them can act as your source or your destination.
No. Channel expansion is a managed motion, not a hiring plan.
Rebag put 25,000 unique luxury items live on Walmart Marketplace without rebuilding its catalog. Timelines scale with catalog size and channel complexity.
Both, through one partner — one relationship and one contract instead of managing recovery and expansion through separate vendors.
A guided, read-only connection to Seller Central and/or WFS, typically set up in about 15 minutes. No write access or changes to how your team already operates.
Margin Pro is performance-based — no upfront fee, no subscription. You pay a pre-agreed share of what's actually recovered.
Setup is a single guided session, and Margin Pro runs in the background from there — your existing workflows and team processes stay exactly as they are.
