Marketplace claims and reimbursements
Recover marketplace claims without manual portal work
For marketplace-heavy sellers. Fask files and tracks Amazon and Walmart claims for lost FBA inventory, receiving discrepancies, overcharged fees, returns, stranded inventory, and payout mismatches.
Built on Myst
Outcomes teams measure
What marketplace and finance ops teams watch once Fask files reimbursement claims.
Fewer missed FBA and fee claims
Seller Central windows tracked before they close.
Cleaner payout and fee reconciliation
Reimbursements, fees, and returns matched to accounting.
How Fask compares
Reimbursement tools chase claims, but ignore the broader ERP, inventory, and 3PL exceptions.
Reimbursement tools
GETIDA, SellerLocker, Carbon6, Helium 10 Refund Genie
Focused on claims, but less useful for broader ERP, accounting, inventory, and 3PL exception work.
Marketplace suites
ChannelAdvisor, CommerceIQ, Pacvue
Strong for channel management, but claims still require evidence gathering and follow-through.
RPA
UiPath, Automation Anywhere
Portal scripts are fragile and do not reason across payout, inventory, return, and 3PL data.
Spreadsheets
Manual fee audits and claim trackers
Cheap to start, but windows close and evidence goes stale as volume grows.
Keep Seller Central and your channel suite. Run Fask as the detect-file-reconcile layer.
