The problem

Marketplaces quietly keep money that belongs to you

Across thousands of orders, small errors add up. Most sellers never see them, because finding them means reconciling every fee, return and inventory movement by hand.

Lost & damaged inventory

Units lost in warehouses or damaged in handling that never get reimbursed.

Fee overcharges

Wrong size tiers and weights inflate fulfillment and referral fees on every order.

Refunds without returns

Customers refunded but the item never comes back, and nobody claims it.

Payout gaps

Settlements that don't add up to what you sold, hidden in thousands of lines.

Money recovery

Every dollar you're owed, found and ready to claim

SellerSyd continuously checks your account for reimbursable losses and overcharges, and prepares each claim with the evidence marketplaces ask for.

  • Lost, damaged and stranded inventory
  • Fulfillment and referral fee overcharges
  • Refunds where the item never came back
  • Track every claim from filed to paid

FAQ

Questions, answered

Which marketplaces does SellerSyd support?
Amazon is supported today. Shopify and Walmart are next, followed by eBay and Etsy. One SellerSyd account will cover all of your channels.
Is SellerSyd for sellers or for agencies?
Both. Sellers and brands connect their own stores. Agencies manage many client accounts from one login, with team permissions and their own branding.
How does SellerSyd access my seller account?
Through the marketplace's official authorization flow. You approve access in Seller Central, and you can revoke it at any time. We never see or store your marketplace password.
How is money recovery different from doing it myself?
SellerSyd cross-checks every order, fee, return and inventory movement continuously, and prepares the claim with the evidence attached. Most sellers simply don't have time to do that by hand across thousands of transactions.
Is my data secure?
Yes. Connections are encrypted, marketplace tokens are encrypted at rest, every account's data is isolated, and two-factor sign-in is available for every user. See our security page.
How much does it cost?
You can start free. Paid plans add more accounts, team members and features. See pricing.
