ShopSwarm

Small resellers operating across marketplaces can struggle to reconcile a physical item with listings, sales, fulfillment, receipts and payouts. The supplied research confirms three multi-channel inventory or cross-listing competitors. It found no compared product combining receipt-to-item linking with a reseller tax export, but the comparison is limited and does not validate buyer demand.

ShopSwarm would establish an item ledger with an owner-selected source of truth. Each receipt image would produce extracted purchase assertions for human correction and allocation. Marketplace adapters would import authorized listings, orders, fees, returns and payout events where an approved interface or export exists. The system would preserve platform observation, internal state, proposed inventory change, provider acknowledgment, destination readback and reconciliation separately.

Several named marketplaces have no public interface, restricted access or limited private interfaces. The product must not scrape, automate a browser or bypass controls merely to claim broad channel coverage. Terms, account approval and reliable data access are pre-build gates per channel. Without a permitted integration, the honest fallback is a user-imported file or manual record with its source labeled.

A receipt match is not proof of tax basis, and estimated profit is not settled income. Purchase allocation, shipping, marketplace fees, refunds, reserves, chargebacks, sales tax, currency and payout timing must remain separate. A Schedule C-oriented export is a draft dataset for accountant review, not a filed return, tax advice or agency acceptance. The buyer hypothesis is a small reseller or flipper, but role, volume, budget, current process and accountant involvement need validation.

A small multi-marketplace reseller or operator who owns the inventory records and can authorize each marketplace account, with an accountant reviewing tax treatment.
