Legacy tools collapse catalog titles with warehouse counts and cause sync drift. eListSync isolates physical truth from channel presentation.
Physical Inventory
One warehouse truth per SKU. Stock changes here are the source peers reconcile against — not channel-local guesses.
Active Listings
Channel-side titles, prices, and presentation stay separate. Matching SKUs link back to the same inventory record.
Sales channels
Connect Shopify, eBay, WooCommerce, and more. Day-1: authorize the store with your most accurate stock first.
Day-1 in three calm steps
Match how serious multi-channel operators actually set up — not a paste-URL first flow.
- 01
Connect accurate-stock channel
Authorize the store whose quantities you trust most. That import seeds Inventory.
- 02
Wait for import
Listings arrive and SKUs auto-link into Inventory. Do not add peers until this finishes.
- 03
Add peer channels
Connect secondary marketplaces. Verified stock synchronizes so two channels cannot sell the same unit twice.
Publisher and URL / document import stay available when you create listings — they are secondary to keeping Inventory accurate across channels.
FAQ
Practical answers for ops, engineering, and marketplace compliance teams evaluating eListSync.
Inventory updates and order webhooks reconcile stock quickly. Atomic locks decrement quantity once; duplicate events are dropped with idempotency keys. Unhealthy channels trip a circuit breaker instead of silently drifting.

Connect the sales channel with your most accurate stock, wait for import into Inventory, then add peer channels. Publisher / URL paste is optional when you create listings — not the Day-1 path. See /docs/quickstart.

No. eListSync is a browser web app. An optional browser extension can capture a page for ingest. There is no desktop installer.
