Inventory management software for eBay sellers

The key facts

• eBay manages its own marketplace quantities — listings, sold counts, thresholds — and does it competently for a single channel.
• The gap: stock that exists elsewhere (shelf, warehouse, other channels) needs one shared record; eBay quantities are a copy, not the source.
• BSimple runs the shared record and imports orders from connected channels — the honest boundary: marketplace integrations are evaluated per channel, and Shopify is the built-in import today.
• From $180/month (AUD), free to trial; invoicing handoff to Xero or MYOB.
• Context: the full inventory system holds the wider system, this page one stop in it.

What eBay handles — and what it cannot see

For a seller whose entire stock is listed and fulfilled through eBay, eBay's own inventory is enough: quantities per listing, sold counts, out-of-stock control. The record and the channel are the same thing, which is the simplest possible arrangement.

The gap opens with the first second channel — a warehouse shelf that holds unlisted stock, a Shopify store, a wholesale order, a counter sale. eBay cannot see those movements, so its quantities are a copy that only stays right if nothing else touches the stock. Sellers know the failure: the marketplace sells an item the shelf already promised to someone else. The fix is not more eBay settings; it is a record that owns the truth and lets channels consume from it. The ecommerce pattern covers this division of labour.

How BSimple fits a marketplace seller — honestly

We build BSimple, so weigh that. BSimple holds the shared record: live quantities across locations, purchasing from reorder levels, counts from any phone browser, and orders flowing through pick and pack to invoicing with the Xero or MYOB handoff — from $180/month (AUD). For order import, the built-in channel today is Shopify by webhook — store orders arrive into the same flow as every other order, with delivery slips, pick/pack, approval and stock deduction. For eBay specifically, we do not claim a native eBay integration: connecting a marketplace happens through its export/import paths or a listed integration partner, and we would rather say that plainly than imply a sync we do not ship.

The honest test for an eBay seller is therefore the record, not the sync: import your SKU list, receive and count real stock, and see whether one trusted record beats three stale copies — the trial answers that in an afternoon. The Shopify connection shows how the imported-channel pattern works in the product today, and the free-EBay comparison covers the free-tool landscape sellers usually try first.
