Retailer OS keeps the inventory itself, not a copy of it. Sales, receipts, transfers and counts all write to one ledger, so on-hand is current everywhere.

Retail inventory visibility is knowing how much of each item you have at each location, what is on order, and what is moving between sites. Retailer OS is the inventory system of record: every item has a per-location ledger, and each sale, receipt, transfer and adjustment leaves a movement row, so the numbers you see are the numbers the register sells from.
On-hand for each item at each location, with a movement row for every sale, receipt, transfer and adjustment.
Order from vendors, receive against the PO, and track cost.
Count by location with system, counted and variance side by side, and move stock through draft, in-transit and received transfers.
Set reorder points and see which items have dropped below them. AI reorder suggestions need an AI plan (from $19.99/month).
Bring items in by CSV or from Shopify, with variants, units of measure and barcodes.
Choose the on-hand level at which each item should be reordered.
Every receipt, sale and transfer updates the ledger at that location.
Run stock counts and review the variance in units and cost.
Counts, receipts and transfers in one ledger instead of three spreadsheets.
Current on-hand for their store, and reorder alerts before shelves run empty.
Inventory valuation and dead stock reports built on the same ledger.
