What InventoryOS does
InventoryOS helps resellers manage stock, sales and dispatch in one web app.
InventoryOS is a browser-based inventory management application for UK resellers. Users can add products, track stock locations, scan barcodes, record sales, manage expenses, upload receipts, prepare shipping labels and view business reports from one account.
When a user chooses to connect Gmail, InventoryOS only uses Gmail access to find shipping-label emails and label attachments for the Dispatch Centre. This helps users import postage labels into their packing and printing workflow.
Gmail connection is optional. InventoryOS does not use Gmail access for advertising, marketing, selling user data or reading unrelated emails. Users can disconnect Gmail access at any time.
Built around the real workflow
Stop losing time to stock chaos.
InventoryOS connects the jobs that resellers usually manage across several spreadsheets, browser tabs and bits of paper.
“Where did I put it?”
Track every item by box, shelf, rack or your own custom location type.
“Did that actually make money?”
Record sales, refunds and expenses so revenue and profit are not confused.
“Why is printing so awkward?”
Generate product labels and send cropped shipping labels directly to supported thermal printers.
One connected system
Everything you need to run stock properly.
Start with simple inventory tracking, then use the deeper tools as your reselling operation grows.
Inventory
Know exactly what you own and where it is.
Add stock, search instantly, move individual items or entire locations, remove sold stock and process refunds without losing the history.
