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.
On Pro and Business, your workspace has its own shipping-label email address. Forward label attachments to it to import, detect the carrier and crop labels in the Dispatch Centre. You can also upload labels manually.
Email import shows its progress, supports reimporting previous label emails and helps prevent duplicate labels. It does not need access to your Gmail mailbox.
Forward labels from any email provider. Keep your workspace address private and use a label-only forwarding rule.
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.
Tools for your daily workflow
From your first item to a shared stockroom.
Each paid plan adds tools to the plans below it. Reorder email reminders are a separate optional £1.99/month add-on for Pro and Business.

Manufacturing tools on Business
A clear record of what you use and what you make.
Designed for small-batch makers who need practical stock and production tools alongside their everyday sales workflow.
Use the units your work needs.
Track raw materials and packaging separately from whole-item stock. Use each, grams, kilograms, litres, millilitres, metres, centimetres or millimetres, including decimal quantities.
- Receive batches into named storage areas
- Record material batch numbers and expiry dates
- Adjust or relocate remaining quantities with a recorded reason
Define what makes one product.
Create a bill of materials linking a finished product to its components and their quantities per item. Reuse existing products and barcodes or create a new finished item.
- Convert units within the same measurement type
- Link equipment usage per batch or per item
- Edit recipes while keeping completed-run history
Plan several recipes. Order shared ingredients once.
Choose your recipes and finished quantities to see individual requirements and a consolidated ingredient list. Check eligible stock, combine pending material plans and send the shortages to Reordering.
- Each, grams, litres and metres retain their correct units
- Shared ingredients are grouped across recipes
- Supplier links and optional contact details
- Mark materials ordered and receive partial or complete batches
- Optional daily recipe email summary: 5pm UK time by default, or your chosen time
Recipe reorder emails require the optional £1.99/month email add-on. Calculations do not reserve materials or complete production.
Make a batch. Update both sides.
Preview the exact material batches, quantities and storage areas needed. When you confirm production is finished, components are deducted and finished stock is added in one operation.
- Earliest eligible expiry used first
- Insufficient, held, recalled or expired materials blocked
- Finished batch, expiry and destination recorded
Follow a batch through your workflow.
See which material batches made each finished batch, where its remaining stock is located and its recorded movements or dispatch history.
- Hold or recall batches
- Source-material holds and recalls block affected finished batches
- Confirm batch numbers when picking tracked stock
- Existing opening stock is clearly marked as origin unknown
Know when to clean or replace.
Set a lifespan such as 30 uses and a cleaning interval such as every 10 operating hours. Log real use manually or record planned recipe usage when completing production.
- Remaining uses and operating hours
- Cleaning and replacement due warnings
- Separate maintenance and lifespan counters
- History retained when counters restart
Set the deadline and get on with work.
Start “Clean in 10 hours” or “Products ready in 10 hours” from the app. Deadlines stay saved while you are logged out, with optional emails to your verified account.
- Minute, hour and day durations
- Live countdowns and due reminders
- Acknowledge or cancel timers
- No automatic stock change or cleaning confirmation
Closing the website does not stop a timer. Reminders resume after a temporary service outage. Elapsed timer time is separate from logged operating hours.
Your first production batch
Receive. Prepare. Make. Dispatch.
Enable your workspace
On Business, an owner or admin turns on Manufacturing mode in Settings. Pick the inventory you want to work in.
Receive your materials
Enter material batches, quantities, storage areas and optional expiry dates. Create your finished product and its recipe.
Preview and complete
Review the exact source batches, then confirm once the products are finished. Start a timer if they need curing or preparation time.
Use your normal stock tools
Find, move, label and dispatch finished products from the same stock system. Their batch history follows the recorded stock movements.
Everything else your small business needs.
Business also includes shared team inventory, roles and permissions, unlimited active stock, multiple inventories, sales and expense records, receipt uploads, barcode print jobs, shipping-label cropping, mobile sharing, QZ printing, a workspace label email address and reorder rules.
Optional reorder email reminders are £1.99/month. Manufacturing timer emails are included with Business and do not require that add-on.

InventoryOS is independent inventory and operations software. You can use it alongside Vinted, eBay, Facebook Marketplace, Amazon returns, car-boot sales and other channels.

InventoryOS imports and crops supported labels into the Dispatch Centre without connecting to or reading your mailbox. Manual uploads remain available on Starter and above.

Yes. The main stock workflows are designed for mobile browsers as well as desktop. Direct printer setup is currently focused on Windows computers.
