Purchases, sales, transfers and returns for small trading businesses, with a stock ledger that always adds up. Average cost, low-stock alerts, payments and customer invoices on a signed link.
Spreadsheets lose track the first time two people sell the same last item. Stock Manager changes stock in exactly one place, so the numbers always add up.
Every change is one signed line, and stock can never go below zero. The ledger always equals the stock table.
Receiving a purchase recalculates the weighted average cost, and each sale saves the cost at that moment for true profit.
A sale is checked as a whole. If any line is short, nothing is deducted and you are told which product.
One flow with no copying between sheets.
Pick the supplier and warehouse, add lines with cost and tax.
Stock goes up and the average cost is recalculated.
Complete the sale, record payments, never above the amount due.
A signed link or a WhatsApp message in one tap.
Built around the real work of a trading business: buying, storing, selling, getting paid and never selling what you do not have.
SKU, barcode, categories, brands, units, cost, price, tax rate and a low-stock alert level. Services need no stock.
Raise an order, receive it into a warehouse and stock goes up. Average cost is recalculated on receipt.
Draft, complete, pay in parts. Refused whole if any line is short; profit uses the saved cost.
Stock is tracked per warehouse. Move goods in one document, all lines or nothing.
Every change is one signed line and stock never goes below zero. The ledger equals the stock table.
Returns limited to what was sold or received, plus count corrections for damaged or missing goods.
A signed link shows tax, discount, paid and balance, prints cleanly and opens in WhatsApp.
Sales, profit, stock value, low stock, what customers owe you and what you owe suppliers.
Each rule lives in one service and is covered by automated tests, so two people can never sell the same last item.
Seventeen admin screens cover products, people, trading, stock, expenses and settings, with a dashboard that shows what needs attention today.
The customer invoice needs no login, and the admin panel is responsive from phone to wide monitor.
Everyone sees exactly what they need, and nothing they should not.
Sets up settings and logins, deletes drafts and sees every number.
Raises purchases, completes sales, records payments, moves stock.
Opens a private invoice link with tax, paid and balance.
Tracked per purchase with payments and what you still owe.
Two roles, signed invoice links and rate limits on every public page. No public registration and no default passwords.
Staff cannot open Settings or logins, or delete records. Any other role is locked out.
Completed sales, received purchases, transfers and returns are read-only. Only drafts can be deleted.
Invoice links are signed and do not expire. Tampered links are refused.
Stock changes run in transactions with row locks, so two staff cannot sell the same last item.
Demo mode is off by default. When on, one-click logins accept only signed links.
The stock ledger and stock levels are read-only, and products with history cannot be deleted.

One end product per licence, full source, and honest limits so there are no surprises.
The things buyers ask most.
No. Stock changes run in a transaction with a row lock, and a sale is checked as a whole. If any line is short, nothing is deducted.
Receiving a purchase recalculates the weighted average cost. Each sale line saves the cost at that moment, so profit stays correct even when costs change later.
Yes. Stock is tracked per warehouse, and transfers move goods between them in one document, all lines or nothing.
Posted documents are read-only by design. Record a return or an adjustment so the ledger keeps a true history.
