Stock and sales software
Stock and sales without notebooks or an old program
LagerOS is software for shops, wholesalers and importers in Serbia: what arrived, what is in stock, what was sold and who owes you. Scan the barcode with a reader or the phone camera and the stock keeps itself.

Why businesses switch to LagerOS
The old program runs on one computer, stock is counted by hand and customer debts live in a notebook. In LagerOS items, receiving, sales and debts are in one place, on every computer and phone in the business, and every change is recorded.
What the stock software does
Items with barcodes, photos and three prices
An item can have several barcodes, packs (a box of 12), a category and photos. Three selling prices, for example dealer, retail and bulk, with a price history.
Import your item list and opening stock from Excel, and on the Pro plan from a photo or PDF of a supplier's price list.

Receiving goods by scanning
Receive a delivery with the scanner: each scan adds one piece, with the cost price and supplier. From a purchase order you see at once what arrived and what is missing.
Selling prices can be calculated from the margin you set, and a price change log keeps every change.
Checkout: scan and get paid
Sell by scanning, with a discount per line or on the whole receipt, a regular customer's discount and promotions such as 3 + 1 or a free gift. Print the receipt or send it to the customer as a PDF, by Viber or WhatsApp.
Stock goes down by itself, from the oldest delivery first, so you also know the profit per receipt and per item.

End-of-day count
At the end of the day each seller sees how much should be in the till, enters what they counted and sees any surplus or shortage at once.

Customers and debts
Each customer's account: what they bought on credit, what they paid and how much they owe. The home page shows who owes you the most and who is late.

More for stock and sales
Several warehouses and shops
Stock per warehouse, transfers from the warehouse to a shop and selling from the chosen shop.
Stocktaking and write-offs
Stocktaking by scanning shows the difference between the app and the shelf. Damaged goods are written off with a reason.
Purchase orders to suppliers
“Order what is missing” suggests items below the minimum quantity, and the order goes to the supplier as a PDF.
Orders via a link
Customers and resellers order from their phone through your link, and an order becomes a receipt in one click.
Barcode labels
For an item without a barcode the app creates an internal code, and you print labels with the price on a roll or A4.
Reports and profit
Sales per day, month, item and seller, with profit by cost price. Export to PDF and Excel.
Selling goods from €15 a month
The first month is free, with no limit on items or receipts. The Pro plan has no limit on users.
Do you also issue invoices?
LagerOS also handles invoices, pro forma invoices, delivery notes and the KPO book. An invoice from items reduces stock, and a checkout receipt can become an invoice. See the invoicing and KPO software.
