Inventory
Stock levels follow on their own
Book goods in, write a delivery note, issue an invoice. Stock follows every step without you maintaining a second spreadsheet.

Goods in and out in one place
Every movement is documented: what, when, how much, from whom. Sell an item on an invoice and stock drops automatically. No reconciling between invoicing and a stock list.
Delivery notes and shipping
An order becomes a delivery note, a delivery note becomes an invoice. Shipping method and tracking number stay with the record, so queries take seconds.
Storage locations and labels
Items sit in named locations. Barcode labels print straight from Buchungsfluss, so stocktaking is not guesswork.
Suppliers and purchase prices
Each item carries a supplier and a purchase price. That shows your margin without recalculating it every time.
What inventory is not built for
- No batch or serial number tracking.
- No connection to a shipping system for generating labels.
- No multi-warehouse operation with transfer documents between sites.
Which plan
Inventory, labels, sales and rental are included in the Business plan at 19 € a month. Delivery notes are alternatively available as an add-on from 3.90 € a month.
