German beverage retail keeps three things apart that ERPNext treats as one: the price of the drink, the statutory deposit per bottle and crate, and how many containers a customer still holds.
What the app adds:
Deposit lines generated from a per-item container matrix — 12 crates of beer become 240 bottle deposits and 12 crate deposits
A quantity ledger per customer and supplier, modelled on Stock Ledger Entry
Correct VAT: a bottle deposit inherits the tax rate of the drink it belongs to, a pallet is a supply of its own
A separate UI at /pfand for counter sales, barcode intake, documents and reporting — usable without desk access
