An item scanned, charged, and fiscalized in seconds - already in the books.
The Challenge
A small fashion boutique in Šibenik runs its entire business in Minimax - articles, prices, stock, and invoices. The counter needed a till as fast as a classic cash register, but without double entry: scan an item, charge it, and have the invoice land in Minimax immediately - fiscalized and printed.
Off-the-shelf POS solutions would have meant another article database to maintain, monthly fees, and software that doesn't talk to the existing bookkeeping. Instead, I built a custom Android app that runs on an ordinary smart phone or tablet at the counter.
The Solution
Butiga POS is built around one rule: Minimax is the single source of truth. Articles, prices, VAT rates, customers, and payment methods are pulled from Minimax, and every invoice is created and fiscalized through it - no retyping, no second set of records to reconcile.
The interface is designed for the cashier, not the accountant: the amount is the largest element on screen, every step has one obvious next tap, and a complete sale - scan, quantity, payment - fits in a couple of seconds.
What I Built
- A sale in a couple of taps - camera barcode scanning or article search, cart, payment by cash or card
- Fiscal invoices through Minimax - the invoice is created in Minimax at the moment of payment and fiscalized immediately
- Receipt printing - a thermal printer at the counter; the receipt comes out as soon as payment is confirmed
- R1 (business) invoices - the business buyer is picked from Minimax and the invoice carries their details
- Refunds and credit notes - returns are issued as credit notes tied to the original invoice, through a clearly marked, protected flow
- Daily Z-report - revenue by payment method and by cashier, ready at the end of the shift
- Floor price protection - cashiers can't discount below a threshold set by the owner; the purchase cost is never shown anywhere
- PIN login and roles - cashier and admin, with automatic screen locking
- Catalog and stock sync - inventory is pulled from Minimax, and every sale decrements it immediately
- Native Android
The Results
- One set of records instead of two - everything sold at the counter is in Minimax immediately; nothing is retyped by hand
- Faster checkout - a complete sale, from scan to printed receipt, takes a few seconds
- Numbers the owner trusts - the daily Z-report matches the bookkeeping because it comes from the same data
