Counter staff and customer at a point-of-sale tablet — the register MiniBook3 is built for

What is MiniBook3?

Not a browser cloud pretending to be a till — a counter-native register for Linux and Windows, with a clear ladder from Free to Solo to Enterprise.

What is MiniBook3?

MiniBook3 is precision point-of-sale software that lives on your counter PC. It rings sales, tracks stock and shifts, prints receipts, and keeps the shop ledger local — so your livelihood is not rented from a browser tab.

A desktop POS for Linux and Windows — sales, stock, shifts, and receipts on your machine
Offline-first by design: Wi‑Fi drops pause the cloud, not the till
Free forever to start; Solo and Enterprise when the floor needs more
Same product language on both platforms — train once, deploy where the desk is

Retail checkout counter where MiniBook3 belongs

Built for the desks that cannot freeze

Whether you run a boutique, a pharmacy, a grocery aisle, or a multi-station floor, MiniBook3 is for operators who need the register to keep working when the network does not.

Cashiers who stay keyboard-fast through the lunch rush
Owners who want honest Z-reports that match the drawer
Managers who unlock credits, team, and branding when Solo fits
Fleets that need Enterprise connectivity without giving up shop-owned data

Busy service counter that keeps moving offline

Scale & reliability

Built to lead offline POS on load.

MiniBook3 Solo is engineered for category-leading load management, efficiency, and productivity. In our lab, the till kept operating with over one million product SKUs and over twenty million transactions in SQLite — without measured performance reduction. We keep optimizing; the counter stays calm.

1M+

Product SKUs

D73 inventory corpus imported and browsed on Solo

20M+

Transactions in DB

Lab SQLite history — no measured performance regression

Platforms

Linux-MiniBook3 and Windows-MiniBook3 — same contracts

Catalog that stays searchable

Prefix-first browse, keyset pagination, and filter stats that do not block the first paint — even when the aisle holds a million SKUs.

History that stays readable

Returns, shift sessions, and tender drill-downs paginate without loading the whole drawer into memory — tested past twenty million receipt rows.

Figures come from internal MiniBook3 Solo lab runs (D73 one-million-SKU import, commerce-history growth toward 20M+ transactions, and live JSON transaction load). “No measured performance reduction” means core till flows — catalog browse, checkout, shifts, and history pagination — remained responsive on lab hardware. Results depend on your PC, disk speed, catalog shape, and daily volume — we publish evidence, not a universal SLA or third-party ranking.
