How to choose an offline-first POS

01What “offline-first” must mean

Offline-first is not a marketing badge for “works in a browser with a cache.” It means the sale, stock adjustment, and shift total are written on the merchant PC first. Connected features — licence checks, fleet sync, cloud backup — may pause softly when the network is gone; they must not freeze a ticket already on the counter.

Ask every vendor: where does the ledger live, and what happens mid-sale when Wi‑Fi dies? If the answer is “wait for the cloud,” that is a rented till — not a register you own.

02Buyer checklist for shop owners

Use this list before you sign anything. MiniBook3 is built so each answer is plain on Pricing, Features, and Downloads.

• Local ledger on Linux or Windows — not only a SaaS tab
• Clear Free / paid package ladder with published capacity limits
• Shifts and Z-reports that match the live drawer
• Printer and cash-drawer path that staff can test before rush hour
• Updates that refuse to wipe a shared install parent
• Evidence for large catalogs and long history — not vague “unlimited” claims

03Where MiniBook3 fits

Offline-first POS for Linux and Windows. Lab-tested on Solo with 1M+ product SKUs and 20M+ transactions — no measured performance reduction. Free forever covers a real register with honest caps. Solo unlocks credits, team, exports, and branding when the floor grows. Enterprise adds fleet, portal, and recovery — licensed per PoS node.

Linux-MiniBook3 and Windows-MiniBook3 share one product language: activation, shifts, catalog, and packages. Packaging and printers differ by OS; cashiers train once.

04When a cloud POS is still fine

If every counter has rock-solid internet, you sell only online, and you accept a browser as the till — a cloud POS can be enough. The moment the floor cannot afford a frozen cart, offline-first stops being optional.
