Switch from your old POS without downtime.
ShopFlash is a Chrome-first POS for small stores still running legacy software. Fast checkout, offline reliability, painless migration — on the computers you already own.
Legacy POS vs. ShopFlash
Same store. Same staff. Same hardware. Different Tuesday.

- Outdated Windows softwareLocked into vendors that stopped shipping updates years ago.
- Printer & scanner chaosDrivers that break after every Windows update.
- Inventory mismatchCounts never match the shelf. Overselling and stale SKUs.
- Paid support headaches$200 service calls just to swap a receipt roll setting.
- No remote visibilityIf you're not at the store, you don't know what's selling.
