About POSflow

We build software we would trust to run our own business.

Most business software either feels too generic or too fragile. We started POSflow with a simple goal: build software that actually fits the pace and reality of real operations.

Today, POSflow operates as a hybrid: we build and maintain our own SaaS products like RestaurantOS, and we partner with ambitious companies worldwide to design, develop, and deploy custom software.

Because our engineers run live production systems processing real orders every single day, our custom engineering isn't just code in a presentation — it's proven, reliable, and built to last.

Ready-Made Products

Battle-tested systems like RestaurantOS and Retail POS that you can download, install, and run today without long build times.

Custom Software Engineering

Full-cycle engineering for companies needing bespoke web platforms, iOS/Android apps, desktop software, or API integrations.

Long-Term Human Support

We don't hand off code and disappear. We provide ongoing maintenance, cloud updates, and direct support from the actual engineers.

Zero Downtime Architecture

See what happens when the internet drops

In a busy restaurant, internet outages happen. POSflow uses an embedded local SQLite engine so your counter never freezes, orders keep printing, and queues keep moving.

Offline SQLite Mode Active

Billing continues with 100% speed

When your router disconnects or 4G data fails, POSflow does not throw an error or show a spinning wheel. Orders save directly to your computer's local drive and thermal receipts print instantly.

Instant Order Punching

Cashier takes orders with zero loading lag. Menus and combos load from local cache.

Thermal ESC/POS Receipt & KOT Printing

Cash drawer kicks open, receipts cut, and kitchen order tickets print over USB/LAN.

Encrypted Local Storage

SQLite ACID transactions protect every bill from corruption, even if power shuts off suddenly.
