Project overview
POS · Book Fair · Mobile App · Offline Billing
FairMPOS is designed to be easy to use and adaptable to your fair's needs. While we offer a personalised onboarding process to ensure a smooth setup, FairMPOS's intuitive features require minimal training. Our functionalities, like the intelligent barcode scanner, pre-set discounts, and offline billing capabilities, are built to streamline your fair's operations right from setup.
Running a book fair counter means dealing with high footfall, rapid transactions, inconsistent internet connectivity and the constant pressure of long queues. FairMPOS solves all three: the intelligent barcode scanner reads ISBN barcodes instantly, pre-set discount rules apply automatically at the point of sale, and the offline billing engine keeps the counter running even when the internet drops — syncing all transactions when connectivity is restored.
FairMPOS works as both a mobile Android app and a web application, so your team can run counters from phones, tablets or laptops — whatever hardware is available at the fair. The app integrates directly with the WASS Book Trade ERP, meaning stock levels update in real time across all counters and the day's sales post to the accounting ledger automatically at close.
The personalised onboarding process means your title catalogue, discount structures and counter configuration are set up before the fair opens — not on the morning of day one. Every transaction is logged with a full audit trail, and end-of-day reports give the fair manager a complete picture of sales by title, category, counter and payment method.
