Billingoapp, presented as POSpro, offers a software-as-a-service point-of-sale system designed to bring sales and business operations together in an online platform. Its Flutter-based app is available for Android, with a web offering and an administration panel. The system supports offline use with synchronization and is promoted for businesses seeking an alternative to legacy point-of-sale software.

Features include sales processing, customer and supplier records, purchasing, product and inventory management, due-list tracking, income and expense records, and stock loss and profit reporting. The platform advertises support for more than 47 languages and multiple currencies, alongside a dashboard and a mobile app that can be downloaded by scanning a code. Billingoapp offers free, standard, and premium subscription options, with listed terms of seven, 30, and 180 days respectively. The plans advertise updates, technical and live support, messaging support through WhatsApp and Skype, and installation assistance. The site identifies Acnoo as a theme, web, plugin, and app development agency and provides account registration, pricing, contact, and policy information.
