Opticidigit is a software application designed specifically for optical shops, providing tools for billing, inventory management, customer relationship management, and prescription tracking. It integrates GST compliant billing with the ability to include eye power details (such as SPH, CYL, AXIS, and PD) directly on invoices, and automatically stores this data in a customer’s eye test history. The software is used by optical shops of various sizes across India, from small independent outlets to larger chains and enterprises. It is registered as an MSME (Udyam) and recognized by DPIIT under Startup India. The system includes point-of-sale (POS) functionality, stock management with barcode generation, and automated reminders for birthdays, eye test due dates, and contact lens reorders. These reminders can be sent via SMS or WhatsApp from the shop’s own number. Inventory is managed by adding items with name, price, quantity, and low stock level; barcode labels can be printed with the shop name, brand, model, and MRP. Scanning a barcode at the counter automatically populates the bill. The software supports a range of frame materials and terminology commonly used in optical shops. Opticidigit is available as native applications for Android, iOS (iPhone and iPad), Windows, Mac, and as a web app that works online or offline. It can print bills with eye power on Bluetooth thermal printers. Premium plans (Pro and Pro Ultra) include a 2 in 1 printer for both bills and barcode price labels. The software is priced starting at ₹2,500 per year. It has received ratings on platforms such as G2, Capterra, Google, and Product Hunt, and is featured on software directories. A free demo is available.
