Everything you need to know about OpenBill Pro, OpenSoz initiative, GST compliance, and payment settlement.
OpenBill Pro is an open-source web and mobile application developed by OpenSoz—an open digital platform initiative for Indian MSMEs. It is built to provide small retailers, wholesalers, and independent professionals with high-speed GST billing, 0% fee dynamic UPI QR codes, and WhatsApp invoice dispatch without paying steep corporate software fees.
OpenBill Pro generates standardized National Payments Corporation of India (NPCI) deep link strings (`upi://pay?pa={your_upi_id}&pn={shop_name}&am={total}`). When customers scan with Google Pay, PhonePe, Paytm, or BHIM, the money moves peer-to-merchant directly into your linked bank account. OpenBill Pro does not hold your funds and deducts zero percent (0%) MDR commission.
OpenBill Pro integrates with OpenWA QR session technology. You simply scan your shop's WhatsApp Web QR code once from your smartphone. Invoices and balance reminders are then dispatched directly from your own authenticated number, eliminating Meta official per-conversation API fees completely.
Our pricing is the most accessible in India: Free Trial (₹0) gives 7 days full access. Starter Plan (₹49/month) unlocks unlimited invoices, WhatsApp dispatch, custom UPI QR, and customer khata. Pro Plan (₹99/month) adds Meta official WhatsApp API readiness, automated UTR verification, 4 PDF themes, and 100% white-label zero branding.
Yes! When you create an invoice, OpenBill Pro compares your shop's state with the customer's billing address. For intra-state sales, it automatically splits the tax into equal CGST and SGST amounts. For inter-state trade, it seamlessly computes IGST in full accordance with GST Council regulations.
At month-end, simply navigate to the GSTR-1 module and click "Export CSV". The engine segregates registered business clients (B2B) and retail shoppers (B2C), generates HSN/SAC code summaries, and formats the output ready for direct upload to the official GST portal or your CA's audit software.
Yes! OpenBill Pro is fully compatible with standard 58mm (2-inch) and 80mm (3-inch) Bluetooth, USB, and Wi-Fi thermal receipt printers used at retail POS cash counters, alongside standard A4 vector PDF downloads.
Yes. OpenBill Pro is built as a cloud-synchronized Progressive Web App (PWA). You can bill at the counter on your mobile phone or use a widescreen desktop monitor in your back-office. All invoices and ledgers sync in real-time.
Absolutely. Because OpenBill Pro is an open platform initiative, we have zero corporate motive to monetize your data. We never sell, rent, or trade your billing amounts or customer contacts to advertisers or loan brokers. Your data is protected by 256-bit TLS 1.3 encryption and hosted locally in AWS Mumbai.
After 7 days, your existing bills and customer records remain completely safe and accessible. To create new bills, simply choose the Starter plan (₹49/mo) or Pro plan (₹99/mo) with instant UPI activation. There are no lock-ins, and you can export all your records anytime.
If you ever decide to delete your account, we place it in a 7-day security grace period. If you change your mind, a single click restores your account. After 7 days, our automated purge engine executes a permanent cascade deletion of all your records.
