Collect payments faster at counter and online! Enjoy lightning-fast 100% offline desktop GST billing with dynamic UPI QR code generation and instant online payment links via Customer Portal.

Revolutionize Counter & Remote Collections with Integrated Payment Gateway Billing

In modern commerce, friction during checkout leads to delayed payments, lower customer satisfaction, and extended credit cycles. Retail stores, wholesalers, and distributors need versatile payment solutions that cater to both walk-in customers paying via UPI and remote wholesale buyers paying via credit cards, net banking, or digital wallets.

InventoryPlus delivers an enterprise-grade solution by combining high-speed Offline Desktop GST Billing with multi-channel payment gateway and UPI integration. As our best-selling desktop billing application, InventoryPlus eliminates long customer queues while giving businesses powerful digital collection tools.

 Dynamic UPI QR Code Generation at Billing Counter

Instead of requiring customers to manually enter invoice amounts into UPI apps or relying on static QR standees where cashiers must visually confirm transactions, InventoryPlus generates Dynamic UPI QR Codes:

Invoice-Specific Amounts: The exact payable amount (inclusive of item prices, discounts, and GST taxes) is encoded dynamically into the generated QR code.
Dual Display Options: Display the QR code on a second monitor facing the customer, or print it directly at the bottom of thermal sales receipts.
Instant Verification: Reduces manual calculation errors and speeds up billing queue throughput by up to 50%.

Online Payment Gateway & Customer Self-Service Portal

For distributors, wholesalers, and service providers issuing credit invoices, receiving payments on time is crucial for maintaining cash flow. InventoryPlus pairs your desktop POS with InventoryPlus Online Cloud Sync & Customer Portal:

1. Digital Invoice Links: Send tax invoices directly via WhatsApp or SMS containing direct “Pay Now” links backed by leading payment gateways like Razorpay, PayU, or Paytm.
2. Customer Self-Service Portal: Buyers can log into their private account portal to review past invoices, inspect current credit limits, view account statements, and settle outstanding balances using Credit Cards, Debit Cards, Net Banking, or UPI.
3. Automated Ledger Sync: Once an online payment is processed, payment status updates across your desktop application automatically, balancing ledgers instantly.
