How Retailers Can Automate Billing with ERP

Manual Billing Is Killing Your Customer Experience

Long billing queues, slow processing, billing mistakes, manual GST calculations, and handwritten receipts — these create poor customer experiences and lost sales. In 2026, customers expect fast, professional, digital billing as a minimum standard.

ERP billing automation transforms your checkout experience from frustrating to exceptional — while making your operations more accurate and GST-compliant simultaneously.

5 Billing Processes ERP Automates Completely

1. Price Auto-Fill from Product Master

Search an item by name, code, or barcode scan. The current price, discount, and GST rate fill in automatically — no manual price lookup or calculation needed.

2. GST Calculation

CGST, SGST, or IGST calculates automatically for every item. Total bill amount, tax breakup, and net payable are all calculated without any manual input.

3. Customer Selection with Credit Check

Select the customer and the system: fills in their GSTIN, checks their credit limit, checks outstanding dues — and alerts if they've exceeded their limit before confirming the bill.

4. Payment Mode Recording

Record cash, UPI, card, or credit payments with a single tap. Multiple payment modes for one invoice are handled correctly. Outstanding balance is tracked automatically.

5. Invoice Sharing — Zero Paper Needed

Share the finished GST invoice via WhatsApp with one tap. Email option also available. No printing needed unless the customer specifically requests it — reducing paper costs significantly.
