Proper GST invoices with the CGST and SGST split, ready to print or share on WhatsApp.
Udhaar khata
Credit sales go straight into the customer's ledger, and you can send a payment reminder on WhatsApp.
Stock that updates itself
Every bill reduces stock, and low-stock alerts tell you what to reorder.
