- Case / outer and loose quantity
- Wholesale goods move in cartons and outers but are often broken into loose pieces for small retailers. Showing both the pack size and the number of cases avoids disputes when a retailer counts the delivery against the bill.
- Trade discount column
- Wholesale prices are quoted as a discount off MRP or list price. A separate discount column, deducted before tax, proves the taxable value was reduced at the time of supply and keeps GST calculated on the lower figure.
- Retailer's GSTIN and shop name
- Most counter buyers are registered kirana, general and stationery stores who need the credit. Printing the exact GSTIN they registered with, not the owner's personal name, lets the invoice flow correctly into their GSTR-2B.
- Salesman / route code
- Wholesalers send salesmen on fixed beat routes. A route or salesman code on the bill makes it easy to track collections, commissions and returns by route without a separate register.
- Credit days and due date
- Retailers usually buy on 7 to 30 days' credit. Printing the due date and the agreed credit days on the invoice gives a clear reference for follow-up and for any interest you charge on late payment.
- E-way bill number and vehicle
- Consignments above Rs 50,000 moved by tempo or truck need an e-way bill. Noting the EWB number and vehicle number on the invoice links the document the officer checks on the road with your tax invoice.
