What you can do

Built around how gst billing & invoicing actually works in an Indian shop.

Automatic CGST / SGST / IGST split

RetailDek reads the place of supply from the party and your company profile, then applies intra-state CGST+SGST or inter-state IGST automatically — no manual tax picking, no wrong splits.

HSN / SAC codes on every line

Each item carries its HSN or SAC code and GST rate, so the invoice prints a correct rate-wise and HSN-wise tax summary that lines up with your GSTR-1.

Auto round-off you control

Turn round-off on per document type in Settings. RetailDek rounds the grand total to the nearest rupee and stores the exact difference in a dedicated round-off column for a clean audit.

Custom number series & prefixes

Define your own invoice prefixes and sequences per company profile. The backend checks the prefix exists before accepting the number, so you never get gaps or clashing bill numbers.

Sale Order to Invoice in one step

Convert an accepted order straight into an invoice. Line items, party and taxes carry over, reserved stock is released and current stock deducted — all inside one atomic transaction.

Amount in words & UPI-ready totals

Totals print in Indian-format words (lakh/crore) and the invoice is ready to carry a UPI collect link, so customers can pay the exact amount without typing it.

How it works

Three steps, start to finish.

1

Choose party & items

Select a saved customer and start adding items. Rates, HSN codes and GST rates fill in from the item master automatically.

2

RetailDek does the tax maths

CGST/SGST/IGST is split from the place of supply, the rate-wise summary builds live, and round-off applies if enabled.

3

Save, print or share

Save the invoice against your number series, print a GST-compliant PDF, and stock updates instantly in the same transaction.

GST Billing & Invoicing — FAQs

Answers to the questions shop owners ask most.

Yes. Based on the party's state and your company profile's place of supply, RetailDek applies CGST + SGST for intra-state sales and IGST for inter-state sales automatically. You never pick the tax type by hand.
