Raise a clean, compliant GST invoice in under a minute
GST billing software
Pick the party, add items, and RetailDek splits the tax into CGST, SGST or IGST by itself, prints the HSN summary, and rounds the total the way your accountant expects — every single time. GST invoicing software that runs entirely online, in your browser.
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.

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.
