Why these tools exist
A customer payment tracker is only useful if the numbers around it are honest. These calculators run in your browser. Nothing is uploaded. Use them before you open a ledger, or send a screenshot to a customer who will not install an app.
Start with the job in front of you. If a supplier quoted an MRP-style figure, open the GST calculator and take tax out. If you are printing a bill, use the GST invoice generator so CGST/SGST versus IGST is picked from place of supply. If a customer is paying something against an open due, use the receipt generator so both of you walk away with the new balance. Interest, EMI and late fee are for the sentence you say before anyone signs.
No account, and not a government service
None of these pages file a return, talk to GSTN, or move money. They do the arithmetic a kirana counter already does on a phone calculator, with the split and the day-count written down so you can show the screen. Confirm rates and HSN codes with your accountant. Embed any calculator on your own site with the widget builder if you write for shopkeepers. The signed-in DueSetu ledger is a different surface: that is the khata, and it does need a login.
