Question 1

How do the per-item discount and the overall discount combine?

Accepted Answer

Per-item first: each line's Disc % reduces that line's total. The overall discount ( % or flat) then applies on the subtotal of those discounted line totals — never on the part the per-item discount already removed. Every row also has a duplicate button that copies it instantly below itself.

Question 2

Which invoice type should I use?

Accepted Answer

Use a GST tax invoice for taxable sales by a GST-registered seller, a bill of supply for exempt or composition supplies, a proforma invoice or quotation before the sale, and a credit or debit note to correct an invoice later. For other work, pick the template closest to your trade — the maths is identical; only the labels and extra fields change.

Question 3

How do CGST, SGST and IGST get decided?

Accepted Answer

By your state and the place of supply you select: same state splits the GST rate into CGST + SGST (half each), different states charge IGST at the full rate. If either is blank the tool treats the supply as intra-state, exactly like the printed hint says.

Question 4

Where does my data go?

Accepted Answer

Nowhere. The whole tool runs in your browser: the PDF is assembled on your device by a worker thread, your business profile and saved invoices (up to 50) live in this browser's local storage, and no network request is ever made.

Question 5

What happens when I click New invoice?

Accepted Answer

The client, items and notes are cleared, the date resets to today and the number bumps the trailing digits (INV/25-26/004 → 005), separately for each template. Your business profile, saved invoices and design settings stay.
