Frequently Asked Questions

What GST slabs apply?

5%, 12%, 18%, and 28% depending on item category — the tool applies the right slab per line item.

CGST+SGST or IGST — which?

Intra-state sales split CGST and SGST equally; inter-state sales use IGST in full.

What details go on the invoice?

Seller and buyer GSTINs, HSN-coded line items, taxable values, tax split, and totals.

Are HSN codes mandatory?

Yes for registered businesses — requirements tighten with turnover; the tool includes HSN fields.

How many free invoices and what logo works?

3 free invoices per month — the meter shows remaining out of 3 and blocks the 4th for free users. Logos must be PNG/JPG under 500KB (500 x 1024 bytes) and are embedded scaled to fit 120x50 on the A4 page. GSTIN fields validate exactly 15 characters. Example: default line Consulting Services x1 at Rs.10,000 with 18% gives Rs.1,800 tax.

Can I use it for services too?

Yes — SAC codes cover services the same way HSN covers goods.

Is my business data uploaded anywhere?

No — invoices generate locally in your browser; free users can generate 3 invoices per month, Pro unlimited.
