Other free billing apps make pretty PDFs. Apna Invoice is engineered around 12+ specific CGST Rules, so the document you issue today still passes muster when your CA opens GSTR-1 next month. No silent edge cases. No "we don't support that case." Audit-defensible by design.
Title is decided by your data, not a dropdown. No GSTIN → "Invoice". Composition dealer → "Bill of Supply" + Rule 49 footer note. Regular registered → "Tax Invoice". Always legally correct.
Place of supply is computed from your state vs. the customer's state. Inter-state? IGST. Intra-state? CGST + SGST split to the paisa, with proper round-off. No manual math.
Set "books locked until 31 Mar" once your CA signs off. After that, the system blocks editing or backdating any invoice, payment, expense, credit note, or cash memo into the closed FY. Audit trail logs every lock.
Credit notes can only reduce GST liability if issued by 30 Nov of the FY following the supply. We compute the deadline per invoice and block late issuance, politely, so you never file a worthless CN.
Tick "RCM applicable", tax is zeroed out, the recipient declaration "Tax payable on reverse charge basis" prints automatically per Rule 46(p), GSTR-1 marks it correctly. Done.
New 40% sin/luxury slab. New 1.5% / 7.5% under-construction housing rates. Merchant export 0.10%. All loaded, pick the right slab from the dropdown, the system does the rest.
