What every invoice gets right
GSTIN checks before you save
GSTINs are checked for format, state code and checksum, so a typo is caught before it reaches your return.
HSN and SAC codes
Search and validate HSN/SAC codes on products. The pre-filing check warns when codes are shorter than your turnover requires.
Multi-rate, cess and reverse charge
Mix tax rates on one invoice, add compensation cess, and flag reverse-charge supplies so they are reported correctly.
Credit and debit notes
Sales returns raise credit notes linked to the original invoice, and flow into GSTR-1 and GSTR-3B net of returns.
Invoice numbering by financial year
Set your own prefix, padding and separator with the financial year built in, e.g. INV/26-27/1042.
e-Invoicing: IRN and signed QR
Businesses above the notified turnover threshold must report B2B invoices to the Invoice Registration Portal. OthTech prepares the standard e-invoice JSON from your invoice and fetches the IRN, acknowledgement number and signed QR through your GSP. A GST audit report lists B2B invoices that still need an IRN.
e-Invoicing is available on the Standard plan and above, and live IRNs need your own GSP account. Check the current e-invoicing threshold with your CA.
