Why agencies pick InvoiceOS
Inter-state GST, handled
Bangalore agency billing a Mumbai client? InvoiceOS auto-applies IGST. Bangalore billing Bangalore? CGST+SGST. You don't think about it.
Client address book
Save every retainer client's GSTIN, billing address, and PoC once. Future invoices auto-fill — no re-typing for monthly retainers.
Per-client invoice numbering
Numbers auto-increment so your books stay sequential — required for GST audit trail and clean Tally exports.
