FAQ
Questions about billing and gst
Does OMMS create GST-compliant invoices?
OMMS generates tax invoices with your GSTIN, the client’s GSTIN, place of supply and IGST or CGST/SGST, and downloads them as PDF. Your accountant should confirm the format meets your filing needs.
Can one PO cover several campaigns?
Yes. A client PO can be linked to more than one campaign, and invoices can be generated in bulk from POs.
Can I raise a proforma first?
Yes. Proformas are separate from tax invoices and can be raised from a campaign before the final bill.
