What is an e-invoicing platform?

An e-invoicing platform issues structured, machine-readable invoices (XML, UBL, JSON) in the format the local tax authority requires, signs them with the mandated artefact (CSID, IRN, UUID, QR, digital signature), and transports them to the authority through the prescribed channel (direct API, Peppol Access Point, SDI, NIC IRP, MyInvois portal API). Invoicemonk does this in 17 jurisdictions.

Which jurisdictions does Invoicemonk cover?

Saudi Arabia (ZATCA Phase 1 & Phase 2), Malaysia (MyInvois), India (GST IRN), the EU (Peppol BIS Billing 3.0), Nigeria (FIRS MBS), the UK (MTD for VAT), Kenya (KRA eTIMS), Ghana (GRA e-VAT), the Philippines (BIR CAS), South Africa (SARS), Zimbabwe (ZIMRA), Seychelles (SRC), Brazil (SEF), the US (federal B2G), and Canada (CRA + Peppol).

What artefact does Invoicemonk issue?

The local one. CSID for ZATCA, IRN + signed QR for GST India, UUID for MyInvois, control unit invoice number + QR for eTIMS, and digital signatures for Peppol, EU, and UK transports. Every artefact appears on both the PDF and the structured XML/JSON.

Do I need a separate plan for e-invoicing?

E-invoicing is on the Biz plan. The same plan covers every supported mandate — no per-jurisdiction add-on.
