# Invoicemonk

> The global e-invoicing platform for small business: mandate-compliant in 18 jurisdictions across the Middle East, Asia-Pacific, Europe, Africa, and the Americas. Every invoice carries the local cryptographic artefact (CSID, IRN, UUID, QR, Chave de Acesso, or fiscal signature) and is delivered through the mandated transport (direct API, Peppol Access Point, or national portal).

Invoicemonk is the e-invoicing platform built for freelancers, consultants, contractors, and small businesses that need structured, mandate-compliant invoices in every country they work in. The platform issues and submits e-invoices that meet the legal requirements of the local tax authority: clearance with ZATCA Fatoorah, validation by LHDN MyInvois, IRN issuance by NIC IRP and FIRS MBS and GRA E-VAT, Control Unit Invoice Number by KRA eTIMS, Peppol BIS Billing 3.0 routing across the EU and Canada, MTD digital VAT records for HMRC, and SARS, ZIMRA, SRC, NF-e/NFS-e, BIR EIS, and US IPP for federal B2G.
