E‑invoicing regulations are government rules that define how organisations must create, send, receive, and store electronic invoices. They set approved data formats, required fields, submission channels, and timelines so tax authorities can verify transactions digitally and at scale.
These rules aim to improve tax compliance, accelerate digital transformation, and reduce fraud and errors through structured, machine‑readable data. Common features include mandatory use (for B2G, B2B, or both), standard formats such as UBL or UN/CEFACT CII, real‑time or near‑real‑time clearance or reporting, strong security and authenticity controls, legally compliant long‑term archiving, and cross‑border interoperability via networks like PEPPOL.
If businesses do not comply, invoices can be rejected and payments delayed, creating extra administrative work. Penalties and interest may follow, alongside increased audit scrutiny and reputational damage with customers, suppliers, and tax authorities.

The solution delivers continuously updated rules, pre‑built ERP integrations, and automated validation to reduce rejections, plus secure delivery and tracking (including PEPPOL where applicable) and compliant long‑term archiving with full audit trails, giving tax and finance teams clear visibility and control.
