For business‑to‑business (B2B) transactions, Egypt operates a mandatory e‑invoicing regime for all VAT‑registered entities. Paper invoices become invalid for input VAT deduction purposes unless issued under valid e‑invoice regimes.
Invoices must be created in the approved XML/JSON format, digitally signed, and transmitted via the ETA portal/API so that they are validated and assigned a unique identifier (UUID) before issuance.
