e-Invoicing cover

< Back to E-Invoicing Overview

South Africa is developing an e-invoicing framework as part of its broader tax modernization efforts. While not yet mandatory, the government is working towards digital invoicing to improve VAT collection, reduce fraud, and enhance efficiency.

Businesses adopting e-invoicing voluntarily benefit from streamlined financial processes, automated tax reporting, and greater compliance with South Africa’s VAT regulations.

Regulatory authority

The South African Revenue Service (SARS) is responsible for e-invoicing regulations.

E-invoicing requirements

E-invoicing is currently voluntary, but regulations are expected to become mandatory for VAT-registered businesses in the near future.

Accepted invoice formats

Invoices are expected to follow XML-based formats compatible with international e-invoicing standards.

Transmission channels

Invoices will be transmitted through a SARS-approved e-invoicing system.

Digital signatures

Digital signatures may be required in future regulations for authenticity and fraud prevention.

Archiving requirements

Invoices must be stored for at least five years under South African tax laws.

How B2B e-invoicing works in South Africa

Businesses generate invoices digitally and submit them through an authorized e-invoicing platform for validation.

How B2G e-invoicing works in South Africa

Government suppliers that adopt e-invoicing must submit invoices electronically for validation before payments are processed.
