Electronic invoicing will be rolled-out in two phases in KSA (more details about the phases here [link to the following page]). For the first phase, enforceable as of December 4th, 2021, for all taxpayers (excluding non-resident taxpayers), and any other parties issuing tax invoices on behalf of suppliers subject to VAT, electronic invoice issuance will be very similar to today, with invoices issued through a compliant electronic solution and including additional fields depending on the type of the transaction

Taxpayers may choose any e-invoicing solution provider as long as it is compliant with the e-invoicing requirements. ZATCA will consider the taxpayer's complaint if he is complying with the e-invoicing requirements even if the solution provider is not listed on the indicative list.
The indicative list of the solution providers on ZATCA’s website who have passed the qualification process and criteria aims to allow the taxpayers to easily reach potential solution providers.
