Electronic invoicing in Thailand
Characteristics of the electronic invoice in Thailand
E-invoicing in Thailand is voluntary; however, its use has been regulated by the Thai government since 2017.
The electronic invoice will be an XML (ETDA Standard). On the other hand, a PDF/A3 must be generated and sent to the end user.
E-invoices must be digitally signed using a certificate issued by a certification authority and approved by the Thai Revenue Department.
Invoice, credit notes, and debit note data must be exported monthly and sent to the Thai Revenue Department. This body will issue a validation response for the documents sent.
