e-Invoicing in Thailand is the e-Tax invoice and e-Receipt system for issuing electronic tax invoices and receipts in accordance with the Revenue Department of Thailand’s rules, with technical standards set by the Electronic Transactions Development Agency (ETDA). Thailand e-invoicing system follows a periodic reporting framework, meaning the invoices are not reported to the government in real time but at a later stage.
Under Thailand e-invoicing, the seller sends electronically signed invoices to the buyer as soon as the transaction is created, either in PDF or XML, depending on their agreement. And by the 15th of next month, those invoices have to be reported to the Revenue Department, which sends back an acknowledgment. Our Thailand e-invoicing add-on for Sage ERP automates the e-invoicing flow, including validation of invoices in ETDA XML and invoice data transmission to the buyer and the e-tax portal via an e-tax service provider.
To operate within the e-Tax Thailand system, sellers must register with the eTax portal, use standardized file formats, embed digital signatures, and submit invoice data to the Revenue Department periodically.
