OneBiz ERP
Localization

Odoo, localized properly
for Thailand

International ERP systems all hit the same wall in Thailand: statutory documents that do not match the Revenue Department format, no withholding tax handling, and financial statements local auditors cannot read. Here is how we close that gap.

VAT 7% and PP.30 reporting

Input and output VAT configured with purchase and sales tax reports formatted for Revenue Department filing.

Withholding tax and 50 Tawi

Automatic WHT calculation by income type, withholding tax certificates, and PND.3 / PND.53 monthly summaries.

Compliant tax documents

Full and abbreviated tax invoices, debit notes, credit notes and receipts with the wording and fields Thai law requires.

e-Tax Invoice & e-Receipt

Integration with certified service providers for electronic tax invoice submission and delivery status tracking.

Thai chart of accounts

A chart of accounts your Thai auditor recognises, with financial statements ready for DBD submission.

Thai calendar and Buddhist era

Thai public holidays, Buddhist era dates on documents, and correct Thai Baht formatting throughout.

PromptPay and bank reconciliation

PromptPay QR on invoices plus bank statement import and reconciliation for Thai banks.

Bilingual interface

Thai for your local team, English for expatriate management — same database, same records, per-user language.

Why this matters more than feature lists

Companies usually select an ERP on front-office features, then discover that the accounting team still exports everything to Excel every month because the system cannot produce statutory reports in the required format. You end up paying for an ERP and keeping the manual work.

Getting Thai compliance right from day one is therefore not a nice-to-have — it decides whether the system is genuinely used. That is why we built OneBiz ERPon top of Odoo with the Thai statutory layer already in place.

This page describes system configuration approaches. It is not legal or accounting advice — always confirm details with your auditor or tax adviser.
FAQ

Frequently asked questions

Not out of the box. Odoo has a flexible tax engine, but income-type classification under Thai law, withholding tax certificates (50 Tawi) and the PND.3 / PND.53 summaries require additional development. We ship these as part of our localization.
