Illustration of the checklist we run for every client, every month.

The problem

Thai compliance runs on a monthly clock.

Withholding tax, VAT and Social Security returns are due every month, and late or incorrect filings carry surcharges. Books kept loosely through the year also make the annual audit slower and more expensive.

System Accounting keeps your ledger reconciled each month, so every filing, every report and your year-end audit draw on the same clean numbers.

FAQs

Questions about System Accounting.

Something else on your mind? Ask our advisors on LINE or WhatsApp.

How is the monthly fee set?

By the number of transactions, employees and filings each month. We quote a fixed fee after reviewing a sample month.

Can you take over mid-year?

Yes. We pick up from the last completed month and fix any gaps we find in earlier records.

Do I need to send original documents?

Scans or photos are fine for monthly work. Keep your originals, as the law requires them to be retained.

Do you file VAT if we are not VAT-registered?

If you are not registered, we file withholding tax only, and we tell you when your revenue nears the registration threshold.

See your books the way we'd report them.

Send us one month of documents. We'll show you what your monthly report would look like and quote a fixed fee.
