**Quick answer:** No. AccountsOS keeps the books, works out the figures and tracks every date. It does not issue e-Tax Invoices or submit P.P.30, P.N.D. returns, SSO forms or DBD filings. You or your accountant file.

## Detailed explanation

## What AccountsOS does

- Keeps the ledger in baht
- Works out P.P.30 VAT figures, CIT estimates, withholding and Social Security
- Tracks P.N.D.50, P.N.D.51, P.P.30, P.N.D.1, 3 and 53, SPS 1-10 and the DBD filing

## What it does not do

- Issue e-Tax Invoices or e-Receipts to the Revenue Department. The e-Tax Invoice system is an option you join through your own registered channel. A PDF invoice from AccountsOS is an ordinary document.
- File any return with the Revenue Department, the Social Security Office or the DBD.
