Accounting that follows how Thai businesses work
ERP takes you from a quotation to a tax invoice and keeps your books in order along the way.
What you can do
- Quotations to invoices — create a quotation, turn it into an invoice or tax invoice, and keep the paper trail together.
- Automatic double-entry — documents post to the books automatically, so you do not re-key entries.
- VAT report (ภ.พ.30) — prepare the VAT figures you need for your monthly return.
- Withholding tax certificates (50 ทวิ) — issue the certificate when you withhold tax.
- Multi-company — manage more than one company under the same login.
