Features
It doesn't just see the invoice. It understands it.
Extract & Post
Reads Thai and English invoices: supplier, amounts, dates, line items, VAT, WHT. Then posts them to the right accounts. Handles handwriting, stamps, and the messiest scans.
Smart Split
Upload one file with ten invoices from different suppliers. A3 detects where each one starts and ends, and splits them automatically.
Chart of Accounts Learning
A3 learns from every correction you make. After a few invoices per supplier, it picks the right account code without asking.
Full Tax Compliance
WHT certificates, PND 53, 50 Tawi, PP.30 VAT returns, monthly reports: all auto-generated and TFRS-compliant. Revenue Department format, every time.
Client Auto-Routing
A3 spots the client name on every invoice and routes it straight to the right account. No more sorting by hand.
One-Click Posting
Post to Xero, QuickBooks, PEAK, FlowAccount, or Odoo. Batch-post hundreds at once. Full audit trail from invoice to journal.
