What Document AI (OCR) is and how it helps your organisation

Every day the accounting and purchasing teams receive dozens of tax invoices, delivery notes and forms on paper or as PDFs. Staff key the figures into the system field by field, lose hours to repetitive work, and when a digit is wrong the correction ripples through the whole month. Thai handwriting and tables make it worse, because generic OCR tools simply cannot read them.

Khaojai IT's Thai OCR and Document AI takes a scan or a photo and lets the AI read Thai and English, printed and handwritten, including tables and stamps. It then extracts each field automatically, such as document number, date, vendor and amount. Fields the AI is not confident about are routed to a person for a quick check before the data is sent into your ERP or accounting system.

After go-live the accounting team stops rekeying. Every document becomes data that can be searched and audited later, typing errors fall away and the books close faster. Khaojai IT configures the OCR for the document types your organisation actually handles and connects it to the accounting or ERP system you already use.

Questions buyers ask before starting

How accurately does the OCR read Thai handwriting

The AI reads clearly written Thai handwriting well and shows a confidence level for every field. Low confidence fields are sent to a person first, so no wrong value enters your system unseen.

Can it send data into the accounting or ERP system we already use

Yes. It connects to SAP, Express, Oracle and other accounting systems through APIs or import files. If your current system has no API, our team designs an integration that fits your organisation.

How long does implementation take

It depends on how many document types you have. Typically 1 to 3 months, starting with the single document type that has the highest volume and expanding from there.

Is the document data secure and PDPA compliant

The system runs on your own servers or on cloud infrastructure in Thailand, whichever you choose, with access permissions and a complete usage log that supports PDPA requirements.
