Frequently asked questions

What does an invoice parser API do?

An invoice parser API accepts invoice files and returns structured JSON with named fields — invoice ID, vendor, due date, total, tax, currency, and line items — instead of raw text or unstructured OCR output.

Can it extract invoice IDs and due dates?

Yes. DocuParse API extracts invoice ID, document ID, invoice date, due date, and other structured fields from invoice documents.

Can it parse PDF invoices?

Yes. PDF is the primary supported format. JPG and PNG scans are also supported. Difficult layouts are handled automatically.

Can it return line items?

Yes. DocuParse API returns a line_items array with description, quantity, and amount for each billed item found on the invoice.

Is this useful for accounting automation?

Yes. Structured invoice JSON is ideal for feeding accounting software, triggering approval workflows, or populating ledger entries without manual data entry.

Does it support scanned invoices?

Yes. DocuParse API processes scanned invoice images and returns the same named fields regardless of scan quality.
