Accounting and advisory firms

Client invoices and receipts extracted and reconciled

Invoices, payment receipts and bank ownership certificates with tax IDs and IBANs validated.

The problem

Invoices as PDFs, photos or screenshots in different layouts.
Typos in tax IDs and amounts.
Manual Excel exports for bookkeeping.

With Constaia

Tax IDs and totals checked.
XLSX, CSV or XML export in the same call.
Batches of up to 100 documents with a webhook when done.
