SnelUBL converts PDF, DOCX and image invoices to validated UBL 2.1 or UBL 2.3 XML for use with Exact Online. You review the data, download the UBL file and import it by following Exact Online's current UBL instructions.
From source invoice to Exact Online in three steps
1. Submit the invoice
Upload a PDF, DOCX, PNG, JPEG, HEIF/HEIC or WebP file in Quick Mode, or use a workflow for recurring files.
2. Review the conversion
Review the recognized supplier, customer, invoice lines, totals, currency and VAT. Correct data where needed before exporting the validated UBL file.
3. Download and import the UBL
Download the UBL from SnelUBL and follow Exact Online's current UBL import instructions. SnelUBL does not claim a direct export integration for Exact Online.
Automate with an inbox or cloud folder
Give a workflow its own inbox or collect files from Dropbox, OneDrive/SharePoint or Google Drive. SnelUBL detects attachments, processes invoices and sends status emails. API access is available for custom automation.
