E-invoices (UBL & CII)

Time needed: About 10 minutes

What are e-invoices?

E-invoices are machine-readable XML files that accounting tools can import. BridgeSync supports UBL (EU standard) and CII (Factur-X/ZUGFeRD). Most stores only enable these when a B2B customer asks for them.

Enable UBL or CII attachments

E-invoice attachments are configured on the Dashboard.

  1. Go to PDF Invoices → Dashboard
  2. Find the UBL e-invoice (XML) section
  3. Enable Attach UBL to Processing/Completed emails
  4. Find the CII / Factur-X (XML) section
  5. Enable Attach CII to Processing/Completed emails if required
  6. Click Save changes

Hybrid PDFs (PDF/A-3)

Some accounting tools require a PDF that embeds the XML file. BridgeSync supports hybrid PDFs using PDF/A-3.

  1. Go to PDF Invoices → Validation & Formats
  2. Scroll to the PDF/A-3 hybrid section
  3. Enable Embed UBL (XML) into PDF (PDF/A-3) or Embed CII (XML) into PDF as Factur-X/ZUGFeRD
  4. Click Save changes

If the conversion fails, BridgeSync falls back to a standard PDF.

Validation and formats

Validation checks ensure your XML files follow the official rulesets. This is helpful for B2B and government invoicing.

  1. Go to PDF Invoices → Validation & Formats
  2. Under UBL validation, choose a validation mode (Warn is recommended)
  3. Under CII validation, choose a validation mode
  4. If you invoice German public sector clients, enable XRechnung (UBL profile)
  5. Click Save changes

Verify e-invoices

  1. Create a test order and mark it Completed
  2. Resend the Completed email to yourself
  3. Confirm the XML files are attached alongside the PDF

Verify

Success: Customers receive UBL or CII XML files along with the PDF invoice when requested.
