ERP integration checklist for e-invoicing rollout teams

1. Define the target scope first

For Define the target scope first, review these points before moving on.

• List which countries, recipient types, and channels are in scope for phase one.
• Define the target formats per workflow: XRechnung, ZUGFeRD/Factur-X, UBL, or CII.
• Decide whether the ERP will generate the final XML or whether a conversion service will act as the integration layer.

2. Clean the source data before mapping

For Clean the source data before mapping, review these points before moving on.

• Review seller and buyer master data, tax identifiers, addresses, IBANs, and payment terms.
• Check that line items, discounts, allowances, charges, and VAT categories are stored consistently.
• Mark fields that need enrichment outside the ERP, such as a buyer reference or Leitweg-ID.

3. Design the mapping and validation path together

Design mapping and validation together. Missing required fields and code-list mismatches are easiest to catch while the ERP-to-XML mapping is being defined.

• Map every required field to a known ERP source or an explicit fallback workflow.
• Confirm the code lists for VAT categories, payment means, currencies, and country codes.
• Decide which validation reports to retain and who is responsible for correcting rejected invoices.

4. Build an exception workflow before go-live

For Build an exception workflow before go-live, review these points before moving on.

• Define who reviews uncertain extracted data and missing identifiers.
• Document when to regenerate an invoice from source data instead of editing the XML.
• Set response times for validation failures so finance teams know what blocks transmission.

5. Test with realistic invoice samples

For Test with realistic invoice samples, this sequence gives the practical order of work.

1. Test simple domestic invoices first.
2. Then test discounts, mixed VAT rates, exemptions, credit notes, and recipient-specific identifiers.
3. Run end-to-end tests through the target delivery channel and any downstream import or portal.

6. Involve operational owners before go-live

For Involve operational owners before go-live, review these points before moving on.

• Train finance users on what to review before sending.
• Expose validation status and correction ownership clearly in the daily workflow.
• Keep a manual handling path for invoices that cannot yet pass automatically during the first rollout wave.
