Peppol BIS 3.0 in Sage

Sage offers Peppol through different mechanisms depending on product: Business Cloud Accounting has native integration, Sage 50 requires third-party add-ons, and X3 uses the Electronic Documents module. This guide covers all three paths, with focus on UK-specific configuration including VAT-based Peppol IDs and the IBAN formatting requirements that cause BR-DE-19 failures for cross-border invoices.

Prerequisites
  • Sage Business Cloud Accounting with Peppol subscription tier, OR
  • Sage 50 with partner add-on (Tungsten Network, Basware connector), OR
  • Sage X3 with Electronic Documents module licensed
  • UK: VAT registration number (forms basis of Peppol ID with scheme 9932)
  • Bank details in IBAN format (required for cross-border Peppol invoices)
Step-by-step setup
  1. 01

    Enable Peppol based on your Sage product

    Business Cloud Accounting: Connected Services → Peppol Integration → Enable. Sage 50: requires partner add-on—contact your Sage partner for Tungsten Network or Basware connector installation. Sage X3: Administration → Setup → Electronic Documents → Peppol module → Activate. Each product has different capability levels; Business Cloud is most integrated.

  2. 02

    Configure your UK Peppol Participant ID

    UK companies use VAT number as Peppol ID with scheme 9932. Format: 9932:GB123456789. Enter in: Business Cloud → Settings → Company → E-Invoice Settings. Sage 50 → Settings → Company Details → Peppol tab (from add-on). X3 → Common data → Company → Electronic address. The Peppol directory will show your registration once your Access Point completes onboarding.

  3. 03

    Convert bank details to IBAN format

    Cross-border Peppol requires IBAN format bank details. UK sort code + account number converts to IBAN: GBxx + BANK (4 letters) + sort code (6 digits, no dashes) + account number (8 digits). Use online IBAN calculator with your bank's BIC code. Update in company bank details. Domestic UK invoices work with sort code, but EU recipients need IBAN—causes BR-DE-19 for German recipients.

  4. 04

    Add customer Peppol Endpoint IDs

    For each Peppol-enabled customer: Customer record → e-invoicing tab → Peppol ID. Look up customer at directory.peppol.eu. EU customers: use their country-specific scheme (0106 NL KVK, 0208 BE KBO, 9930 DE VAT, etc.). UK customers: 9932:GB + VAT number. Customers without directory registration cannot receive Peppol invoices.

  5. 05

    Test Peppol transmission and check MTD integration

    Create test invoice for Peppol customer → Send via Peppol option. Check transmission status in e-invoicing dashboard (Business Cloud) or add-on console (Sage 50). Verify delivery confirmation from Access Point. Note: Peppol e-invoicing data can complement MTD (Making Tax Digital) compliance—structured invoice data supports digital VAT records requirements.
