eInvoicing changes the way businesses receive and process invoices, and also how their suppliers send invoices.

If your business is eInvoice-enabled, or planning to become enabled, this guidance will help you to successfully onboard your suppliers. Use it to:

  • prepare, prioritise and plan with our onboarding checklist (see Appendix 1)
  • prepare for internal process changes, including staff training and internal communications (see Appendix 2)
  • identify your suppliers and communicate with them (see Appendix 3).

This guidance is designed for people in medium to large entities involved with processing accounts payable (supplier) invoices, including:

  • finance, particularly accounts payable
  • procurement, contract or supplier account managers
  • eInvoicing implementation project teams
  • communications change teams.

Key onboarding principles

The following principles will help make the changes easier for everyone:

  • Plan onboarding as part of your technical implementation. Make it part of your roadmap.
  • Partner with your finance and procurement teams and with other relevant business areas.
  • Don't leave onboarding until the end. Engage and communicate with your suppliers early.
  • Test for multiple scenarios and requirements with a small group of reliable suppliers before making it business as usual.
  • Set targets and manage your supplier onboarding efforts.
  • Look for opportunities to make eInvoicing the default channel for current and future contracts.
