eInvoicing supplier onboarding guide

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

If you are ready or planning to start receiving eInvoices, this guidance will help you successfully onboard your suppliers. Use it to:

  • prioritise and plan your activities
  • identify and engage with suppliers who are ready to start eInvoicing you now
  • engage and encourage remaining suppliers to get onboard.

Who this guidance is for

This guidance is intended for people in medium to large organisations, including government, who are involved in managing supplier relationships and processing supplier invoices, including:

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

Key onboarding principles

  • Make supplier onboarding a core part of your eInvoicing implementation plan.
  • Start early and don't leave onboarding until the end – it's not a one-off activity and will take time.
  • Tailor your onboarding approach to align with your business objectives and plans.
  • Resource your onboarding activities and involve relevant teams across your organisation, including procurement, contract management, accounts payable and supplier-facing areas.
  • Test for multiple scenarios and requirements and pilot receiving eInvoices with a small group of reliable suppliers.
  • Look for quick wins that can help remove inefficiencies and set targets to build momentum.
  • Get support and commit to a continued transition across your organisation and suppliers - look for opportunities to make eInvoicing the default channel for current and future contracts.
