SaaS teams often need a practical onboarding checklist more than another high-level architecture diagram. Before launch, make sure the product can answer the day-one operational questions clearly.

A useful pre-launch checklist

Confirm that your team has:

  • defined which customers go live first
  • clarified the sender data required for onboarding
  • confirmed the participant IDs that will actually be used
  • mapped core invoice fields to the Peppol flow
  • designed customer-facing statuses
  • agreed support ownership for failed cases
  • tested validation and retry handling

Add one receiver-readiness check to the checklist

Before launch, make sure the team also knows how it will confirm that a receiver is actually ready for live traffic.

That usually means being clear on:

  • which participant ID is expected
  • how the team checks whether the receiver can be found
  • who approves the final go-live signal

Without that step, onboarding can look complete while the last mile is still uncertain.

Why this matters

Launches go off track when one of these areas is missing. A technically working send flow is not enough if onboarding stalls or support cannot interpret document outcomes.

Keep the first phase narrow

The best rollouts often start with a focused scope:

  • one core document flow
  • one customer segment
  • one visible status model

That gives the team a chance to learn before scaling volume or complexity.
