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
  • mapped core invoice fields to the Peppol flow
  • designed customer-facing statuses
  • agreed support ownership for failed cases
  • tested validation and retry handling

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.
