This section is for **technology partners** building an integration that connects **multiple customers** to Pleo, typically for distribution through the Pleo App Marketplace or as a supported partner solution.

If you're connecting only your own company's system to Pleo, use the [Pleo Customers Quickstart](/docs/current/getting-started/pleo-customers-quickstart) instead.

All partner integrations go through Pleo's **Early Access Programme (EAP)**.

<RememberCallout title="Remember">
  Set your expectations: registering your interest in the EAP is a request, not a guarantee of access. Pleo's partnerships team reviews each request, and only moves your integration forward if it meets the programme's requirements.
