Why It Matters

The big idea: three parts, not one project.

Most people picture an automated integration as a single project. It’s really three separate parts — and seeing them makes the work, the ownership, and the cost clear. We provide the APIs, free. You own the build.

The 3 Components of Any Integration
  1. 01
    Connecting to your ERP
    You or a partner
  2. 02
    Mapping data between systems
    You or a partner
  3. 03
    Connecting to Stella Source
    Stella Connect — free
Each part has different work and a different owner.
What’s Included vs. What You Build

Free to connect. Yours to build.

The endpoints you need to connect your ERP to Stella Source are free; the build that’s specific to your systems is yours (or a partner’s).

Included with every plan

  • Stella Connect — our API gateway that receives, processes, monitors, and error-handles your data
  • 6 open API endpoints, fully documented
  • Bidirectional data flows
  • Introductions to pre-vetted partners, if you need one

What you build (or a partner builds)

  • The connection to your specific ERP
  • Mapping data between Stella Source and your systems
  • Your dev team’s time, or a partner’s scope and quote
  • Pricing set to your ERP, your data, and your complexity

Frequently asked questions

Are integrations included in my plan?

Free, unlimited access to Stella Connect — our full API gateway and documentation — is included in every plan. Connecting your specific ERP to Stella Source is a separate implementation, handled by your dev team or a vetted partner.

Does Stella Source build the integration for me?

No. We provide the API gateway and complete documentation, plus introductions to pre-vetted partners if you need one. The build itself is done by your development team or a partner.

How much does an integration cost?

Access to our APIs costs nothing. The build depends on your ERP, the data you’re syncing, and where it lives. If you use a partner, they’ll scope it on a short discovery call and send a quote.

Do I need integrations before I go live?

Usually not — and we often recommend against it. Get live, generate revenue, then connect the systems that matter. Read The Integration Trap for the full argument.

Which ERPs can Stella Source connect to?

Stella Connect works with any ERP that offers an API or data access. We’ve built 200+ integrations across a wide range of ERP systems, so we’ve seen virtually every edge case.
