# Acceptor boarding overview

> Learn how to onboard acceptors to Tesouro using GraphQL mutations to create, update, and submit applications for underwriting.

<Warning>Acceptor boarding is in Beta and not ready for production integration.</Warning>

To onboard a new acceptor to Tesouro, you'll use a series of GraphQL mutations to create and submit an application. The flow is flexible — you can either submit a fully completed application in a single request or progressively build the application over multiple steps.

<Note>
  A developer at Clearpath Payments is using Tesouro's acquiring API to board Maple Street Coffee as
  a new sub-merchant acceptor. They need to create an acceptor application that includes the
  business details, stakeholder information, and bank account details before Maple Street Coffee can
  begin processing transactions.

## Boarding steps

<Steps>
  <Step title="Explore billing profiles">
    Query available billing profiles and their allocations to understand the fee structures available for your acceptor. See [Explore available profiles](/acquiring/boarding/manage-billing/explore-available-profiles).
  </Step>

  <Step title="Create the application">
    Create an acceptor application with a billing profile, stakeholders, bank accounts, and other required data using `createAcceptorApplication`. See [Create an application](/acquiring/boarding/acceptor-applications/create-application).
  </Step>

  <Step title="Add or update details">
    Add any missing information — stakeholders, bank accounts, or required fields — using `updateAcceptorApplication`. See [Update an application](/acquiring/boarding/acceptor-applications/update-application).
  </Step>

  <Step title="Submit for underwriting">
    Once all required data is in place, submit the application via `submitAcceptorApplication`. See [Submit an application](/acquiring/boarding/acceptor-applications/submit-application).
  </Step>

  <Step title="Complete boarding">
    After underwriting approval, proceed to account creation and boarding to enable the acceptor to begin processing transactions.
