  2. Choose the Gear icon > Company Settings.
  3. On the left menu, click Payments.

  6. Confirm the correct Merchant account is listed.
  7. Click the Link account button.
  • Depending on the specific type of merchant account you have, you may not be able to link it from the website.  In that case, you'll need to call Payment Services support at 800.558.9558 to complete the process.
