Hi there, Adam. Integration between Square or Stripe and QuickBooks Online is typically free if direct connectivity is supported. You can check if these services appear under the Bank Feeds section or within the QuickBooks Online apps marketplace. If the connection is supported, you can sync without any additional fees.
However, in cases where direct connectivity is not available, you may need to use third-party connector applications. These connectors are separate from QuickBooks and are an additional cost if required for integration.
You can revisit this thread if you have follow-up questions.
