Thanks for dropping by the Community, @FarmerBonestorm.
QuickBooks Online (QBO) currently doesn't support the PayAnywhere app integration. That said, I highly suggest contacting third-party app support again. Their developer can check and assist you further with the integration.
For tips and other resources, you can also visit our website for future reference: Self-help articles.
Please let me know if you have any other questions or concerns. I want to make sure everything is taken care of for you. I'll be here to help. Have a wonderful day!
