Hi there johndegbile,
We'd be sad to see you go, but you need to only have the services needed to run your business. QuickBooks Online has the ability to export information in order for you to have some information saved for records. I can provide some information about exporting data.
in order to export information from QuickBooks Online, I recommend following the steps in this article. There is a list of different types of information and lists that can be exported, as well as the steps to do so. Attachments are one of those things that can be exported.
If you have any other questions, feel free to reach out here.
