Hello! Thanks for reaching out with your question about integrating your property management workflow with QuickBooks.
The short answer to your main question is, it is possible to integrate and automate processes with QuickBooks using an API. I recommend consulting your technical consultant with Intuit Developer support to further develop this integration.
Intuit Developer Support: This is the community and help portal for developers building with QuickBooks APIs. They can answer specific questions about which API calls to use for transactions, how to handle batch processing for all 70 properties, and any technical limitations you may face.
They'll be able to get right into the technical weeds of the API, which will ensure your custom solution for Otonom, CSV automation, and Law 25 compliance is built correctly from the ground up.
Let us know if you have further concerns with QuickBooks Online. We're always ready to assist.
