Hello @handsonapproache,
We have a separate forum that can better explain how you can integrate a customer relationship management program to QuickBooks.
First off, @plung is correct. In addition, I'd also recommend visiting our Intuit Developer Support and start a thread with the same question you posted. From there, someone will help and guide you with how you can integrate a customer relationship program.
In case you need some related articles in managing your account, you can always visit our Help Articles hub for reference.
Let me know how it goes in the comment section down below. I'll be always around ready to help.
