Thanks for reaching out to QuickBooks Desktop (QBDT) for a recommendation for an ERP system, Mbecker1. Let me also provide details for third-party software to connect with QBDT.
There are third-party software options available to facilitate connections between QBDT for small IT companies. Consider using a third-party application to centrally manage clients' data, accounting information, and other critical business operations. I recommend exploring the third-party App connector to integrate QBDT: Apps for QuickBooks Desktop.
I'd also like to add that if you want to customize your email templates, we have a guide that'll help you with the process: Create custom email templates in QuickBooks Desktop.
If you have further questions or need recommendations for the ERP system, feel free to post here again. I'm happy to offer additional assistance. Take care and have a good one.
