Is there a job card system that I can integrate with Quickbooks for my manufacturing business that works on customised orders?

Hello, info1254.

There are apps in QuickBooks that provides order management for manufacturing business. You can find the applications by following these steps:

1. Click this link QuickBooks Online Apps and Add-Ons. 
2. Go to the Inventory section.
3. Select an app card by clicking the Learn more link. This will direct you to the app's website where you'll find things you need to know about the app, the contact details, as well as the app's support information.

To integrate the app, I'd recommend contacting their support team for the instructions.

Please let me know if you have any follow-up questions or other concerns. I'm always here to help.
