Hi IPCQTam,
Thanks for the response.
You might want to look at Sales (Customer Detail) Report, this report displays the invoice line items, including quantity sold, for all sales to the selected customers within the period range. You may modify the columns and the job number is also included on the option from show/hide tab. You may refer to the sample screenshot I have provided below. Please note that important details are hidden in this sample.

You may also have a look at this help article, sales reports that will give you all detailed information and available reports options.
If you need further help, don't hesitate to start a new post and we'll be happy to assist.
