Assigning extra costs to a job

I am new to epicor and my internal people can not help me. I would like to assign costs ( hotel, travel meals) to specific jobs. Can this be done without using a PO?
I would greatly appreciate any help I could get. I know this is basic, but I’m stumped. We are using version 9.

Check out Job Adjustment.

Adding cost to a job is done by adding a material.
Select the miscellaneous charge.
When you save the record the cost will be added to the job.

Using AP Invoice you add a job charge that you can add the cost to the job and also add the material from invoice entry.

Hope this helps.
