multiple templates on pdf

hello everyone, I am new to adobe and I am wondering if anyone could point me in the right direction. I run an auto repair shop and we use a system called tracs to create invoices and handle info etc. We have also picked up fleets of vehicles that require us to fill out separate paperwork for repairs and parts being used. I was wondering if there is anyway to create multiple templates of the same paper that has been pre made and provided to us, filled out in an assortment of different repair possibility's  and combine those templates into a pdf to print instead of hand writing these papers. For example if a vehicle needs a front brake job and also needs a coolant flush could I pull up both of those premade templates and combine them on my pre made sheet that I have saved as a pdf and print with parts, labor, etc already being filled out. thank you in advance for any help in advance!
