"Paperwork" describes forms, applications, records, contracts, and other documents which a person has to deal with.
We often use the word like this:
You wouldn't believe how much paperwork I had to fill out in order to get them shipped here.
I thought about doing it myself, but then I realized that there was way too much paperwork involved and so I got an accountant.
In other words, "paperwork" is something that people often complain about.
