I think it's necessary to make it into an electronic file for later inquiry. Don't look at a pile of lists and think it takes a lot of time to record them. It's actually very fast to actually record them. Otherwise, you won't be bothered by so many financial lists all day long! In this regard, you can consult the financial personnel. After the details are completed, the summary at the end of the month is just a matter of formula, which is very fast. Otherwise, if you need to check the original documents for any reason, you will feel more annoyed when faced with that pile of documents, and the boss will think that you have a problem with your ability because you can't provide the data right away. So I suggest you do it, it's not as troublesome as you think!
