My claims are based on the article published so it’s a matter of clipping it out immediately and putting it in a file. I usually fill in the claim form immediately as well, so there’s no need to scramble around trying to figure out which need to be submitted. At the end of the month, I just make sure the forms are properly filled and all the articles are accounted for before I fill in the total of claims and submit it.

The keys is “don’t be lazy”. ;P

It also helps to keep everything you need in one file.
