Hi Nettie, We file our PTRS in a three ring binder alphabetically by buyer. They are grouped together by the Lister's fiscal year, April 2nd - April 1st. We archive the PTRS in a file box with the dates listed on the outside for retrieval. When a PTR comes into our office it is immediately filed into the three ring binder and a copy is given to the Listers. As far as charges, I charge a dollar a copy of a PTR. Take care and have a nice Easter. Linda:)
