I'm offering a ReSelling Excel File for $8.00. The file (emailed to you) would include all the tabs and columns mentioned in this blog post as well as an additional Misc tab in case you have another venue of ReSelling that you do. It would require you to have a version of Excel on your computer. You would simply Save the file to your computer and it would be ready to use immediately.
As a disclosure statement, I'm not an accountant or a lawyer. This is a file that I use for my everyday ReSelling business.
