How do I make a ledger for my self-employment?
Yes, that works. Sure, an accounting system would be nice, but even a simple spreadsheet for your situation works (too). Yes, pencil and paper works too. For what it's worth, I found my son's simple tracking system when I helped him start his first lawn mowing business some 16 years ago. It's similar to what you have described. But notice we have a column for expenses. It's no surprise he's a also a CPA like his dad. He was not required to file his earnings with the IRS. Hence, it was pretty basic but got the job done.
