Welcome to the forum!
It sounds as though you are off to a good start. I use spreadsheets for a whole lot of things I have my shop sheet, which gets updated whenever I accept shops, request shops, report shops, get paid for shops, etc. It is the heart of my business. Mert has included a link to a basic one on the New Mystery Shopper section. I also have a spreadsheet of the companies I have signed up with that includes the company name, URL for their login page, my user name, password, date I originally registered with them and then any notes. And I have a spreadsheet of 'who shops whom' because even companies who currently don't have shops in my area shop clients who may eventually be in my area because we get new franchises here every year.
