Income and expenses spreadsheet

Thank you SGIII for responding. I’m viewing MacMostLive: Building a Basic Business Spreadsheet. I can’t get the formulas to work. I have used QuickBooks for years, inputting the numbers myself into a PC because downloaded numbers required so many changes it was easier to enter each transaction myself. Last year I decided to use QuickBooks online. Another nightmare. And I have reached out to QuickBooks professionals and get no response. QuickBooks refused to help me because I am using an IPad instead of a PC. My business is a one pony operation. I vend at trade shows all over the USA and run my entire business using my iPad, as do many other vendors. All I need is a simple spreadsheet to daily enter income and expenses and add them up to give to my tax preparer. The spreadsheet on MacMostLive seems easy enough but I can’t get the formulas to work. I’d gladly pay for a Numbers compatible spreadsheet. Do you have any ideas for me? Thank you kindly.
