I designed the spreadsheet for a simple business that does 355 transactions a year or less. If you do more transactions, it shouldn’t be difficult to expand it. However, try using a more powerful tool, such as GnuCash, or one of the commercial accounting software packages.
Expense categories mirror those on Form 1040 Schedule C.
You’ll find instructions under the “Help” tab. Also, please keep your data secure.
