I need a better record-keeping system.
Actually, the big problem is that Steven does essentially all the work -- he has the inventory, he does the shipping, he does the invoicing, he collects and deposits the checks -- but he's not the guy who does the accounting at the end of the year. That's me and since he has all the records, life becomes entertaining. I know how to do the accounting, but it relies on being able to ask Steven for all of the right numbers.
This year, it's been an iterative process.
