Flat fee practices, learning as I go!
When I started my QB based business, I was not sure how long it would take to various things so I billed by the hour. A recent 2023 virtual seminar was pretty good and advocated for flat fee billing, as when you get efficient and skilled, you can make more money and the customers can know what its going to cost every month.
Just sharing that I got a new client and their prior bookkeeper (who was also QB certified) and when I got into the books they were not in good shape. I should have bid this by the hour to get the books cleaned during introduction period, then a flat fee. Its been a bit of mess cleaning up as a sales feed program had loading errors and missing invoices and payments so the A/R aging showed where the bodies were buried.
Hope this helps, I learned the hard way.
