If you've set aside your hour this week to look at your money, here's what you want to do:
Review client payments
Download transactions into your accounting software (e.g. Quickbooks)
(You will need to have set up your accounting software with your Chart of Accounts so that you can categorize your spending and income appropriately.)
Record the checks you wrote
If you are feeling panicky:
Hire a book-keeper to set up your system! They don't cost much and can get you started with no fuss. Many accountants have book-keepers on staff to work with you, or can recommend someone.
