Set Up a Financial Planning Process for Going Freelance

The financial chaos most freelancers experience in the first year is almost entirely preventable with three systems: a bank account structure that separates money properly, a tax set-aside rule applied from the first invoice, and a monthly review that takes twenty minutes. Most people set these up after the first year has been messy. This sets them up before the mess starts.

**Set up the essential financial systems:**
1. Design the bank account structure: the minimum number of accounts needed and what each one is for
2. Describe the tax set-aside rule: how to calculate the right percentage to hold back from each payment received
3. Build the monthly financial review: a 20-minute monthly habit that keeps the finances visible and under control
4. Advise on invoicing: what a professional invoice must contain and the single most important thing to do to get paid on time
5. Explain the point at which an accountant becomes worth the investment for a freelancer
