For two years I ran client work, content, and invoices out of five different apps — Trello for clients, Google Sheets for money, Notes app for content ideas. Nothing talked to each other and I kept dropping balls.

What fixed it wasn't a fancier tool, it was cutting down to 3 boards in one place:

1. Clients — every active/prospective client, their status, and next action. If it's not in this board, it doesn't exist.

2. Content — a rolling 2-week calendar so I'm never scrambling the night before a post is due.

3. Finance — every invoice and payment logged the day it happens, not at tax time.

The trick is keeping each board dead simple — 5-6 fields max. The moment a system takes longer to update than the task itself, you'll abandon it in a week.

I turned this into a Notion template (Freelancer OS) if anyone wants the exact setup instead of building from scratch — but honestly, even just sketching these 3 boards yourself will fix 80% of the chaos.
