If you run a recurring coaching program. Bill every 4 weeks instead of every month. There are 13 four-week cycles in a year. Compared to 12 monthly cycles. That means you collect one extra payment per client with no extra work. Clients barely notice the difference. "Every 4 weeks" feels the same as monthly. But it creates an 8.3% increase in revenue. And because your costs don't go up, most of that goes straight to profit. Example: Say you have 600 clients paying $100 per month. That's $1,200 per year each. At a 30% margin, you make $360 in profit per client. Total: $720,000 in revenue. $216,000 in profit. Now bill $100 every 4 weeks instead. Clients pay 13 times a year. ~$1,300 each. Revenue climbs to $780,000. That extra $60,000 costs you almost nothing to deliver — you're already doing the work. So most of it drops straight to profit. Profit jumps from $216,000 to ~$276,000. Same clients. Same work. 28% more profit. Proof: We've done this with over 1,000 recurring clients across various programs. The result? Virtually zero difference in retention. Same clients staying. More revenue collected. More profit kept.
