I run a coaching business with similar booking volume to what you're describing, so I understand the financial considerations well. Pricing structures can definitely make a difference when you're just starting out. What works best really depends on your growth projections and whether you value predictability in expenses. I personally prefer the subscription model because my business expenses are more predictable month to month, which makes accounting easier. With commission-based systems, some months could be significantly higher if I have a good month for bookings, which creates budgeting headaches. I integrated Online booking service for clients into my workflow and their straightforward monthly pricing meant I could forecast expenses accurately. No hidden fees, no surprise charges. The service includes client reminders, payment processing, and calendar synchronization, so I'm not having to pay separately for those features. For small practices like ours, simplicity in pricing actually matters more than saving a few dollars monthly.
