It would be awesome if the client billing feature included the ability to customize different client billing options.
- Hosting = $30 / month
- Hosting + Unlimited Minor Changes = $100 /month
- Hosting + Changes + Monthly Design Services = $250 /month
A feature like this would help freelancers, agencies, and studios profit more, manage their business better, and give clients options that are helpful to them.
I'd would definitely pay more more for a feature like in the future.
