I have clients that are start ups, so may only need certain services in the early days. It would be helpful to be able to list other services and their costs so that clients know in advance what fees are.
You could have a commited fees section and then an FYI page for example so that clients have this as a reference point. Otherwise they wont know the price of other services without having to ask each time.
Thanks for the request - this feels like a nice feature to add the proposal content, perhaps a "Full list of services for reference" section. No plans right now but i'll keep track of the votes here to gauge priority.
