When you create a package for 2 services, you need to define how many sessions of each service are in the package. This is not a logical thing for us. Clients should also be able to choose any combination they want, within the total number of sessions.

Maybe this should be converted to credits? Be able to purchase a number of credits, that allows you to book any service that is elligible in the credits.

By credit or deduct by actual purchased amount is much more real-life. For example, client purchased/pre-paid a total of $2000 worth of services. Each time they come in they choose how much they want to spend on whatever service they feel like (impulse purchase) at that time. Deduct the total amount for all the services they chose during that session (they might come in with friends), and SMS client what’s been spent and how much is left. Better still, the commission for each service chosen by the client should also be calculated so that the manager can pay the staff quickly.
