It is very nice to present the latest product - appointments system.
This is a modification to make appointments - nail salons, beauticians, hairdressers, mechanical plants (car repair) and many more.
Extensive capabilities and SMS notifications (you must have an account on twilio.com) will not let you miss the visit.
Transparent panel for administration and plant owners (topic authors), the ability to add services with prices, employees can choose their days off. Customers can arrange according to the available criteria. Employees can mark completed orders as done and many more.
There is special option to select one custom profile field - it would become a "work place" field.
This whole system it's a combination of three mods and apps (appointments system, special profile field and business hours).
If you have questions, I invite you to PM.
