I'm looking at using this for a home services business that would have a daily route, based on the patron and their address. Does this app have the capability to manage this? Also, if a patron buys a package that provides annual periodic service, such as lawn care, does this app allow for patrons to buy a package that includes this, but invoices/bills them at the time of service, rather than the full amount all at once? Finally, does it have the capability of doing "add-on" services? For example, if a person pays to have their lawn care performed, would they be able to "add-on" a leaf blowing or hedge trimming service also? Maybe even in some sort of upsell format?
