We think and need in Work Order Module to manage our work orders.
Fields like Work Name, Work Detail, Problem / Solution, Start Time, End Time, Asigned to, Due Date, Materials List, Estimate Cost and others like that can be very useful.
We are working with Some Apps to do our work but the very important think will be Make a Work Order, and when finished Invoice it from the invoice module.
We use the CRM sales orders and are able to customize the sales order module to work as work orders including naming the module, creating templates and adding fields. We are just now starting to transition to using ZB for this and for estimates. We too are a field service company. It would be nice to at least change the name of the section in ZB to "Work Orders".
