Odoo is the world's easiest all-in-one management software. It includes hundreds of business apps:
CRM | e-Commerce | Accounting | Inventory | PoS | Project management | MRP | etc.
Interesting problem with the Product Cost Structure report but I'm not sure if it's a bug or a configuration problem.
I setup a Work Center with everything set to 1 (Efficiency, capacity, time for 1 cycle) Cost per hour I set at 18.32 and Cost per cycle as 4.40
I setup a Routing which uses this Work Center for a number of work steps, Number of Cycles and Number of Hours are identical (because 1 cycle takes 1 hour)
