Hi All, I have decided to go with OpenERP to implement a solution for our company. The HR and Warehouse modules are OK for my solution but i have some concerns about project management module wheter i can success to do with openerp. The flow which i want to implement as seen as below,

1. Create a contract with a customer which includes the unit service prices and person/day pricing information.(ie. 1 meter of welding costs 10 dollar, 1 ultrasonic film costs 20 dollar, 1welding engineer per day 300 dollar)
   1. After contract approved, need to set engineer status as working or something( i think this can be done in HR module) and ship the equipments. 3.When the project starts, need to create work order and after work order finished need to fill which services have been performed.
   2. At the end of the month need to calculate the payment which the customer needs to pay.

Which way should i follow. Do you think is it a goog way to start with OpenErp? Which modules fits my needs?

Regards
