HI MahGah, thank you for your reply, and sorry for all the time spent to reply to you.
In fact, i'm not sure that you could get my point.
I'm talking about a physical progress of a task, this means that, for example, If I have 100 meters of cable to install and only installed 50 meters, this means that I'm having 50% of progress. independently of the time spend to do this work.
this 50% are the real value of my work from which I can calculate my earned value and get deeper and exact financial state.
The %Completion of task based on time spend versus time planned is not representative of the work done.
I think that without this really important "Physical Percent Progress", it would be impossible to get the real financial state of a project, but also impossible to forecast the remaining work, in order to invoice customer in case of more work needed, before the end of the project.
If with a customer I'm planning 100 hours of work, and spend 50 % of work in 50 hours then all is ok.
But in case of I did 50% of a work in 70 hours, this almost means that I will need 70 hours more to complete that job.
Analysis : I have to do some training :) to be best in my work, or, there is more work than expected, and I have to invoice customer for that. If he doesn't want to pay more, then I have to stop now before loosing time and money.
Another advantage of this is to help for a strong forecast, improve the invoicing system, detect in advance any defect from employee, and show to customer that we are focusing on the job and we want to make sure to deliver the project in best conditions.
It is always a bad thing to invoice customer after completing a job and telling him that we worked more than expected. there is a high risk to loose him.
conclusion :
I need to implement such behavior, in financial aspect.
In another thread, you get exactly my point and you provided me the DYCE Job Billing app, that is nearly what I need in order to connect Job and sales order, and im still study it.
I would like to improve that by adding this "Physical percent" exactly as shown here :

Hope I've been clear enough, and thank you to you and and for all for any good idea.
