We use Sage50 2016 and we are fairly new to it.  Our customers issue us a PO stating how much they approve that we spend on the Project, we then bill against this PO and when we get close we have to go back to the customer for a new PO to add to the old one and so on.  At this time we are using excel to track this but we were hoping to do it in Sage. 

I have gone through to see if I can do a project and a budget but it still doesn't warn when we go over the budget amount and I also have to print a Budget vs actual to see how far off we are. 

I should also mention that this is not a prepaid account by any means.

Hopefully I have explained this well, if anyone could help that would be great.
