 Overview
 	V7 contracts did this:
-		Limit rates that can be selected
+		Limit rates that can be selected to only those selected in contract and which are set to "Contract rate" in themselves
+		or just offer those contract rates in addition to regular rates
 		apply a discount to all parts selected for that contract in effect

 Contracts are never tied directly to an object they affect other than the Customer or Headoffice with a foreign key link
 	workorders should never be reliant on the existance of a contract but rather just have a contract applied to them for example

+Contracts *are* tied to objects that use them like Client, HeadOffice, Unit

+Which contract to apply
+	In order of least to most specific: Headoffice, Customer, Unit

 Need rates picklists to support criteria of contract rates only for selection
 	perhaps server supplies which contract id is in effect and limit to rates

 	Contract needs selectable tags for any aspect to apply
 	Discount / markup etc parts / rates
 		So, in practice like in v7 you set a discount for all parts but then you can also on the same line restrict it to specific part tags and select tags right there
-		The server then applies the discount based on whether the parts are tagged or not if that's the case in it's bizactions
