How do business owners handle subcontracting agreements when the subcontractor may work on several different projects for several different clients of the Contractor, simultaneously or over a period of years?  The answer is to tweak the standard Subcontractor Agreement to make it a “master” agreement, so that it covers not just the first project, but future projects as well.  Here is some language I add:

WHEREAS, Contractor and Subcontractor (the “Parties”) agree that for mutually agreed upon Clients, Contractor may choose to utilize Subcontractor with respect to certain Services specifically set forth herein and in any Statement of Work attached to this Agreement;

WHEREAS, Contractor and Subcontractor desire to enter into a master agreement that sets forth the terms and conditions pursuant to which Contractor and Subcontractor shall, for mutually agreed upon Clients, provide certain Services to one or more of Contractor’s clients;

Statement of Work.  The parties will memorialize the Subcontractor work in the attached Statement of Work (a “Statement of Work” or “SOW”) that is entered into between the parties and is incorporated into and made a part of this Agreement.  Contractor may issue a purchase order (“Purchase Order”) with the mutually agreed upon and signed Statement of Work attached for all work to be performed by Subcontractor under this Agreement.  A SOW, if and only to the extent then followed by a Purchase Order, constitutes the only authorization for Subcontractor to take any action that will result in any expense to Contractor.  Any SOW shall be substantially in the form of the representative SOW attached as Exhibit A to this Agreement and shall reference this Agreement and shall specify: (a) the overall project description and Subcontractor’s requirements for the services; (b) the services to be performed, including materials to be provided, by Subcontractor; (c) the charges or billing rates and payment milestones for the services performed by Subcontractor; (d) the location(s) where the services are to be performed;  (e) the acceptance criteria and warranty provisions for such work; (f) anticipated start and finish dates; and (g) any other information and/or associated terms and conditions that may be required by the circumstances of a particular Statement of Work.
