ZAM_BRI- I don't know how effective this may be but some points to include in the buy-off procedure: Before submitting the PO for the stencil you may also want to do a CAD to Stencil comparison to verify correct apertures.There are SW packages and companies that do this regularly. You also need to define the apertures - laser cut, Trapezoidal, polished...... Also define frame - frameless, Solid, hollow. Define the fiducial information-etched on, dot, or hole.

You can also refer to IPC 7525 Stencil Design guidelines for additional help.
