Yield Management Corporation was founded in 2002 as a supplier to the Wire & Cable Industry providing machinery, parts and quality control devices designed and developed in YMC’s Engineering Group. As our reputation as a “solutions provider” has grown, we have expanded our business to include Municipal Water controls and Commercial Vehicle Inspections. Our goal to provide “value added solutions” has contributed to our growth and reach into these varying industries.

Our entry into Commercial Vehicle Inspections is the result of our relationship with Applus Technologies. YMC began our relationship rebuilding Zero Air Generators for the Massachusetts and Rhode Island Inspection Programs in 2005. We have expanded our relationship as a supplier offering unique solutions to the consumables portion of the Massachusetts Vehicle Inspection Program.

When the administration of the Massachusetts program was awarded to SGS Testcom, Yield Management Corporation was offered to apply for a Mobile Inspection License and formed a Commercial Inspection division, license # PB050147. We have been in operation since October 2009. We continue to supply consumables to SGS Testcom as we did for Applus Technologies.

Our approach to our commercial clients is, first and foremost, to operate safely and respect our client’s facility as a welcomed guest. 

Our licensed inspectors work with the business owners and maintenance managers to insure that all vehicles meet the Massachusetts and Federal regulations. When noncompliance issues are found, they can often be corrected at the time of the inspection. Our goal is to make the inspection process as convenient and efficient as possible to our clients.

We offer flexible inspection hours including nights and weekends to minimize impact on our client’s operation.
