What OEM teams miss inside their EMS manufacturing quotes
Most OEM procurement teams compare EMS quotes by the bottom line. They evaluate three or mfour providers, negotiate the lowest number, and move forward.
The problem is not the negotiation. The problem is what the quote hides. Material markups embedded in line items. Overhead allocations with no traceable basis. Inventory liability terms buried in contract appendices. Labor rates benchmarked against nothing.
OEM companies overpay their contract manufacturers by 15-30% not because they failed to negotiate, but because they never had visibility into how the price was built.
How this gets fixed
Every engagement starts the same way: open the quote, open the contract, and find the gaps between what the OEM team sees and what the provider’s cost structure actually contains.
$850 million in identified savings
A $31 billion consumer electronics company was managing a global EMS supply base across 14 providers. Quotes arrived in different formats. Cost models did not exist. Contract terms varied by region with no standard accountability framework. Through RFP restructuring, cost modeling, provider benchmarking, and contract renegotiation, the program identified $850 million in recoverable cost – most of it hidden in material handling fees, inventory reserves, and overhead allocations the OEM team had never questioned.
$35 million in procurement cost reduction
A $700 million energy and industrial OEM was sourcing complex electromechanical assemblies through a single provider with no competitive benchmark. A full cost teardown of the quoting structure revealed margin stacking across three line-item categories. Restructuring the RFQ process and introducing should-cost models against the existing BOM recovered $35 million within the first contract cycle.
$11 million through provider realignment
A $135 million networking company had outgrown its primary EMS provider but had no evaluation framework for replacement. The engagement built a provider scorecard, ran a structured RFP across qualified candidates, and negotiated new contract terms with cost visibility requirements the previous relationship never included. Result: $11 million in annual savings with a provider better matched to the program’s volume and complexity.
$7 million by rebuilding the sourcing process
A $400 million automotive and renewables OEM was quoting new programs through an informal process with no cost model and no competitive structure. Building a repeatable RFQ framework with should-cost benchmarks and standardized provider evaluation criteria recovered $7 million on the first two programs through the new process.
200+ engagements. $5B+ in client value created. OEM companies from $1M to $80B+ in revenue.
Start here
Before a conversation makes sense, you need to know where your gaps are.
I wrote a self-assessment covering the 50 questions every OEM procurement and supply chain team should be able to answer about their EMS relationships – covering RFQ process, provider evaluation, contract terms, cost visibility, NPI governance, and geographic strategy.
If your team can answer all 50, you probably do not need outside help. If you cannot get past the first ten, that tells you something.
