The sourcing platform buyers use to find verified turnkey contract manufacturers for electro-mechanical box builds and system integration. Free to start.
Box build is where contract manufacturing gets complex, combining electronics, mechanical structure, firmware, and packaging into a tested, labeled, production-ready product. Finding a supplier who can own that entire process rather than just individual steps requires a sourcing platform that goes beyond a capability list. TandemOne profiles verified box build and system integration suppliers by electro-mechanical assembly experience, test capability, firmware integration, and supply chain management depth so buyers can find a genuine turnkey manufacturing partner.
PCBA integration, mechanical assembly, firmware flashing, calibration, regulatory marking, and packaging are captured as a combined capability, not a list of separate services.
Functional test development capability, end-of-line test coverage, and traceability systems are profiled so you can assess whether a supplier's quality infrastructure matches your product's complexity.
BOM complexity, firmware requirements, test plan availability, regulatory requirements, and production volume go into one inquiry so suppliers can assess fit and respond with realistic program proposals.
TandemOne is free for every buyer.
OEMs and product companies launching complex electro-mechanical products who want to outsource the complete manufacturing process to a single accountable partner, reducing multi-supplier coordination complexity and freeing internal teams to focus on product development and commercial growth.
