Every sector speaks its own standards. MPBx translates each into the same structured, validated spec language, so buyers, suppliers, and agents can source precisely across electronics, energy, mobility, infrastructure, and regulated industries without learning thirteen different RFQ forms.
B2B online ordering is full of silent errors. Per the research that drives the Spec Puzzle: 33% of B2B online orders contain errors; electrical distribution alone loses ≥$2B/year to wrong parts; and 68% of buyers are discouraged from online ordering because they do not trust the spec match. The fix is not more chat, it is a visual, validated spec puzzle that replaces the lost “phone call to the CSR.”
MPBx enforces the spec before the RFQ is sent. Every vertical carries required matching axes, validators, and a deterministic PartSignature. Missing or mismatched specs are caught before money moves.
