Definition
A source of truth is the authoritative system or process responsible for a specific record and its updates.
Why this matters in your Manufacturer-to-Business project
Manufacturer commerce gets fragile when several systems can edit the same customer, product, price, inventory, quote, or order record without clear ownership.
In your manufacturer-to-business commerce project, a term like Source of Truth should be tied to a real workflow. The practical question is not whether the term appears in a vendor feature list. The question is which buyer path, internal handoff, system record, approval rule, or operating risk it affects for you.
During planning, translate this term into requirements, data ownership, test cases, launch boundaries, and support responsibilities. That keeps the conversation grounded in how your company actually sells, fulfills, and supports customers and dealers.
