A sales rep quotes a 500-unit order in the CRM. The unit price comes from a cost sheet someone exported from ERP last quarter, against a BOM engineering has revised twice since. The customer signs. Then purchasing finds out the current revision added a machined bracket and a tighter-tolerance bearing, and the margin on the deal is gone before the first part ships.
That isn’t a sales mistake. It’s what happens when CRM, PLM, and ERP are three vendors with three part numbers and a sync job between them. The quote line points at a description, not a released revision, so nothing tells the rep that the thing they priced no longer exists.
In N23D, a quote line is a link to a released part revision, the same part identity CAD, PLM, ERP, and MES already use. When engineering releases a new revision, every open quote still pointing at the old one is flagged with its cost change before anyone signs. It runs in one native Rust binary, local-first, with a permanent license.
One platform. Full digital thread. If a customer can sign a price for a revision engineering already retired, the thread between sales and the shop floor is broken.
