Follow a real patio project through the whole system — you're Harborline Landscape Contractors (fictional). Every green-badged screen runs on the live engine; amber badges are roadmap, honestly labeled.
Your estimate says 460 sf of pavers, base gravel, bedding sand, edge restraint. One click sent it to four yards as a sealed quote request — nobody sees each other's numbers.
Three quoted, one declined "no stock." The cheapest looked great — until the flags: one yard quoted a substitute brand, another could only cover half.
Day three: a cut-waste miscount. The crew stalls at noon without more pavers and edging. You post an ⚡ Urgent Fill — need it by 12:00.
Watch what the ranking does: the cheapest yard ($443) can't deliver until 3 PM — greyed, ranked last. A closer yard attested stock on hand, committed 9:30 AM, added an honest $60 rush fee — it wins at $554. Speed beat price, on purpose, and the rush fee is its own line.
Seacoast Stoneworks is slow this week and posts 1,200 sf of Cambridge Onyx at $6.20 against a $6.50 regular price — their choice, their price, moving dead stock. First contractor to commit takes it.
Try it yourself: claim it. (If someone beat you to it, that's the point — first commit wins.)
A finished job: awarded on price, then the final invoice reconciled against the quote — on-time, in-full, and 7.1% under the old single-yard price. Quotes are promises; invoices are the truth, so the system scores itself on invoices.
Coming: the winning yard's truck on a map — pickup confirmed, ETA to your site, GPS-verified drop. (Design done; ships after the pilot proves the core.)
Coming: over-ordered two pallets? The yard offers a pickup-and-restock service on the same truck that delivers your next order — a second way yards win.
Coming: for jobs where YOU want maximum price pressure, flip one switch — every invited yard sees the current low price (never who), same rules for everyone, and may re-bid until the deadline. Sealed stays the default.
Coming: yards get posting logins, reservation windows on surplus claims, partial-claim splits, and a confirmation step. Today's surplus board is the working preview.
Everything green ran on the real engine with real math — sealed quoting, deadline discipline, honest rush fees, first-commit surplus, invoice truth. Everything amber is labeled, because a demo that lies to a yard owner would cost us the only thing that matters: trust.
