B&Q Marketplace is gated at the category level and enforced at the data level. It runs on Mirakl, so product data and offer data are separate jobs: one leaf category per offer, every mandatory attribute filled, an unrecognised GTIN rejected outright. Clear that and your range sits beside B&Q’s own. It is a curated channel, not a volume one.
- Application, category approval, and Mirakl product and offer feeds built so nothing is rejected at the first import.
- Pricing, stock and delivery promise set against the B&Q buy box, and a straight answer on whether Marketplace Click and Collect is worth the ship-to-store work.
- Sponsored placement and promotions where B&Q offers them, funded only where the category traffic justifies it.
- The seller scorecard treated as an operational risk: acceptance rate against B&Q’s order window, on-time dispatch, cancellations and message response.
