LBS dealer network + ride-along assembly, how do you build ship-to-LBS in Magento?

Federal CPSC bike-assembly rules + brand warranty terms (Trek, Specialized, Cannondale) make ship-to-LBS the safe + legal path for full-build bikes. Customer doesn’t want to torque their own headset; the LBS gets a service-revenue moment; the brand keeps warranty coverage tight.

Magento setup:

• Dealer entity, custom EAV-backed model for LBS shops with name, address, geo-coordinates, services offered (assembly / fit / suspension service), in-store inventory level, photos, hours.
• Zip-code radius locator on PDP, customer enters zip, sees nearest 3-10 dealers with distance, ratings, services. Built with Magento + a Google Maps / Mapbox JS layer.
• Shipping rule that splits the order, full-build bikes ship to the chosen dealer, parts/accessories ship to home. Magento native multi-address checkout extended with custom logic.
• Dealer-portal extension, per-shop admin view showing inbound orders, customer pickup status, commission tracking. Built on top of Adobe Commerce B2B Companies or third-party (Aheadworks).
• Customer notifications, “arrived at dealer / assembly in progress / ready for pickup” emails. Triggered by dealer-side admin updates.

Time to ship: 4-8 weeks. Cost: $15k, $35k depending on dealer-portal sophistication. Single-brand stores can skip the portal and use Magento admin directly; multi-brand portals need the portal.
