Building Solid Bundles, a Shopify app for stores whose 3PL has to actually pick what the bundle contains. First bet in a portfolio of small B2B apps. Day job in software, shipping nights and weekends from Germany.
Shopify bundles and quantity breaks that put real component SKUs in every order, so 3PLs and warehouses pick without translation tables. Built on Shopify's Cart Transform API. Flat $29/mo. Currently in App Store review, onboarding beta merchants with 3PL setups.
