US kidswear brand Lola + The Boys grew domestically, yet international visitors abandoned orders because shipping, duties and delivery were uncertain. A Shopify case study reports that nine months after adopting Managed Markets, international sales grew 66%, international conversion improved 18%, international share of revenue quadrupled, and support time on overseas orders fell by 16 hours per month. The mechanism is not simply more advertising: buyers see landed cost, delivery timing, local currency and payment options before checkout while duties and fulfillment are centralized. Costs and risks include platform and service fees, international returns, currency movement and compliance. The vendor-published case does not disclose absolute revenue or profit.
