An ecommerce site costs between $8,000 and $150,000 to build in the US, and the platform decides more of that than the design does. A Shopify store with a customised theme runs $8,000 to $35,000. A Shopify Plus or BigCommerce build with integrations lands between $40,000 and $90,000. Adobe Commerce starts higher and adds infrastructure cost, which is why it only makes sense with catalog or B2B complexity to justify it.

Platform fees, payment processing at 2 to 3 percent, apps commonly $100 to $600 a month, and maintenance. Adobe Commerce adds hosting and patching on top.
Shopify unless you have complex B2B rules, unusual catalog structures, or a genuine reason to control hosting. The staffing cost difference is real and persistent.
Four to ten weeks on Shopify, three to six months on Adobe Commerce, with catalog data preparation usually the critical path.
