How saro Ships Your Ecommerce MVP.
Commerce Audit
We map your product catalog, pricing model, vendor structure, and payment requirements. We identify which features are MVP-critical and which are nice-to-haves for version two.
Platform Decision
We recommend the right architecture, such as headless Shopify, Medusa.js, or fully custom, based on your vendor model, product complexity, and traffic expectations.
Build Sprints
Two-week sprints. You see working storefront, checkout, and vendor features every 14 days. Your team tests it with real products before we ship the next sprint.
Launch & Handover
We deploy, migrate your existing product data if applicable, hand over the codebase, and provide 30 days of post-launch support. Zero lock-in.
Is This You?
Multi-Vendor Marketplace: Launched in 8 Weeks
A specialty goods marketplace founder came to saro after a Shopify agency told them their multi-vendor model was "not possible" with themes. We built a custom Medusa.js marketplace with Stripe Connect payouts and vendor dashboards in 8 weeks. 45 vendors onboarded in the first month.
View Case StudiesCommon Questions.
Can you build a marketplace with multi-vendor payouts?
We use Stripe Connect for marketplace payouts, where vendors receive funds directly with commissions split automatically. We've built this on 6 different marketplace products.
When does my ecommerce product need a custom build vs. Shopify?
When you need multi-vendor payouts, tiered B2B pricing, custom inventory logic, or AI-powered features that Shopify apps can't handle. We tell you honestly in the first call whether Shopify is the right answer for you.
Can you add AI product recommendations to an existing store?
Yes. We've added semantic AI search and recommendation engines to existing Shopify stores without a full rebuild. This typically takes 3–4 weeks as a standalone project.
How long does a custom marketplace MVP take to build?
8 weeks for a focused marketplace MVP including vendor onboarding, product listings, checkout, and Stripe Connect payouts. AI search, subscription commerce, and complex inventory add 2–4 weeks.
