Build in Sprints
Two-week sprints with working demos. You see the vendor onboarding flow, checkout, and admin panel long before launch day.
Scale & Hand Off
Load testing, AWS or GCP deployment, runbooks, and training. Your team runs the platform. We stay on for 30 days post-launch.

FAQ
Quick answers.
When does a custom platform make sense vs Shopify?
Shopify when you need speed to market. Custom platform when you need multi-vendor logic, deep B2B workflows, or business rules a hosted platform can't support.
What tech stack do you use?
Next.js 15, Node.js, PostgreSQL, Redis, AWS or GCP, Stripe. We pick boring, proven technology. You don't need exotic infrastructure for most platforms.
How do you handle vendor payouts?
Stripe Connect for most marketplaces. Net-X payout schedules, automated commission splits, 1099 reporting. We've built this for platforms with thousands of vendors.
Do you support multiple currencies and regions?
Yes. Multi-currency checkout, regional pricing, local payment methods (SEPA, BACS, etc.), and Avalara for tax compliance. We've deployed across US, EU, and APAC.
