Production-grade Web & Blockchain engineering — no templates, no shortcuts.
Multi-vendor marketplaces fail when built like single-vendor stores. We engineer marketplace platforms with proper seller isolation, automated payment splitting, and the operational infrastructure to scale to thousands of vendors without rewrites.
What this means
A two-sided marketplace isn't a Shopify store with extra plugins. It requires multi-tenant data architecture, per-seller permission systems, automated payment splitting, independent payout flows, and a platform admin layer that sits above everything — all working reliably under real transaction volume.
Most agencies build the buyer-facing storefront well. They underestimate the seller side and the financial infrastructure — which is where marketplaces break at scale.
Nextelligentia has built marketplaces across retail, services, and digital goods. We architect for the two-sided complexity from day one so you don't pay to rebuild it at 1,000 sellers.

Book intro callHow it works
Every phase has a defined output and your sign-off before we proceed. Getting marketplace architecture right at the start saves months of rework later.
Everything in-house. Architecture, design, development, and QA — same team from kickoff to launch.
We map your buyer and seller journeys, define commission structures, and identify compliance requirements before any architecture decisions are made.
Multi-tenancy design, payment infrastructure, third-party integrations, and a fixed price in writing before a single line of code.
Buyer-facing storefront, seller dashboard, and admin panel — designed as three distinct experiences that work as one coherent product.
Payment splitting, order flows, seller APIs — built and integration-tested with regular check-ins. You always know where things stand.
Load testing, payment flow QA, fraud prevention review, and a staged launch so your marketplace goes live without surprises.
Ongoing marketplace retainer
New seller categories, performance improvements, payment provider updates, fraud tooling, and feature expansion — we stay plugged into your marketplace as it grows.
