Commerce platforms (B2B/B2C)
We implement modern commerce when off-the-shelf SaaS stops matching your processes: B2B with contract pricing, complex promotions, ERP/PIM/WMS integrations, and owned storefronts. We design a modular architecture — orders, catalog, payments, and logistics connected through APIs. MedusaJS is our primary headless commerce backend — we still recommend a stack aligned with your scale, team, and roadmap.

How does our cooperation look like?
A transparent process that leads from idea to finished product
- Step 01
Discovery & strategy
We analyze sales models (B2B/B2C), channels, compliance (GDPR, Omnibus), and limits of current tools. We define MVP scope and critical integrations.
- Step 02
Architecture & stack
We design services, APIs, and data flows. We pick the engine (often MedusaJS), storefront, and integration layer.
- Step 03
Commerce core & catalog
Products, variants, B2B price lists, promotions, inventory — foundations for automation and scale.
- Step 04
Storefront & UX
Fast frontends (e.g. Next.js), CRO, accessibility, analytics, and conversion testing.
- Step 05
ERP/PIM/WMS integrations
Stock, orders, accounts, and pricing sync. Queues, monitoring, retries, and event audit trails.
- Step 06
Launch & evolution
Load testing, rollout, SLA, and backlog. Support for campaigns and peak traffic.
