Complete eCommerce Systems, Built Front End to Back End
We design, build and run the entire commerce stack — a fast custom storefront, a backend that scales, and every integration in between.
Trusted by commerce teams across Europe
One Team for the Whole Commerce Stack
Custom Storefront Development
Pixel-perfect React and Next.js storefronts built for speed. Server-side rendering, Core Web Vitals in the green, and a conversion-first UX on every device.
Headless Commerce Architecture
A decoupled front end on a composable back end. Swap any layer — CMS, search, payments, ERP — without rebuilding the store from scratch.
Backend & Commerce API
Catalog, cart, orders, inventory and pricing engines behind a clean REST and GraphQL API — built to take Black Friday traffic without blinking.
Payments & Checkout
One-page checkout with Stripe, Adyen, PayPal and local providers. PCI-compliant, fraud-screened, and tuned to cut cart abandonment.
ERP, PIM & CRM Integrations
Two-way sync with SAP, NetSuite, Dynamics, Salesforce and your WMS. Orders, stock and product data stay consistent across every system.
Migration & Managed Support
Move off Magento, Shopify or a legacy build with no lost SKUs and no SEO drop — then keep it running with 24/7 monitoring and SLA-backed support.
From Scope to Launch in Weeks, Not Quarters
A fixed four-step delivery model. You get a working staging environment early and see real progress every sprint — no six-month black box.
- Technical discovery and scoping
- Architecture and UX blueprint
- Front end and back end built in parallel
- Migration, load testing and launch
Why Teams Choose Nexum Forge
You are not renting hands. You get a senior product team that owns the entire stack and the numbers it moves.
- Senior engineers only — no junior padding
- Full ownership: front end, back end, DevOps and QA
- Composable architecture, and the code is yours
- Sub-second pages and green Core Web Vitals
- Fixed-scope launch, then SLA-backed support
Nexum Forge rebuilt our storefront and backend in four months — and our conversion rate went up 38%.
We came off a legacy build where a category page took nine seconds to load. Nexum Forge re-architected the whole thing — headless front end, a new commerce API, live ERP sync — and migrated 40,000 SKUs without losing a single URL. Peak season ran without one incident.

Frequently Asked Questions
The whole system. Storefront, commerce back end, integrations, infrastructure and QA. You get one team and one point of accountability instead of stitching three vendors together.
Next.js, React and TypeScript on the front end; Node.js, NestJS, PHP 8 or .NET on the back end; commercetools, Medusa, Shopify or a custom commerce core, depending on your catalog and rules. Everything runs on AWS or your own cloud.
Yes. Repositories, infrastructure-as-code and documentation are yours from the first commit. No licence lock-in and no proprietary black boxes.
A focused replatform typically runs 10 to 16 weeks. Large B2B systems with deep ERP integration run four to six months. You see a working staging environment inside the first three weeks.
Yes. We have moved catalogs of more than a million SKUs with a full 301 map, so rankings and traffic hold. Product, customer and order history all come across.
We load-test against your projected peak times three, run game days before the season, and put autoscaling, queueing and circuit breakers in front of checkout. We are on call through the peak window.
Fixed-scope builds start around €45,000. A dedicated senior pod is billed monthly. Managed support is a fixed monthly SLA fee. You get a written estimate after the discovery call.
You move onto an SLA-backed support agreement: 24/7 monitoring, a 15-minute P1 response, weekly releases and a shared roadmap. Same engineers who built it.
