Overview

When your ERP, web shop, CRM and accounting system don't talk to each other, you get double work and errors. We build secure, well-documented APIs and integrations that make data flow automatically between your systems.

We develop REST and GraphQL APIs in .NET and Node.js, integrate with third-party services such as payment providers, carriers and business systems, and build microservices that scale as your business grows. Security, logging and monitoring are built in from the start.

What's included

  • REST & GraphQL

    Modern, versioned APIs that are easy to build on.

  • System integrations

    ERP, CRM, e-commerce, payments and shipping in one connected flow.

  • Automated data flows

    Orders, customers and stock synchronised without manual work.

  • Security & access control

    OAuth2, tokens, encryption and clear access control.

  • Documentation

    OpenAPI specifications so other teams and partners can use the API.

  • Monitoring & operations

    Logging, alerts and performance tracking in production.

Questions about this service

How much does a new website or app cost?

It depends on scope, features and integrations. After a free first meeting you receive a written quote with a fixed price or a clear cost ceiling – with no hidden fees.

How long does a project take?

A business website usually takes 4–6 weeks from kick-off to launch. Larger online stores, web applications and apps typically take a few months. You always get a timeline before we start.

What does your process look like?

We work in four steps: discovery, design, development and launch. You get clickable prototypes before we build, a demo every other week during development and one point of contact throughout.

Can I update the content myself?

Yes. We build with a user-friendly CMS such as Sanity or WordPress, so you can change copy, images, pages and blog posts yourself. We show you how it works at launch.

Do you help with SEO?

Yes, technical SEO is always included: fast load times, mobile optimisation, structured data, sitemaps and correct language handling. We also advise on content and keywords so the right customers find you on Google.
