The business app that replaces your spreadsheets.

Internal tool, client portal or B2B platform: which one do you need?

The internal tool serves your teams: it replaces shared spreadsheets and centralises a process you run every day. The client portal opens part of your data to your clients in self-service, which cuts down requests by email and phone. The B2B platform brings several companies onto one tool, each with its own roles and rules. If you are unsure, the scoping workshop settles it in half a day, and budgets per family are detailed on the pricing page.

What technologies do you use?

We code the majority of our applications in Next.js, React, Node and Postgres, with Tailwind on the front end and managed infrastructure for hosting. For mobile: PWA, React Native or native Swift / Kotlin depending on your performance constraints. We choose the stack that serves your project, not the other way around.

What is the difference between a business application and a SaaS?

A business application is built for a single organisation: it follows your processes, your roles and your business rules, and you own it. A SaaS is a multi-tenant product sold by subscription to many customers, with self-service billing and onboarding. And if your need is mainly to present your business, a showcase site is what you are looking for.

How are authentication and security handled?

We integrate proven solutions: SSO Google/Microsoft/Apple, 2FA, OAuth, JWT, and granular role-based permissions. Full GDPR compliance, data encryption, audit trails. We can target SOC 2 Type II if your market requires it.

Does the code truly belong to me?

Yes, 100%. No vendor lock-in, no proprietary platform: you receive the complete source code in your own repository, with documentation, infrastructure as code and CI/CD pipelines. From there, either your teams take over, or we keep evolving the tool through our Maintenance & Growth service.

How much does a custom business application cost?

An internal tool with a defined scope starts around €15,000. A client portal generally sits between €20,000 and €40,000, depending on the number of profiles and integrations. A multi-party B2B platform goes beyond €50,000 because data isolation and cross-organisation workflows weigh heavily on design. The breakdown of packages and budgets is on the dedicated page, and the final quote comes out of the scoping workshop.

Can we keep our current tools rather than replace everything?

Yes, and that is the most common case. A business application is not meant to replace your accounting, your CRM or your ERP: it fills the gap between them, the one your teams currently plug with a spreadsheet. We connect to what exists through APIs or scheduled imports, and we migrate only the data the tool actually needs.

What happens if the person who built the tool leaves?

That is the main risk of a custom tool, and it is handled through documentation and code ownership, not trust. You get the source code on your own repository, the infrastructure described as configuration files, the deployment procedures and up-to-date technical documentation. Any competent team can pick the project up, whether yours or ours through the Maintenance & Growth offer.
