Stop copying data between systems. Let them talk to each other.

As a business grows, it adds separate software for accounting, sales, shipping, marketplaces and customer relationships. When these systems are not connected, the same order, invoice or stock figure is entered several times by hand, which leads to errors, delays and reports that never quite match. Good integration is not about connecting everything to everything. It starts by deciding which system is the source of truth for each type of data, and then moves data only in the direction and at the frequency the business actually needs. Where it makes more sense to bring scattered data into one application, we also look at custom CRM and ERP software with you.

Every integration project begins with a data flow map. Together we document which systems will be connected, how fields map between them, whether data should move instantly via webhooks or in scheduled batches, and what should happen when a connection fails. The result is a written scope and a written quote, and the delivery date is set in the contract after scope approval.

We choose the architecture to fit the problem. A simple sync between two systems may only need a direct connection; once several systems are involved, we build a middleware layer that manages all flows in one place. We work with REST, GraphQL, SOAP, webhooks and SFTP or CSV exchanges, and we use message queues, automatic retries and idempotent processing so that records are not lost or duplicated. For legacy software without an API, we build secure bridges based on database access or file exchange. For shops with heavy product and order traffic, we often plan the integration together with the e-commerce platform itself.

Security is the most critical part of any integration. We use OAuth 2.0 and narrowly scoped API keys, and store secrets in an encrypted vault rather than in code. All traffic is encrypted with TLS, and personal data is masked in logs. Our work follows the OWASP API Security Top 10, we sign a GDPR-compliant data processing agreement, and on request the integration layer is hosted on servers inside the European Union. This matters in particular for companies selling to customers in Germany and the Netherlands.

Integrations are first tested against realistic scenarios in a staging environment and then rolled out to production step by step. On delivery, you receive an error monitoring dashboard, alerting, OpenAPI documentation and the complete source code. Throughout the project we send weekly progress reports. After launch, our maintenance service tracks version changes in third-party APIs and keeps your integrations up to date. If you want AI-assisted workflows on top of your integrations, we can plan them together with our AI automation service.
