How data engineering differs from regular software development
This isn't about an application people interact with directly. It's about the reliable flow of data between systems: from inventory management, CRM, production equipment, or external sources into a central data warehouse, prepared for analysis and reporting. A data engineering agency builds these pipelines, models the data structure inside the warehouse, and makes sure the numbers in your dashboard are actually correct, even as source systems change.
What matters when building data infrastructure
Data quality is where most projects fail, not the technology. A good agency builds in checks that catch bad or missing data before it flows into reports and drives the wrong decisions.
The choice of tools, whether that's Snowflake, BigQuery, or a self-hosted warehouse, dbt for transformation, Kafka for real-time streams, should fit your data volume and budget, not the biggest name on the market. Most mid-sized companies get by fine with a much simpler stack than the big cloud providers like to sell.
Documentation determines how well this ages. Without documented data models, every future change turns into detective work. And settle early who's responsible for ongoing maintenance after the project ends. Data pipelines need continuous attention, not a one-time project with a final report.
What building data infrastructure costs
€130 to €190 per hour is standard for specialized data engineering agencies. A single pipeline connecting two to three source systems costs €15,000 to €40,000. A complete data warehouse with multiple sources and BI dashboards runs €40,000 to €120,000. Ongoing operations and further development cost extra, often as a monthly retainer between €1,000 and €5,000.
Typical data engineering projects
A central data warehouse for company-wide reporting. Real-time dashboards for production or warehouse metrics. Consolidating customer data from multiple systems into a single source for analysis. Preparing the data foundation for a future AI or machine learning project.

Frequently asked questions
Data agencies: questions and answers
What does building a data warehouse cost?
A single pipeline costs €15,000 to €40,000, and a complete data warehouse with BI dashboards €40,000 to €120,000. Agencies charge €130 to €190 per hour. Ongoing operations come on top as a monthly retainer, usually between €1,000 and €5,000.
Do I really need a data warehouse, or is Excel enough?
As long as one person can keep an eye on all the relevant data and you rarely need reports, Excel is often enough. Once you need to combine multiple systems, automate recurring reports, or have several people working from the same numbers, a data warehouse starts to make economic sense.
What's the difference between data engineering and business intelligence?
Data engineering builds the infrastructure that reliably collects and processes data. Business intelligence uses that data for dashboards, reports, and decision support. Many agencies offer both, but the underlying skill sets differ quite a bit, so check where their real focus lies.
How long does building a data infrastructure take?
A single pipeline is ready in four to eight weeks. A complete data warehouse with multiple sources and dashboards takes three to six months. The biggest time factor is usually cleaning and standardizing existing data, not building the pipeline itself.
