Database & Business Intelligence: Data warehouses, ETL and reporting

We design and implement database solutions and BI systems so you can make decisions based on reliable, consolidated data.

Database & Business Intelligence

Our database and BI services

From data warehouses and ETL to reports and dashboards: we help you bring data together from many sources, keep it reliable and give management the views they need. We use SQL, PostgreSQL, MySQL, Power BI, Metabase and custom backends, and we connect to your ERP, CRM and other systems.

  • Data warehouse design and implementation
  • ETL and data integration
  • Reporting and dashboards (Power BI, Metabase, custom)
  • SQL optimization and data modeling
  • Self-service BI and training

From scattered data to clear insights

Many companies have data in ERP, CRM, spreadsheets and other systems but struggle to get a single, reliable view. We design data warehouses and ETL pipelines that bring sources together, cleanse and validate data and make it available for reporting and analytics. Dashboards in Power BI, Metabase or custom front ends give management and teams the metrics they need without waiting for IT. We optimize SQL and data models for performance and document everything so your team can maintain and extend the solution.

Self-service BI and training help your users work with the data safely and consistently. We integrate with your existing ERP and CRM so new data flows in automatically. Get in touch for a free consultation – we outline options, typical scope and next steps without obligation.

Frequently Asked Questions

Database & Business Intelligence

Data & BI Setup

What is the difference between database solutions and BI?

Database solutions handle storage, queries and integration; BI builds on that with reporting, dashboards and KPIs. We often deliver both so you get a single source of truth and clear insights.

Can you connect our existing data sources?

Yes. We connect ERP, CRM, databases and APIs into a central data layer or warehouse so you get consistent reporting across systems.

How much does a BI or database project cost?

Costs depend on sources and complexity. A first dashboard often from the mid five figures; larger data platforms more. We give an estimate after a short briefing.

How do you ensure data quality?

We define ownership, governance and validation in pipelines so decisions are based on reliable data. We document and train your team.
