Last position:
Business Intelligence Consultant (freelance) at NBIC – Nisanthan BI Consulting
Advising companies on building, migrating and optimising BI and reporting landscapes (Power BI, SQL, Python, ETL)
5 client engagements in real estate and finance since 05/2025: taking over and stabilising existing reporting, automating recurring standard and management reports, building cash-flow models
Proposal and feasibility assessments for BI and reporting projects
Using AI-assisted development (Claude Code) to accelerate automation, tooling and web/app development
Custom ERP system
Problem: A client's core processes ran on scattered, siloed Excel files with no central data storage – error-prone, hard to scale and impossible to analyse end-to-end.
Approach: Captured the business processes and requirements, modelled the data and developed iteratively together with the business team.
Implementation: Built a tailored, web-based ERP system with a central database, role-based modules and automated reporting – delivered using AI-assisted development in Claude Code.
Timesheet app
Starting point: Time tracking based on an overgrown, macro-heavy Excel template – maintenance-intensive, single-user and error-prone.
Implementation: Migrated all functionality and VBA macros into a standalone web app with central data storage, multi-user support and automated reporting.
Cash-flow modelling
Starting point: The existing cash-flow model covered standing investments only; project developments were missing from steering.
Implementation: Built and extended the CF model to include project-development cash flows.
Optimisation: Reviewed and optimised existing CF models and expanded the KPI outputs for reporting and steering.

About the role
What they do
A BI Consultant turns business data into reports, dashboards, and analysis that teams can trust. They gather requirements, map KPIs, design data models, and shape the flow from source systems to decision-ready output. In many projects, they also act as the bridge between business users, analysts, and IT.
Typical deliverables
- Dashboard and report concepts for sales, finance, operations, or management
- Data models and KPI definitions that keep reporting consistent
- SQL queries, ETL logic, or semantic layer changes
- Power BI, Tableau, or Qlik dashboards with clear drill-downs
- Documentation for data sources, metrics, and reporting rules
Core skills
A strong BI Consultant combines business understanding with technical depth. SQL is usually essential, along with data modelling, dimensional design, and a solid grasp of data quality issues. Many projects also need hands-on work in Power BI, Tableau, Qlik, Azure, Snowflake, SAP BW, or similar stacks.
- requirements analysis and workshop facilitation
- dashboard design and KPI structuring
- ETL and data pipeline understanding
- performance tuning for reports and queries
- clear communication with non-technical stakeholders
When companies hire one
Companies bring in a freelance BI Consultant when reporting needs to move faster than an internal team can handle. That often happens during ERP changes, data warehouse rebuilds, dashboard overhauls, or when management wants a single source of truth across departments. A freelancer is also useful when a company needs short-term expertise in a tool such as Power BI or Tableau without adding a permanent headcount.
What good looks like
The best BI consultants do more than build nice dashboards. They question the metric logic, clean up unclear source data, and make sure the output supports real decisions. They document their work, keep business and IT aligned, and leave behind a reporting setup that others can maintain.
Working setup
Many BI projects can be delivered remotely, especially if access to data, stakeholders, and test environments is set up well. On-site sessions help when the scope is unclear, the data landscape is messy, or the team needs help agreeing on KPIs. In Germany and other DACH settings, English is often enough for technical work, but local language skills can help in workshops and user training.
Frequently asked questions
Not sure where to start with BI Consultant? These answers cover the essentials.
A BI Consultant defines reporting needs, translates them into data models, and helps build dashboards and reports that support business decisions. They often work on KPI definitions, source-system mapping, SQL, and validation with users. In many projects, they also help fix broken reporting logic and improve data quality.
A strong BI Consultant should understand SQL, data modelling, and dashboard design. Practical experience with tools such as Power BI, Tableau, or Qlik is common, along with a good eye for KPI logic and reporting performance. Just as important is the ability to talk to business users without turning the work into a technical black box.
Not always. A BI Consultant often sits between the business and the technical build, while a data analyst focuses more on analysis and a BI developer is usually closer to implementation. In practice, the titles overlap, so the right fit depends on whether you need strategy, reporting design, or hands-on dashboard work.
A freelance BI Consultant makes sense when you need focused expertise for a specific reporting, dashboard, or data modelling challenge. It is also a good option when the project is time-sensitive or the internal team lacks a certain tool or domain skill. Freelancers are useful when you want to move quickly without creating a long hiring process.
Common tools for a BI Consultant include Power BI, Tableau, Qlik, SQL, Excel, and often cloud or warehouse platforms such as Azure, Snowflake, or SAP BW. The exact stack depends on the company’s data landscape. What matters most is that the consultant can work across source data, modelling, and the final reporting layer.
A BI Consultant can work well remotely when access to data, users, and decision makers is organized. On-site time helps during workshops, KPI alignment, and when legacy data issues need fast discussion. Many companies use a mix of both, with remote delivery and selected on-site sessions.
Look for clear questions, strong examples of past reporting work, and the ability to explain data models in plain language. A good BI Consultant will ask about KPI ownership, data sources, and how the reports will be used before jumping into build mode. Quality also shows up in documentation, testing, and the way they handle edge cases and data inconsistencies.
Freelance BI Consultants should expect a mix of stakeholder workshops, data mapping, technical build, and iteration based on feedback. The best assignments are not just dashboard delivery; they also include cleaning up metric definitions and improving reporting processes. Being comfortable with business context is often as important as technical skill.
The average hourly rate for BI Consultant is 109 €, which corresponds to a daily rate of about 870 € based on an 8-hour working day.
