# Data you can trust.

> Your data calculations run as code, with automatic checks and documentation, so reports show the same numbers in every tool.

## Calculations that survive change.

Most teams spend more time defending their numbers than using them. Every dashboard defines the same measure slightly differently. Every change in a system breaks a report. The cause is common: calculation logic scattered across dashboards, spreadsheets and one-off queries.

We build the layer that keeps BI unified. Data models under version control, with documented lineage. Automatic checks at every stage and continuous review of changes, so errors are caught before they reach a dashboard. And shared definitions, so numbers mean the same everywhere.

Analysts then trust the data, decision makers get consistent answers, and the knowledge of how each measure is calculated lives in code, not in the heads of two people who might leave.

## What changes for you.

- **Code with history** — All calculation logic in a repository with reviews and instant rollback on any change. No SQL hidden in dashboard settings.
- **Automatic checks** — Checks on structure, freshness and integrity, plus logic checks (for example, revenue within sensible limits). They run on every execution and errors are caught before they reach reports.
- **Shared definitions** — Definitions of measures (for example, "revenue") are set in one place, so they mean the same in every dashboard and analysis.
- **Automatic documentation** — Documentation is generated from the code itself: data lineage, column descriptions and dependencies, visible to anyone who needs them.
- **Calculations in the warehouse** — Raw data is loaded first and calculations run inside the warehouse. It's the modern approach, and it scales better for most workloads.
- **Cost control** — We optimise query speed and cost, so your data warehouse bill doesn't grow faster than the business.
## How we work.

1. **Audit** — We review the calculations, the definitions of measures and the pain points: where logic is scattered, where checks are missing, where knowledge is kept.
2. **Design** — We define the calculation architecture, shared definitions, check coverage and the way of working that will maintain them. We document it before implementation starts.
3. **Delivery** — We migrate or build the models, switch on the checks and set up continuous integration of changes and automatic documentation.
4. **Handover** — We hand over to your team with training in the way of working, or keep running it. The goal is a practice your team maintains and extends, not a black box.
## FAQ

### What do I gain from calculations under version control?
Reproducibility, traceability and safe changes. When definitions live in code with reviews, the knowledge of how revenue is calculated doesn't depend on specific analysts. Changes are reviewed and rollback is instant.

### How do automatic data checks work?
They verify structure (columns exist), consistency (keys match), freshness (data is recent) and logic (revenue within expected limits). They run on every execution and stop the flow if something is wrong, so errors are caught in minutes.

### Do you migrate the logic we already have?
Yes. We document the existing logic (SQL, stored procedures, calculations inside dashboards), check that results match your current reports and migrate it step by step, with a check at each stage.

### Who uses this layer once it's built?
Analysts running queries, BI tools, data scientists training models, ad platforms receiving sales signals and systems like the CRM. It becomes the shared source of truth for everyone.

### Can you train our team?
Yes, training is part of most engagements. We work next to your analysts, document decisions and hand over ownership gradually, so you don't depend on us indefinitely.
