09 — Data & Analytics

Reporting you can trust, from data you already have.

Most reporting problems are data problems: the same number calculated three ways, reports assembled by hand, dashboards nobody trusts. We build the pipelines, models and dashboards that turn operational data into consistent reporting — and fix the source systems when that's where the problem really is.

    Pipelines process changes rather than full reloads.

  • Access control

    Sensitive figures restricted by role.

  • Lineage

    Every figure traceable to its source.

Process

From first workshop to production.

  1. 01 · Discover

    Workshops with the people who run the process today. We map how work actually moves, where it stalls and what the system must never get wrong.

  2. 02 · Define

    A written scope: users and roles, core workflows, integrations, non-functional requirements and a release plan you can hold us to.

  3. 03 · Architect

    Data model, service boundaries, hosting, security model and the trade-offs behind each choice — reviewed with your team before code starts.

  4. 04 · Build

    Short sprints with a working demo every week. Code review on every change, automated tests on the paths that carry money or data.

  5. 05 · Validate

    Functional QA, role-by-role acceptance, performance checks and a security pass before anything reaches production users.

  6. 06 · Scale

    Staged rollout, monitoring and a support window. Then the backlog of improvements that only real usage reveals.

FAQs

Common questions.

Do we need a data warehouse?

Not always. Many businesses start with a read replica and well-designed reports. A warehouse makes sense when data comes from several systems or volumes grow.

Can you work with data in spreadsheets?

Yes. We often begin by importing spreadsheet data and then move collection into proper systems.

Which dashboard tools do you use?

We build dashboards into your applications with React, or connect established BI tools, depending on who uses them.

How do you keep numbers consistent?

By defining each metric once in the data model and building every report on that definition.

What are data analytics services?

They cover collecting data from your systems, cleaning and modelling it, and presenting it as dashboards and reports people can act on.

Power BI, Metabase or custom dashboards?

BI tools suit internal analysts exploring data. Custom dashboards suit fixed operational views inside your own applications or for customers. We recommend based on who will use them.

Can you combine data from Excel, Tally and our CRM?

Yes. Pipelines can pull from spreadsheets, accounting exports and application databases into one reporting model.

How fresh will the data be?

From near real time to daily refreshes, depending on the source systems and what decisions the data supports.
