Custom predictive analytics dashboard.

A dashboard that doesn't just show what has happened, but predicts what is going to happen. Demand, churn, stock, capacity, anomalies in the financial close: powered by an ML pipeline under the bonnet, a custom visualisation layer on top, and a natural-language layer for people who don't write SQL.

Predicting is more than a report with a trend line running through it.

A classic BI dashboard looks backwards. A predictive analytics dashboard looks forwards: it delivers a forecast for next week, month or quarter, with a confidence margin and an explanation of why the model gives that outcome. The difference isn't a trend line in Excel, but an ML pipeline that continuously retrains on new data and adapts to reality.

We build that pipeline plus the dashboard on top as one cohesive platform. Under the bonnet sits a data warehouse, feature store, set of ML models and orchestration layer; on top, a custom visualisation layer with the charts, filters and alerts your team uses every day. We have been working on AI development projects since 2015, with data pipelines in production at retailers, financial institutions, logistics providers and SaaS companies.

The question we start with is almost always the same: which decision is made on the basis of this forecast, and by whom? A demand forecast that drives purchase orders requires different accuracy and explainability than a churn score that allocates marketing budgets. Forecasts that nobody uses to take action are expensive decoration. And always an audit trail of model versions, features used and predictions made: once a model supports decisions that affect people (HR, customer assessment, credit), the EU AI Act comes into play.

For which forecasts it makes sense.

Demand forecasting, inventory optimisation and churn prediction are the most common use cases. Demand forecasting combines sales data with seasonality, weather, promotions and price changes to produce a forecast per SKU per region. Models that work well here include Prophet for seasonally dominated series, and XGBoost when there are many exogenous features. On top of a demand forecast we often build an inventory optimiser that takes into account lead times, minimum order quantities, storage costs and stock-out costs. For SaaS and subscription businesses we deliver churn scores per active customer, plus the top three reasons the model flags (gradient boosting with SHAP), linked to your CRM so the score lands automatically in HubSpot or Salesforce.

Anomaly detection in operations and financial close flags transactions, stock movements, energy consumption or ledger entries that deviate from the normal pattern. For finance, this saves time during the monthly close: instead of checking thousands of entries, the controller receives a short list of suspicious items. Models include Isolation Forest, autoencoders for multivariate patterns, and statistical detectors for time series with a stable baseline.

Capacity, headcount and financial close forecasting. For service providers managing by billable utilisation, a capacity forecast based on pipeline and historical conversion gives early signals for recruitment. For CFOs, an early-month close forecast provides a sense of direction rather than waiting until after the close. The output often feeds into our custom KPI dashboard, as predictive figures belong in broader management reporting.

Three flavours of predictive analytics.

Most predictive projects fall into one of these three profiles. Which one fits depends on the business decision, your organisation's data maturity and the compliance context. In the first conversation, we advise which profile is right, and we are honest when a standard BI tool is simply the better choice because the predictive element adds no value (yet).

Single-model dashboard on your existing data

One clear use case, such as SKU-level demand forecasting or a churn score per customer, presented in a dashboard that runs on your current data stack. We train the model in Python (scikit-learn, XGBoost or Prophet), deploy it in production behind a REST API, and build a React dashboard on top using Plotly or D3. Your team sees the prediction, the top features the model uses, and a comparison between prediction and actual outcome. This is often a sensible first step for organisations that want to complement their existing BI tool with a predictive layer without rebuilding the entire stack.

Multi-model platform with feature store

Multiple models running side by side on a shared data warehouse (Snowflake, BigQuery, Azure Synapse or Redshift), with a feature store that shares features across models. For example, a retailer with a demand model per category, a churn model for loyalty programmes and an anomaly detector on the transaction stream. Orchestration via Airflow or Prefect, MLOps for drift detection, and a dashboard layer where all predictions come together. Each use case has its own view, but there is one central layer for governance and monitoring.

Real-time predictive with a natural language layer

For organisations that need forecasts on live data, such as logistics, financial markets, energy trading and fraud detection, we build a streaming pipeline on Kafka or Materialize, with models that update incrementally rather than in a nightly batch. On top of that platform sits a natural-language layer powered by an LLM (Claude or GPT-4): your manager asks a question in plain Dutch, and the system generates the SQL and the visualisation. Explainability via SHAP or LIME means every prediction comes with an explanation page that can be presented to a controller or compliance officer. This usually calls for a more thorough AI development approach and often a consultancy phase upfront to prioritise the use-case portfolio.

What you get at the end.

A working predictive platform, not a pilot prototype that gathers dust after three months. Plus everything around it needed to manage, retrain and extend it yourselves, without vendor lock-in to a commercial ML platform.

  • The dashboard application itselfProduction and staging, running in your cloud (Snowflake on AWS, GCP or Azure, BigQuery on GCP, Synapse on Azure) or managed by us. Frontend in React with a custom visualisation layer: Plotly Dash, Streamlit or a bespoke React-D3 implementation, depending on what suits your audience best.
  • Full codebase and ML pipelineSource code for the dashboard app, Python models (scikit-learn, XGBoost, Prophet, PyTorch), feature-engineering scripts and orchestration configuration. Includes Jupyter notebooks from exploration and training runs, reproducible by your own data team.
  • Feature store and semantic layerA central place where features, the derived variables used across several models, are defined and reusable. Business definitions are also captured explicitly, so that models and dashboards work from a single source of truth.
  • MLOps pipelineAutomated retraining on a schedule matched to your data velocity, drift detection when model performance degrades, and MLflow as the experiment tracker. No loose notebooks on someone's laptop, but a professional ML workflow.
  • Explainability layerSHAP or LIME explanations for each prediction, so end users and supervisors can see which features led a model to a given outcome. Not optional for high-risk AI Act applications; for others it boosts adoption.
  • Integration connectorsConnectors to data warehouses (Snowflake, BigQuery, Synapse, Redshift, Databricks), operational databases (Postgres, MySQL, SQL Server), CRM (HubSpot, Salesforce) and ERP. Plus webhooks and a custom REST/GraphQL API so forecasts also flow into your operational systems.
  • Compliance packageGDPR (PII redaction, encryption, EU data residency, DPIA) and the AI Act (classification, an audit trail of model versions and predictions, and human oversight where the law requires it). For sector-specific regimes (NEN 7510 in healthcare, DORA in finance), the additional governance documentation.
  • Admin manual and end-user trainingFor your administrators: how to retrain, how to add features, how to interpret drift alerts, how to roll back. Plus two sessions for key users and short video tutorials for day-to-day users, including a guide on how to read a prediction.
  • Maintenance contract (optional)Monitoring, model drift tracking, security patches and ongoing development. Usually recommended for predictive platforms, as models need continuous attention: data changes and behaviour shifts, and without periodic retraining every model eventually degrades.

When a predictive analytics dashboard genuinely adds value.

Four patterns where we help organisations build their own predictive platform. Recognise one of them? Then let's talk further. If you don't, a classic BI dashboard is probably the better choice; predicting without a decision attached to it is expensive decoration.

Procurement & supply chain

Demand peaks keep catching you out

You order based on gut feeling or trend, and reality regularly proves you wrong. A demand forecast per SKU based on seasonality, weather and promotions significantly improves your chances of getting purchasing right. Often paired with building a BI tool when the wider reporting layer is being renewed at the same time.

Customer success & retention

You spot churn too late

You only find out a customer has gone when the cancellation email arrives. A churn score with top reasons per customer gives customer success a targeted priority list and gives marketing an audience for retention campaigns. Works best with a few hundred to several thousand active customers.

Finance & control

Month-end close eats hours

Your controller manually works through thousands of entries every month. An anomaly detector on your general ledger produces a short list of suspicious transactions, with the reason for each item. It can be combined with a close forecast that gives direction early in the month, and extended via our KPI dashboard page towards broader management reporting.

Operations & capacity

Capacity keeps falling behind

You're late to hire or bring in contractors because you only react once the bottleneck is visible. A headcount or capacity forecast based on pipeline data and historical conversion shows you what's coming earlier, early enough to act effectively. Applicable in service businesses, contact centres, clinics and agencies.

How a predictive project works.

1

Introduction & use-case prioritisation

A conversation to understand which decision a prediction should support, who will act on it, and what data is available. We check straight away whether the business case justifies prediction or whether a backward-looking dashboard is enough; often a standard BI tool is the right step. An exploratory consultancy phase can also be run through our AI consultancy approach.

2

Data discovery & feature engineering workshop

A workshop with your data team plus interviews with the end users. We map the sources, identify which features are likely to be predictive (and which contain data leakage because they only become available after the prediction point), and design the pipeline architecture. At the end: a concrete scope, tech stack choice and a baseline measurement of your current «forecasts» (often Excel trend lines or gut feel).

3

Model training & first dashboard build

In the first sprints we train one model on your existing data and build a first dashboard view on top of it. Not a Kaggle experiment, but the simplest configuration that actually beats the baseline; surprisingly far can often be achieved with XGBoost or Prophet on well-built features. Your team tests alongside us.

4

Pipeline, MLOps & feature store

The model and dashboard are embedded in a production pipeline: orchestration (Airflow or Prefect), experiment tracking (MLflow), drift detection and a feature store that makes derived variables reusable across models. From here, a second and third model can be added on the same infrastructure.

5

Compliance audit & explainability layer

Before going live: GDPR DPIA, AI Act classification, penetration test, audit trail review and the explainability layer (SHAP per prediction). For sector-specific regimes (NEN 7510 in healthcare, DORA in finance), the additional governance documentation. Models that directly affect people get extra human oversight built in.

6

Rollout, further development & retraining

Phased rollout, training sessions for key users and ongoing management of security and model performance. Retraining on a schedule that suits your data velocity. Expansion to further use cases on the same infrastructure in subsequent sprints.

The technical choices along the way.

The data warehouse layer is the central place where all sources come together: Snowflake for multi-cloud setups or heavy compute spikes; BigQuery for Google Cloud or pay-per-query; Azure Synapse for Microsoft environments; Databricks when ML and data engineering need to live on one platform. For real-time cases, a ClickHouse or Materialize often sits alongside. We stay vendor-neutral across all four.

We build the ML pipeline in Python: scikit-learn for straightforward classification and regression; XGBoost or LightGBM when there are many structured features and you need SHAP explainability; Prophet or statsmodels for classical time series; PyTorch where a neural network genuinely adds value. For most use cases, a well-tuned XGBoost outperforms a PhD-level neural network and is far easier to maintain. Orchestration runs on Airflow or Prefect, with MLflow as the experiment tracker so every run is reproducible.

The visualisation layer depends on the audience: Plotly Dash or Streamlit for data analysts and domain experts; a bespoke React front end with D3 or ECharts for end users who expect a polished interface. We build the AI layer with Claude or GPT-4, using a text-to-SQL controller that validates queries against an allowlist, and a semantic layer (dbt or similar) that makes business definitions explicit. The compliance layer is embedded in every component: PII redaction, EU data residency, an audit trail of model versions and predictions made, model cards, and human oversight where the AI Act requires it.

Bespoke versus Power BI or Tableau.

"Why not just use Power BI or Tableau?" comes up in almost every first conversation. For classic BI (looking back at your own data, ad hoc queries, standard reporting for your own team), both tools are excellent, and a custom build would waste both money and time. We don't build a replacement for Power BI; if you only need reporting, that is usually the right route.

The picture changes once machine learning enters the picture. Power BI has AI Insights and some AutoML, Tableau has Einstein Discovery. Both work well for demo cases, but they run into trouble as soon as you want to define your own features, train non-trivial models, or version and roll back models. For serious predictive work, a custom Python pipeline alongside (or instead of) standard BI is needed. Beyond that: vendor independence (Power BI ties you to Microsoft, Tableau to Salesforce, Looker to Google), code ownership (all code is yours, with no lock-in), and model explainability (SHAP and LIME are mature tooling within Python pipelines and are not standard in Power BI or Tableau, and "Power BI has it covered" is not an acceptable answer to a regulator under the AI Act). If you recognise yourself in any of these four, a custom platform is the logical step; if you recognise none of them, our honest advice is to use Power BI or Tableau and come back to us when you get stuck.

Frequently asked questions.

What clients typically want to know before we start on a predictive analytics dashboard.

What is the difference between a BI dashboard and a predictive analytics dashboard?
A classic BI dashboard shows what has happened: sales history, customer volumes, stock movements. A predictive analytics dashboard looks ahead and forecasts what is coming: next month's demand, churn probability per customer, anomalies in the financial close. Under the bonnet sits an ML pipeline that continuously retrains on new data, plus a feature store that keeps input variables consistent across models. A BI tool is set up on your data and it works straight away; a predictive platform calls for a design phase in which you choose which decisions should be supported and which data is relevant to them.
Will you replace our current Power BI or Tableau environment?
Not for the standard BI use case — Power BI and Tableau are excellent for analysts and day-to-day reporting. What we do instead is add a predictive layer alongside your existing BI environment. Often Power BI keeps running for standard reporting and our predictive dashboard is added for forecasting and anomaly use cases. For some clients the predictive platform eventually replaces the classic BI layer as well, but that is not a requirement.
How accurate is a demand forecast or churn prediction, really?
That depends heavily on data quality and the use case. For seasonal retail categories with several years of history, forecast errors around ten per cent (WMAPE at SKU category level) are a realistic target; for highly volatile or new products, higher. For churn prediction we look at AUC and precision/recall — good models typically reach an AUC of 0.80–0.90, but the real business value lies in how much of your retention budget reaches the right customers. We always measure against a baseline and only go live if the model beats that baseline by a measurable margin.
How far along is a natural language layer with LLMs, really?
Further than most people think, provided you build in the right guardrails. An LLM such as Claude or GPT-4 can reliably turn a question like "what is the expected cash position at the end of Q3 if the top ten deals go through?" into SQL plus a visualisation, as long as you supply a good semantic layer that explicitly defines column names, business definitions and joins. We build text-to-SQL with a validator that checks each query against a whitelist of tables, columns and aggregations, plus row-level security that prevents the LLM from retrieving data outside its scope. For EU AI Act compliance we log which questions were asked and which SQL resulted — that audit trail is mandatory for high-risk AI systems.
Which data do you need to get started?
As a rule of thumb: at least two years of history for the variable you want to predict, plus as many contextual features as possible. For demand forecasting: sales per day or week per SKU per location, plus price, promotions, stock, weather and seasons. For churn prediction: contract data, usage data, support tickets and NPS. In our experience data quality matters more than volume. During discovery we carry out a data quality audit and honestly tell you whether both volume and quality are sufficient — sometimes the conclusion is that you need to clean up your data first.
How do you handle the EU AI Act and GDPR?
First the classification: which risk level does your use case fall under the EU AI Act? Minimal risk (demand forecasting, anomaly detection on operational data) carries limited obligations. High risk (recruitment, credit granting, health advice) requires strict documentation, an audit trail, human oversight and sometimes a conformity assessment. For GDPR: a DPIA for every model that touches personal data, PII redaction in the feature layer where possible, and EU residency for both data and models. For clients in regulated sectors we work with European cloud tenants as standard.
Can this be integrated with our existing data stack?
Almost always, and that's usually the point. We build connectors to data warehouses (Snowflake, BigQuery, Synapse, Redshift, ClickHouse, Databricks), operational databases (Postgres, MySQL, SQL Server), CRM (HubSpot, Salesforce), ERP systems and specific APIs. For ETL we use dbt, Airflow or Fivetran, depending on your existing set-up. If you don't have a warehouse yet, we can build one too, usually as a linked data warehouse project, so the predictive platform sits on a reliable data foundation.
What is the difference from a KPI dashboard?
A custom KPI dashboard shows how your business is currently performing against agreed targets: KPIs, target versus actual, and trends by department. A predictive dashboard forecasts where those KPIs are heading and shows the drivers behind the forecast. In practice the two overlap. Many clients start with a KPI dashboard and, after a few months, want a predictive layer on top, such as an end-of-year forecast alongside the actuals, or a drill-down that predicts which department is likely to miss its target. We also often build both in one project when the audience and data source largely coincide.
How often do models need to be retrained?
It depends on data speed and use case. For demand forecasting in retail we often retrain weekly; for churn prediction in subscription businesses monthly is usually enough; for anomaly detection on fast streams, daily or continuous retraining may be needed. There's no manual work: the orchestration layer runs on a schedule and MLflow logs every run so it can be reproduced. Drift detection raises an alert when a model starts to deteriorate. A set-and-forget approach isn't an option: data changes and behaviour shifts, and without periodic retraining every model eventually degrades.
What if the model gets things wrong?
Expect it to happen and build for it: a confidence margin on each prediction, SHAP explanations for each prediction, human-in-the-loop review for high-impact actions, an audit trail of who decided what based on which prediction, and a rollback procedure to an earlier model version. Models without an error-handling procedure are not production-ready. This matters more in ML than in traditional software because the nature of errors is less predictable.
Do you work alongside our data team?
Almost always. For some clients we deliver the entire platform, including operations; for others we work alongside an internal data team that takes over the models. Knowledge transfer in the final sprints, an incident runbook, and clear responsibilities for monitoring, retraining and further development. Code ownership always stays with you, with no vendor lock-in.
What determines the cost of a predictive analytics project?
Three factors weigh most heavily. One: the number of models and their complexity. A single demand forecast is fundamentally a different project from a multi-model platform with churn, forecasting and anomaly detection. Two: data maturity. Does the warehouse already exist, or does a data engineering project need to run alongside? Three: the compliance and explainability layer. High-risk AI Act use cases require additional documentation and human oversight. We work with a fixed sprint budget so you can adjust scope from sprint to sprint.
How long before we can go live?
A first working model on your existing data stack is ready after a few sprints. A full multi-model platform with a feature store, MLOps and several dashboard views is a project of several sprints on top of that. We work in two-week sprints with a working build at the end of each, so you see progress early and can steer along the way. A phased approach also works: first one model in production, then expanding to further use cases on the same infrastructure.
