Your Coventry plant's Power BI is pretty and your delivery number still can't be trusted
A BI dashboard in a Coventry plant is only as honest as the data beneath it, and Tableau, Power BI, or Looker happily render a delivery-performance number that three disconnected systems can't actually agree on. Custom BI, built on a proper data layer, costs £30,000 to £90,000 over 2 to 5 months and pays back when your OEM-facing KPIs finally reconcile to a single source the auditor trusts.
Power BI and Tableau are visualisation tools, not truth tools. Point them at a Coventry manufacturer's reality, an ERP (Enterprise Resource Planning), a quality spreadsheet, and a despatch log that each hold their own version of delivery and PPM, and you get a beautiful dashboard built on numbers that disagree. The board looks at a confident KPI that nobody in operations actually believes, because they know it depends on which export was used.
The exposure is sharpest on OEM-facing metrics. Your delivery performance and parts-per-million defect rate are scored by your customers, and if your internal dashboard says one thing while the OEM's portal says another, the conversation isn't about the chart, it's about your credibility. A dashboard that visualises unreconciled data is worse than no dashboard, because it manufactures false confidence.
What business intelligence dashboards costs in Coventry
| Project scope | Typical cost | Timeline |
|---|---|---|
| Reconciled data layer with core KPI dashboards | £30k to £50k | 2 to 3 months |
| Add OEM metrics and shop-floor OEE | £50k to £70k | 3 to 4 months |
| Full BI platform with drill-down and alerts | £70k to £90k | 4 to 5 months |
The fix: business intelligence dashboards built for Coventry, not rented
Custom BI starts with a data layer that reconciles your sources into one trusted set of figures, then visualises that. Your delivery performance, PPM, OEE, and margin come from one place that agrees with the OEM, so the dashboard becomes a tool for decisions and audits rather than a source of arguments. The chart is the easy part; the reconciled data underneath is the value.
- Your KPIs disagree across systems and nobody trusts them
- OEM-facing metrics must match the customer's portal
- Decisions stall because the numbers are arguable
- You need a trusted data layer other tools can share
- Your data already lives in one trustworthy system
- A standard Power BI connector genuinely suffices
- Your metrics aren't scored by external customers
- You only need basic charts, not reconciled truth

The engagements Coventry teams bring us most often: data visualization, Tableau alternative, Power BI, Looker and real-time analytics.
How long it takes, phase by phase
Exactly what you get
BI built from the data up: a layer that reconciles your ERP, quality, and despatch sources into one trusted set of figures, then dashboards for delivery performance, PPM, OEE, and margin that agree with what your OEM customers see. Every KPI drills down to the underlying transactions for audit, and scheduled reports feed management and customer reviews. It draws from your ERP, your inventory management system, and your accounting software, becoming the single trusted source those systems and your team all read.
How to choose a developer in Coventry
Ask candidates how they'd make your delivery number match the OEM's portal, and watch whether they talk about data reconciliation or about chart types, because the value is entirely in the former. A developer who knows Coventry's automotive supply base will understand that your delivery and PPM metrics are scored by JLR and the Tier-1s, and will build the reconciled data layer first so the dashboard protects your credibility instead of undermining it.
- KPIs built on one reconciled data layer, not three disagreeing systems
- OEM-facing metrics that match the customer's portal, protecting credibility
- Operations actually trusting the numbers, so dashboards drive decisions
- Delivery, PPM, OEE, and margin from a single source for audit
- A foundation other systems and reports can draw the same truth from
- The real work is in data reconciliation, which is unglamorous and takes time
- Garbage-in still applies; source-data discipline is required
- More than a Power BI licence and a quick dashboard
- Overkill if your data already lives in one trustworthy system
- !They sell the visuals; ask how they reconcile data before charting it
- !No data-layer plan; ask how they make three sources agree
- !No OEM-metric alignment; ask how the dashboard matches the customer portal
- !No drill-down; ask how a KPI traces back to transactions for audit
- !They ignore source-data quality; ask how they handle garbage-in

Frequently asked questions
Isn't Power BI enough for dashboards?
Power BI is a fine visualisation tool, but it renders whatever data you point it at, including three systems that disagree about your delivery number. The value isn't the chart, it's the reconciled data layer underneath, which is exactly what a custom build provides and a quick Power BI dashboard doesn't.
Why do our KPIs disagree?
Because your ERP, quality spreadsheet, and despatch log each hold their own version of delivery and PPM, so the number depends on which export was used. A reconciled data layer resolves them into one figure, which is what lets operations and the board actually trust the dashboard.
Why does matching the OEM portal matter?
Because your delivery performance and PPM are scored by your customers, and if your dashboard disagrees with their portal, the conversation becomes about your credibility rather than the data. Aligning your metrics to the OEM's view protects the relationship.
What does custom BI cost?
A reconciled data layer with core KPI dashboards runs £30,000 to £50,000. Adding OEM metrics and shop-floor OEE takes it to £70,000, and a full BI platform with drill-down and alerts reaches £90,000, over 2 to 5 months.
Can we still use Power BI on top?
Yes. Many builds put the reconciled data layer underneath and let Power BI or Tableau visualise it, so you keep familiar tools while fixing the trust problem at the source. The point is reconciliation first, visualisation second.

Who can build custom business intelligence dashboards for a business in Coventry?
Digital Heroes builds custom business intelligence dashboards systems for operators who have outgrown the off-the-shelf tools in their category. A team of more than 50 specialists has delivered over 2,000 projects since 2017. Teams work from New York, London, Sydney, Delhi and Lucknow and deliver remotely, so an operator in Coventry gets an assigned senior team rather than a local account manager.
Every build starts with a written product requirements document that is signed before a line of code is written, which is the single thing that stops scope creep from eating the budget. Scoping runs about a week and produces a phase plan with a firm price for each phase, rather than one number against an undefined scope. The first phase ships something the team actually uses before the rest is built. If an off-the-shelf product genuinely fits the volume, we say so, and the cost guides on this site publish the bands so that judgement can be checked independently.
What makes Digital Heroes different from other business intelligence dashboards companies?
Four things that competitors in this bracket cannot simply copy. Digital Heroes runs a YouTube channel with more than 2.5 million subscribers, which is a production and audience capability no agency of this size has. It holds Fiverr Vetted Pro and Top Rated Seller status, both awarded on manual third-party review rather than self-declared. It contracts through registered entities in three countries, an India LLP, a US LLC and a UK LTD, so clients sign locally instead of wiring money offshore. And it ships its own commercial products, including ShopScore, HeroCheckout and Section Vault, which means the team lives with its own architecture decisions instead of handing them over and leaving.
Two more that show up in the work. Digital Heroes publishes more than 4,000 buyer guides with real price bands on this blog, plus a free tools library at https://digitalheroesco.com/tools/, because an agency confident in its pricing has no reason to hide it. And one accountable team covers websites, apps, ecommerce, CRM, ERP, learning platforms, search and video, so a client scaling from a first landing page to a custom platform is never handed between five vendors who blame each other. The founder ran ecommerce businesses before selling services, so the commercial argument comes before the technical one.
