Power BI vs Custom Executive Dashboard for SMBs in 2026

The verdict in three sentences

For an 80-employee SMB with fewer than 20 users, Power BI remains the cheapest choice: USD 14 per user per month and EUR 5,000 to 15,000 excl. VAT of setup are enough to connect the ERP, CRM and bank. A custom dashboard at EUR 15,000 to 40,000 makes sense beyond 50 users, when indicators require specific business logic or when the CEO wants 5 clear numbers on mobile rather than an analyst's tool. Either way, the goal is the same: move from numbers at day 15 to indicators refreshed every day.

Power BI or custom: criterion by criterion

The row that often tips the decision is ease of use. Power BI is a powerful analysis tool, but many executives stop opening reports after 3 months. A custom dashboard shows every morning yesterday's revenue, margin, cash and order book, with an alert when an indicator leaves its range.

3-year cost by number of users

The calculation assumes a Power BI setup at EUR 10,000, a data warehouse at EUR 100 a month, EUR 3,000 of changes per year, and a custom dashboard at EUR 28,000 with 15% annual maintenance and EUR 200 of monthly hosting.

With 15 users, Power BI costs about 35% less. With 60 users (branch managers, sales reps, franchisees), the advantage flips, and the gap widens further if you open the dashboard to customers or partners.

Why numbers arrive at day 15, and what a tool will not fix

A dashboard does not shorten the accounting close. It works around the problem by reading operational sources directly: invoices issued in the ERP, opportunities in the CRM, bank balances via API. Revenue, gross margin and cash become available every day, while the final accounting result keeps its own calendar. Scoping must therefore start with a list of 8 to 12 indicators, their exact definition and source, before any tool choice. This step takes 3 to 5 days and prevents half of failed projects.

Mini case study

Philippe, CEO of an 80-employee building materials distributor in Rennes, turns over EUR 1.5M a month and discovers margin slippage 15 days after month-end. A one-point margin drop costs EUR 15,000 a month: spotting it two weeks earlier saves about EUR 7,500 per incident, or EUR 22,500 a year for 3 incidents. His financial controller also recovers 3 days of Excel compilation a month, about EUR 14,400 a year. With Power BI for 15 users at EUR 31,120 over 3 years, the project pays for itself in under 10 months.

FAQ

How much does Power BI cost an SMB in 2026?

Power BI Pro costs USD 14 per user per month, about EUR 13, so EUR 2,340 a year for 15 users. Add EUR 5,000 to 15,000 excl. VAT of setup depending on the number of sources.

When is a custom dashboard cheaper than Power BI?

As a 2026 order of magnitude, beyond 50 users, or when you open indicators to customers or franchisees. Over 3 years, custom then costs 10% to 20% less.

Can we connect our bank to the dashboard?

Yes, through a PSD2-compliant bank aggregator costing EUR 50 to 200 a month. Balances and transactions update daily with no manual export.

Is our data clean enough for a dashboard?

Rarely on the first try: allow 20% to 30% of the budget to clean customer codes, product families and cost centres. This step determines whether the CEO trusts the numbers.

Can we start with Power BI and move to custom later?

Yes, the data warehouse and indicator definitions are reusable. Migration then costs 30% to 40% less than a custom project started from scratch.
