The reporting tools that get compared with Power BI fall into four groups, and the right one depends on what the report is for, not on which tool is "best". Excel with Power Query is already installed, costs nothing extra, and is the right answer for a report one or two people refresh and read. Finance add-ons (Xero Analytics on Xero's Ultimate plan, Fathom, Syft, Spotlight, Joiin) produce a management pack or a consolidation from the accounts system with almost no setup and are right when everything you need is in the ledger. Tableau and Looker Studio are general BI tools like Power BI, with different pricing and different strengths. And the dashboards inside your CRM or ERP (HubSpot, Salesforce, Dynamics, Business Central's free Power BI apps) are right for questions about that system, for people who log into it. Power BI is the right pick when the report joins systems, is shared with people who should see different slices, refreshes itself, and lives in a Microsoft 365 business. That's a lot of UK businesses, but it isn't all of them, and I'd rather say so.
The comparison, with prices
| Tool | What it's for | Published price (as of September 2026) | Strengths | Where it stops |
|---|---|---|---|---|
| Excel + Power Query / Power Pivot | One-reader reports, month-end workbooks | Included in Microsoft 365 | Already there; same Power Query as Power BI; finance people know it | No scheduled refresh, no row-level sharing, fragile at scale |
| Power BI Pro | Shared, scheduled, secured reports over one or more systems | £10.80 per user per month, paid yearly, excl VAT (Microsoft UK) | Modelling depth, row-level security, mobile, Microsoft 365 integration, native connectors for Business Central, Dynamics, Salesforce, SQL | Per-viewer licence; Xero, QuickBooks, HubSpot need third-party connectors |
| Power BI Premium Per User | As Pro, plus larger models and more refreshes | £18.50 per user per month (Microsoft UK) | Bigger data, 48 refreshes/day | Same |
| Xero Analytics (Syft-powered) | KPIs, ratios, cash projection inside Xero | Included in Xero Ultimate, £70 per month (xero.com/uk) | No setup; single-entity finance | Xero only, single entity, no external data |
| Fathom / Syft / Spotlight / Joiin | Management packs, consolidation, KPIs from the accounts | Subscription; see each vendor's page (not printed here, they vary by entity count) | Fast pack, consolidation for Xero and QuickBooks, accountant-friendly | Ledger data only; no CRM or operations joins; the view is rented |
| Tableau Cloud Standard | General BI, strong visual exploration | $15 Viewer / $42 Explorer / $75 Creator per user per month, billed annually (Enterprise $35/$70/$115) | Visual analysis, large-data exploration | Dearer per viewer than Power BI; less native in a Microsoft 365 business |
| Looker Studio / Looker Studio Pro | Web and marketing dashboards, Google data | Free; Pro $9 per user per Google Cloud project per month | Free tier, Google Analytics and Ads connectors | Weak modelling; per-project pricing on Pro; not built for finance |
| CRM / ERP built-in dashboards | Questions about that system, for its users | Included in the system's licence | No setup, in the tool people use | Only that system; caps by tier; not for people without a licence |

How to choose
Four questions decide it.
Is everything you need inside one system? If yes, and that system is the accounts, try the finance add-ons or the accounts system's own pack first (Can Xero Produce Management Accounts? Yes, and Here's Where It Stops). If it's a CRM, try its dashboards. If it's an ERP with free Power BI apps (Business Central), install them. Don't buy a general BI tool for a single-system question.
How many people read it, and should they all see the same thing? One or two readers, same view: Excel. Ten readers, each seeing their own region or department: a BI tool with row-level security, which Power BI has and Excel doesn't.
Does it have to refresh without a person? If someone opening a file is acceptable, Excel. If the page has to be current at 6am on a Monday whoever's on holiday, Power BI's scheduled refresh (or another BI tool's).
What's the rest of your stack? A Microsoft 365 business with Business Central, Dynamics 365 Sales, SQL Server or SharePoint has native Power BI connections to all of them and every user already has a Microsoft login. That tilts the decision hard. A Google Workspace business running on Google Analytics and Sheets tilts the other way, at least for marketing reporting.
Where Power BI genuinely wins, and where it doesn't
Wins: the semantic model (one set of definitions every report shares, which is what stops six reports showing six numbers, see Six Reports, Six Different Revenue Numbers); row-level security; the per-viewer price against Tableau; native connectors to the Microsoft stack and to SQL; mobile layouts; and the sheer number of people in the UK who can work in it, which matters when the person who built it leaves.
Doesn't: it's a per-viewer licence, so a hundred occasional readers is a real cost (Fabric capacity changes that maths at scale, but not for an SME); Xero, QuickBooks Online and HubSpot have no native Microsoft connector as of September 2026, so those need a third-party connector or some engineering (How to Connect Your Accounting Software to Power BI); visual exploration of large, messy data is where Tableau's fans are right; and for a single-entity Xero business wanting a pack, Xero Analytics or Fathom will be live this afternoon and Power BI won't.
What about "AI-built dashboards"?
Worth a paragraph because it's the fifth group people ask about now. Tools that generate a dashboard from a prompt are real and improving, and for a one-off view of a clean dataset they're useful. For a report that has to reconcile to the ledger, refresh every morning, and show each manager only their slice, the questions are the same as for any tool: what's the model, who maintains it, does it tie. I've written it up at Should You Replace Power BI with an AI-Built Dashboard?.
Where does that leave a UK SME?
Usually: Excel for the one-reader workbooks, the accounts system's pack or an add-on for the monthly finance pack if it's single-entity, the CRM's own dashboards for the sales team, and Power BI for the reports that cross systems or reach people who don't log into any of them (the board page, the MD's phone, the department heads' own slices). That's four tools, and it's the right number; the mistake is trying to make one of them do all four jobs.
If the Power BI piece is one report from one system, that's a First Report: £1,950 fixed, ten working days, published to your workspace with the headline figure reconciled to the source (see the First Report). If you're not sure which group your need falls into, the Setup Hour is an hour with your data for £195, and "you don't need me, use Xero Analytics" is an answer I give.
Common questions
What are the alternatives to Power BI?
Excel with Power Query for one-reader reports; finance add-ons like Xero Analytics, Fathom, Syft and Spotlight for packs from the accounts; Tableau and Looker Studio as general BI tools; and the dashboards built into your CRM or ERP. Each fits a different job.
Is Tableau or Power BI better?
For a Microsoft 365 business with a per-viewer budget, Power BI: Pro is £10.80 per user per month (Microsoft UK, September 2026) against Tableau's $15 to $75 per user per month, and the native connectors to the Microsoft stack matter. Tableau's strength is visual exploration of large datasets. Both are capable; the stack and the price usually decide.
Is Looker Studio a good free alternative to Power BI?
For marketing and web reporting on Google data, yes, and the free tier is real. For finance reporting, modelling and row-level security, it's the weaker tool, and Looker Studio Pro's per-user-per-project pricing ($9 as of September 2026) adds up in a multi-project setup.
Do I need Power BI if I have Xero Analytics or Fathom?
Not if everything you need is in the ledger, for one entity, read by people who can log into the tool. Those add-ons are quicker and cheaper for that. Power BI earns its place when the report joins the CRM or operations, or is read by people outside the accounts system.
What's the cheapest reporting tool for a small business?
Excel with Power Query, which is already in Microsoft 365, for reports one or two people use. It stops being the cheapest when someone's day a month goes on maintaining it, or when it needs sharing with different slices per person.
What does Power BI cost per user in the UK?
Power BI Pro is £10.80 per user per month and Premium Per User is £18.50, both paid yearly and excluding VAT, on Microsoft's UK page as of September 2026. Fabric capacity is priced separately and in USD; the details are in What Power BI Licensing Actually Costs in the UK (2026).
Which reporting tool is best for Xero?
Inside the ledger: Xero's own Management Report pack, then Xero Analytics on Ultimate, then Fathom or Syft for more. Joining Xero to a CRM or a job system, or reporting to people without a Xero login: Power BI, through a third-party connector or the API, since there's no native Microsoft connector.
