Business dashboard vs spreadsheet vs Power BI: which should you use?

"Should we use a spreadsheet, Power BI or get a dashboard built?" is a fair question with no universal answer. This guide compares the options honestly, including when the cheaper and simpler choice is the right one. For the wider picture, read the complete guide to business dashboards.

The options at a glance

	Spreadsheet	Off-the-shelf reporting tool (for example Power BI or Looker Studio)	Reports built into your software	Custom dashboard
Best for	Ad hoc analysis, small jobs, one person	Reporting across several common data sources	Numbers that all live in one product	Joining several systems, your own rules, role-based views
Who builds it	You	You or an analyst	Already built	A developer, with you
Combining systems	Manually	Through connectors	No	Yes, including systems with no connector
Access control by role	Poor	Good, if configured	Depends on the product	Designed to your needs
Accuracy risk	High as it grows	Lower, if the data feed is solid	Low	Low, with tested data feeds
Ongoing upkeep	Whoever built it	Someone who knows the tool	The software supplier	A supplier or your team
Watch for	Copied versions, broken formulas, depends on one person	Someone must build and maintain every report	Limited to that product	Needs a clear spec and an owner

Spreadsheets: where they work and where they don't

Spreadsheets are flexible, familiar and fine for one-off analysis, quick calculations and small data sets. They struggle when they become the system everyone relies on.

The risk is documented:

What was found	Who found it	Read it with care
Serious errors were found in 91% of 55 operational spreadsheets across five field audits (1995 to 2000), and about 83% of 163 spreadsheets across nine studies (1995 to 2008)	Raymond Panko, summary of spreadsheet audits	Counts errors "serious in the context of the spreadsheet's use". Thresholds varied between studies, and reviewers miss errors, so the true rate is probably higher. The audits are older, so treat this as a warning, not a current measurement

Signs your spreadsheets have had their day:

• More than one version circulates.
• It depends on one person who understands the formulas.
• Updating it takes hours each week.
• People argue about whose figures are right.
• It combines data pasted in from several systems.

Signs your business has outgrown spreadsheets goes through this in more detail.

Off-the-shelf reporting tools

Tools such as Power BI and Looker Studio are good. If your data comes from common sources with ready-made connectors, and you or someone in your team can set them up and look after them, they may be all you need, and you'd be right not to pay for custom work.

Things to check before you commit:

• Does every source you need have a good connector? If one important system doesn't, you're back to manual uploads.
• Who will build and maintain each report? A tool doesn't build itself, and reports break when a connected system changes.
• How are access and sharing handled? Check licensing and how you can restrict who sees what. Pricing and licensing change, so check the supplier's current terms rather than relying on a guide.
• Can people use it? A tool nobody is comfortable with ends up unused.

Reports built into your software

Xero, a CRM, a booking system or your shop platform will include reporting. If all the numbers you care about live in that one product, use it. It costs nothing extra to build and the supplier looks after it. The limit is obvious: it only knows its own data.

Custom dashboards

A custom dashboard makes sense when:

• Your numbers come from several systems, and at least one has no good connector.
• You have business rules the off-the-shelf options can't express, such as how you define a job's status or margin.
• Different people need different views, with access that follows your roles.
• You want the dashboard to sit inside the way your team already works, alongside the actions they take, not as a separate report.
• You want someone responsible for keeping it accurate when connected systems change.

Because it is built for you, it takes a clear specification and a supplier who will look after it afterwards. Our business dashboard service is built around that, and when a business needs custom software covers the wider decision.

Questions to ask yourself first

Before choosing, answer these honestly:

1. How many different systems do the numbers come from? One suggests built-in reports; three or more suggests a tool or a custom build.
2. Who will look after it in a year? If the honest answer is "nobody", avoid anything that needs regular maintenance by you.
3. Who needs to see what? If different people need different views, check role-based access carefully.
4. What happens when it is wrong? The more costly a wrong number, the less you should rely on a hand-maintained spreadsheet.
5. How often is it used? A report read once a quarter doesn't justify a build. One read every morning does.

A simple way to decide

If this describes you...	Start with
A few numbers, one person, nothing critical	A spreadsheet
All the numbers live in one product	That product's own reports
Data from several common sources and someone to build and maintain reports	An off-the-shelf reporting tool
Several systems, one with no good connector, or your own rules or roles	A custom dashboard
A bit of everything	A mix: custom screen for daily operations, a reporting tool for deeper analysis

Moving off spreadsheets without a big bang

You rarely need to switch everything at once.

1. Pick the ten questions you ask every week.
2. Move those first to a dashboard fed automatically from the real systems.
3. Keep the spreadsheet for ad hoc analysis.
4. Run both for a while and compare the numbers before you trust the new one.
5. Retire the old weekly report once people stop opening it.

Where Logic NI fits

We'll tell you honestly if a spreadsheet or a tool you already own does the job. When it doesn't, we build a dashboard around your own systems and run it as a managed service, so it stays accurate when they change. Our business dashboard service and business systems cover both routes. Talk to us or start a project. There's no obligation.
