What We Do

How can I tell if my spreadsheet is too complex?

When a spreadsheet stops being “just a spreadsheet”

A spreadsheet becomes a problem when it stops being a helpful tool and starts acting like a system the business relies on.

When Excel starts running the business

Here are some common signs.

1. You have more than one “latest” version

Files are emailed around, copied, renamed, or saved locally.
People are never quite sure which one is correct, so they double-check, ask around or avoid changing anything.

2. Only one person really understands it

The spreadsheet belongs to the business on paper, but in practice it belongs to one person .
If they’re off sick, on holiday or leave, everyone feels exposed.

3. The same data is typed in multiple places

Customer details, job information or dates are entered into the spreadsheet, then copied into Word documents, emails or other files, and they don’t always match.

4. You’re scared of breaking it

People avoid sorting, filtering, or changing formulas because “last time it broke something.”
The spreadsheet becomes something people work around , not with.

5. It’s slow, unstable, or increasingly unreliable

It takes longer to open.
It freezes occasionally.
It crashes just often enough to make people nervous.

6. Email is doing jobs the spreadsheet should be doing

Follow-ups, actions, and decisions live in inboxes instead of in one visible place.
Important things get missed because nobody can see them.

7. Simple questions take too long to answer

Questions like:

  • “How many active jobs do we have?”
  • “What’s overdue right now?”
  • “Who’s waiting on what?”

require manual checking instead of a quick glance.

8. Everyone agrees it’s horrible, but replacing it feels risky

The spreadsheet “works”, but everyone dislikes it.
The idea of replacing it feels like a big project, so nothing changes.

Why this matters

Once a spreadsheet reaches this point, it’s no longer just inefficient. It can start to cause real problems.

Mistakes creep in.
Decisions slow down.
Stress increases.
And the business quietly depends on something that was never designed to carry that weight.

Excel may still be the right tool for some jobs. The risk comes when one spreadsheet is expected to run an important part of the business.

A better question

The useful question is:

Is this spreadsheet running an important part of the business?

If the answer is yes, and you recognise several of the signs above, it may be worth replacing that one thing with something calmer and more reliable.

You don’t need to replace everything at once. Start with the part that is causing the most day-to-day difficulty.

A practical, low-risk way forward: the Day-1 Build

For businesses in this situation, we offer a Day-1 Build .

It’s a fixed-price one-day build to replace one spreadsheet or manual process with a live, shared system your team can start using immediately.

What happens on Day 1

  • We replace the spreadsheet with one place the team can trust
  • Your real data is imported
  • You get a simple, usable web system
  • At least one real user is using it by the end of the day

The spreadsheet stops being “the system”.

Keeping the work contained

  • The work is limited to one clear process
  • The aim is a working system, not a demo or prototype
  • There is no commitment to ongoing work

It gives you one working system without committing you to a larger project.

Is your spreadsheet a good candidate?

Not every spreadsheet should be replaced immediately.

That’s why the next step is a short call, not a sales pitch.

We look at one spreadsheet and decide whether it’s actually worth replacing right now.

If it is, we’ll explain how a Day-1 Build would work.
If it isn’t, we’ll tell you that too.

Next step

If this page feels familiar, you can book a short call here:

Is this spreadsheet worth replacing? A 15-20 minute sanity check to decide whether this is worth doing.

* I only take on a small number of Day-1 Builds at a time so I can stay hands-on. Availability is limited.

A final note

Many businesses live with spreadsheet pain for years because replacing it feels like a big, risky decision.

It doesn’t have to be. Sometimes the most valuable change is simply replacing one thing properly and seeing how it feels.
