For all the systems, platforms, and tools now available, spreadsheets are still running most SMEs.
- Finance relies on them.
- Operations depends on them.
- Sales and procurement often build their own versions.
Even in businesses that have invested in ERP, accounting software, or CRM systems, spreadsheets quietly sit underneath everything, holding the logic, the reconciliations, and often the answers.
This isn’t because SME leaders are behind the curve. It’s because spreadsheets genuinely solve problems, at least initially.
The risk appears later.
Why spreadsheets persist in growing SMEs
Spreadsheets survive because they are effective in the early stages of growth.
- They are familiar.
- Almost everyone knows how to use them.
- No training required.
They are flexible.You can build what you need, when you need it, without waiting for IT or system changes.
They offer a sense of control. When the spreadsheet is yours, you understand how the numbers are built and you can adjust them quickly.
And they feel cost-effective.
No licence fees. No implementation projects. No disruption.
For a long time, spreadsheets feel like the sensible choice.
This pattern is especially common in growing SMEs where systems have evolved faster than reporting practices.
When strengths quietly become weaknesses
The problem is not spreadsheets themselves. It’s what happens as the business grows around them.
- As transaction volumes increase, spreadsheets become harder to maintain.
- As teams expand, multiple versions appear.
- As decisions become more time-critical, manual processes slow everything down.
What once felt flexible starts to feel fragile. This is often where the hidden costs of disconnected data begin to surface, with time and effort absorbed by reconciliation rather than improving performance.
Small changes introduce errors. Manual reconciliations become routine. Confidence in the numbers starts to erode.
At this point, spreadsheets are no longer supporting the business.
They are holding it together.
The hidden risks most SMEs don’t see
The risks of spreadsheet dependency are rarely obvious at first.
One is dependency on individuals.
Often only one or two people truly understand how key spreadsheets work. Knowledge lives in personal files and individual logic, not in the business.
Another is loss of trust.
When numbers regularly need explaining or correcting, leaders hesitate. Decisions slow down, not because people are cautious, but because the data feels unreliable.
There is also scaling risk.
Spreadsheets don’t scale gracefully. What worked at £5m revenue often becomes unmanageable at £15m, even if the spreadsheet still technically works.
These risks accumulate quietly, until control starts to feel harder than it should.
Why replacing spreadsheets outright rarely works
Many SMEs respond by trying to remove spreadsheets altogether. This usually fails.
Spreadsheets exist because they fill gaps. They adapt quickly. They answer questions systems were never designed to answer.
The issue is not removing spreadsheets. Good data foundations focus on reducing dependency rather than eliminating tools, something we explored in what good data foundations actually look like in an SME.
It’s reducing what the business relies on them for.
Good data foundations don’t eliminate spreadsheets. They reduce dependency by:
- Making core reporting repeatable and consistent
- Ensuring key numbers come from trusted sources
- Allowing spreadsheets to be used for analysis, not as the system of record
This shift preserves flexibility without accepting fragility. Reducing dependency usually means giving teams a clearer, shared view of performance without removing flexibility altogether.
From control to confidence
Spreadsheets give a sense of control. Good data foundations provide confidence.
- Confidence that the numbers are right.
- Confidence that decisions are based on the same view across teams.
- Confidence that the business can grow without increasing risk.
For most SMEs, spreadsheets aren’t the problem.
Relying on them to run the business is.
Recognising where that line sits is often the first step towards regaining control as the business scales.
