Why Hire an Excel Consultant? 7 Ways They Save You Time and Money
There's a moment most businesses experience with Excel.
You've been managing fine.
Your spreadsheets work (mostly).
Your team knows enough to get by.
Then something changes…
Maybe your data has grown too complex.
Maybe you're spending hours on tasks that should take minutes.
Maybe that "quick fix" from three years ago is now holding your entire operation together like a house of cards.
And you start wondering: should we actually get help with this?
The DIY Excel Trap
I get it. Excel feels like something you should be able to figure out yourself.
It's just spreadsheets, right? How hard can it be?
But the reality is the cost of figuring it out yourself is almost always higher than the cost of getting expert help.
Not just in money. In time, frustration, missed opportunities, and solutions that sort of work but never quite do what you need.
So if you're wondering whether hiring an Excel consultant makes sense for your business, here are 7 ways they actually save you time and money:
1. They Solve Problems Faster
When you're stuck on an Excel problem, how long do you spend trying to fix it?
An hour? A morning? A full day of Googling, ChatGPT-ing (is this a verb yet?), trial and error, and frustration?
An Excel consultant can often diagnose and solve the same problem in minutes.
Not because they're geniuses or smarter than you.
Because they've seen it before.
Pattern Recognition
After years of working with Excel across different businesses and industries, consultants develop pattern recognition.
They've encountered your problem (or something very similar) dozens of times.
They know the common causes, the likely solutions, and the edge cases that might trip you up.
What feels like a unique, impossible challenge to you is often a familiar scenario to them.
The Real Cost of DIY
Let's say you spend 4 hours trying to fix a formula issue.
If your time is worth £50/hour, that's £200 of your time.
A consultant might solve it in 30 minutes.
Even if they charge £150 - you’re still better off.
You've saved money, saved time, and avoided the frustration of banging your head against a problem you're not equipped to solve.
Speed Compounds
It's not just about solving one problem faster.
When you know someone can quickly fix Excel issues, you stop avoiding them.
You stop building workarounds.
You stop accepting "good enough."
You actually fix the problems, which means your systems work better, your team wastes less time, and your business runs more smoothly.
2. They Build It Right the First Time
(This section only applies if they’re actually a good consultant….)
Here's a common scenario:
A business builds an Excel solution that works for their current needs.
Six months later, the business grows. The data doubles. The requirements change.
And suddenly, the solution doesn't work anymore.
So they patch it. Add more formulas. Create workarounds. Build on top of the original structure.
Eventually, they end up with a Frankenstein spreadsheet that's slow, confusing, and impossible to maintain.
The Rebuild Cost
Now they need to start over.
But they can't just rebuild it - they need to migrate existing data, retrain their team, and somehow keep the business running while they transition.
What started as a "quick Excel solution" has now cost them weeks of work and thousands in lost productivity.
Building for Scale
An Excel consultant doesn't focus on only solving today's problem.
They build solutions that account for:
Future growth (what happens when you have 10x the data?)
Team changes (what if the person who built it leaves?)
New requirements (how easily can this adapt?)
Performance (will this still work fast when it's bigger?)
They're thinking about the next 2-3 years, not just the next 2-3 weeks.
And they will (or should be) honest about the life-span of the solution they provide, for example “Yes, this works to track 10,000 customers in the system and after that, we will need to look at something else”
At least you know where you stand and can plan ahead.
The First-Time-Right Premium
Yes, hiring a consultant upfront costs more than doing it yourself.
But rebuilding a solution costs even more.
Especially when you factor in the disruption, the data migration headaches, and the opportunity cost of your team spending weeks fixing something that should have been built properly from the start.
Even if you exclude the quality aspect, building it right first time avoids the expensive rebuild mistake.
3. They See Solutions You Don't
When you're deep in your own business, you develop tunnel vision.
You know your processes inside out.
You know how things have always been done.
You know what "everyone does."
And that familiarity can blind you to better approaches.
The Fresh Perspective Advantage
An Excel consultant comes in with fresh eyes.
They're not attached to "how we've always done it."
They're not constrained by your assumptions about what's possible.
They ask questions like:
"Why are you doing it this way?"
"Have you considered this alternative approach?"
"What if we restructured the data like this instead?"
Sometimes the answer is "because that's the best way."
But often, it's "because we didn't know there was another option."
Cross-Industry Experience
When working with a consultant, you get access to the knowledge they’ve acquired working with multiple businesses.
You see patterns and solutions that work across different industries.
A technique they learnt solving a Logistics problem might be perfect for a Finance challenge.
An approach that works brilliantly for a 10-person team might scale beautifully for a 50-person operation.
You're not just getting base Excel knowledge - you're getting insights from dozens of other businesses and industries.
The "I Didn't Know That Was Possible" Moment
Some of my favourite conversations start with:
"I didn't know Excel could do that."
Because they've been working within the boundaries of what they know, not what's actually possible.
A consultant expands those boundaries.
Some of my favourite projects - which are stories for another time are:
Image based language learning app in 10 languages
Airline Manager 4 fleet manager tool and game simulation
Cooking helper (telling you how long to cook things that need different times and temperatures in the same oven and when to turn)
These all taught me very transferrable skills to build a CRM, or Financial report, etc.
And you get access to those experiences to expand those boundaries you thought of what was possible when working with me.
4. They Save Your Team's Time
Usually when a business tries to solve an Excel issue someone on the team gets volunteered (or volunteers) to "figure it out."
This person already has a full-time job.
But now they're also the unofficial Excel expert, spending hours researching, building, and troubleshooting.
Their actual work gets pushed aside.
Deadlines slip.
Other priorities suffer.
And the Excel project takes three times longer than it should because they're learning as they go.
The Opportunity Cost
Let's say you have a team member earning £35,000/year.
That's roughly £17/hour.
If they spend 20 hours building an Excel solution, that's £340 of their time.
But that’s not the full cost: what didn't get done during those 20 hours?
The client follow-ups that didn't happen.
The project that got delayed.
The strategic work that got pushed to next week.
As is my usual rant, there’s a real difference between Direct and Indirect hours on the Finance Report and just because you’re paying someone’s salaries, doesn’t mean them solving issues outside their job description is “saving money”.
Let Your Team Do Their Jobs
Your Logistics Coordinator should be coordinating logistics.
Your Finance Manager should be managing finances.
Your Operations Lead should be leading operations.
Not spending days trying to figure out why their VLOOKUP keeps returning #N/A.
When you hire a consultant, your team stays focused on what they're actually good at - and what you're actually paying them to do.
The Speed Difference
A task that takes your team member 20 hours might take a consultant 4 hours.
Not because your team isn't capable, but because the consultant has done it dozens of times before.
Your team gets their solution faster, and they never had to stop doing their actual job.
5. They Future-Proof Your Solutions
Most businesses build Excel solutions for right now.
They solve today's problem with today's data and today's team.
But businesses change.
Your data grows.
Your team expands.
Your processes evolve.
Your requirements shift.
And suddenly, the solution that worked perfectly six months ago is creaking under the pressure.
Building for Tomorrow
A good consultant doesn't just ask "what do you need this to do?"
They ask:
"How much is your data likely to grow in the next 2 years?"
"Who else might need to use this in future?"
"What other requirements might come up down the line?"
"How will this integrate with other systems you're planning?"
They're building solutions that can adapt and scale, not just work for today.
Maintainability Matters
A question that’s often overlooked with any new process or system being implemented is: “who in your business is going to own this solution?”
Not just use it - but understand it, maintain it, and adapt it when needed.
A good consultant doesn't just hand you a finished spreadsheet and disappear.
They build solutions that your team can actually work with.
Clear structure.
Logical flow.
Documentation that explains the why, not just the what.
And ideally, they involve someone from your team in the process - so there's at least one person internally who understands how it works and can make small changes without calling for help every time.
Because if no one in your business understands the solution, you haven't gained independence - you've just created a new dependency.
The goal isn't to make you reliant on the consultant forever (for some it is…)
It's to give you a solution your team can own, maintain, and evolve as your business grows.
The Scalability Question
I always have a conversation with clients about scalability limits.
"This solution will work brilliantly up to about 50,000 rows. After that, we'll need to look at a database."
"This handles 5 users comfortably. If you're planning to scale to 20 users, we should build it differently."
I'd rather be honest upfront about limitations than have you hit a wall 18 months from now.
6. They Transfer Knowledge
The best consultants don't just solve your problem and leave.
They teach you something in the process.
Training as Part of the Solution
When I deliver a solution to a client, I don't just hand over a spreadsheet with a "good luck."
I walk them through:
How it works and why it's built that way
What to do if something goes wrong
How to make common modifications themselves
When to call for help vs when they can handle it
The goal is to make them more capable, not more dependent.
Documentation That Actually Helps
We give clients the option to have Help Files with their solutions.
Not technical jargon that no one reads.
Not a long word document that’s a pain to find what you’re looking for.
It’s an interactive PowerPoint file where you click on different aspects (screenshots of the system) to find what you’re looking for.
Practical, plain-English guides that explain:
"Here's what this section does"
"Here's how to add a new category"
“Here’s where this data is coming from”
"Here's what to check if you get an error”
“Here are related sections you may want to check out”
Because three months from now, when the person I trained has moved to a different role, someone else needs to be able to figure it out.
Building Internal Capability
Every project is an opportunity to upskill your team.
The person who works with me on a project learns techniques they can apply elsewhere.
They see how to structure data better.
How to think about automation.
How to troubleshoot issues.
That knowledge doesn't leave when I do - it stays with your business.
The Teach a Person to Fish Approach
You could hire a consultant every time you have an Excel problem.
Or you could hire a consultant who teaches your team to solve 80% of problems themselves - and only call for the complex 20%.
That's the approach I prefer.
I think your team should feel confident in the solution they now have and their capability to handle things.
7. They Cost Less Than You Think
When people hear "hire a consultant," they often assume it's expensive.
And yes, consultants aren't free.
But expensive compared to what?
The Software Subscription Comparison
Many businesses pay £50-£200/month for software subscriptions.
That's £600-£2,400/year. Every year. Forever.
A bespoke Excel solution might cost £1,500-£3,000 upfront.
But then it's yours.
No ongoing subscription.
No per-user fees.
No annual price increases.
Over 2-3 years, the Excel solution is often significantly cheaper - and it's built exactly for your needs, not a generic template you have to adapt to.
The Staff Time Comparison
We covered this earlier, but it's worth repeating:
If your team member earning £35,000/year spends 40 hours building and troubleshooting an Excel solution, that's £680 of their time.
A consultant might do it in 8 hours for £700.
Similar cost... But your team member never stopped doing their actual job, and the solution is built properly from the start.
The Rebuild Cost Comparison
Building something yourself that doesn't scale: £500 in time
Rebuilding it 12 months later when it breaks: £800 in time
Migrating data and retraining the team: £400 in time
Total: £1,700
Building it right the first time with a consultant: £1,200
The "cheap" option ends up costing more.
The Peace of Mind Factor
There's also a value to knowing something is done properly.
No more patching and workarounds.
No more hoping the one person who understands it doesn't leave.
No more worrying if your critical spreadsheet will break at the worst possible moment.
That peace of mind has a value too - even if it's harder to put a number on it.
So, Should You Hire an Excel Consultant?
Here's the honest answer: it depends.
If you're dealing with a simple, one-off task that you can figure out in an hour - probably not.
But if you're facing any of these situations:
Your team is spending significant time on Excel problems
You need a solution that will scale with your business
You've built something that's now breaking under pressure
You're paying for expensive software when Excel could do the job
You need expertise you don't have in-house
Then yes, hiring a consultant probably makes sense.
The Real Question
It's not "can we afford to hire a consultant?"
It's "can we afford not to?"
When you factor in the time saved, the mistakes avoided, the solutions built properly, and the knowledge transferred to your team - the ROI is usually pretty clear.
