A spreadsheet that runs part of your business is never as cheap as it looks. The licence costs next to nothing, but the hours spent keeping it up to date, the errors that slip through, and the risk of one person being the only one who understands it are all real costs - they just don't show up on an invoice. The good news is you can work out roughly what yours costs in an afternoon, and that tells you whether it's time to replace it.
Why spreadsheets become a problem
Spreadsheets are brilliant tools. Most businesses start with them for good reason: they're flexible, everyone knows how to use them, and you can build something useful in an hour. The trouble starts when a spreadsheet quietly becomes a system - the place where orders are tracked, jobs are costed or stock is counted.
You've probably seen the signs:
- Several versions of the same file, and nobody is sure which one is current
- A workbook with dozens of tabs and formulas only one person understands
- Customer or product data copied between files by hand
- Monthly reports that take days to pull together because the numbers live in different places
- Staff re-keying the same information into the spreadsheet and then into Xero or MYOB
None of this is anyone's fault. It's what happens when a business grows faster than its tools. But at some point the spreadsheet stops saving time and starts costing it. We cover the warning signs in more detail in signs your business has outgrown spreadsheets.
How to work out what your spreadsheet really costs
You don't need a consultant to do this. Pick your most important spreadsheet - the one that would cause the most pain if it disappeared - and work through these steps:
- List everyone who touches it in a normal week.
- Ask each person to estimate how much time they spend updating, checking, fixing or explaining it.
- Multiply those hours by a realistic hourly cost for each person, including super and overheads, not just their wage.
- Multiply by the number of working weeks in a year.
That's your direct cost. For example, if three people each spend a couple of hours a week maintaining an order-tracking workbook, that's a meaningful chunk of paid time every year spent on keeping a file alive rather than serving customers.
Then add the costs that are harder to measure:
- Errors. A broken formula, a pasted-over row or a wrong version can lead to a wrong quote, a missed invoice or a stock shortfall. Think about the last time something went wrong and what it cost to fix.
- Delay. If the numbers you need for a decision take a week to compile, you're making decisions on old information.
- Key-person risk. If the person who built the spreadsheet leaves or is off sick, who can keep it running?
- Lost data. Accidental deletion, a corrupted file or someone working on an old copy can wipe out work.
You won't get a precise figure, and you don't need one. You need a rough number that's honest enough to compare against the cost of fixing the problem.
What to do about it
Replacing a spreadsheet doesn't always mean buying a big new system. Depending on what the spreadsheet does, the right answer might be one of these:
- Use the system you already have properly. Many businesses track things in Excel that Xero, MYOB or their job management software can already do. Sometimes the fix is configuration and training.
- Connect your existing systems. If the spreadsheet exists only to move data from one system to another, an integration can do that job automatically. See eliminating double data entry.
- Automate the routine steps. Approvals, reminders, data imports and report generation can often be automated with business process automation while you keep the tools your team knows.
- Build something small and specific. When no off-the-shelf product fits, a simple custom tool built around how you actually work can replace the spreadsheet without forcing you into a large system.
The right choice depends on what the spreadsheet is doing, how many people rely on it and what other systems it touches. Our page on when Excel isn't enough for your business walks through the options.
Keep the spreadsheets that work
Not every spreadsheet needs replacing. A one-off analysis, a personal budget model or a quick calculation is exactly what Excel is for. The ones worth looking at are the spreadsheets that:
- Several people rely on every day
- Hold data that also lives in another system
- Feed into invoicing, payroll, ordering or financial reporting
- Would cause real damage if they were wrong or lost
Start with the one that scores worst on that list. Fix it, see how it goes, then move to the next.
Frequently asked questions
How do I know if a spreadsheet has become a business risk?
If several people depend on it daily, if it holds data that should be in your accounting or job system, or if only one person really understands it, it's a risk worth addressing.
Is it expensive to replace a spreadsheet with a proper system?
It depends on what the spreadsheet does. Sometimes the answer is using features you already pay for; sometimes it's an integration or a small custom tool. Costs vary widely depending on the size of the business, how many systems are involved and how much needs to be custom-built - so we scope every project first and give you a fixed quote after a free initial chat.
Can I connect a spreadsheet to Xero or MYOB instead of replacing it?
Yes, in some cases. Both Xero and MYOB have APIs, so data can be pulled into or pushed from a structured spreadsheet or database. It's often a good interim step, but it works best when the spreadsheet has a consistent layout.
What should I fix first?
The spreadsheet that would hurt most if it broke tomorrow - usually the one that feeds invoicing, ordering or job costing.
