In almost every B2B SME I step into, there’s one file. Just one. It’s called something like `suivi_clients_2024_V3_FINAL(really).xlsx`, it has fifteen tabs, and only one person truly knows how it works. When she’s on leave, the entire team holds its breath.
Excel is great. It’s often the right choice to start with: free, flexible, and everyone knows how to use it. The problem isn’t Excel—it’s when your business outgrows it without anyone noticing. Here are five signs that, when I hear them in meetings, mean the same thing: it’s time to switch to a real industry-specific software.
1. Multiple people need to edit the same file at the same time
This is the classic scenario. Two salespeople open the tracking file, each on their own, and by evening, you have to ‘merge’—meaning someone manually copies the other’s lines, hoping nothing gets missed. Or the file is on a shared drive, and you start seeing copies like `- Copy`, `- modified by Julie`, `- do not use`.
An Excel file was never designed to be a multi-user database. As soon as multiple hands start writing in it, you’re no longer working with data—you’re working with versions. A dedicated software solution, on the other hand, assumes that ten people are writing simultaneously, and that the data remains single and consistent.
2. You spend more time fixing than producing
A client billed twice. An order slipped through because it was on the next tab. A total that doesn’t add up, and no one knows why. If your team spends Friday afternoons ‘checking that everything’s okay,’ it’s not a discipline issue—it’s a structural problem.
Excel lets you write anything, including nonsense. A tailored tool puts safeguards where they matter: you can’t validate an order without a client, you can’t bill the same service twice, and a status can’t be both ‘paid’ and ‘pending’ at the same time. These invisible constraints eliminate errors at the source.
3. ‘That? It’s in Marc’s file’
When I ask where a piece of information is, and someone replies, ‘Oh, that’s Marc’s thing—it’s in his file,’ I know the company operates in silos. Sales tracking here, production there, invoicing in a third spreadsheet, and between them, copy-pasting and emails with attachments.
The cost of these silos is invisible but real: no one has the full picture, the same data gets entered three times, and when Marc leaves, part of the company’s memory leaves with him. A dedicated software solution brings all these pieces together in one place, where everyone sees what concerns them without having to ask.
4. There’s a formula no one dares touch
In every big Excel file, there’s the cell. A sprawling formula, written three years ago by someone who may no longer be there, that everything else depends on. No one truly understands it, so no one touches it—you just build around it, crossing your fingers.
It’s technical debt, exactly like in software, except it’s hidden in a spreadsheet, and the day it breaks, it breaks everything. When a company reaches this point, it’s the clearest sign that its tool has become more fragile than its business can afford.
5. You can’t answer a simple question in ten seconds
'How much have we billed this client since January?' 'Which orders are delayed?' 'Which salesperson signed what this quarter?' If the answer to these questions is ‘Give me an hour, I’ll make a pivot table,’ you don’t have a management tool—you have an archive.
A B2B industry-specific software solution is first and foremost about this: being able to ask a question about your business and getting the answer instantly. Not once a month when someone has time to compile it, but on demand, up-to-date, for everyone.
Crossing the threshold without breaking everything
The good news is that you don’t replace ten years of Excel in one weekend, and especially, you don’t have to. My approach is simple: start with the file that hurts the most, the one everything else depends on, and replace it with a tool that does exactly what it did—better, safer, and for multiple users. The rest follows, step by step, once trust is established.
I always give you an honest budget estimate from the first exchange, and a rule I stick to: if your Excel is still doing the job, I’ll tell you. Switching to a specialized software should save you time and stress, not sell you a project you don’t need.
FAQ
Is custom software only for big companies?
No. B2B SMEs often suffer the most from Excel’s limitations because they’ve grown faster than their tools. We size the software to your actual needs, not your company size.
How long does it take to replace our main file?
A first version that replicates the role of your most critical file can be live in a few weeks. We then progress in small increments, never disrupting operations.
Will we lose our Excel data when migrating?
No, quite the opposite: we start with your existing files to initialize the software. Your history is preserved, not discarded.
What if we just want to better organize our files, not a full software?
That’s a valid option, and I’ll let you know if that’s your case. Sometimes, a few automations are enough before considering real development.
If one or two of these signs made you wince, now’s the time to talk. I always start with an audit of your organization and a written action plan—you leave with a clear vision, even if you decide to move forward without me later.
