monday.com vs Spreadsheets: An Honest Comparison for UK Agencies
TL;DR: If more than one person needs to update it, the spreadsheet has already stopped working. Spreadsheets are fine for one-person modelling, ad hoc analysis and simple lists; they fail as shared operational infrastructure because there is no real version control, no connection to your other systems, and nothing that chases a deadline for you. monday.com fixes that, but only if it is built around how your agency actually works. Replicate your spreadsheet logic inside it and you get the cost and the learning curve without the benefit.
What are spreadsheets actually good at?
Spreadsheets are genuinely good at anything that stays with one person: financial modelling, ad hoc analysis, and simple lists nobody else needs to read or update in real time. The test is whether you are the only person who needs to touch it. If you are, the spreadsheet is the right tool and replacing it with software is overkill.
Before getting into the problems, it's worth being honest about where spreadsheets genuinely work, because understanding this helps you know when to keep using them and when to stop.
Spreadsheets are good at: one-person data management, financial modelling, ad hoc analysis, simple lists that don't need to be shared in real time, and any situation where you're the only person who needs to read and update the information.
In an agency context, that might mean budget tracking for a specific project, a quick resource allocation grid for a single campaign, or a personal task list. Nobody needs to tell you to buy a six-figure SaaS tool to manage your to-do list.
The trouble starts when you try to use spreadsheets as collaborative operational infrastructure for a growing team.
Where do spreadsheets break down in an agency?
Spreadsheets break down at the point they stop being one person's working file and become shared operational infrastructure. Five failures show up every time: version control that only exists in theory, no connection to any other system, no awareness of deadlines, a maintenance burden that grows with the team, and no way to answer a client question at a glance.
Version control is a fiction. The moment two people need to update the same spreadsheet, you've got a problem. Either you're working off a shared file and overwriting each other, or you've got local copies with no clear master. Most agencies end up with both problems simultaneously. There's "the official tracker" and then there's the tracker everyone actually uses, and nobody's quite sure which one's right.
They don't connect to anything. A spreadsheet is an island. Your client data lives in your CRM. Your time tracking is in a different tool. Your project briefs are in Google Drive. Your invoices are in Xero. The spreadsheet can't talk to any of them, which means someone is manually copying information between systems. That person is making mistakes, and they hate that job.
They have no intelligence about deadlines. A cell can contain a date. But a spreadsheet won't email your project manager when a deadline is three days away, flag when a task has been sitting unactioned for two weeks, or automatically move a project to a new stage when all the subtasks are complete. You have to do all of that manually, which means a lot of it doesn't happen.
They don't scale with your team. A 20-row spreadsheet is manageable. A 200-row spreadsheet with 15 contributors, colour-coded by department, with three separate tabs that don't quite link up is a full-time job to maintain. At a certain point the spreadsheet stops being a tool that helps you do your job and becomes a job in itself.
You can't see the wood for the trees. When a client asks where you're up to on a campaign, can you answer immediately from your spreadsheet? Or do you have to find the right tab, scroll to the right row, work out what the status abbreviation means, and then cross-reference with the Slack thread where someone said something had changed last Tuesday? monday.com gives you a live dashboard. The spreadsheet gives you a puzzle.
What does monday.com actually do better than a spreadsheet?
monday.com does four things a spreadsheet cannot: real-time collaboration with one version of the truth, automations that chase deadlines and status changes on their own, dashboards that answer capacity and pipeline questions instantly, and integrations that move data between your CRM, email and billing without anyone copying it across. The work still gets done by people. The difference is that nothing slips because somebody forgot to chase it.
There are four things monday.com does materially better than spreadsheets for agencies operating above a certain size.
Real-time collaboration without chaos. One version of the truth, always up to date, accessible to the right people with the right permissions. No more "which one's the latest file" conversations.
Automations that do the chasing. Deadline notifications, status updates, task assignments, client updates: all triggered automatically based on rules you define. The work still gets done by humans. monday.com just makes sure nothing slips through because someone forgot to chase it.
Dashboards that answer questions instantly. Capacity by team member. Pipeline value by client. Delivery status across all active projects. These views take minutes to build in monday.com and hours to maintain in a spreadsheet.
Integrations that join the dots. monday.com connects to your CRM, your email, your Slack, your time tracking, your billing. Data flows between systems. The manual copy-paste work goes away.
The honest caveat
monday.com is not magic. If you implement it badly, if you just replicate your spreadsheet logic inside a different tool, you'll get all the downsides of a new system (learning curve, change management, cost) without getting the benefits.
The agencies that switch from spreadsheets to monday.com and find it doesn't work are almost always the ones that did it themselves, quickly, without proper thought about how the tool should be structured. The ones that do it properly, with a clear workflow map, a sensible board structure, and a real adoption plan, typically wonder why they waited so long.
If you're still on spreadsheets and wondering whether it's time to move, the answer is probably yes. The question is whether you want to do it in a way that actually works.
