CRM vs Spreadsheet for Property Developers: An Honest Comparison
Plenty of small developers run their first project entirely on spreadsheets, and for a handful of units with one sales person, that can work fine. The question is not whether a spreadsheet can technically track a sale, it is at what point the cost of using one starts outweighing the cost of a proper CRM. This comparison sets out where that line usually sits.
Where spreadsheets genuinely work
For a very small project, perhaps under 10 units with a single person handling sales, a well-organised spreadsheet can track leads, reservations and basic status without much friction. The overhead of learning and paying for a CRM may not be worth it at that scale, particularly if there is no agency network involved and no need for buyers to see live availability online.
The moment any of those conditions change, the balance shifts quickly, and most developers find that out the hard way partway through their first larger project.
Where spreadsheets start to break down
The first failure point is usually version control. Once more than one person needs to update unit status, whether that is a sales colleague, an assistant, or an agency partner, spreadsheets create conflicting versions, and someone eventually sells a unit that was already reserved by someone else.
- Multiple people editing the same file leads to overwritten or conflicting data
- No automatic sync between the spreadsheet and your public website
- No audit trail of who changed what and when
- Document management becomes a separate, disconnected folder structure
- Reporting requires manual pivot tables that go stale the moment the sheet is updated
The real cost of a double-sold unit
The clearest case for moving off spreadsheets is the risk of double-selling a unit, which happens when two people update different copies of the same file or when an agency was not told a unit went under offer. Beyond the immediate awkwardness, this damages trust with both the buyer and the agency, and resolving it can cost more sales time than a year of CRM licence fees would have cost in the first place.
Even short of a double sale, the time spent manually reconciling spreadsheet versions, chasing agencies for updates, and rebuilding status reports by hand adds up across a project and is rarely accounted for when people compare 'free spreadsheet' against 'paid CRM'.
What a CRM adds beyond tracking
A CRM is not just a spreadsheet with a nicer interface. It adds live availability that updates automatically, permissioned access for agency partners, document storage tied directly to each unit and deal, and lead qualification that a static spreadsheet simply cannot do.
It also tends to improve the buyer experience, since sales staff working from a single live system can answer availability and pricing questions immediately rather than needing to check with someone else first.
A practical decision point
A reasonable rule of thumb is to move to a dedicated CRM once you have more than one person updating sales data, more than a handful of units, or any agency partners involved in selling the project. Below that, a spreadsheet may still be adequate, but it is worth revisiting the decision at the start of every new project rather than assuming last year's approach still fits.
Making the switch without disruption
If you decide to move off spreadsheets, the easiest time to do it is at the start of a new project launch rather than mid-sale. Prompto's CRM is priced per unit per year, starting at 35 EUR for the marketing pack, which for most projects costs less than the sales time lost to a single double-booked unit, while also giving agency partners live access to availability and documents from day one.
Frequently asked questions
At what project size does a spreadsheet stop being enough?
A reasonable threshold is once more than one person updates sales data, you involve any agency partners, or your unit count grows beyond what one person can track reliably by hand.
What is the biggest risk of running sales on a spreadsheet?
Double-selling a unit because two people worked from different versions of the file, which costs far more in lost trust and sales time than a CRM licence would.
Can a spreadsheet sync with a public website showing availability?
Not reliably. Spreadsheets have no built-in way to push live status updates to a website, which is one of the main reasons developers move to a dedicated CRM.
Is switching from a spreadsheet to a CRM disruptive?
It is easiest at the start of a new project launch, since the sales team can begin using the new system from the first lead rather than migrating data mid-sale.
