How much does a custom CRM cost for an SME?
Published on
It is almost always the first question, and the honest answer is that it depends on specific things rather than on the size of your company. A CRM for a team of three can cost more than one for twenty if the process behind those three is more complex. Here is what actually moves the number.
What genuinely makes a CRM expensive
The price is rarely driven by user count. It is driven by three things: how many integrations it needs, how much automatic logic sits behind it, and how many edge cases it has to handle.
An integration is any point where the CRM talks to another system: your website, WhatsApp, calendars, payment providers, accounting tools. Each one adds work, because you have to handle what happens when that system fails or changes. Automatic logic is everything that happens without anyone clicking: routing a lead to the right person, sending a reminder 24 hours ahead, flagging an opportunity that has sat still for five days.
Edge cases are the most expensive and the least visible at the start. "Clients of this type pay on 60 days", "quotes above X need sign-off", "no reminders in August". Every exception is logic that has to be built and tested.
Custom build versus monthly licence
A subscription platform has a low entry cost that grows with your team: you pay per user per month, indefinitely. A custom system has a higher upfront cost and then significantly lower maintenance, with no per-seat licence.
Which wins depends on how long you plan to use it and how closely your process matches the industry standard. If your business works the way the textbook says, an off-the-shelf platform is probably the sensible choice and we will tell you so. If you have spent years fighting a tool to make it do something it was never designed for, that is where custom wins.
One caveat: the cost of a standard platform is not just the licence. Add the hours your team loses adapting to a workflow that is not theirs, and the add-on modules you end up buying to plug the gaps.
How to know if it pays off
There is a simple calculation you can do today. Estimate how many hours a week your team spends moving data between systems: copying an email into a spreadsheet, transferring a WhatsApp message into a record, rebuilding a report by hand. Multiply by your hourly cost and by 48 weeks.
That number usually surprises people. If it comes out below a few thousand euro a year, you probably do not need a custom CRM yet and something standard will do. If it comes out well above, the system pays for itself within months.
The second calculation is about leads going cold. If you know how many enquiries you get monthly and what share end up with no reply or a late one, you already have an estimate of what a lack of automated follow-up costs you.
What to ask before hiring anyone
Always ask for the quote to separate build from maintenance. A single figure with no breakdown hides surprises.
Ask who owns the code and who owns the data. If the answer is not "you", you are renting rather than buying, and that changes the price comparison entirely.
And ask for a timeline in writing before signing. A supplier who cannot give you an approximate date after understanding your process probably has not understood it.
