The verdict in three sentences
In 2026, a SaaS real estate CRM costs 40 to 120 EUR per agent per month, while custom software runs 40,000 to 90,000 EUR over a 4-to-8-month build. Custom becomes profitable once you pass 8 to 10 active agents or when multi-portal syndication and buyer matching become your core business. Below that, renting stays wiser: you pay for flexibility, not an asset.
SaaS or custom real estate software: the real 2026 comparison
Generic platforms cover listing management and syndication well but impose limits: portal count, matching customization, exports. Custom flips the logic: you own the code, the data and the workflow.
| Criterion | SaaS real estate CRM | Custom software |
|---|---|---|
| Entry cost | 0 to 1,500 EUR setup | 40,000 to 90,000 EUR |
| Monthly cost | 40 to 120 EUR/agent | 300 to 700 EUR maintenance |
| Rollout time | 2 to 6 weeks | 4 to 8 months |
| Portal syndication | 3 to 8 included | unlimited, tailored |
| Buyer matching | fixed rules | custom scoring |
| Data ownership | vendor | agency |
| Vendor lock-in | high | none |
5-year TCO: the tipping point by agent count
The 5-year total cost of ownership depends mostly on agent count. Here is a 2026 order of magnitude for a median 80 EUR/agent/month plan against a custom project at 65,000 EUR plus 500 EUR/month maintenance.
| Number of agents | SaaS 5-year TCO | Custom 5-year TCO | Gap |
|---|---|---|---|
| 4 agents | 19,200 EUR | 95,000 EUR | +75,800 EUR SaaS wins |
| 8 agents | 38,400 EUR | 95,000 EUR | +56,600 EUR SaaS wins |
| 15 agents | 72,000 EUR | 95,000 EUR | +23,000 EUR SaaS wins |
| 25 agents | 120,000 EUR | 95,000 EUR | -25,000 EUR custom wins |
| 40 agents | 192,000 EUR | 95,000 EUR | -97,000 EUR custom wins |
The tipping point sits around 20 agents on pure cost, but arrives sooner if buyer matching wins you extra deals.

Mini case study
Thomas, director of a 3-branch network in Montreal (18 agents), paid 80 EUR/agent/month, or 17,280 EUR/year. He invests 68,000 EUR in custom software with automatic buyer-to-listing matching. The scoring wins him 3 extra mandates per year at 6,000 EUR average commission, or 18,000 EUR. Combined with subscription savings, the project pays back in under 3 years, then produces a net surplus every year.
FAQ
What minimum budget to start custom? Plan at least 40,000 EUR for a solid base (listings, contacts, syndication, matching). Below that, a 40-120 EUR/agent SaaS stays more rational.
How long to deploy? Between 4 and 8 months by scope. An MVP focused on listings and syndication can ship in 4 months, advanced modules (scoring, reporting) follow.
Can I syndicate to every portal? Yes, custom software handles unlimited syndication via standardized feeds. SaaS often caps at 3 to 8 included portals, charging extra for more.
What happens to my data if I switch vendors? With SaaS, exports are sometimes partial and migration costs 1,500 to 5,000 EUR. Custom means you own 100 % of the database and avoid lock-in.
From how many agents is custom profitable? The pure-cost threshold is around 20 agents over 5 years, but it drops to 12-15 if automatic matching improves your conversion rate.
