The verdict in three sentences
A custom real estate agency tool connects mandates, listing portfolio, multi-portal syndication and buyer matching into one continuous flow. Budget 30,000 to 75,000 EUR versus 50 to 150 EUR/agent/month for a license, delivered in 14 to 20 weeks. Target gains: -12% on time-to-sale and +25% leads handled through automated matching.
Custom vs. license: the 3-year cost
Market real estate CRMs bill per agent. Beyond a certain size, custom becomes cheaper. 2026 order of magnitude.
| Option | Upfront cost | Recurring (10 agents) | 3-year cost |
|---|---|---|---|
| Standard license | 0 EUR | 50 EUR/agent/month | ~18,000 EUR |
| Premium license | 1,500 EUR | 150 EUR/agent/month | ~55,500 EUR |
| Custom Essential | 30,000 EUR | 4,500 EUR (maint.) | ~43,500 EUR |
| Custom Extended | 55,000 EUR | 8,250 EUR (maint.) | ~79,750 EUR |
| Custom Network | 75,000 EUR | 11,250 EUR (maint.) | ~108,750 EUR |
Below 6 agents, the Standard license is unbeatable. Beyond 10 agents or with specific portals and matching, custom levels off then pays back.

Mini case study
Karim, director of a 10-agent agency in Lyon, closes 180 transactions/year at 6,500 EUR average fees. His premium license costs 18,000 EUR/year and manual matching lets leads slip. He invests 55,000 EUR in a custom tool (mandates + syndication + matching + CRM) plus 8,250 EUR/year in maintenance. Handling 25% more leads and closing just 8 extra transactions per year generates 52,000 EUR in additional fees — the tool pays back in just over a year, excluding time-to-sale gains.
