The verdict in three sentences
In 2026, a custom real-estate agency platform costs between 35,000 and 90,000 EUR, versus 1,200 to 6,000 EUR per year per user for an off-the-shelf real estate tool. Custom wins when the agency has more than 8 agents, several brands or an atypical model (new build, network, life-annuity). The decisive metric remains the mandate conversion rate, which automatic matching improves.
Off-the-shelf or custom: when to switch
Off-the-shelf real estate tools are excellent for a standard agency: mandates, prospecting, portal syndication, CRM. Custom is justified beyond a certain size or for a proprietary process. 2026 order of magnitude.
| Criterion | Off-the-shelf tool | Kolonell custom |
|---|---|---|
| Year 1 cost (10 users) | 12,000 - 60,000 EUR | 35,000 - 90,000 EUR |
| Recurring cost/year | 12,000 - 60,000 EUR | 6,000 - 15,000 EUR |
| Time to deploy | 2 - 6 weeks | 3 - 6 months |
| Portal syndication | Included | Included (portal API) |
| Buyer matching | Standard | Custom, scoring |
| Multi-brand | Often paid option | Native |
| Code ownership | No | Yes |
Over three years, an off-the-shelf tool for 10 agents (36,000 EUR/year) costs 108,000 EUR in subscription. Custom at 65,000 EUR plus 10,000 EUR/year reaches 95,000 EUR and becomes an owned asset that does not grow with each new agent.
Portal syndication and matching: the two engines
An agency's value lies in the speed of connecting the right property to the right buyer. Here are the quantified levers of a well-designed tool.
| Lever | 2026 impact (order of magnitude) |
|---|---|
| Automatic multi-portal syndication | -2 to -4 h/week/agent |
| Buyer matching by scoring | +10 to +18% relevant matches |
| Automatic buyer follow-up | +5 to +9% viewings |
| Mandate pipeline tracking | Conversion +3 to +6 pts |
| Electronic mandate signature | -3 to -7 days per mandate |
| Real-time manager reporting | Targeted prospecting decision |
For an agency closing 120 sales/year at 6,500 EUR average fees, gaining 4 conversion points represents roughly 31,000 EUR of additional commission per year.

A good real estate CRM does more than store contacts: it triggers the right follow-ups, computes buyer scoring and alerts when a new property matches a saved search. That is where custom pulls ahead, fitting the agency's exact process.
Mini case study
Sarah runs a 3-agency network in Bordeaux, 14 agents, 155 sales/year, 7,200 EUR average fees. Her mandate conversion rate is 41%. By reaching 46% through matching and automatic follow-ups, she closes about 19 more sales, i.e. 136,800 EUR/year of additional fees. Her custom build at 72,000 EUR plus 11,000 EUR/year pays back in under 7 months.
FAQ
Is portal syndication automatic? Yes, via the major portals' APIs, a single entry publishes to all channels. This eliminates re-keying and errors in price or photos.
Can we keep our working habits? That is exactly custom's strength: the software fits your prospecting, mandate and follow-up process, not the other way around. We frame these business rules from the design workshop.
Is buyer matching reliable? Scoring combines criteria, budget, viewing history and behavior. It does not replace the agent but wins them 10 to 18% more relevant matches.
What does adding an agent cost? In custom development, nothing: the code is owned, there is no per-user license. That is the major gap with market subscriptions beyond 10 seats.
What is the deployment timeline? Expect 3 to 6 months depending on modules, with a first go-live of the CRM and syndication from week 8 to 10.
