The verdict in three sentences
A custom management platform for a real-estate agency costs 25,000 to 42,000 EUR in 2026, where real-estate SaaS charges 30 to 90 EUR/user/month. Custom makes sense once you pass 8 to 10 agents or your processes (matching, syndication, files) fall outside the SaaS boxes. The concrete gain: -30 % admin time and a controlled TCO over 4 years.
The budget module by module
Each block covers a stage of the transaction cycle, from listing to signature. Here is the 2026 order of magnitude for a mid-sized agency.
| Module | Scope | Cost 2026 (EUR) |
|---|---|---|
| Listings & property management | Records, photos, status, history | 8,000 |
| Buyer matching | Criteria, auto alerts, scoring | 5,000 |
| Multi-portal syndication | Portals, XML feeds | 4,000 |
| Signature & file | Contracts, documents, e-signature | 4,000 |
| Integration & UAT | Data import, training, API | 4,000 to 9,000 |
| Total | Full project | 25,000 to 42,000 |
Delivery runs 12 to 18 weeks, with a first listings/properties batch usable by week 8.
Real-estate SaaS or custom: the 4-year TCO
SaaS vendors bill per agent: the bill climbs fast when the agency hires. Comparison for 10 users.
| Criterion | Real-estate SaaS | Custom Kolonell |
|---|---|---|
| Upfront cost | 500 to 3,000 EUR | 25,000 to 42,000 EUR |
| Subscription (10 users) | 3,600 to 10,800 EUR/yr | 0 (hosting ~1,000 EUR/yr) |
| 4-year TCO (10 users) | 14,900 to 46,200 EUR | 29,000 to 46,000 EUR |
| Portal syndication included | Often optional | Native |
| Matching customisation | Limited | Full |
| Client database ownership | Vendor | You |
At the top tier (90 EUR/user/month), SaaS passes 46,000 EUR over 4 years: custom then becomes the economical choice while keeping your client database in-house.
Mini case study
Camille, director of a 9-agent agency in Bordeaux, juggled a 65 EUR/user/month SaaS and manual re-entry into portals. She invests 34,000 EUR in a custom tool. Admin time drops from 12 h to 8 h/week per agent, i.e. ~36 h freed/week across the agency. At 45 EUR/loaded hour, that is ~1,620 EUR/week of selling capacity returned, and the 7,020 EUR/year SaaS leaves the budget.

FAQ
How much does custom real-estate agency software cost in 2026?
Budget 25,000 to 42,000 EUR for a full tool (listings, matching, syndication, files). A listings + syndication base can start around 14,000 EUR.
Is syndication to major portals automatic?
Yes. A normalised XML feed pushes your listings to partner portals in one click, with status updates and automatic removal on sale.
Can we migrate our client database from our current SaaS?
Yes. Data migration (properties, contacts, history) is part of the integration package, priced 4,000 to 9,000 EUR by volume.
Is buyer matching truly customisable?
Yes, that is a key custom advantage: your criteria, your scoring, your alerts. SaaS imposes its rules; custom fits how you pair properties and buyers.
Who owns the client database?
You do. This is key: your buyer and seller database stays your asset, exportable any time, unlike SaaS vendor lock-in.
