The verdict in three sentences
The crux for an agency is not the stock of listings but the speed of matching a property with the right buyer. A transaction SaaS (50-150 EUR/month/user) covers multi-portal syndication and standard CRM, ideal to start fast. Custom (20,000-60,000 EUR) is justified as soon as you want fine buyer matching, a specific listing process or integration with your other tools.
SaaS or custom: the right trade-off
SaaS wins on time-to-market and entry cost. Custom wins on differentiation and data ownership as the agency grows.
| Criterion | Transaction SaaS | Custom |
|---|---|---|
| SeLoger / Leboncoin syndication | Yes, standard | Yes, via API |
| Buyer matching | Basic | Advanced scoring |
| Listing management | Standard | Your process |
| Data ownership | Vendor | Agency |
| 2026 cost | 50-150 EUR/month/user | 20,000-60,000 EUR one-off |
| Timeline | Immediate | 8-14 weeks |
ROI of syndication and matching
The gain is measured in shortened time-to-sell and better-exploited buyer leads. Each listing sold faster improves cash flow and stock rotation.
| Item | 2026 range | Comment |
|---|---|---|
| SaaS (5 users) | 3,000-9,000 EUR/yr | 50-150 EUR × 5 × 12 |
| Custom development | 20,000-60,000 EUR | 8-14 weeks |
| Multi-portal connectors | 3,000-8,000 EUR | SeLoger, Leboncoin, etc. |
| Client/listing migration | 2,000-6,000 EUR | Volume and quality |
| Recovered buyer leads | +20-30% exploited | 2026 estimate |
Mini case study
Karim runs a 5-agent agency in Nice closing about 30 sales a year at 6,500 EUR average fees, i.e. 195,000 EUR of annual commissions. Better buyer matching lets him close 4 extra sales a year, i.e. 26,000 EUR of additional commissions. A custom development at 40,000 EUR therefore pays back in under 20 months, then generates recurring net gain, on top of stock that turns faster.

Is SaaS enough for a small agency?
Often yes, to start. Below 5 agents with a standard process, a transaction SaaS at 50-150 EUR/month/user covers the essentials; custom becomes worthwhile with volume and differentiation.
Is multi-portal syndication automatic?
Yes, we connect SeLoger, Leboncoin and other portals via API to publish a listing once and syndicate it everywhere, without re-keying.
How does buyer matching work?
The system cross-references a new listing's criteria with the buyer database and surfaces the best matches, with scoring we refine for your Nice market.
Who owns the data with custom?
You do. It is a key advantage of custom: your listing and buyer database belongs to you, with no vendor lock-in.
What timeline for custom?
Expect 8 to 14 weeks, including portal connectors and migrating your existing database, with a gradual go-live.
