The verdict in three sentences
Custom real estate agency software costs between 35,000 and 95,000 EUR in 2026, depending on whether you stop at the mandates + CRM core or add multi-portal syndication, e-signature and a mobile agent app. The real ROI comes not from the software itself but from automated supply/demand matching, which turns dormant listings into closed sales. Plan a 10 to 18 week project and a managed-hosting subscription of 400 to 1,200 EUR/month.
What each module costs in 2026
The price of real estate software is read brick by brick. An off-the-shelf SaaS costs 60 to 200 EUR/month per user but locks you into its model; custom is justified as soon as your process breaks the standard (network of agents, property dealer, atypical rental management).
| Module | What it does | 2026 range (EUR) | Timeline |
|---|---|---|---|
| Mandates + listings core | Property records, mandates, statuses, history | 11,000 – 20,000 | 3–4 wks |
| Buyer CRM + matching | Contacts, criteria, auto-matching | 8,000 – 18,000 | 3–4 wks |
| Multi-portal syndication | Portals, XML feeds, one-click publish | 7,000 – 15,000 | 2–3 wks |
| E-signature | Mandates and sale agreements signed remotely | 5,000 – 10,000 | 1–2 wks |
| Mobile agent app | Viewings, photos, on-site mandate capture | 9,000 – 22,000 | 3–5 wks |
| Seller/buyer portal | Deal tracking, documents, alerts | 5,000 – 12,000 | 2–3 wks |
A 5-to-8 negotiator agency usually targets core + CRM + syndication, i.e. 35,000 to 55,000 EUR. Networks wanting the agent app and e-signature reach 70,000 – 95,000 EUR.
The real gain: supply/demand matching
The value core of real estate software is matching: as soon as a mandate is entered, the system crosses its criteria with the buyer base and alerts both the agent and the client. This shortens time-to-sale and reduces listings rotting in the portfolio.
| Metric | Without auto-matching | With auto-matching | Effect |
|---|---|---|---|
| Average time-to-sale | 95 days | 68 days | −28% |
| Listings shown to the right buyer in 24h | 15% | 70% | ×4.6 |
| Data entry/syndication per listing | 40 min | 8 min | −80% |
| Mandate → sale conversion | 42% | 55% | +13 pts |
| Portal re-entry | Manual | None (feed) | 0 errors |
Mini case study
Marc, director of a 6-negotiator agency in Bordeaux, manages 180 active mandates. Previously each listing was re-typed by hand on 3 portals (40 min) and matching was done "from memory". He invests 34,000 EUR in a mandates + CRM + syndication core, delivered in 12 weeks. Over 12 months: time-to-sale drops from 95 to 70 days, and 9 extra sales close thanks to matching alerts. At an average 7,000 EUR commission, that is 63,000 EUR of additional fees — the tool pays back in under 8 months, before the data-entry time saved (about 4 hrs/week per negotiator).

Build from scratch or adapt an existing SaaS?
If your process is standard, an 80–150 EUR/month/user SaaS is enough. Custom (35,000 EUR+) is justified when you have an atypical model (agent network, rental management, property dealing) or want to own your data and feeds.
Is multi-portal syndication truly automatic?
Yes: publishing goes through standardized XML feeds. A listing entered once goes to all portals with no re-entry. Budget 7,000 to 15,000 EUR for this module and 2 to 3 weeks.
Is e-signature legal for a sale agreement?
Yes, a qualified electronic signature (eIDAS) carries the same value as a handwritten one. The module costs 5,000 to 10,000 EUR to integrate, plus a per-signature provider fee (0.50 to 2 EUR).
How much is annual maintenance?
Plan 15 to 20% of the build cost per year, i.e. 400 to 1,200 EUR/month for hosting, portal-feed updates and support.
Can we start small then extend?
Yes, and it is recommended: deliver the mandates + CRM core first (35,000 EUR), measure the gain, then add the agent app and client portal in phase 2.
