The verdict in three sentences
To digitise your general meetings, charge calls and owner portal, a syndic has two paths: an off-the-shelf solution at 2-6 EUR/lot/month, standardised, or a custom platform at 40,000-90,000 EUR that integrates AGM e-voting, a compliant owner extranet and your own processes. Custom is justified from several thousand managed lots and a need to differentiate from competing syndics. Budget 5 to 9 months of development, with ROI driven by 35% less management time and markedly improved owner satisfaction.
Custom vs off-the-shelf: the 2026 comparison
Off-the-shelf tools bill per lot: at 4 EUR/lot/month for 3,000 lots, that's 144,000 EUR/year. Custom, with a fixed upfront investment, quickly becomes cheaper for a syndic managing a large portfolio, while giving a proprietary asset.
| Criterion | Off-the-shelf | Custom platform |
|---|---|---|
| Entry cost | 0-5,000 EUR (setup) | 40,000-90,000 EUR |
| Recurring cost | 2-6 EUR/lot/month | 10-15% of build/year |
| 3-year cost (3,000 lots) | 216,000-648,000 EUR | 55,000-125,000 EUR |
| AGM e-voting | Vendor-dependent | Custom, integrated |
| Owner extranet | Standard | Branded, complete |
| Process fit | Low | Total |
| Time to launch | 3-8 weeks | 5-9 months |
For a large portfolio, per-lot billing quickly becomes prohibitive: beyond 2,000-3,000 lots, custom is often cheaper from year one or two, while removing vendor lock-in.
Compliance and modules of a syndic platform
Regulation makes the owner extranet mandatory: co-ownership documents available online, minutes, contracts, budgets. A serious platform goes further with dematerialised AGMs and e-voting.
| Module | Contents | Budget weight | Priority |
|---|---|---|---|
| Owner extranet | Documents, minutes, contracts | 7,000-13,000 EUR | High |
| Online AGM & e-voting | Convocations, electronic voting, quorum | 10,000-18,000 EUR | High |
| Charge calls | Schedules, reminders, collections | 8,000-15,000 EUR | High |
| Co-ownership accounting | Charge allocation, forecast budget | 8,000-14,000 EUR | High |
| Works & quotes | Works tracking, competitive bidding | 5,000-10,000 EUR | Medium |
| Tickets & incidents | Owner reports, follow-up | 4,000-8,000 EUR | Medium |
| Manager dashboard | Portfolio, alerts, KPIs | 4,000-8,000 EUR | Medium |
Online AGM with e-voting is the differentiating module: it sharply reduces meeting logistics (mailings, physical attendance, vote counting) and improves owner participation.
Mini case study
Ms Laurent, who runs a syndic firm in Lyon managing 2,800 lots across 55 co-ownerships, employs 6 managers. Each spends ~10 hours/week on digitisable admin tasks (sending documents, answering owners, preparing AGMs), or 60 hours/week for the team. At 40 EUR/hour loaded, that's ~2,400 EUR/week, or 124,800 EUR/year.
A custom platform at 78,000 EUR cuts that time by 35%, or ~43,700 EUR/year recovered. Adding savings on AGM logistics (postal mailings, venues, vote counting, ~9,000 EUR/year), the gain exceeds 52,000 EUR/year. The tool is paid back in under 18 months, then generates net annual margin while building co-ownership loyalty.

FAQ
How much does property management software for syndics cost in 2026?
Between 40,000 and 90,000 EUR custom, versus 2 to 6 EUR/lot/month off the shelf. Beyond 2,000-3,000 lots, custom often becomes more economical.
Is the owner extranet mandatory?
Yes: regulation requires an extranet giving access to co-ownership documents (minutes, contracts, budgets). A custom platform lets you offer it branded and go further.
Is AGM e-voting legally reliable?
Yes, provided convocation, quorum and vote-traceability rules are respected. A well-designed e-voting module time-stamps and secures each vote to guarantee the meeting's validity.
What time savings can I expect?
On average 35% less administrative management time (documents, responses, AGM preparation), plus savings on meeting logistics. For a firm managing several thousand lots, that means tens of thousands of euros per year.
How long to build the platform?
Expect 5 to 9 months. A first release (extranet + charge calls + accounting) ships in ~5 months, with online AGMs and e-voting reinforcing the whole afterwards.
