The verdict in three sentences
A custom HOA/syndic tool digitizes general-meeting e-voting, per-building accounting and communication via an owner extranet. Budget 40,000 to 95,000 EUR with delivery in 18 to 24 weeks, ELAN-law compliant, and maintenance at around 15%/year. Target: -30% admin time per managed condominium.
Regulatory and operational modules
Syndic management combines legal obligations (e-voting, mandatory extranet) with accounting efficiency. 2026 order of magnitude.
| Module | Dev time | EUR range | Gain / compliance |
|---|---|---|---|
| E-voting in GM | 4-5 wks | 11,000-19,000 | Compliance + auto minutes |
| Owner extranet | 4 wks | 10,000-16,000 | ELAN-law obligation |
| Per-building accounting | 5-6 wks | 13,000-22,000 | Exact charge allocation |
| Fund calls & follow-ups | 3-4 wks | 8,000-14,000 | Arrears -20% |
| Works & quote management | 3 wks | 7,000-12,000 | Works-vote tracking |
A "GM + extranet + accounting" core starts around 40,000 EUR; the full scope with works management approaches 95,000 EUR.
Real cost vs. the market
Syndic software often bills per unit or per managed condominium. 2026 comparison for a firm managing 45 condominiums (~1,800 units).
| Option | Upfront cost | Annual recurring | 3-year cost |
|---|---|---|---|
| Market software (per unit) | 4,000 EUR | 21,600 EUR | ~68,800 EUR |
| Premium market software | 8,000 EUR | 36,000 EUR | ~116,000 EUR |
| Custom Essential | 40,000 EUR | 6,000 EUR (maint.) | ~58,000 EUR |
| Custom Extended | 80,000 EUR | 12,000 EUR (maint.) | ~116,000 EUR |
Beyond 1,500 units, per-unit market billing meets then exceeds custom, without flexibility on your charts of accounts.

Mini case study
Marc, who runs a syndic firm in Lille, manages 45 condominiums with 5 managers. GM preparation and accounting entry push the team to saturation in peak season. He invests 80,000 EUR in a custom tool (e-voting + extranet + accounting + fund calls) plus 12,000 EUR/year in maintenance. Cutting admin time by 30% frees ~1.5 FTE (~60,000 EUR/year), letting him manage 8 extra condominiums without hiring — at average fees of 12,000 EUR/condominium/year, that's 96,000 EUR of potential additional revenue: the tool pays back within the first full year.
