The verdict in three sentences
Block management software must cover three non-negotiable obligations: running general meetings, service-charge calls and a secure owners' extranet. In 2026 for an Amsterdam firm, a compliant custom build delivered with a nearshore team costs EUR 45,000 to 110,000, shipped in 16 to 24 weeks. Custom makes sense when market suites impose their processes and per-unit billing, whereas a firm managing several thousand units has specific apportionment and reporting rules.
Regulatory modules and 2026 prices
The scope of syndic software is structured by regulation as much as by the trade. Here are the 2026 ballpark figures for an Amsterdam firm.
| Module | Indicative 2026 price (EUR) | Timeline |
|---|---|---|
| General meeting management | 12,000 to 24,000 | 4 to 6 weeks |
| Service-charge calls and apportionment | 14,000 to 28,000 | 5 to 7 weeks |
| Owners' extranet | 10,000 to 22,000 | 4 to 5 weeks |
| Works and supplier tracking | 8,000 to 18,000 | 3 to 5 weeks |
| Block accounting | 12,000 to 26,000 | 4 to 6 weeks |
| GDPR compliance and audit logging | 5,000 to 12,000 | 2 to 3 weeks |
A meetings-charges-extranet core sits around EUR 40,000 to 70,000. Block accounting and works tracking push the project towards the top of the range.
Custom vs market suites
Comparing a build to a packaged syndic suite means reasoning over five years and over the number of units managed, since most suites bill per unit or per owner.
| Criterion | Packaged syndic suite | Custom software |
|---|---|---|
| Upfront cost | EUR 0 to 4,000 | EUR 45,000 to 110,000 |
| Recurring cost | Per unit or per block | Hosting + 15-18% maintenance |
| Owners' extranet | Included, standardised | Custom, on-brand |
| Apportionment rules | Standard | Fully configurable |
| GDPR compliance | Managed by vendor | Controlled in-house |
| Data exit cost | EUR 1,000 to 5,000 | Nil |
| Time to launch | 2 to 6 weeks | 16 to 24 weeks |
Custom becomes relevant for a firm managing several thousand units, where a suite's per-unit billing quickly exceeds the amortised cost of proprietary software.
Mini case study
Mr Fabre, director of a block management firm in Amsterdam, administers 2,800 units across 90 blocks. A packaged suite at EUR 1.20 per unit per month is EUR 40,320 a year, or EUR 201,600 over five years. Custom software at EUR 78,000 plus 16% maintenance (EUR 12,480 a year) comes to EUR 140,400 over five years. The saving exceeds EUR 61,000 over five years, and the firm gets an on-brand owners' extranet, bespoke apportionment rules and full ownership of its database — with no data exit cost.
