The verdict in three sentences
A property manager in Toronto handling 400 to 2,000 units needs to automate rent receipts, charge calls and owner accounts. A SaaS at 5-15 EUR/unit/month is the natural starting point; a custom build at 30,000-65,000 EUR is justified beyond 1,500 units or for a differentiating owner/tenant portal. The target gain is concrete: -1 admin FTE and a much faster accounting close.
What digitised property management costs in 2026
Editors bill per managed unit. Custom usually includes the dual portal. 2026 orders of magnitude for a firm managing 800 to 1,500 units.
| Criterion | Per-unit SaaS | Custom build |
|---|---|---|
| Unit cost | 5-15 EUR/unit/month | 30,000-65,000 EUR |
| Year 1 cost (1,000 units) | 60,000-180,000 EUR | 35,000-72,000 EUR |
| Year 3 cumulative | 180,000-540,000 EUR | 45,000-90,000 EUR |
| Owner/tenant portal | Standard | Bespoke |
| Charge calls | Automated | Automated + own rules |
| Time to launch | 3-6 weeks | 4-7 months |
| Integrated accounting | Per module | Bespoke |
Beware the per-unit pricing trap: beyond 1,000-1,500 units, per-unit SaaS can exceed a custom build amortised from year 2. Below 500 units, SaaS is unbeatable.
What automation recovers
Property management concentrates high-volume repetitive tasks. Automating them frees admin time and makes accounting more reliable.
| Task | Manual | Automated | Gain |
|---|---|---|---|
| Rent receipts (1,000 units) | 3-4 days/month | Automatic | ~partial FTE |
| Annual charge calls | 5-8 days | 1-2 days | -75 % |
| Charge reconciliation | 6-10 days | 2-3 days | -65 % |
| Arrears follow-up | Manual | Scheduled | -30 % arrears |
| Accounting close | 10-15 days | 4-6 days | -50 % |
For a 1,200-unit firm, saving nearly one admin FTE (35,000-42,000 EUR loaded/year) alone covers a custom build in under 2 years.

Per-unit billing is attractive at launch but becomes a growth trap. At 5 EUR/unit/month, managing 300 units costs 18,000 EUR/year — perfectly reasonable. But at 12 EUR/unit/month across 1,500 units, the bill climbs to 216,000 EUR/year, an amount that funds a full custom build every year. The financial tipping point generally sits between 1,000 and 1,500 managed units: beyond that, a management firm has a direct economic interest in bringing its tool in-house, especially since code ownership lets it adjust its charge rules, allocation grids and regulatory documents without depending on an editor's roadmap. A second, often overlooked argument: compliance. Local regulations impose precise wording on receipts, charge statements and reconciliations; a custom build guarantees immediate adaptation to legal changes, where a SaaS imposes the editor's update pace. Finally, the owner/tenant portal has become in 2026 a mandate-retention criterion: landlords compare firms on the transparency offered. A firm offering real-time tracking of collections, documents and intervention tickets cuts its mandate loss rate by several points a year.
Mini case study
Sophie runs a property management firm in Toronto: 1,100 units managed, 3.5 admin FTEs. Receipts, charge calls and reconciliations consume the equivalent of 0.9 FTE, or ~34,000 EUR loaded/year. On SaaS at 12 EUR/unit/month she would pay 158,400 EUR/year — unsustainable at this scale. A 58,000 EUR custom build with owner/tenant portal, amortised over 3 years (~19,300 EUR/year including maintenance) plus the recovered FTE, generates a net saving of ~15,000 EUR from year 2 and halves the accounting close.
FAQ
Is per-unit SaaS always cheapest? No. Below 500 units, yes; beyond 1,000-1,500 units, SaaS at 10-15 EUR/unit/month can cost more than a custom build amortised over 3 years.
What does the owner/tenant portal cost? Budget 8,000-18,000 EUR custom for a dual portal (documents, receipts, charge calls, tickets), highly valued by landlords.
How long for a custom build? Between 4 and 7 months for receipts + charges + accounts + portal, with an accounting V1 in 12-14 weeks.
What gain on arrears? Automated follow-ups cut arrears by an average of 25-30 % and secure landlords' cash flow.
Can accounting and tax export be integrated? Yes: compliant integrated accounting (ledger, journals, export) avoids 8-12 days of re-entry per year and makes the close reliable.
