The verdict in three sentences
For a Toronto developer wanting to track projects from reservation to closing, custom software costs between 70,000 and 160,000 EUR in 2026, delivered in 5 to 9 months. Vertical off-the-shelf tools cover a standard price grid but stumble on your financing structures, deposit schedules and legal closing flows. The decisive gain is measured on time to market: a few weeks saved per project represent hundreds of thousands in advanced cash flow.
What custom development software covers
The heart of it is the chain reservation -> reservation contract -> financing -> closing, with a living price grid and fine per-project reporting.
| Module | Scope | Indicative 2026 cost (EUR) | Timeline |
|---|---|---|---|
| Price grid & inventory | Units, tax, price changes | 10,000 - 22,000 | 4-6 wk |
| Reservations & options | Contracts, cooling-off, follow-ups | 12,000 - 26,000 | 5-7 wk |
| Buyer financing | Loan tracking, conditions | 9,000 - 20,000 | 4-6 wk |
| Legal & closings | Schedule, deposits, deeds | 11,000 - 24,000 | 4-7 wk |
| Project reporting | Margins, absorption, cash flow | 9,000 - 18,000 | 3-5 wk |
| Core + integrations | Auth, roles, accounting, CRM | 14,000 - 34,000 | 6-9 wk |
Add maintenance of 1,800 to 4,000 EUR/month depending on active projects and expected service level.
Vertical solution or custom: 2026 comparison
Vertical vendors offer a fast start; custom fits your structures and removes the per-user fees that climb with your sales teams.
| Criterion | Vertical solution | Custom by Kolonell |
|---|---|---|
| Year 1 cost | 12,000 - 30,000 EUR/yr | 70,000 - 110,000 EUR |
| Year 5 cumulative | 60,000 - 150,000 EUR | 110,000 - 200,000 EUR |
| Financing structures | Standard | 100% tailored |
| Deposit schedule | Fixed framework | Custom per project |
| Implementation time | 2-4 months | 5-9 months |
| Ownership & flexibility | Limited | Full |
Below 2 simultaneous projects, a vertical solution often suffices. From 3-4 parallel projects and atypical structures, custom becomes profitable over 5 years.

Mini case study
Sophie, project director at a Toronto developer launching 4 projects/year of 40 units on average, finds custom software saves about 4 weeks of sales time thanks to real-time reservation tracking and automated follow-ups. On a project generating 12M EUR in revenue, bringing collections forward by 4 weeks frees cash and avoids financing costs estimated at 35,000 - 55,000 EUR per project. With 4 projects/year, the 120,000 EUR software is amortised in the first year.
