The verdict in three sentences
A custom notary office management platform costs between 30,000 and 65,000 EUR in Montreal in 2026, with a 4-to-7-month timeline. It digitises deed tracking, scheduling, notarial accounting and the digital vault, with e-filing integration and qualified electronic signature. Custom is justified for offices that want to move beyond the limits of imposed notarial software suites.
What digitising an office costs in 2026
A 6-person notary office compares a standard notarial suite against a custom build. Here are the 2026 orders of magnitude.
| Line item | Notarial suite (buy) | Custom (build) |
|---|---|---|
| Upfront cost | 0 EUR (5,000 EUR setup) | 30,000 - 65,000 EUR |
| Subscription per month | 800 - 2,000 EUR | 0 EUR |
| Annual cost | 9,600 - 24,000 EUR | 0 EUR |
| Maintenance / hosting yr | included | 4,500 - 8,500 EUR |
| Specific modules | limited | included |
| 5-year cumulative | 53,000 - 125,000 EUR | 52,500 - 107,500 EUR |
Over five years custom matches or beats the suite once the office wants specific functions or independence from the vendor.
Deeds, e-filing and the digital vault
Notarial practice imposes strong technical and legal requirements. Here are the key modules and their weight in the build budget.
| Module | Key function | Share of build budget |
|---|---|---|
| Deed tracking | Status, parties, formalities | 20 % |
| Scheduling / files | Appointments and deadlines | 14 % |
| Notarial accounting | Client accounts, escrow | 18 % |
| Digital vault | Legally-valid archiving | 16 % |
| Qualified e-signature | Remote qualified signing | 17 % |
| E-filing | Paperless submission | 15 % |
