The verdict in three sentences
For a Montréal property manager with 80 short-term rental units, off-the-shelf software at 15 to 35 CAD per unit per month (2026 market ballpark) costs 14,400 to 33,600 CAD a year, while a fully custom platform at 40,000 to 85,000 CAD only makes sense when your operations clearly outgrow the standard. The best value in 2026 is a hybrid: keep a proven channel manager to sync Airbnb and Booking.com, and build a custom back office for registration checks, cleaning crews and owner payouts. That is where most managers lose 10 to 12 hours a week to spreadsheets.
What Québec rules mean for your software
In Québec, every short-term rental listing must display a valid registration number issued under the province's tourist accommodation rules (the CITQ registration), and platforms are required to check it. Montréal has added its own bylaws restricting where and when principal residences may be rented, and boroughs apply zoning rules on top: check the current city bylaw and your borough before configuring anything. For a manager handling dozens of owners, that means tracking each unit's registration status, its type (principal residence or not) and its allowed rental periods, then blocking calendars automatically.
Taxes add work: the lodging tax and sales taxes must be handled correctly whether the platform collects them or you do, and owners expect clear annual statements.
| Need | Off-the-shelf PMS and channel manager | Custom back office | Indicative custom budget (2026 market ballpark) |
|---|---|---|---|
| Airbnb, Booking.com, Vrbo sync | Excellent | Not worth rebuilding | 0 CAD (keep the tool) |
| Registration and permitted periods | Displays the number | Tracks status, expiry and allowed dates per unit | 6,000 to 12,000 CAD |
| Cleaning and linen scheduling | Basic | Optimised routes, photo checks | 8,000 to 16,000 CAD |
| Owner payouts | Export to rework | Net calculation, PDF statement, batch transfer file | 10,000 to 20,000 CAD |
| Owner portal | Varies by vendor | Revenue, bookings, documents | 8,000 to 16,000 CAD |
| Lodging and sales tax reports | Partial | Consolidated by unit and month | 5,000 to 10,000 CAD |
A fully custom platform including channel sync sits between 40,000 and 85,000 CAD. A back office alone, connected to your channel manager by API, usually lands between 20,000 and 40,000 CAD.
Three-year cost by option
Well-known tools such as Guesty, Hostaway or Lodgify charge a monthly fee per unit, with public prices that vary by plan and add-ons.

|---|---|---|---|
| Subscriptions | 43,200 to 100,800 CAD | 43,200 to 100,800 CAD | 0 CAD |
| Development | 0 CAD | 20,000 to 40,000 CAD | 40,000 to 85,000 CAD |
| Hosting and maintenance | Included | 3,000 to 8,000 CAD | 8,000 to 15,000 CAD |
| Weekly admin time | 14 h | 3 h | 3 h |

Mini case study
Illustrative example: Marc-André, owner of a Montréal property management company, runs 80 units, 30 of them principal residences, with three office staff and contracted cleaning crews.
- Admin time: 14 h a week today (owner statements, cleaning schedules, registration checks) versus 3 h with the back office. Saving: 11 h × 48 weeks = 528 hours a year, or 21,120 CAD at a 40 CAD loaded hourly cost.
- Payout disputes: 2 or 3 a month, brought close to zero, which keeps owners from moving to a competitor.
- Investment: a custom back office at about 15,000 CAD, plus around 2,000 CAD a year in maintenance.

FAQ
Should we replace our channel manager with custom software?
Rarely, as rebuilding Airbnb and Booking.com sync is expensive and adds little. Keeping your tool and adding a back office by API roughly halves the budget, often 20,000 to 40,000 CAD on the market.
How does the software enforce permitted rental periods?
It stores each unit's registration and type, applies the dates your borough allows, and blocks the calendar outside them across every channel. When the bylaw changes, you update one setting instead of 80 calendars.
How long does a back office take to deliver?
Plan on 6 to 10 weeks depending on modules. Start in the autumn so the system is live well before the summer season and the festival peak.
Can owners see their revenue online?
Yes, an owner portal shows bookings, revenue, cleaning fees and monthly statements in French or English. It adds 8,000 to 16,000 CAD at market rates and cuts owner calls sharply.
Can the system prepare owner transfers?
It calculates each owner's net after commission and fees, then generates a batch payment file for your bank. For 80 units, payout preparation drops from 2 days to about 1 hour a month.
