The verdict in three sentences
For a Miami short-term rental manager with 140 units handling 9,000 nights a month, custom software costs between 40,000 and 70,000 USD, delivered in 4 months, against roughly 16 USD per unit per month in SaaS, or about 27,000 USD a year before add-ons. Custom makes sense when three tasks eat the team's time: housekeeping scheduling, monthly owner statements and tourist development and sales taxes, which Miami-Dade and Florida audit closely. The channel manager stays: the tool connects to it rather than replacing it.
Concierge SaaS or custom tool
Short-term rental management SaaS is quick to deploy. It shows its limits when the manager has mixed owner contracts (18 to 25% commission, cleaning recharged or not, linen included or not) and an in-house cleaning team of several dozen people.
| Criterion | Concierge SaaS | Custom tool |
|---|---|---|
| Upfront cost | 0 to 2,500 USD | 40,000 to 70,000 USD |
| Annual cost (140 units) | about 27,000 USD, plus add-ons | 5,000 to 9,000 USD (hosting, maintenance) |
| Channel manager connection | native for some channels | existing channel manager API |
| Housekeeping scheduling | basic, per unit | optimised routes, overlapping check-ins and check-outs |
| Owner statements | standard template | commission rules per contract, automatic monthly PDF |
| Tourist and sales taxes | simple calculation | county tourist tax plus state sales tax, filing-ready export |
| Set-up time | 2 to 4 weeks | about 4 months |
Over three years, the SaaS comes to about 81,000 USD, against 55,000 to 97,000 USD for the custom tool including maintenance. 2026 order of magnitude, sensitive to portfolio growth: at 250 units the gap widens sharply.
Priority features and their budget
Here is a realistic breakdown by package.
| Package | Content | Estimated budget |
|---|---|---|
| Units and owners core | records, contracts, management agreements, documents | 7,000 to 12,000 USD |
| Channel manager connector | bookings, cancellations, net amounts per channel | 5,000 to 10,000 USD |
| Housekeeping scheduling | routes, mobile app for cleaners, end-of-clean photos | 9,000 to 16,000 USD |
| Owner statements | commission, fees, cleaning, payouts, monthly PDF | 8,000 to 14,000 USD |
| Tourist and sales taxes | rates, nights, platform-collected vs direct, filing export | 4,000 to 8,000 USD |
| Dashboard | occupancy, revenue per unit, disputes | 7,000 to 10,000 USD |
In Miami, short-term rental rules are strict: county and state registration, condo association restrictions, zoning limits in some neighbourhoods. A tool that tracks registration status and nights per unit helps avoid fines that can reach several thousand dollars.
Mini case study
Daniel, founder of a 140-unit property management firm in Miami, spends 3 days with two people at the start of each month producing owner statements, or 48 hours. Housekeeping scheduling takes a coordinator 25 hours a week. With the tool, statements drop to 4 hours of checking and scheduling to 10 hours a week. The gain is about 110 hours a month, or 3,300 USD at an internal cost of 30 USD per hour, plus 27,000 USD of avoided subscription. For a 60,000 USD project, payback comes in about 10 months.
