Custom customer portal for an elevator maintenance company in New York: 2026 cost

The verdict in three sentences

An elevator contractor maintaining more than 1,000 units loses hundreds of hours a year on the phone answering one question from property managers and landlords: "what is the status of the breakdown?". A custom customer portal connected to your maintenance management system (CMMS) costs between 35,000 and 70,000 EUR excl. VAT in 2026 (roughly 38,000 to 76,000 USD) and targets 40 % fewer inbound calls. The decisive item is not the interface but the quality of the CMMS API: without reliable real-time data, the portal is useless.

Why property managers demand a portal in 2026

Regulations require frequent maintenance visits, periodic inspections and an up-to-date logbook: in France a visit every 6 weeks and a five-yearly inspection, in New York annual and five-year inspections filed with the Department of Buildings. Property managers and housing providers, sometimes running 200 buildings, want access to these documents without calling. At contract renewal they now compare elevator contractors on their digital tools, alongside uptime and response time.

A useful portal shows, for each unit: real-time status (in service, out of order, intervention in progress), breakdown history, signed visit reports, inspections and cleared defects, pending quotes and invoices. Email or SMS notifications at every status change remove most follow-up calls.

2026 budget by module

A minimal scope (core, breakdown tracking, documents, API) starts around 35,000 EUR. The top of the range matches a legacy CMMS without a documented API, which requires building an exchange layer via files or a staging database.

Timeline, operations and return on investment

The project runs over 4 to 6 months: 3 weeks of scoping with operations teams and 2 or 3 pilot property managers, 10 to 14 weeks of development in sprints, a 4-week pilot on 300 units, then gradual rollout. Hosting must comply with data protection rules for occupant data (GDPR in Europe, state privacy laws in New York).

Mini case study

Laurent, operations director at an elevator contractor (2,300 units, 45 technicians), commits to a portal at 52,000 EUR excl. VAT with 11,000 EUR per year of maintenance and support. The switchboard receives 3,200 calls a month. With 40 % fewer calls, he saves 86 hours a month, about half a customer service position at 38,000 EUR fully loaded per year, so 19,000 EUR per year. Add 370 document requests by email avoided per month, about 10 minutes each, or 740 hours a year. The direct gain exceeds 35,000 EUR per year for an annual cost of 11,000 EUR: payback in about 26 months, before counting contracts retained at renewal.

FAQ

Why not use the portal supplied by the CMMS vendor?

One sometimes exists, often billed 2 to 5 EUR per unit per month, but it is rarely customisable and poorly rated by property managers. For 2,300 units, that is 55,000 to 138,000 EUR per year, more than a custom portal over 3 years.

Is real time really possible?

Yes, if the CMMS exposes an API or webhooks: latency is then a few seconds. Otherwise, a sync every 5 minutes is enough for property managers.

Can we integrate remote monitoring of units?

Yes, connected devices report breakdowns automatically. Integration costs an extra 6,000 to 12,000 EUR excl. VAT depending on the manufacturer's protocol.

Who owns the code?

You do. The contract assigns the economic rights and the code is delivered to your repository, so you can switch maintenance providers.

Do we need a mobile app?

Rarely at first. An installable responsive web app covers 90 % of property manager use cases and costs 2 to 3 times less than a native app.
