Our tools:

Integrated management software

Our management software is developed in-house by our IT department, and is continually updated in line with new developments in our business.

This in-house software development gives us a level of responsiveness and flexibility that is unique in the real estate sector, and also promotes precision and security in the processing of data relating to managed property.

By doing this, Brolliet has been a pioneer in the digitisation of all the standard documents.


An online system for accessing secure data, accessible 24 hours a day, free of charge to our clients.

Brolliet offers all of its property owners an online system for accessing secure data, available 24 hours a day via our e-brolliet service. An online demonstration is available and can be used to train new users.

  • The following information is also available at any time:


Technical Tablets

TechNo, a tool used by our technical managers, enables instant electronic creation of inspection reports.


Electronic data (CD Rom, USB key, Brolliet online)

  • Intuitive data presentation and navigation
  • Visualisation of all accounts, their related invoices and estimates, and any entries generated at month end, without the need to install additional software.


Electronic document management (EDM) and the management process:

Records for each building, respectively for the associated units, can thus be precisely logged and reported.

As digitisation is carried out as soon as each document arrives, they are processed and tracked electronically, thus maximising the efficiency of the processes as well as enhancing traceability and checks.
