Immo for integrators

The solution for your clients that work in the real estate industry

What we're being told

"We created a site for a client and we want to synchronize the listings with Centris, but the extensions don't work..."

"We are specialized in UI/UX design, but we are not experts at Website management, and we now realize that it's more complex than we thought..."

"We haven't added the listings to the site yet, and it's already too slow... plus, we think that the development site was hacked... we didn't have time to complete all the updates..."

What we offer

A site to customize in Software-as-a-Service (SAAS) mode for your clients that work in the real estate industry.

We take care of the technical aspects, you take care of the design and content.

The offer includes:

  • Web hosting
  • Connection to a domain name (not included)
  • WordPress site
  • Synchronization with Centris
  • Flexible theme to customize
  • Over 30 real estate functionalities and widgets

How it works


Propulsif offers a 25% discount to integrators on the regular price of the monthly package + additional brokers.

Brokers enrolled with Centris are not eligible to this offer.


Technical Support

The integrator will be responsible for the technical support to their clients using the Immo platform. If they can't resolve a problem, they can ask for the help of Propulsif, who doesn't reply to direct requests made by a reseller's clients.


Resale price

The integrator is free to establish the price he resells access to the Immo platform, and can also combine it in a custom service offer.

Plugin vs. Platform

Many integrators prefer to buy an add-on they can install on their site over monthly fees.

The concepts described offer the flexibility of use, lower costs, and a independence from the plugin developer.

At Propulsif, because of our experience of over 10 years as Web integrators and with Immo since 2014, our opinion somewhat differs...

Plugin Purchase

Platform Subscription

Integration Required

It is normally essential to edit the base design offered by a plugin, in order to harmonize it with the look of your site.

Manual Updates

You are responsible for the plugin updates, its good working order with your theme and all other installed plugins.

Site Maintenance

You must perform all the updates regarding WordPress, your theme, and other plugins installed, to avoid any bad surprises.

Email Issues

On shared hosting services, emails may not be sent, or stopped by antiviruses, and end up in the SPAM folder of your clients.

Limited Options

The functions offered by Centris plugins are generally limited, and the possibility to modify the layout of the listings is very constrained and difficult.

Incomplete Solution

You are responsible to find and integrate the plugins (or to develop them) that include the standard Real Estate tools offered on typical Real Estate sites.

You are responsible for everything

You are responsible to manage the web hosting service, to ensure the emails are sent, to implement a backup strategy, and to conform to all regulations regarding the use of Centris' data.

And in case of technical problems... who you gonna call?


Your site will be ready to use within 24 hours following your approval with Centris, including our turnkey themes and the synchronization of your listings.

Automated Updates

We automatically carry out the plugin updates and the synchronization with Centris, following the development of new functionalities.

Zero Maintenance

The Immo platform always uses the most recent version of WordPress, and we ensure a constant watch on themes, plugins, and the connectivity to Centris.

Guaranteed Delivery

We use the external transmission gateway Sendgrid, for an email transmission rate of 100%. No more lost info or visit requests.

Total Flexibility

Our approach allows us to decide which elements of Centris to display, in what order and where, using visual editors, widgets, as well as a modern theme optimized for mobile devices.

Real Estate Tools

Our solution includes many Real Estate calculators, dynamic forms with notifications, and visit statistics per listing. It's all there.

Turnkey Formula
