Our Company


Managing income property presents challenges that Stevens Coulombe knows well.

An experienced rental property owner with a solid background in software development Stevens founded Alliance Web-Commerce in 1997 and two years later in 1999, launched the sideManager.com site to provide online services.
Since then, Alliance Web-Commerce has served respected organizations such as the Société Immobilière Trans-Québec (SITQ), Hydro-Québec, L'École de Technologie Supérieure and Télé-Québec to name a few.
The Company was one of the first in Canada to carry out Internet transactions in compliance with the highest banking security standards.

Needing an efficient, easy-to-use property management tool, Stevens combined his experience in property management and in product and services development to create a powerful, flexible and simple online property management tool. In late 2005, Alliance Web-Commerce introduced a module for producing Relevé 4s that was certified by the Ministère du Revenu du Québec. And now, you get all the advantages of his property management expertise with the new sideManager.com assistant!

Whether you own one income property or many, sideManager.com gives you true value.
