Tell us what you're up to.
A project to launch, an audit to conduct, or an environment that no one understands anymore. From analysis to Level 3 support—you’ll receive a response within 24 business hours.

The form adapts to your request: you only need to fill in the relevant fields.
On-site here, remotely anywhere.
We have three offices in French-speaking Switzerland for anything that requires an on-site presence— Vaud, Valais, Fribourg. For everything else, distance doesn’t matter: from our Swiss offices, we manage portfolios of several hundred sites, no matter where they’re located.
Design, migration, operations, and Level 2 and 3 support: we provide these services from Switzerland, without needing to be in the same country as your users. Travel is only necessary when a physical intervention is required—in which case, it is coordinated with your local teams or our partners.
The questions we're asked most often.
How does the process of requesting a quote work?
We work with you to define the scope of the project, then we provide a detailed proposal that includes costs, a timeline, and deliverables. Preparing the proposal is free of charge. Design studies and audits are included in the scope of work.
Do you get involved after the system goes live?
Yes, and that’s often what brings us to a client. We provide Level 3 support in our areas of expertise and Level 2 support for certain technologies. Taking over an environment that no one else knows how to manage is part of our routine assignments.
What if my publisher isn't on your list?
Ask anyway. We’re certified by Microsoft, Dell, Veeam, Ribbon Communications, 3CX, Luware, AudioCodes , and others—the list shown is never complete, and an enterprise environment rarely relies on a single vendor. Neither do our projects.
How long does it take for you to respond?
Within 24 business hours. For operational emergencies, calling is still the fastest option: +41 21 806 37 15.
Do you charge a flat fee or by the hour?
Both. We offer fixed-price contracts for projects with a defined scope and time-and-materials contracts to reinforce an existing team. Lambert Consulting has been authorized LSE since 2018.
Do you work with small and medium-sized businesses?
Yes. Our projects range from about ten positions to several thousand users, in both the private and public sectors.
What's the status of my request?
It is sent to the sales team’s inbox at Renens and nowhere else. No data is sold, and you will not be automatically subscribed to a mailing list.
