What are the advantages of SaaS?

SaaS offers advantages for companies of all sizes: financial savings, scalability, accessibility, updates and maintenance.

How does a VSA project work?

Once you have chosen vsa, a consultant is appointed as your account manager. He or she will contact you to schedule a kick-off meeting for your project. This will enable us to schedule the milestones you have chosen (data transfer, training, configuration, etc.) right up to your start-up.
A vsa project always goes very well 🙂

Am I autonomous in managing my users in VSA?

Yes, you can add users and assign them the right application rights.
vsa is a very complete and powerful software package, but we’ve organized the application to give our customers maximum autonomy in terms of configuration and administration. Of course, our Support and Consulting teams are always on hand to help you.

How is VSA ERP SaaS subscription billed?

Subscription to vsa is billed monthly. This is based on the number of employees belonging to or working for your company (precise prorata temporis) to provide a subscription that is as accurate as possible and that adapts to your company’s development. For companies with up to 100 employees, tiers are proposed; then beyond that, as your workforce grows, the unit rate per employee decreases.

In addition to the standard benefits of SaaS, we include :
– MyVS mobile application
– An API
– Our Fit Your Needs tool, which lets you submit requests for upgrades and monitor the roadmap
– A customer area (information, events, webinars, invoices, etc.)
– Comprehensive documentation
– Free webinars
– Organization of annual meetings between users (Users’ Club)

What is the time commitment?

Our SaaS subscriptions are open-ended. You can cancel with 4 to 7 weeks’ notice, depending on your cancellation date.

What are the payment options?

You can pay for your SaaS subscription by direct debit, credit card or bank transfer.
