Companies without an ERP system often use different software packages that either don’t communicate with each other, or do so poorly, and have to be maintained individually.
An ERP system enables you to centralize information, instantly interconnect the company’s various functions, better control costs and improve data security.

A business ERP (Enterprise Resource Planning) or business software is an integrated management software package that meets the specific needs of a company in a target sector of activity; whereas a general ERP requires a lot of parameterization and specific developments to meet a business need. Business ERP is the specialized version of a general-purpose ERP.

SaaS stands for Software As A Service. This software consumption mode allows you to work from any device connected to the Internet via a Web browser. We manage your servers, databases, application (code, maintenance, etc.), security and support.

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

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 🙂

vsa is a business ERP that enables you to manage your foreign subsidiaries: multi-company, multi-tax and multi-currency. The interface offers full navigation in English or French. Documents (quotes, contracts, timesheets, invoices, etc.) can be edited in the language of your choice.

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.

If you have requested a trial or demo, you are normally already in contact with our sales team. If not, you can contact them using the contact form.

The data you integrate and manipulate through our SaaS applications, and which is therefore located on our servers, is the property of your company.

It’s our job to host the data used in our applications. That’s why we invest heavily in security, backup management and maintenance – far more than any normal company would.
To underpin our commitment in this area, we have been ISO27001 certified since 2022.

Your data is 100% hosted in France, and redundant in different datacenters. Since 2012, we’ve been working with Scaleway, a major player in the hosting market.

vsa is not concerned by this certification. vsa is dedicated to B2B activities: an invoice is therefore issued to the customer (company) before being able to record whether or not it has been paid.
Article 286-l-3 bis of the General Tax Code expressly states that this obligation only applies to sales to private individuals (not subject to VAT).

vsa is already managing a very large proportion of what will be required by the reform to introduce generalized electronic invoicing.

You must be logged in to the software or mobile application to make your request to our Support team. A ticket number will be assigned for fast, efficient follow-up.

The arrival of vsa in your company is a bit like the arrival of the Internet in the 2000s: we wonder how we did it before!
