A family business from San Martín, Mendoza
Sergio Martinez founded KeySistemas in 1995. Today the three of us run it: Sergio, Tomás and Gonzalo.
Our history
The first jobs were invoicing systems written in DOS for local shops. KeyGestión appeared with Windows. It has been rewritten several times since then and is still the core system.
Along the way came the corralito, several economic crises, four generations of Windows and a tax regime that changes every year. The company kept running from the same place.
Tomás and Gonzalo joined later. Since 2020 five new systems have come out: orders, online store, medical gas, packing and transport. Each one was asked for by a client who needed something that did not exist.

How we work
An implementation goes through these three stages.
We survey
We go to your company and look at how you work today: invoicing, stock, purchasing.
We adapt and install
We adjust the system to your workflow, install it on your server and migrate your data.
We provide support
After go-live we keep answering by phone and WhatsApp.
Frequently asked questions
Will you still be around in ten years?
The company has been running since 1995. It belongs to the family and the second generation already works in it every day.
Three people. Is that not too few?
There are three of us. Whoever wrote your module is the one who answers, and all three of us know every installation.
Where are you?
In San Martín, Mendoza. We work with companies across the province and the rest of the country. If you are nearby, we come to see you.
If something breaks on a Tuesday afternoon, what do I do?
You call or send a WhatsApp and someone who knows your installation answers. If we need to get into the server, we do.
