If the internet goes down, your counter keeps selling
In the cloud from anywhere, with a desktop app that invoices offline and syncs everything later.
No more stalled lines
The app keeps invoicing without a connection (CAEA) and syncs on its own.
What you can do
- Desktop app with multiple terminals, synced with the cloud.
- Offline invoicing with CAEA.
- Cash register opening, closing and control; scale support.
Experience in your industry, and in adapting
We work with opticians, real estate agencies, travel agencies, distributors, retailers and shop counters. We’re based in Rosario, we build the software ourselves and we shape it around how you work: if something’s missing, we build it.
AI that saves you hours
Load products without typing: AI writes your descriptions, creates and enhances your product images, and pulls products from your suppliers’ websites with prices, stock and photos. Your customers get an assistant on your store and on WhatsApp, and you get reports just by asking a question.
We work with Google Gemini, OpenAI, Claude and more.
Everything your business needs, in one place

In the cloud, so you can use it from your computer, tablet or phone, plus a desktop app that keeps invoicing even when the internet goes down. Connected to MercadoLibre, MercadoPago and WhatsApp.
