QUESTIONS BEFORE STARTING
Clear answers without opening WhatsApp.
The important details you should know before trusting us with your operation.
01How long does it take to move my data?+
It depends on the amount and quality of your current information. We review it first and agree on a migration plan before making changes.
02What happens to my data if I cancel?+
We coordinate the export of your information and account closure. Plans have no minimum term.
03Do I need internet all the time?+
Zentra and ZentraCare run in the cloud, so an internet connection is required to use them and keep information synchronized.
04Will my team learn it quickly?+
Training and guided setup are included. We configure the initial workflow around the way your team actually works.

The platforms operate in the cloud and include backups for operational continuity. Access and handling are reviewed during implementation.
