FAQ
Do I need to pay for monthly servers or database hosting?
No for the web portal and database—by building your custom interface on Google AppScript and using Google Sheets as the backend, that infrastructure runs entirely on Google’s free cloud system with zero server fees. However, if your project includes the n8n AI agent, a minor monthly maintenance/host
Is Google Sheets secure enough to use as a database for my business?
Yes, when configured properly. We enforce strict role-based permission controls using Google Workspace security protocols. Users only see or edit the specific data they are authorized to access through the web portal interface, keeping your master sheet protected.
How does the n8n AI agent interact with my company's data?
The n8n AI agent acts as a smart bridge between your database and your communication channels (like WhatsApp, Slack, or web chat). It uses secure API webhooks to read and update your Google Sheets data in real time, answering user queries or executing automated tasks conversationally.
What languages do you offer services in?
I offer full project development, communication, and system localization in four languages: English, Spanish, French, and Portuguese. Whether you need the user interface, documentation, or AI agent responses configured in any of these languages, I’ve got you covered.
