Your business already lives on WhatsApp. Now it has an office there.
Talk to her like an assistant: a voice note as you walk out of each client. Marthina files the client and the sale, writes the quote, reminds you when to call, tells your team, and it's all waiting in your dashboard.

Your team uses the WhatsApp they already have. Nothing to install, nothing to pay. You see every job in real time.
- The client signs on the phone. A PDF report with photos goes to their email.
- Someone's on holiday? “Juan covers for Ana until Monday.” Done.
- Time tracking the law asks for: “in”, “break”, “out” on WhatsApp. Hours, corrections with a reason, and the Excel for your accountant.
- Sales reps see only their clients. The boss sees everything.
- Read-only access for whoever just wants to watch: a partner, a manager.
