The workflow
Cosmantar follows the work the way your business actually runs — so nothing gets lost between the phone, the spreadsheet and the invoice.
Step 1 · Inquiry
A new call from (512) 555-0148 is matched to an existing client automatically. The full history — past jobs, invoices and messages — is one click away.
Useful power
Each tool is built around one clear task. You see what runs, when it runs and what it costs before anything happens.
Assign recurring work like payment follow-ups, appointment reminders or lead qualification. Agents run on the schedule you approve and report every action.
