Roster | AI-Powered Business Assistant Node.js Script

Most small businesses lose money in the same three places: calls nobody answers, leads nobody follows up, and customers nobody contacts again. Roster is a self-hosted platform that covers all three with an AI agent you configure, on a server you own, using API keys that belong to you.

Nothing is proxied through anyone else. There is no per-seat fee, no monthly platform charge, and no usage passing through a third party. You install it once and it is yours.

What it does
Answers, in writing and out loud. An AI agent handles website chat, SMS, WhatsApp and phone calls. You set its persona, its knowledge, its boundaries, and whether it replies on its own or drafts for a human to approve.
Finds new leads. Search Google Maps by niche and city and get back real local businesses, complete with phone, website, rating and review count, as leads ready to work.
Texts back every missed call. Automatically, within seconds. For a business that misses calls, this single feature usually pays for the item.
Brings customers back. Retention rules for win-back, review requests, birthdays and reactivation, running on a schedule across email, SMS and WhatsApp.
Runs the pipeline. Leads, contacts, a drag-and-drop board with your own stages, and tasks assigned to people with due dates.
Books and reminds. Appointments with real availability, automatic reminders, and optional two-way sync to Google Calendar or Outlook.
Invoices and gets paid. Line items, taxes, recurring invoices, and a payment link through Stripe or Paystack that marks the invoice paid by itself.
Manages reputation. Review requests after completed work, incoming reviews collected and answered, sentiment tracked over time.
One inbox for all of it. Chat, SMS, WhatsApp and email in a single thread per person, whichever way they arrived.
