AI agents for business: hire an AI worker for sales and support
An AI agent for business is AI that does a defined job, such as replying to enquiries, quoting and booking, using your data and rules, and hands over to a person when needed. Nerb calls one in a set role an AI worker.

What is an AI agent, and how is it different from a chatbot?
An AI agent is AI that takes actions towards a goal, not just replies: it understands a request, looks up what it needs, uses your tools and hands over to a person when needed. A chatbot answers questions. An automation follows fixed rules. An AI worker is an AI agent given a whole role, such as sales or customer support.
| Compare | Chatbot | Automation | AI worker (an AI agent in a role) |
|---|---|---|---|
| What it does | Answers questions in a chat window | Runs a fixed sequence when something happens | Performs a defined job role end to end |
| Handles | Common questions | Predictable, repeated steps | Varied requests, in any wording, on any channel |
| Uses your data | An FAQ or knowledge base | The fields it was built around | Linked customer, job, quote and invoice records |
| Takes actions | Rarely | Only the steps it was scripted for | Quotes, bookings, invoices, messages, record updates |
| Example | “We open at 9am.” | “Send a receipt when an invoice is paid.” | “Quote 4 units, suggest a chemical wash, book Saturday, invoice the deposit, hand to Mei.” |
What will an AI sales worker do?
It will reply to website chat and email enquiries, send a quotation, suggest add-ons, book the job, issue the invoice and hand the customer to your account manager. WhatsApp: coming.

How will an AI worker be trained?
Like a new hire: it will learn your business, work under supervision and earn independence as its work is checked. Its pace through each stage will depend on how its drafts hold up.
- 01
Learn
It will read your price list, policies and past conversations, connected to your customer, job and invoice records.
Approval on every action - 02
Shadow
It will draft every reply, quote and booking for approval, and learn from your team’s edits.
Approval on every action - 03
Supervised
It will handle routine work alone. Anything above your thresholds waits for approval.
Approval above thresholds - 04
On the job
It will work the role day to day within your rules, with a weekly review.
Approval on exceptions only
What stays with your team?
Judgement calls, exceptions and relationships. Your rules will decide what the AI worker does alone and what goes to a named person, and every action will be logged. This follows the approach in IMDA’s Model AI Governance Framework for Agentic AI: bound what the agent can reach, keep a named person accountable and log what it does.
The AI worker will handle
- Replies to routine enquiries
- Quotations from your price list
- Bookings into open calendar slots
- Invoices for accepted quotes
- Reminders and follow-ups
- Keeping records up to date
Your team decides
- Discounts, refunds and special pricing
- Complaints and unhappy customers
- Site visits and non-standard jobs
- Approvals above your thresholds
- The rules themselves
Which tools will an AI worker use?
The same ones your team uses, connected through one business database, so it will quote, book and invoice from your real prices, calendar and accounts. Website chat and email at launch; WhatsApp (Growth plan): coming. See how the Nerb AI Business Platform connects your data.
Google Workspace
Gmail threads, Google Calendar appointments and Google Sheets used as trackers.
WhatsApp Business
Coming: customer conversations attached to the right customer. WhatsApp AI replies are not live yet.
Xero
Quotations, invoices and payment status.
Shopify / WooCommerce
Orders, products, stock levels and customer accounts.
Custom via API
Your own systems and databases, such as a booking tool or warranty register.
Can an AI worker replace a staff member?
It is designed to take on the replying, quoting, booking and following up. Roles built on judgement, relationships and on-site work still need people.
- Coverage: it will reply at 11pm, on weekends and on public holidays the same as at 11am.
- Volume: it will handle several conversations at once.
- Consistency: every quote will use the current price list; every job, the same follow-up.
- Limits: it will use only the tools, data and rules you give it, and hand over when a person is needed.

AI agents for business: questions, answered
What Singapore business owners ask before putting AI into a real role.
We will confirm timings at launch. Setup will follow four stages (learn, shadow, supervised, on the job): your data and rules first, then a shadow period with your team approving every action. Each stage depends on how tidy your records are and how many tools are involved.
Website chat and email, where Nerb’s live chat (Foundation and Growth plans) and email assistant (Growth plan) already run. Today our clients use the live chat mainly to answer enquiries and capture leads. WhatsApp (Growth plan): coming. We will confirm the full list at launch.
Your rules will limit what it does alone, and anything above your thresholds will wait for a person. Every action will be logged against the record it used, so mistakes can be traced and corrected, and corrections feed back into how it works.
It will only use the records and tools you connect, and every action will be logged. Under the PDPA, your business stays responsible for telling customers how their data is used and getting consent where needed. The PDPC’s Advisory Guidelines on Use of Personal Data in Generative AI (July 2026) describe good practice. This is not legal advice.
No. Nerb will connect your tools and set it up. Your team keeps its usual apps and sets the rules in plain language.
Pricing will be announced at launch. Join the early access list to hear first.
