:: AI services / AI chatbot development

An AI chatbot development company for bots that know your business

We build custom chatbots that answer from your own help centre, product data and policies, in your tone of voice, and pass the conversation to a person when they should. No scripted decision trees and no made-up answers.

Answers from your own content

Website, app, WhatsApp, Slack

Clean hand-off to your team

:: What we do

Custom chatbot development

We pick the channel and the knowledge sources first, then build the bot around them.

01

Customer support chatbots

Answer order, billing and product questions around the clock and open a ticket with the full conversation when a person is needed.

02

Website and lead chatbots

Answer pre-sales questions, qualify visitors and book meetings straight into your calendar or Salesforce.

03

Internal knowledge chatbots

Let staff ask HR, IT and policy questions in Slack or Teams and get answers with links to the source document.

04

WhatsApp and messaging bots

Order updates, appointment booking and reminders on the channels your customers already use.

05

In-app assistants

A chat panel inside your web or mobile app that knows the user’s account and can guide them through tasks.

06

Multilingual chatbots

One bot that answers in your customers’ languages, with answers checked against the same source content.

:: Use cases

Customer support and order questions

Answers about orders, returns and delivery from your store and help centre, and passes harder cases to a person with the full conversation.

:: Step by step

How to build an AI chatbot that customers trust

Most chatbots fail because they guess, not because the model is weak. This is the order we build in, so the bot answers from facts and knows when to stop.

01

Decide the job and the limits

Write down the questions the bot should answer, the actions it may take, and the topics it must hand over. A narrow, clear job beats a bot that tries to do everything.

02

Collect and clean your content

Gather help articles, policies, product data and past support replies. Remove outdated pages and fix contradictions, because the bot will repeat whatever it is given.

03

Ground answers in your content

Use retrieval so the bot looks up the right passage before it answers, and cites it. If nothing relevant is found, it says so instead of making something up.

04

Connect the systems it needs

Order lookups, bookings, CRM records or ticketing. Each connection gets the narrowest access the task needs, with confirmation before anything changes.

05

Design the handover to people

Decide when the bot passes to a person, how the conversation arrives in your helpdesk, and what customers see outside working hours.

06

Test with real questions

Run a few hundred real customer questions through it, score the answers, and fix the content or instructions behind every wrong one before launch.

07

Launch, watch and improve

Start on one page or channel, review conversations every week, add missing answers and expand once the numbers hold up.

:: How it works

How we build a chatbot

The model is the easy part. The quality comes from the content and the testing.

01

Gather the knowledge

Help articles, FAQs, policies, product data. We clean and structure them so the bot can find the right answer.

02

Design the conversation

Tone, greetings, when to ask follow-up questions and exactly when to hand over to a person.

03

Test with real questions

Hundreds of past customer questions, scored for accuracy before the bot goes live.

04

Launch and tune

Weekly review of unanswered questions and low ratings, and content updates to close the gaps.

:: Cost and timeline

How much does chatbot development cost?

Typical prices for our chatbot projects, based on a senior team at $25 to $35 an hour. You get a fixed quote after a short discovery call.

Starter chatbot

$5k – $12k

Multi-channel assistant

$12k – $30k

What it costs to run

For most business websites, model and hosting costs run from tens to a few hundred dollars a month, depending on traffic and conversation length. Channels like WhatsApp add their own per-message fees. We size this with you before build.

Whether it takes actions or only answers

Volume and quality of your existing content

Handover and helpdesk requirements

:: Quality checklist

What separates a useful chatbot from an annoying one

Customers forgive a bot that says “let me get a person”. They don’t forgive one that confidently gets it wrong. This is what we build in, and what we avoid.

Built into every chatbot

Answers only from your approved content

Shows sources or links for its answers

Clear handover to a person, with context

Knows your opening hours and escalation rules

Conversation logs and weekly quality review

Privacy notice and data retention settings

Mistakes we help you avoid

Bots that invent prices, policies or dates

Endless loops with no way to reach a person

Launching on every channel at once

Outdated content nobody owns

No measure of what customers actually ask

:: Why Sterling
