A customer service AI chatbot development service for websites is an agency or developer that builds a custom chatbot for you, and for most websites a no-code platform does the same job for $59 a month with no build phase. Hire a development service when the chatbot must act inside your own systems. Use a platform when it only needs to answer questions from your content.
TL;DR
- Chatbot development agency: best for custom workflows across your CRM, orders or billing. Clutch says a simple proof-of-concept often starts around $10,000 and a custom build commonly takes 8 to 12 weeks.
- SiteGPT, a no-code platform: best for a website chatbot without a development project. It costs $59 a month billed monthly, or $39 a month billed yearly, and you can test it on a 7-day free trial.
- Freelance developer on an AI API: best for a chatbot inside your own product. Upwork lists chatbot developers at $30 to $61 an hour, so an 80-hour build costs $2,400 to $4,880.
- In-house developer: best when your team must own the code. 140 hours at the US median of $64.44 an hour is $9,021.60 in wages.
- Compliance: with a custom build, every vendor in the stack must sign your BAA or DPA. SiteGPT signs a BAA and a DPA on Enterprise only.
Key takeaways: chatbot development service vs no-code platform
Route | Best for | Up-front cost | Time to launch |
Chatbot development agency | Custom workflows across several systems | Often from $10,000 for a proof-of-concept (Clutch) | Commonly 8 to 12 weeks (Clutch) |
A website chatbot without a development project | $0, then $59 a month, or $39 a month billed yearly | No build phase. Test on the 7-day trial | |
Freelance developer on an AI API | A chatbot inside your own product | $2,400 to $4,880 for an 80-hour example build | About 2 weeks of full-time work for 80 hours |
In-house developer | Teams that must own the code | $5,155.20 in wages for 80 hours at the US median | Depends on the team's other work |
What is a customer service chatbot development service?
A customer service chatbot development service is a company or freelancer that designs, builds and maintains a chatbot for your business. Clutch lists 9,981 companies in its chatbot category. They handle conversation design, training on your content, connections to your CRM, helpdesk and channels, then testing, launch and tuning.
The alternative is a no-code platform. A platform has already built the crawler, the answer engine, the chat widget and the dashboard. You add your content and paste the widget on your site.
The question behind most searches for a development service is build or buy. This guide answers it with costs and timelines. Platforms are ranked one by one in AI chatbot for customer service: 7 best platforms.
How the four routes were ranked
The four routes were ranked for one scenario: a business that searched for a chatbot development service for its website. Four criteria set the order and the labels.
- What the chatbot can do. Answer questions only, or also act inside other systems.
- First-year cost. The build cost plus twelve months of running cost, from published rates.
- Time to launch. From the first decision to a chatbot customers can use.
- Who maintains it. Your team, a vendor, or a contractor on a retainer.
No route is the best pick for every business, so each route has a "best for" label. SiteGPT publishes this guide and is one of the four routes. Its limits are listed with the same weight as the others.
The 4 ways to get a customer service chatbot built for your website
1. Chatbot development agency: best for custom workflows across several systems
A chatbot development agency builds a chatbot to your specification and connects it to your own systems. This route fits a business whose chatbot must look up orders, update a CRM record or follow a process no product supports.
What it costs
Clutch says minimum project sizes among its listed firms run from about $1,000 to $100,000 or more. Hourly rates run from under $25 to about $200, and $50 to $99 an hour is the most common band for established AI developers. A simple proof-of-concept often starts around $10,000, and enterprise builds can reach $250,000.
How long it takes
Clutch says a custom chatbot build typically takes 8 to 12 weeks. Builds with several integrations, training on large amounts of your own data, or a security review take longer.
Pros
- Built around your workflows, with connections to your CRM, helpdesk and billing tools
- Your data rules and hosting choices are part of the specification
- The agency can keep tuning the chatbot under a support contract
Cons
- The highest up-front cost of the four routes
- Two to three months before customers see anything
- Each connected system adds upkeep, because a change in that system can break the chatbot
- Some agencies build on a platform and resell it under their own brand. Ask what the chatbot runs on and who owns the code.
Best for
A chatbot development agency is best for a company with a workflow no platform supports and a budget for ongoing development.
2. SiteGPT: best for teams that want a website chatbot without a development project
SiteGPT is a no-code AI chatbot trained on your website and business content. It answers customers in 95+ languages and hands the chat to a person when needed. There is no build fee and no development project.
Key features
- Trains on website URLs, sitemaps, files and raw text, plus Google Drive, Dropbox, OneDrive, Box, Notion, GitHub and YouTube
- Auto refresh keeps answers current: monthly on Growth, weekly on Scale, daily on Enterprise
- Escalation to a person, with an iOS app that alerts your team when a visitor asks for a human (Growth and above)
- Chat integrations with Slack, Crisp, Messenger, Google Chat, Freshdesk Messaging and Zoho SalesIQ from Growth, and a Zendesk AI Agent from Scale
- API access from Growth, and custom features and integrations on request on Enterprise
What it costs
Plan | Billed monthly | Billed yearly (per month) | Messages a month | Chatbots |
Starter | $59 | $39 ($468 a year) | Up to 4,000 | 1 |
Growth | $129 | $79 ($948 a year) | Up to 10,000 | 2 |
Scale | $429 | $259 ($3,108 a year) | Up to 40,000 | 3 |
Enterprise | Custom | Custom | Custom | Custom |
Message counts are GPT-4.1-mini messages, or one tenth as many GPT-4.1 messages. Packs of 5,000 extra messages cost $59 a month billed monthly, or $39 a month billed yearly. Source: SiteGPT pricing.
How long it takes
SiteGPT has no build phase. Setup means adding your content, testing the answers and pasting the widget on your site. The 7-day free trial is long enough to run that test on your own pages. The trial needs a credit card.
This walkthrough shows how content goes into a SiteGPT chatbot.
Pros
- $0 up front. A year of Starter billed yearly costs $468, under 5% of a $10,000 agency proof-of-concept.
- The widest set of content sources of the four routes, with no ingestion code to write
- Upkeep is part of the plan. Growth and above re-sync content on a schedule.
- A signed BAA and DPA are available on Enterprise
Cons
- It answers from your content and hands off to people. It does not run custom steps inside your order system or CRM.
- No Intercom or HubSpot integration today, and no visual flow builder
- Starter refreshes content manually, allows 10 files and has no chat integrations
- No free plan. The 7-day trial needs a credit card.
- Cloud file connectors and chat integrations are not available in a HIPAA workspace, so content goes in by upload and customers use the chat on your website. The HIPAA workspace docs list every change.
Rating
SiteGPT holds 4.9 out of 5 from 12 reviews on G2.
Best for
SiteGPT is best for businesses whose answers already live on their website and in their documents, and that want a chatbot live without a development project.
SiteGPT does not sell a build service. It runs an agency program that lets agencies white-label SiteGPT for their clients, from a $500 a month minimum credit commitment. An agency you hire may deliver a chatbot built this way.
3. Freelance developer on an AI API: best for a chatbot inside your own product
A freelance developer can build a chatbot on an AI model API, such as OpenAI's, and you pay the model provider by usage. This route fits a team that wants the chatbot inside its own app, with its own interface.
The developer builds five parts: content ingestion, retrieval over your content (RAG), the chat interface, a content refresh job and a handoff to a person.
What it costs
Upwork lists median rates for chatbot developers at $30 to $61 an hour. This example uses 80 hours to build and 5 hours a month of upkeep.
Line | At $30 an hour | At $61 an hour |
Build, 80 hours | $2,400 | $4,880 |
Upkeep, 60 hours a year | $1,800 | $3,660 |
Model usage, 4,000 answers a month | $141.60 a year | $141.60 a year |
First-year total | $4,341.60 | $8,681.60 |
Model usage assumes gpt-6-luna at $0.10 per 1M input tokens and $0.50 per 1M output tokens, 3,000 input and 300 output tokens per answer, and one file search call at $2.50 per 1,000 calls. That is about $2.95 per 1,000 answers. Hosting is billed by your cloud provider and is not included. The full token math is in the chatbot cost guide.
How long it takes
80 hours is about two weeks of full-time work for one developer. The hour count is an example budget. Replace it with your developer's quote.
Pros
- The chatbot can live anywhere in your product, with your own interface
- You own the code
- Model usage is the smallest line in the budget
Cons
- Every content change, bug and model update needs the developer again
- One freelancer is a single point of failure
- Upkeep costs $1,941.60 a year at $30 an hour, which is more than SiteGPT Starter on monthly billing at $708
Best for
A freelance build is best for a product team that wants a chatbot inside its own app and has a developer on call for later changes. The build steps are in the guide to training ChatGPT on your own data.
4. In-house developer: best for teams that must own the code
An in-house build is the same work as the freelance route, done by your own staff. It fits a company with an engineering team and data rules that keep the work inside the business.
What it costs
The US Bureau of Labor Statistics lists median pay for software developers, quality assurance analysts and testers at $64.44 an hour in 2025. The same 140 hours as the freelance example cost $9,021.60 in wages, or $9,163.20 with model usage. Benefits and the time taken from other projects come on top.
How long it takes
The build takes the same hours as a freelance build. The calendar time depends on how much of the developer's week the chatbot gets.
Pros
- Full control of code, data and hosting
- The team that maintains it also knows your systems
Cons
- The highest hourly cost of the custom routes in this guide
- Every hour on the chatbot is an hour off your own product
Best for
An in-house build is best for a company whose security or product needs rule out outside vendors.
Chatbot development cost compared: agency, freelancer, in-house and platform
A customer service chatbot costs $708 in its first year on SiteGPT Starter billed monthly, about $4,342 to $8,682 with a freelance developer, and from about $13,142 with an agency, using the example budgets in this guide.
The agency figure uses Clutch's $10,000 proof-of-concept rule of thumb, plus 5 hours a month of upkeep at $50 to $99 an hour and the same model usage. The table carries every route over three years, with prices and volumes held flat.
Route | Year one | Each later year | Three-year total |
SiteGPT Starter, billed yearly | $468 | $468 | $1,404 |
SiteGPT Starter, billed monthly | $708 | $708 | $2,124 |
SiteGPT Growth, billed monthly | $1,548 | $1,548 | $4,644 |
Freelance build at $30 an hour | $4,341.60 | $1,941.60 | $8,224.80 |
Freelance build at $61 an hour | $8,681.60 | $3,801.60 | $16,284.80 |
In-house build at $64.44 an hour | $9,163.20 | $4,008 | $17,179.20 |
Agency, upkeep at $50 an hour | $13,141.60 | $3,141.60 | $19,424.80 |
Agency, upkeep at $99 an hour | $16,081.60 | $6,081.60 | $28,244.80 |
Three results stand out.
- A $10,000 agency proof-of-concept equals about 169 months of SiteGPT Starter at $59, or about 256 months at the yearly rate of $39.
- Over three years, the cheapest freelance build costs $6,100.80 more than SiteGPT Starter on monthly billing.
- The custom routes cost more every year after launch too, because upkeep hours cost more than the plan they replace.
Message volume changes the platform side. SiteGPT Starter covers up to 4,000 GPT-4.1-mini messages a month, and Growth covers up to 10,000. Vendor-by-vendor prices at higher volumes are in the AI chatbot pricing comparison.
How long does chatbot development take?
Chatbot development takes 8 to 12 weeks for a typical custom build from a development company, according to Clutch. A no-code platform skips the build, so the time goes into adding content and testing answers.
Phase | Agency or custom build | No-code platform |
Scoping and quote | Discovery calls and a written specification | Sign up for the trial |
Build | Conversation design, ingestion, retrieval, interface and integrations | None. The product already exists. |
Content | Write ingestion code for each source | Add URLs, a sitemap, files or connected drives |
Testing | Test plan, fixes and often a security review | Ask real customer questions and fix gaps in the content |
Launch | Deploy to your hosting | Paste the widget code on your site |
Total | Commonly 8 to 12 weeks (Clutch) | Testable within the 7-day trial |
Whichever route you take, the test step is the same. The steps for scoping, content and testing are in how to make a chatbot.
When to hire a chatbot development service, and when not to
Hire a chatbot development service when the chatbot has to do work a platform cannot: take actions in your own systems, run inside your product, or meet data rules no vendor will sign. Skip it when the chatbot's job is to answer customer questions from your website and documents.
Clutch gives a similar rule of thumb. It suggests off-the-shelf tools for simple FAQ deflection on a tight budget, and a custom build for proprietary data, regulatory compliance or complex multi-system workflows.
If you need... | Pick... | Why |
Answers from your website, help center and files | 12+ content sources, no build fee, $59 a month | |
A chatbot live this week | No build phase, 7-day free trial | |
Order lookups, refunds or CRM updates inside the chat | A chatbot development agency | Custom integrations with your own systems |
A chatbot inside your own app | A freelance or in-house developer | Your interface, your code, about $2.95 per 1,000 answers in model usage |
Code that never leaves your company | An in-house developer | Full control of code, data and hosting |
A branded chatbot to resell to clients | White-label widget, from a $500 a month credit commitment | |
A signed HIPAA BAA | SiteGPT Enterprise, or a build where every vendor signs one | SiteGPT signs a BAA during enterprise onboarding |
Healthcare buyers can compare vendor terms in HIPAA compliant AI chatbots.
What to ask a chatbot development agency before you sign
Ask a chatbot development agency six questions before you sign. The answers decide the real cost after launch.
- What will the chatbot run on? A custom stack, an AI API, or a platform the agency resells.
- Who owns the code and the data? Get it in the contract, including what happens if you leave.
- What does upkeep cost? Ask for the monthly hours or retainer as well as the build quote.
- Who pays the model and hosting bills? Usage and hosting are billed every month.
- How does a customer reach a person? Ask to see the handoff and where the transcript lands.
- Will every vendor sign your BAA or DPA? This matters for healthcare and EU customers.
Clutch also recommends checking verified reviews from clients with a similar use case, and case studies with measurable outcomes.
Chatbot development service FAQ
Basics
What does a chatbot development service do?
A chatbot development service designs, builds, connects and maintains a chatbot for your business. The work covers conversation design, training on your content, integrations with your CRM, helpdesk and channels, testing, launch and tuning.
Is a no-code chatbot as good as a custom one?
For answering customer questions from your website and documents, a no-code platform does the same job without a build. A custom chatbot is better when it must take actions in your own systems or run inside your product.
Cost
How much does chatbot development cost?
Clutch says custom chatbot projects generally start at a $1,000 to $10,000 minimum and reach $100,000 to $250,000 or more for enterprise systems. A freelance build at $30 to $61 an hour costs about $4,342 to $8,682 in year one in this guide's example. SiteGPT Starter costs $708 a year billed monthly.
How much does a chatbot developer charge per hour?
Chatbot developers on Upwork charge median rates of $30 to $61 an hour. Clutch says $50 to $99 an hour is the most common band for established AI development firms. US median pay for software developers is $64.44 an hour.
Timeline
How long does it take to build a customer service chatbot?
A custom build from a development company commonly takes 8 to 12 weeks, according to Clutch. A freelance build of 80 hours is about two weeks of full-time work. A no-code platform has no build phase, so you can test it within a 7-day trial.
What slows a chatbot project down?
Clutch names three drivers: integration complexity, the amount of your own data the model is trained on, and the depth of testing before launch. Security reviews add time for regulated industries.
Choosing a route
Does SiteGPT offer a chatbot development service?
No. SiteGPT is a no-code platform. It runs an agency program that lets agencies white-label SiteGPT for their clients, and its Enterprise plan includes custom features and integrations on request.
Can I switch from a platform to a custom build later?
Yes. A platform chatbot shows which questions customers ask and where the content has gaps. That record helps scope a custom build later. The chatbot itself has to be rebuilt if you change vendors.
