A Custom AI Chatbot for Your Business: Cost, Time & Real Expectations
When you bring up an AI chatbot, you usually hear one of two reactions: "That's expensive, it's not for us," or "It'll handle everything, it's a magic fix." Both are wrong. The truth sits somewhere in between, and it's well within reach for your SMB. This post lays out the real cost of a custom AI chatbot, how long it takes to set up, and what actually works, without the hype.
Where does the "expensive" perception come from?
When most business owners hear "chatbot," they picture either a huge enterprise project or one of those useless bots that keeps saying "I didn't understand that." Both are extremes.
Here's the reality: cost depends on what you want. A simple assistant that answers your website's FAQs and shares details like working hours and price ranges is far cheaper to build than an advanced one that pulls order status from your CRM and shows it to the customer. The key is not paying for features you don't need.
Three things that drive the cost
The budget of a chatbot project comes down mainly to three factors:
| Factor | Lower cost | Higher cost |
|---|---|---|
| Scope | FAQs, fixed information | Order tracking, bookings, personal data |
| Integration | Runs standalone | CRM, e-commerce, calendar connection |
| Language & channel | Single language, web only | Multilingual, WhatsApp + web + email |
On top of that there's a monthly running cost: the per-query fee for the AI model behind the chatbot. This line item is usually much lower than people expect, and it scales with your traffic, so you can start small and grow.
How long does setup really take?
No need to exaggerate here either. A narrow pilot can be delivered quickly once scope, access and acceptance criteria are agreed. An assistant connected to your documents, product catalog, or order system takes longer. The honest answer is that the timeline follows two things you control: how narrow the first scope is, and how quickly the access and the sample questions arrive.
The trick is to start small. Even a chatbot that handles your 20-30 most repeated questions immediately lightens a meaningful share of your support load. You expand the scope later, guided by the real questions customers actually ask.
What works, and what doesn't
To set expectations right, it helps to separate two lists.
Works well:
- Answering supported questions outside business hours, subject to the handoff rules you set
- Fixed information like hours, pricing and return policies
- Routing customers to the right department or resource
- Order and appointment status (when connected to your system)
Don't expect a chatbot alone to handle:
- Sales conversations that involve negotiation
- Emotional, sensitive complaints on its own
- Accurate, current answers when it isn't connected to your data: if it isn't, it will make things up
That last point is critical: a generic chatbot that doesn't know your business can produce wrong answers where it's unsure. The way to prevent this is to connect the chatbot to your own documents (RAG), so answers rest on your data rather than guesswork.
A hype-free, working start with Filova
At Filova, we start with a clear scope, not magic promises. We decide together which questions should go to the chatbot and which to your team, and we put the budget on the table transparently from day one. We get a small but working first version live quickly, then grow it based on real usage. Setup, integration and maintenance are on us; you focus on the results.
This is why scoping is priced separately from delivery. An Automation Audit and Plan establishes the scope and the acceptance criteria, and only then can a fixed-scope Pilot carry a figure that means anything.

Frequently Asked Questions
How much does a custom AI chatbot cost?
It depends on scope. A simple assistant that answers frequently asked questions is far cheaper than an advanced one connected to your company documents and systems. At Filova, we define the scope first, then give you a clear budget: no surprise invoices.
How long does setup take?
A narrow pilot can be delivered quickly once scope, access and acceptance criteria are agreed. An assistant that needs integrations (order tracking, or a CRM system reached through a supported API) takes longer, because the timeline follows the access you can grant and the exceptions the process turns out to have.
Will a chatbot replace my customer service team?
No. A well-built chatbot takes over repetitive questions and frees your team from routine work. Complex cases that need human judgment still go to your people. The goal isn't to replace the team, but to free their time for work that matters.
