A small business does not need most of what an AI chatbot for customer support is sold on. Sentiment analysis, intent models, integration catalogues — that furniture exists for support departments with headcount. When the whole department is you and a shared inbox, the list is shorter: answers drawn from your own documents, a source shown under every reply, a polite handoff when the bot is out of its depth, and a price that behaves the same in a busy month as a quiet one.

That list is worth writing down before you shop, because the market will not volunteer it. Most comparison pages are written by the vendors in them — ours included, which is why this one shows its working. Here is when a chatbot is worth buying at all, what to ask before you pay, and what the numbers look like, with ours as the worked example.

Does a small business need an AI chatbot for customer support?

Not always. If you receive a handful of questions a week, a clear FAQ page and a shared inbox will serve you better than any bot, and cost nothing. A chatbot starts to earn its keep when the same questions arrive over and over, and keep arriving after you have locked up for the evening. Opening hours, returns, delivery dates, where the reset-password button hides: if you can predict most of tomorrow’s inbox from last week’s, you are paying yourself to type the same paragraph twice a day.

The second condition is less obvious: the bot needs something to stand on. A chatbot that answers from your documents is only as good as the documents, and if the answers currently live in your head, no tool will retrieve them. Write the pages first; our guide on writing help-centre articles your AI agent can actually use is the place to start. Then treat the bot as the front desk that reads them aloud at 2 am.

The questions that separate a useful bot from a liability

Ask every tool on your shortlist the same five questions. The answers matter less than whether they are answered plainly.

  • Where do answers come from, and can the customer see it? The right answer is your content, with the source named beneath each reply. An answer that cites nothing has to be taken on faith — by you and by your customer.
  • What happens when it does not know? The honest failure mode is a handoff to a human; the dishonest one is a confident guess. Ask to see an escalation before you pay, because it is where a support tool shows its character.
  • What does the pricing count? A “conversation” can mean one message, one session or one visitor a month depending on the vendor, so the same headline number can differ tenfold in practice.
  • What happens over the limit? Look for the behaviour, not the adjective: does the bot stop answering mid-month, and what does the next thousand conversations cost?
  • What happens to your data? You are about to hand a tool your policies and your customers’ questions. Whether any of it trains anyone else’s models deserves a written answer, and the answer should be no.

How to read chatbot pricing

Our own price card is the one we can annotate line by line, and the shape generalises. Serochat’s Starter plan is £49 a month — one chatbot, one connected knowledge source, 500 conversations a month on fair-use terms. A conversation is one visitor’s chat session in a calendar month, however many messages it contains, and follow-ups in the same session are not counted again. Spread evenly, 500 a month is roughly 16 conversations a day, which covers more small businesses than the number suggests.

Fair use is where vendors usually go vague, so here is ours in full. Go over the allowance and the bot keeps answering while we email you; a hard pause arrives only at roughly 15% over, and it lifts the moment a credit pack is applied or the month resets. Packs are one-time top-ups that do not expire with the month, and 1,000 conversations cost £30. We would rather print that paragraph than call the allowance unlimited.

The Team plan is £149 a month for up to 3 chatbots, 5,000 conversations a month and unlimited knowledge sources, and annual billing on either plan is ten months’ price for the year — £490 on Starter. Two costs no price card shows: your time, which is an afternoon to connect content and a half hour a week reading transcripts; and, on Starter, a small “Powered by Serochat” line on the widget, which Team removes. Every paid plan starts with a 7-day trial, no card needed, and the trial is the cheapest research you will do.

Where Serochat fits, and where it does not

We built Serochat for the buyer this article describes, so read this section as a pitch with the receipts attached. It answers from the content you connect: help-centre pages, Google Drive or Notion, a Zendesk Help Center, uploaded PDFs. Under every reply it names the source it drew from, and an answer it cannot verify against that source is discarded rather than shown — the visitor is offered a human instead, by email or a live operator takeover. The embed is one script tag; the home page says “live in 10 minutes”, and the honest gloss is that the tag takes the 10 minutes and connecting your content takes the afternoon.

Now the disclosure. Serochat answers questions from documents; it does not reach into your other systems, so it cannot check an order status, process a refund or change a booking. If most of your inbox is “where is my parcel?”, a bot grounded in policy pages will help less than you hope. A website source indexes up to 25 pages you pick; it does not crawl your whole site, which rewards a tidy help centre over a sprawling one. And there is no multilingual feature: if your customers write to you in three languages, other tools will serve you better. Better you find that out here than three days into a trial.

Common questions

How much does an AI chatbot cost for a small business?

Serochat is £49 a month on the Starter plan and £149 a month on Team, each with a 7-day free trial and no card needed. Across the market, treat any figure as unreadable until you know what a conversation means and what happens over the allowance; two tools with the same headline price can cost very different amounts by December.

Can I set one up without a developer?

For Serochat, yes. The widget is one script tag pasted before the closing body tag, and most site builders have a box for exactly that. Content is connected with pickers and uploads, nothing to code: choose up to 25 pages from your site, pick files from Drive in Google’s own picker, or upload PDF, DOCX, TXT or MD files up to 25 MB each.

Will it make things up in front of customers?

Some chatbots will, and it is the single best question to shop with. Ask what happens when the tool finds nothing to answer from. Serochat checks every reply’s citation against the passages it actually retrieved; a reply whose citation cannot be verified is thrown away and the visitor is offered a human instead. No vendor can make fabrication impossible — grounding and checking make it rare, and visible when it happens.

What happens to the questions it cannot answer?

They become your to-do list, which is the point. When Serochat cannot answer, the visitor sees your escalation message and a “Talk to a human” button, and the conversation reaches your team by email or a live takeover. Unanswered questions are then clustered each night into a training queue: write the answer once and every future asker gets it directly, with the source shown as usual.

A chatbot earns its place in a small business the way a first hire does: by handling the repeatable work honestly and knowing when to come and find you. Buy the one that shows its sources and admits its gaps. The confident one that never says “I don’t know” will cost you more than its subscription.
