Custom AI chatbot development and voice agents in the UK

Bots and voice agents trained on your business. They answer, qualify and book, then hand over when a person is needed.

In short

A custom AI chatbot or voice agent answers enquiries by chat or phone using your own information, qualifies them and books the next step, handing over to a person when needed. APPS 365, a UK software company, designs and builds them from £999, with a fixed written quote.

When enquiries outrun your team

Slow replies can cost you work, and a scripted bot rarely helps.

Calls go unanswered when the line is busy or the office is shut.

A voice agent can pick up, take a booking and send your team a summary.

Staff answer the same questions all day.

A chatbot trained on your pages and policies deals with the routine ones.

You tried a scripted bot and people gave up on it.

A custom build understands ordinary language, uses your wording and admits when it does not know.

Why build it around your business

The channels people use

Website chat, WhatsApp, Microsoft Teams and the phone, planned as one service.

Linked to your systems

It can connect to your CRM, calendar, booking system or helpdesk.

A clean handover to a person

You set when it passes a conversation on, and your team gets the details.

What a build usually includes

Your written quote sets the scope. A typical project includes:

  • Training on your approved content, wording and tone
  • Qualifying questions and booking flows
  • Connections to your CRM, calendar or helpdesk
  • Testing with real questions, then agreed support

AI voice agents: answering calls and taking bookings

A voice agent is an AI that talks on the phone. It can answer calls, take bookings and pass the caller or a summary to your team.

Outbound calls go only to people who have opted in. UK PECR requires prior consent for AI voice marketing calls, so we do not offer AI cold calling. If you want an agent to ring your own contacts, we first look at how each person gave consent.

You choose the voice and tone, including UK English voices. We advise telling callers at the start that they are speaking to an AI, and telling them if the call is recorded.

Frequently asked questions

How much does a custom AI chatbot cost in the UK?

Our chatbot and voice builds start from £999, and the fixed quote comes after a free call. The number of channels and systems moves the price. Monthly running costs apply.

Can an AI voice agent book appointments?

Yes, a voice agent can take a booking during a call if it is connected to your calendar or booking system. Anything unusual goes to your team.

Is an AI voice agent legal under PECR and UK GDPR?

It can be, but it depends on how you use it. AI voice marketing calls need prior consent under UK PECR, so we only build outbound calling to people who opted in. We discuss UK GDPR and recording notices with you.

Will callers know it is an AI?

Yes, we recommend the agent says it is an AI at the start of each call, so people can ask for a person straight away.

Should I buy an off-the-shelf chatbot or have one built?

Buy one if you only need common questions answered on your website and a low-cost tool already does that. Have one built when it must reach your own systems, follow your rules or work across channels.
