You've got two very different choices: DIY tools you configure yourself, or a done-for-you service with a fixed price. We built this page to compare them honestly — including our own, with its weaknesses stated.
The big telecoms brands (BT, RingCentral, GoTo) sell phone systems with AI bolted on — powerful, but priced and built for offices with IT support. The new wave of AI tools (SynthFlow, IONOS' offering, 3CX's add-ons) are cheaper, but you write the scripts, wire up the diary, and become the support desk. A third option is a service that's set up for you — which is what we do. The right choice depends on how much time you want to spend being an installer.
Prices are typical UK advertised rates at time of writing — always check current pricing.

Honest caveats: the big brands have deeper phone features (hold queues, handset hardware) we don't offer. DIY tools can work out cheaper at very low call volumes if you enjoy setting them up. Our £149 fixed price suits businesses taking roughly 50–500 calls a month; very high volumes may suit an enterprise platform better. Names and prices are trademarks of their respective owners; this page is an independent comparison.
If you want hardware and hold queues, go big-brand. If you want to tinker, the DIY tools are genuinely good. If you want every call answered and the jobs booked in — without becoming an AI installer — that's what we built.
The free trial puts our receptionist on your own number for a couple of weeks. Ring it from the van, see the summary arrive. If it isn't for you, that's a useful data point — and if it is, it moves onto the £149/month fixed plan with everything tailored to your business.
