How to choose

Which one fits your business?

Choose HiyaCalls if…

  • You’re an SMB and don’t need a Coca-Cola-grade enterprise service
  • You want a predictable monthly cost rather than per-minute billing
  • You handle a high volume of routine calls (viewings, bookings, enquiries)
  • You want every call documented in writing in your inbox

Choose JAM if…

  • You’re a large enterprise where ISO 9001 and 40+ years of track record are a procurement requirement
  • Your calls are complex and benefit from a deeply trained human receptionist team
  • You prioritise pedigree and enterprise references over modern AI capability
  • You’re comfortable with per-minute billing for the human quality it buys

Comparison FAQ

Common questions.

Why would I switch from JAM to HiyaCalls?
You probably wouldn’t if you’re a large enterprise with complex needs and a JAM relationship that works. If you’re an SMB paying per-minute and your call volume is growing, the maths usually favours bespoke AI pricing, plus the automatic written summaries are a workflow upgrade most clients tell us they wish they’d had years ago.
JAM has 2,000+ five-star reviews. HiyaCalls is new, is that a risk?
Yes, that’s a fair concern. We’re newer to the UK market. The way we offset it: a transparent demo where you hear the AI answer a sample call for your business, references from comparable clients on request, and a short rolling contract so there’s no long-term commitment if it doesn’t work for you.
Can HiyaCalls handle complex calls the way JAM does?
For routine business calls, viewings, valuations, bookings, message-taking, lead capture, tenant queries, yes, equally well. For genuinely complex, high-stakes calls (e.g. legal escalations, crisis comms), we’ll be honest: a deeply trained human team has the edge. We can route complex calls to a fallback human if you want.
