The Zoho team businesses call when it matters
H4Z is a UK-based Zoho consultancy serving clients worldwide. Two complaints come up in almost every first call with a new client: the last agency was slow and nobody took responsibility when things broke. We built our service around fixing both.
What working with us looks like
Built for speed
A developer assigned within 24 hours. Emergencies answered within 30 minutes during UK business hours. Both numbers are published, so hold us to them.
Whole-suite depth
We work across every Zoho application - CRM, One, Creator, Books, Desk, Analytics, Flow, Sites and beyond - so your whole system is designed as one architecture.
AI, done practically
ChatGPT and Zia working inside your workflows, custom AI agents, Zoho MCP. We add AI where it saves real hours - not where it makes a demo look good.
Documented work
Every change we make is written up and explained in plain English. You own your system and understand it, so you’re not tied to whoever built it.
Transparent pricing
Our engagement models and prices are published openly. Quotes are written and scope changes are agreed before they’re billed.
UK-based, worldwide
Our team works from the UK; the company, H4Z Development Services Limited, is registered in Gibraltar. Our hours suit Europe and most of the US East Coast day.
How we work
Every engagement starts with a free discovery consultation. You describe the problem. We ask the awkward questions about data and process. You leave with a clear picture of what good looks like, whether or not you hire us.
From there you choose the engagement model that fits: hourly work for small jobs, a dedicated developer for ongoing builds, a fixed-scope project with a written specification, or a support retainer with emergency cover included.
We design before we build. Most expensive Zoho problems trace back to systems that grew feature by feature with no architecture. A Zoho One rollout, a migration, a rescue of something half-built: in every case we start with how data should flow through your business and work backwards.
And when something breaks, there’s a published 30-minute emergency response.
Who you'll deal with
H4Z is led by Lewis Weldon, Founder and Lead Developer. Lewis still spends most of his week inside client systems - recent work includes the shared ownership completion automation for Heylo Housing and the application-to-CRM pipeline for Nationwide Finance. When you book a discovery call, he's the one you talk to.
