When the workaround becomes the problem
Zoho should do the heavy lifting.
DDH Systems is an independent Zoho development and integration consultancy. We work remotely in English and French with businesses in the UK, Europe and beyond. Start with the outcome you need; a senior engineer handles the build.
Your workflow has outgrown the settings.
When a standard rule won’t do the job, we write the Deluge functions and Catalyst services your process needs.

Before you get in touch
Questions about working with DDH Systems.
What does DDH Systems build with Zoho?
DDH Systems builds Deluge automations, Zoho Catalyst backends, customer-facing applications and API integrations. We work with CRM, Billing, Bookings and Desk, as well as external tools. Explore our custom Zoho development and integration services.
How much does custom Zoho development cost?
Custom development averages €500 per day. The rate is negotiable depending on the scope and duration of your project. We agree the final rate, scope and project price in writing before work begins. Other services are quoted individually. Zoho subscriptions and third-party fees are separate.
Do I need a technical specification?
No. Start with the apps involved, the problem and the outcome you want. We check whether configuration, Deluge, an integration or a custom application fits before agreeing the work. Please do not send passwords or customer data in your enquiry.
Can you work with our existing Zoho partner or admin?
Yes. DDH Systems can take on a specific development or integration alongside your current team. We agree who owns each part and document the changes so the work can be maintained afterwards.
Who owns the delivered code and documentation?
You keep the delivered code and documentation. No ongoing contract is required for a project. Improvements and ongoing support can be covered by a separate monthly on-call retainer if you need one.
