Zoho CRM implementation
CRM set up around how you sell, with migration and training.
Deluge
Deluge development
Deluge is the scripting language behind Zoho's automation: custom functions in Zoho CRM and Books, workflows in Creator, and calls to external APIs. We write Deluge that is readable, handles errors, and can be maintained by the next person who opens it.
Is this for you?
When you need a Deluge developer
Built-in automation stops short
Workflow rules can't do the calculation, lookup or cross-module update you need.
Zoho apps need to talk to each other
CRM, Books, Creator and Desk records should update each other automatically.
An external API must be called
Pull or push data to another system from inside Zoho.
Existing scripts are failing
Functions time out, hit limits or break silently, and nobody knows why.

Technology
Where Deluge runs
Deluge runs inside most Zoho products, each with its own triggers and limits. We design around those limits, use Zoho connections for secure authentication, and move heavy processing to Zoho Catalyst or an external service when a script would otherwise struggle.

How it works
How Deluge work runs
Small, well-defined scripts can often be delivered within days; larger automation work follows the same staged process as our other projects. We confirm the estimate after seeing your setup.

FAQs
Frequently asked questions
Deluge (Data Enriched Language for the Universal Grid Environment) is Zoho's scripting language. It is used to write custom functions, workflows and integrations across Zoho products such as CRM, Creator, Books and Desk.
Yes. We review the scripts, explain what is going wrong, and fix the problems in order of impact. Common issues include missing error handling, execution limits and hard-coded values.
Yes. Deluge can call external REST APIs with invokeUrl, using Zoho connections to handle authentication securely. For high volumes or complex logic we may recommend a small middleware service instead.
We charge US$15 per hour. Fixed-price projects are quoted from the estimated days and complexity: you can get an indicative figure from the calculator on our pricing page, and after a discovery call we send a written proposal with scope, timeline and cost before any work starts.
Yes. Every function is commented, and we provide a short summary of what each script does, what triggers it and what to check if it fails.
