Our Zoho Development Process
A six-step rhythm engineered so your Marketplace extension clears Zoho review and your CRM customisations age well.
Discovery & Zoho Audit
We audit your Zoho One subscription, existing customisations, data model, and integration surface — and define the extension scope and listing strategy.
Architecture & Data Model
Custom modules, layouts, fields, profiles, validation rules, and workflows — designed for performance, permissions, and Marketplace portability.
Deluge & Widget Build
Deluge functions, custom buttons, schedules, widgets, Pages, and Catalyst services — with proper logging, error handling, and idempotency.
Security & Listing Prep
OAuth scopes minimised, secrets vaulted, error paths logged, and Marketplace listing copy, screenshots, demo videos, and pricing prepared.
Marketplace Submission
Submit the extension to Zoho Marketplace, respond to reviewer feedback, and coordinate launch — including pricing, support email, and refund policy.
Customer Support & Iteration
Patch versions, feature releases, customer support runbooks, and migration scripts when Zoho updates an API version.
Why Choose Hendoi for Zoho
Six commitments that decide whether your Zoho extension ages well — or becomes 1000 lines of Deluge nobody can debug.
Deluge-Fluent Engineering
We write Deluge like it is a real programming language — error handling, logging, modularity, and idempotency built in. No 1000-line "scripts" that nobody can debug.
Catalyst When Deluge Is Not Enough
For heavy lifting — long-running jobs, ML inference, file processing — we offload to Zoho Catalyst with proper auth, scaling, and observability.
Marketplace ISV Experience
We know the Zoho Marketplace review process, OAuth scopes, listing requirements, and billing patterns — your extension will not stall in submission.
Cross-App Integration
CRM + Books + Inventory + Desk + Creator working as a single workflow — with Webhooks, Functions, Flow, and Catalyst stitching it together cleanly.
Security & Scope Discipline
OAuth scopes minimised to the smallest set, secrets in Catalyst environment variables, and audit logging built in — your Marketplace listing passes review.
Transparent Engagement
Weekly demos in your Zoho org, direct access to engineers, milestone-based pricing with Marketplace review timelines documented, predictable burn.

Frequently Asked Questions
Common questions Zoho-heavy teams and Marketplace ISVs ask before engaging a development partner.
Can you list our extension on Zoho Marketplace?
Yes — we build Marketplace extensions end-to-end. Architecture, Deluge/widget code, OAuth scope review, listing copy, demo videos, pricing setup, and submission coordination with Zoho reviewers.
When should we use Deluge vs Catalyst?
Deluge for in-app automation, simple integrations, and workflows under 30 seconds. Catalyst for long-running jobs, ML inference, heavy file processing, scheduled batch work, and any time you need real backend horsepower. We pick based on the workload — not religion.
Do you customise Zoho CRM modules?
Yes — custom modules, layouts, fields, profiles, roles, validation rules, workflows, custom buttons, related lists, and widgets. We document every change so your admin can maintain it after handoff.
Can you integrate Zoho with our existing ERP or payment gateway?
Yes — REST APIs, Webhooks, Zoho Flow, and Catalyst services. We handle OAuth flows, retries, idempotency, error handling, and observability. Integration patterns are documented.
What about Zoho Creator?
We build Creator apps — forms, reports, Pages, mobile apps, Deluge workflows, and integrations with the rest of your Zoho One stack. Great for industry-specific workflows that do not fit standard CRM.
How long does a Marketplace listing take?
A focused extension: 6-12 weeks build, plus 2-4 weeks for Marketplace review and listing approval. Larger extensions take longer. We share a milestone plan with review timelines documented up front.
How do you handle data security and OAuth scopes?
OAuth scopes are minimised to the smallest set the extension actually needs. Secrets live in Catalyst environment variables. Audit logs and error logs are persisted. Your Marketplace submission passes review on scope hygiene.
Do you handle post-launch support?
Yes — patch versions, feature releases, customer support runbooks, and migration scripts when Zoho updates an API version or deprecates a feature.
