What is a multi-tenant CRM?
A multi-tenant CRM is one CRM platform serving many separate businesses, called tenants, each with its own contacts, deals, tickets, users and settings, on shared infrastructure. Each tenant sees only its own data. It is how SaaS CRM products are built, and how groups run one CRM across several companies.
How do you keep tenants' CRM data separate?
Most platforms put a tenant identifier on every record and enforce it in code for every query, background job, cache and file, failing closed if the tenant is missing. Large or regulated tenants can get their own schema or database. Isolation needs its own tests, separate from permission tests.
Should we build a custom CRM or use Salesforce or HubSpot?
Use an established CRM if it fits how you sell and support. Choose custom CRM development when the CRM is your product, when you need tenants the big platforms cannot model, when per-seat costs outgrow a build, or when your workflows depend on rules those platforms cannot express.
How does CRM data migration work?
Map the old records to the new model, then move them with migrators that can be re-run safely. Reconcile legacy identifiers and report records that need a human decision before import. Migrate in phases, check each phase against the source, and keep the old system available until the new one is signed off.
What does SaaS CRM development add to a normal CRM?
SaaS CRM development adds the layer that lets you sell the CRM: tenant sign-up and onboarding, plans and billing, feature gating by plan, an operator console across tenants, and isolation strong enough to promise customers their data is safe. It also adds audit trails, so you can show who did what.
Which CRM has Muzammil built?
Omnitech CRM, a ground-up multi-tenant CRM and revenue platform covering companies, contacts, leads, deals, activities, tickets and custom fields. It has fail-closed tenant isolation, 126 permissions across 22 modules, and transactional migration tooling to replace a legacy Perfex CRM installation. I am its CTO.
What does Muzammil charge for CRM development?
A two-week Product Blueprint Sprint is $3,900. A Platform & Integration Review of an existing CRM is from $5,900, or $8,900 with a detailed migration plan. Building runs at $4,800 a month for 80 hours, or $75 an hour ad hoc. A 60-minute Decision Diagnostic is $300.
Can you migrate us off Perfex CRM?
Yes. Omnitech CRM was built to replace a long-running Perfex installation, with migration tooling that maps Perfex records and roles, reconciles legacy identifiers and reports records needing a decision before import. A Perfex CRM migration starts with a review of your data and customisations, then a phased plan.
Which technologies do you use for CRM platforms?
Omnitech CRM runs on Laravel 13, Livewire 4 and Filament 5, with Redis for queues and real-time features. I also build with Node.js, Next.js and Python, and deploy on AWS. The stack follows your team and existing systems.
Do you stay after the CRM launches?
Yes, if you want me to. A monthly fractional CTO plan from $1,500 for 20 hours keeps me reviewing new modules, tenants, roles and integrations against the isolation and permission model. Or your team takes over with the documentation and tests, and I stay available for reviews.
