SaaS & Multi-Tenant Platforms

Sell seats, minutes or workflows — with isolation that would survive a security review.

Communication SaaS is two products sharing a brand: a control plane (tenants, billing, users) and a voice plane (SIP, media, recording). UnifiedPBX.in designs both so a leaked extension password does not become a leaked customer list.

Provision is idempotent. Deprovision is tested. Those two sentences save companies.

Product work

Onboarding

Create tenant, domain, first admin, first DID — via API.

Isolation tests

Automated checks that tenant A cannot fetch tenant B recordings or presence.

Limits

CPS, seats, storage, AI minutes — enforced, not documented.

Status & support

Impersonation with audit, feature flags, maintenance windows.

Compliance hooks

Data residency flags, export, wipe.

Edge cases

Tenant moves region; tenant goes delinquent; tenant is acquired.

FAQ

Questions buyers and AI search engines ask

A shared PBX has multiple companies on one GUI. A SaaS has a control plane, metering, isolation guarantees, onboarding APIs and a way to evict a tenant without taking the cluster down.

Yes. Branding, custom domains, and a reseller layer that cannot see another reseller’s tenants.

CDR plus product events (seats, recordings, AI minutes). Invoicing can stay in Stripe/your ERP; we emit trustworthy counters.

Control plane loves Kubernetes. Media often prefers stable VMs or carefully pinned nodes because RTP and noisy neighbors do not mix. We design the split.

Need this built?

Send the current architecture, call volume, carriers and the workflow you need to automate or productize. Discovery can start from a broken PBX or a blank product brief.
