PHP Architecture for SaaS Platforms
Tenant management, subscription billing and core product belong in separate Bounded Contexts. Jardis gives your SaaS platform the architecture that enforces tenant isolation at the code level, from the first context to enterprise scale.
The More Tenants You Have, the Riskier Every Deployment Gets.
Laravel monoliths start fast. But without domain boundaries, data leaks between tenants, billing logic sprawls, and feature flags become maintenance hell.
Tenant isolation exists only on paper
Tenant data is separated by WHERE clauses. One missing scope, one forgotten filter, and customer data leaks across tenants. The more tenants you have, the higher the risk. A single missing tenant scope in a query is enough for a data breach.
Billing logic scattered across the codebase
Subscription status, plan limits and billing rules live in controllers, middlewares and views. A pricing change requires edits in dozens of files. Switching from flat-rate to usage-based billing turns into a quarter-long project instead of a sprint.
Feature flags as nested if/else hell
Every plan has different features. The logic ends up as nested conditionals everywhere. Introducing a new plan or offering an enterprise tier with custom limits means weeks of changes spread across the entire codebase.
Tenant boundaries in code, not in WHERE clauses.
The Jardis Builder generates physical domain boundaries for every SaaS domain. Tenant, Billing and Core Product as standalone packages with enforced separation.
Tenant Management as Its Own Bounded Context
Tenant logic becomes a standalone package with its own repository pipeline. No accidental access to foreign tenant data because separation is enforced at the filesystem level. Whether shared database with row-level isolation or database-per-tenant: the domain logic stays identical, only the repository adapter changes.
Billing, Onboarding and Core Product decoupled
Each domain gets its own commands, queries and events. SubscriptionCreated, PlanUpgraded, TrialExpired, UsageLimitReached: the builder generates the event structure as typed PHP classes. Billing does not know about the core product. Switching from flat-rate to usage-based billing only affects the billing context, not the product.
SaaS Architecture in PHP, ready to ship
The builder generates tenant-aware PHP infrastructure: every Bounded Context gets an isolated repository pipeline with tenant scoping. No global state, no forgotten WHERE clauses. Your team writes the business logic: tenant provisioning, usage metering, plan rules and trial-to-paid conversion.

What SaaS Teams Gain with Jardis.
From MVP to multi-tenant platform. Jardis grows with your product.
Bounded Contexts per Domain, Not per Tenant
Tenant management, billing, core product: each domain is a standalone package. Tenant data stays isolated by architecture, not by WHERE clauses someone can forget. Even at 1000 tenants, isolation remains structurally guaranteed.
Billing Context in Minutes Instead of Sprints
Subscription management, usage metering, trial conversion or plan upgrades as their own domain? Define the schema, start the builder. Commands, events and repository pipeline are ready before the first ticket is closed.
Teams Own Domains, Not Features
One team owns billing. Another owns the core product context. Deployments are independent. The billing team iterates on pricing models without the product team having to coordinate a release.

Answers to the most important questions about Jardis in the SaaS context.
Jardis generates Tenant Management as its own Bounded Context with a dedicated repository pipeline. Tenant isolation is enforced at the filesystem level, not through WHERE clauses that can be forgotten. The tenant context communicates with other domains exclusively through domain events. A TenantProvisioned event triggers initialization in billing and core product.
