SaaS Platform Engineering

Scalable Multi-Tenant Architectures & Automated Billing Solutions

Inviro360 is a custom software studio specializing in SaaS product development. Building a successful Software-as-a-Service (SaaS) application requires more than just a functional client interface; it demands a highly secure user authentication system, an optimized multi-tenant database structure, automated subscription billing engines, and an operational admin dashboard to manage tenants and monitor system usage.

Our engineering team helps founders and enterprises design, build, and launch robust SaaS products. We focus on scalability, data isolation, and API security to ensure your platform runs reliably as you onboard thousands of active organizations.

What We Do in SaaS Development

1. Multi-Tenant Database Architecture We design secure database tenancy structures. Depending on your data security and scale requirements, we implement logical tenant isolation (shared database with tenant filters) or schema-level isolation.

2. Stripe Billing & Subscription Engines We integrate advanced billing engines (like Stripe Billing or Chargebee) to manage subscription tiers, metered billing, upgrade/downgrade calculations, discount coupons, and automated payment recovery (dunning).

3. User Authentication & Role-Based Access We implement secure sign-up flows featuring Single Sign-On (SSO/OAuth), Multi-Factor Authentication (MFA), password encryption, and granular Role-Based Access Controls (RBAC) to manage team permissions.

4. Admin Management Dashboards We build custom admin consoles that allow your operations team to monitor tenant health, manage billing plans, track server resources, review system logs, and handle support requests.

Our SaaS Engineering Process

Phase 1: Tenancy Model & Billing Mapping We audit your scalability and regulatory requirements to select the correct logical tenancy model. We define your subscription plans, pricing structures, and refund rules.

Phase 2: Database Schema & API Design We design clean database tables with optimized indexes. We write API definitions to ensure fast data exchange between the client dashboard and the backend server.

Phase 3: Core Workspace & Feature Building We build the primary workspace interface, document upload systems, automated notification feeds, and third-party integrations (like email servers or CRM connections).

Phase 4: CI/CD Setup & Cloud Deployment We package the application using Docker, configure automated testing pipelines, set up error monitoring (Sentry), and deploy to auto-scaling cloud servers (AWS/GCP).

Technologies We Use

• Backend & APIs:** Node.js (NestJS), PostgreSQL, Redis, GraphQL
• Subscription Engines:** Stripe Billing API, Chargebee, PayPal Webhooks
• Authentication:** Auth0, Firebase Auth, JWT, OAuth 2.0
• Infrastructure:** Docker, AWS ECS/Fargate, Terraform, Kubernetes

Frequently Asked Questions

How do you prevent one tenant from accessing another's data? We enforce database-level access rules and query middleware filters. Every database request is audited against the active session's tenant ID, guaranteeing strict data isolation.

Can we support custom domain mapping for our tenants? Yes. We set up dynamic SSL certificate provisioning and router rules so your enterprise tenants can map their white-label custom domains (e.g. app.tenantname.com) directly to your SaaS platform.

What is the timeline for a SaaS MVP? A standard SaaS MVP containing user authentication, tenant accounts, Stripe billing integration, and core workflow features takes between 8 to 12 weeks to build.
