Building an Enterprise SaaS Portal

What Is SnapIt SaaS?

SnapIt SaaS is the enterprise portal for the SnapIt ecosystem. It provides multi-tenant architecture so organizations get isolated environments, subscription management powered by Stripe for flexible billing, and team collaboration tools that let multiple users work together within a single account. It is built for businesses that need more than individual accounts can offer.

Architecture Overview

Multi-tenancy is the core architectural challenge. Every tenant's data must be isolated while sharing the same underlying infrastructure. SnapIt SaaS solves this with tenant-scoped partition keys in DynamoDB, ensuring that every query is scoped to a single organization by default. Cognito manages authentication with custom attributes that tie each user to their tenant.

Stripe (Payment Processing + Webhooks)

Stripe handles all payment processing. Subscription changes, upgrades, cancellations, and invoice generation are managed through Stripe's API, with webhooks triggering Lambda functions that update tenant records in DynamoDB in real time.

Key Features

Multi-Tenant Architecture gives each organization a fully isolated environment. Tenant data is partitioned at the database level so there is no risk of data leaking between organizations. Each tenant can have its own settings, branding, and feature configuration without affecting others on the platform.

Subscription Management supports multiple pricing tiers with per-seat billing. Stripe handles payment collection, invoicing, and failed payment recovery. When a subscription changes, a Stripe webhook fires a Lambda function that updates the tenant's access level in DynamoDB instantly. Administrators can view billing history, download invoices, and manage payment methods from the portal.

Team Collaboration lets organizations invite team members, assign roles, and control permissions. Owners can grant admin, editor, or viewer access to different parts of the platform. Team activity is logged in DynamoDB for audit purposes, and role changes take effect immediately across all SnapIt products the tenant has access to.

Performance

Tenant-scoped DynamoDB queries return in single-digit milliseconds regardless of the total number of tenants on the platform. Stripe webhook processing completes in under 200ms, ensuring subscription changes are reflected immediately. The admin dashboard loads in under one second through CloudFront edge caching. Cognito token-based authentication adds no measurable latency to API calls since validation happens at the gateway layer.
