SaaS web applications

What it is

A subscription product built to be operated: organisations, roles, usage, billing and the release pipeline that keeps it running after launch.

Why businesses need it

SaaS is not a website with a login. Tenancy, billing and permissions are where most first versions quietly fail — and where a rebuild costs the most.

What MIWEBX delivers

• Product discovery, scope and MVP definition
• Multi-tenant architecture with organisation and role models
• Subscription billing, plans, trials and usage limits
• Onboarding, invitations and self-serve setup
• Admin console, support tooling and audit trails

Core features

• Row-level tenancy so one customer can never read another's data
• Plan and feature gating driven from configuration, not code edits
• Metered usage with limits, overages and alerts
• Background jobs, retries and idempotent writes
• Session, API-key and role-based access control
• Product analytics events emitted from the first release

Technical capabilities

• Tenant identity resolved in middleware and carried into every query, not inferred from the browser
• Billing provider events stored as a log, so a replayed or missed webhook converges on the right state
• Migrations run as part of deploy and stay backward-compatible so a rollback costs no data
• Capability checks for plan and feature gates written in one place, read per request
• Usage metered from the events that create it, so the meter and the limit share a definition
• Queue workers with idempotency keys so a retry cannot duplicate a record
• Separate credential and data paths for staging and production organisations

How we build it

• Cut the scope to the flows that prove the product, written as a definition document
• Design the tenancy, role and billing data model before the first screen is built
• Build the user-facing product and its admin console against that same schema
• Wire billing, email and analytics, then test the failures: declined card, downgrade, cancellation
• Deploy staging and production, seed the first organisation, and release through the pipeline
• Review audit, error and usage telemetry after launch and fix what the data shows

Technology stack

• React
• Next.js
• TypeScript
• Node.js
• PostgreSQL
• Prisma
• Stripe

What you receive

• A deployed product with staging and production environments
• Database schema, migrations and seed data in your repository
• Billing configuration and plan definitions you can change
• Admin and support tooling with audit history
• Architecture notes: what is a decision, what is a shortcut

Business benefits

• Launch with billing and permissions already correct
• New plans without a code release
• Support staff can solve problems without engineering
• Investors see a product, not a prototype
