forms the domain or execution core of the solution.
Specialist niche
Subscription billing and plan logic
Model subscriptions, quotas, upgrades, cancellations and invoice status consistently. General Informatics covers analysis, target architecture, implementation, integration, quality assurance and production-oriented operations from one accountable partner.
Architecture and stack
The most common technology chain for Subscription billing and plan logic
Technology is selected according to the problem, operating model and existing landscape—not fashion. The following chain is a frequent and sensible starting point.
Mollie →Stripe →PayPal →PostgreSQL →Webhooks →Docker
Stripe
provides persistent data, state or integration information reliably.
PayPal
connects components with the wider system landscape through typed, testable contracts.
PostgreSQL
isolates runtime and dependencies for reproducible deployments.
Webhooks
handles caching, asynchronous processing or horizontal decoupling.
Docker
makes releases, observability and secure operation repeatable.
Architecture decisions
- Build versus buy and provider dependencies
- Synchronous request versus asynchronous job
- Tenant separation and data isolation
- Error handling, retries and idempotency
- Scaling, cost and performance budget
- Observability, audit and recovery
Technical quality goals
Clear interfaces, limited coupling, traceable data flows, reproducible environments, automated tests and a documented recovery path. Lighthouse-sensitive frontends use lean assets, server-side metadata and controlled third-party scripts.
