Auth, billing, multi-tenancy, onboarding, usage limits — the solved problems that still take significant time to implement correctly. We have built these systems before.
We scope around the system you actually need to operate, maintain, and operate — not a fixed vendor product or a one-size-fits-all implementation.
Data isolation, tenant configuration, and access control designed for B2B requirements from day one — not retrofitted later.
Email, social, and SAML SSO with MFA — built on proven libraries, not custom cryptography. Enterprise SSO documented for your customers.
Stripe integration with plan management, usage-based billing, webhook idempotency, dunning, and revenue recognition data.
Internal dashboards for tenant management, feature flags, support tooling, and operational visibility — essential before launch.
Activation-optimised onboarding — guided setup, empty states, and progressive feature disclosure, with analytics to track activation.
Each engagement is broken into defined phases with reviewable outputs. Scope can adapt, but accountability stays visible.
Map core user flows, define the data model, and agree on the initial feature set before any code is written.
Auth (including SAML SSO), multi-tenancy, and core data model — the infrastructure every feature depends on.
Iterative delivery of product features with staging environment reviews at each milestone. No feature shipped without tests.
Stripe integration with plan management, usage-based billing, webhook idempotency, dunning, and tax handling.
Internal dashboard for tenant management, feature flags, support tooling, and operational visibility — essential before launch.
Technology choices follow your environment, operating constraints, team capability, and long-term ownership requirements.
The same technical capability can require very different controls, integrations, and operating models across industries.
Developer tools, productivity platforms, API-first products, internal tooling SaaS.
Fintech products, expense management, accounting SaaS, compliance tools.
Practice management, billing SaaS, patient engagement, clinical workflow tools.
LMS platforms, assessment tools, institution management, tutoring SaaS.
The exact architecture and delivery plan depend on your environment. These answers describe how OSYSTIC approaches the work.
We implement row-level security in PostgreSQL. The choice between separate schema and tenant_id approach is made during architecture scoping based on your scale and isolation requirements.
Yes. We implement it using WorkOS, Auth0, or custom libraries, and document the configuration process for your enterprise customers.
Yes. Stripe webhooks require idempotency handling and retry management. We implement this correctly from the start — webhook events are processed exactly once regardless of retries.
All code, infrastructure documentation, runbooks, environment variable inventory, and operational playbooks. Your team can operate and extend the product from day one without us.
