SaaSiter – help your software

Best tools and components for SaaS projects — from authentication and billing to analytics and seamless third-party integrations.

Building a SaaS product means assembling the right stack of services quickly and reliably. We help teams select, integrate, and maintain the essential components that every SaaS application needs — so you can focus on your core product instead of reinventing common infrastructure. From subscription billing and SSO to usage analytics and support tooling, we bring proven patterns and hands-on integration expertise to accelerate your time to market.

What We Offer

Authentication & SSO

Integrate secure login flows, multi-factor authentication, and single sign-on using OAuth2, SAML, or OpenID Connect — including social and enterprise identity providers.

Billing & Subscription Management

End-to-end recurring billing, trial management, plan upgrades, proration, and invoicing. We connect your product to payment processors and subscription platforms without the edge-case headaches.

Multi-Tenancy Architecture

Design and implement tenant isolation strategies — shared schema, separate schema, or separate database — with row-level security, scoped APIs, and tenant-aware audit logging.

Analytics & Usage Reporting

Embed product analytics, funnel tracking, and customer health dashboards. We instrument your app and wire up the pipelines that feed your growth and support teams with actionable data.

Third-Party API Integrations

CRM, marketing automation, support platforms, communication services — we build reliable, maintainable integrations with retries, webhooks, and proper error handling built in from the start.

Onboarding & User Lifecycle

Automated onboarding flows, in-app guidance, transactional email sequences, and churn-prevention triggers. We help you convert trials and retain customers with the right touchpoints at the right time.
