Product Engineering
SaaS architecture
done right.
Building a SaaS product is different from building custom software for one client. Multi-tenancy, subscription management, usage metering, self-service onboarding, and security isolation are engineering concerns that do not exist in a single-tenant world. GreaterHeight brings SaaS-specific engineering experience from day one.

What we build for SaaS products
Multi-Tenant Architecture
Tenant isolation, data partitioning, and access control designed for security, performance, and regulatory compliance — with clear upgrade paths as tenant count grows.
Subscription & Billing
Stripe and Paystack integration for subscription management, usage-based billing, free trials, plan upgrades, proration, and failed payment recovery.
Self-Service Onboarding
Frictionless sign-up flows, email verification, workspace setup, and guided onboarding — reducing time-to-value for new customers without manual intervention.
Admin & Operations Dashboard
Internal tooling for customer management, usage analytics, support tools, feature flagging, and operational visibility — the infrastructure your own team needs to manage the product.
API-First Design
Public-facing APIs, webhooks, and integration capabilities — making your SaaS product connectable to your customers' workflows and the broader software ecosystem.
SaaS Security Patterns
Role-based access control, audit logging, SSO / SAML integration, data residency options, and security compliance readiness — for SaaS products selling into enterprise and regulated markets.
