SaaS Development Services
Launch your SaaS product faster with enterprise-grade architecture — multi-tenancy, subscription billing, analytics, and white-label support built in from day one.
End-to-End SaaS Product Development
We architect and build SaaS platforms that scale from 10 users to 100,000 — without rewrites. Our SaaS development methodology combines multi-tenant architecture, robust billing infrastructure, and product analytics so your platform is ready for growth the day it launches. Every decision is documented in an Architecture Decision Record before a line of code is written.
End-to-End SaaS Product Development
We architect and build SaaS platforms that scale from 10 users to 100,000 — without rewrites. Our SaaS development methodology combines multi-tenant architecture, robust billing infrastructure, and product analytics so your platform is ready for growth the day it launches. Every decision is documented in an Architecture Decision Record before a line of code is written.
- Multi-tenant architecture: schema-per-tenant or shared schema with row-level security
- Subscription billing with Stripe, Paddle, or Chargebee — metered or seat-based
- Role-based access control (RBAC) with team and organisation hierarchies
- SSO/SAML via Auth0, WorkOS, or Clerk for enterprise customer onboarding
- White-label and custom domain routing with automated SSL certificate provisioning
- Full product analytics stack: Mixpanel, Amplitude, or PostHog wired from day one
Multi-Tenant Architecture That Scales
The tenancy model you choose at launch determines your security posture, upgrade path, and infrastructure cost for years. We evaluate schema-per-tenant, row-level security, and silo models against your compliance requirements, customer size distribution, and growth projections — and document the decision before a line of code is written.
- Schema-per-tenant (PostgreSQL): full isolation, simpler GDPR compliance, higher RDS cost at scale
- Shared schema + RLS: cost-efficient, battle-tested with Supabase and Neon at millions of tenants
- Hybrid model: shared schema below enterprise tier, dedicated schema above — best of both
- Tenant onboarding automation: create tenant, seed schema, configure SMTP in under 2 seconds
- Tenant data export and GDPR right-to-erasure API included as standard from day one
- Cross-tenant analytics warehouse via CDC streaming to Snowflake or BigQuery
Subscription Billing & Revenue Infrastructure
Billing is the most underestimated complexity in any SaaS product. A Stripe integration that handles free trials, proration, mid-cycle upgrades, metered usage, and dunning — correctly, in every edge case — takes weeks to build properly. We ship a billing layer that handles every scenario without manual intervention and exposes MRR, churn, and LTV in your admin dashboard.
- Stripe Billing with plan versioning: new plans never break existing subscriber contracts
- Metered billing: event ingestion API, hourly aggregation job, and Stripe meter reporting
- Free trial with card-on-file or trial-without-card — configurable per plan
- Dunning sequences: smart retry schedule, in-app payment-update prompt, configurable grace period
- Proration engine: upgrades, downgrades, and seat changes calculated to the second
- Revenue dashboard: MRR, ARR, new MRR, expansion MRR, churn MRR, and LTV per cohort
SaaS Technology Stack
We build SaaS platforms on proven, cloud-native stacks that your team can operate without specialist heroics. Every service is containerised, observable, and deployable to any cloud. We match the stack to your team’s long-term hiring plan — not just the fastest path to launch.
- Next.js 14+ App Router frontend — server components reduce client JS bundle by up to 40%
- NestJS (Node.js) or Go for high-throughput APIs; Laravel for rapid CRUD-heavy products
- PostgreSQL with pgvector for AI features; Prisma ORM with typed, reversible migrations
- Redis for cache, BullMQ job queues, and sub-second session lookups
- AWS (ECS Fargate + RDS Aurora) or Vercel + PlanetScale depending on ops maturity
- OpenTelemetry traces, Datadog metrics, and Sentry error monitoring from sprint one
Product Analytics & Growth Engineering
Great SaaS products are built for retention — not just signup. We instrument every activation step, build in-app upgrade flows, and design feature-gate logic that drives plan conversions without annoying free users. The growth loop is an engineering decision made at build time, not a post-launch add-on.
- Activation funnel: define ‘activated’ in code and track first-value-moment with sub-24h latency
- PLG feature gates: LaunchDarkly or Unleash with per-tenant override — zero re-deploy needed
- In-app upgrade nudges at limit walls with contextual Intercom or custom in-app component
- Trial-to-paid email sequences via Customer.io triggered by activation and inactivity events
- Customer health score: DAU/WAU ratio, feature breadth, support ticket velocity combined
- Churn prediction model: gradient-boosted classifier on usage signals, retrained weekly
Security, Compliance & Enterprise Readiness
Enterprise buyers require SOC 2 Type II, SSO, and audit logs before they sign. We build the compliance-ready infrastructure into your SaaS from the beginning — so a security review from a Fortune 500 prospect never becomes a six-month engineering detour.
- SOC 2 Type II-ready controls: audit logs, access reviews, encryption at rest and in transit
- RBAC with least-privilege enforcement: no role can read data outside its tenant boundary
- SAML 2.0 / OIDC SSO via WorkOS or Auth0 Enterprise — new enterprise tenant in under one day
- Full audit trail: every data mutation logged with actor, timestamp, IP, and field-level change delta
- GDPR/CCPA tooling: consent log, data export API, and right-to-erasure with cascade delete
- OWASP Top 10 hardening checklist run on every release; penetration test report available
Software your CFO and CISO both sign off on.
Secure, observable, compliant systems built for org charts that span continents — and audits that don’t.
Platform engineering
Kubernetes, Terraform and GitOps — golden paths for 10–500 engineer orgs.
- GitOps + IaC
- Internal dev platforms
- Cost-aware autoscaling
Security & compliance
SOC 2, ISO 27001, HIPAA — control mappings, evidence and audits.
- SOC 2 + ISO 27001
- Vault + KMS
- Pen-test ready
ERP / CRM integration
SAP, NetSuite, Salesforce, Dynamics — with idempotent contracts and replay.
- Idempotent webhooks
- Dead-letter queues
- Audit trails
Observability
OpenTelemetry across every service — traces, RUM, business KPIs.
- OTel everywhere
- Business KPI dashboards
- SLO + error budgets
Predictable, audit-friendly delivery.
Every engagement follows the same stage cycle — so you always know what is happening, what comes next, and who owns it.

A FinServ rollout consolidated 14 AWS accounts, introduced FinOps guardrails and automated rightsizing — saving $2.1M annually.
The tools we ship with.
Platforms your CISO, CFO and engineers all sign off on.
Enterprise software is judged on three axes at once: it has to be secure enough to pass audit, cheap enough to defend in finance review, and ergonomic enough that engineers actually adopt it. Most platforms optimise one and lose the other two.
Golden paths, not gold-plated rules
We design internal developer platforms with a paved road for the common case — so 80% of services ship without a security or platform consultation. Edge cases get review; the rest get velocity.
Compliance as code
SOC 2, ISO 27001 and HIPAA controls are mapped to Terraform modules, OPA policies and CI checks. Auditors get evidence in a repo — not in a spreadsheet someone updated last quarter.
Cost guardrails by default
FinOps tagging, autoscaling policies and cost-per-tenant dashboards ship with every service. Surprises become impossible by design — not by quarterly fire drill.
Observability that tells a story
OpenTelemetry traces, RUM, business-KPI dashboards and SLO error budgets are wired in from sprint zero. When the CEO asks why revenue dipped at 14:23, you have the answer before the meeting ends.
How we make decisions.
Four non-negotiables that govern every engineering choice we make — from stack selection to incident response.
AI-assisted code review
Every pull request runs static analysis and ML-pattern checks before a human reviewer sees it — so engineers spend their review time on logic, not linting.
Observability first
Structured logs, distributed traces, RUM and alerting are wired in from sprint one. When something breaks at 2 a.m., the on-call has the full picture in seconds — not a blank Datadog screen.
Outcome-tied KPIs
Every sprint is reviewed against the business metric it was meant to move — conversion rate, latency, error budget — not story points or lines of code delivered.
Resilient architecture
Graceful degradation, idempotent retries, dead-letter queues and circuit breakers are default patterns, not afterthoughts. Systems that fail quietly are more dangerous than systems that fail loudly.
Three ways to work with us.
Architecture review, security posture, compliance gap analysis and a prioritised remediation roadmap — in four weeks.
- Architecture + threat modelling
- Compliance gap register
- Prioritised remediation plan
Platform engineering or application build delivered in measured waves — with rollback at every phase and audit evidence throughout.
