SaaS Product Development

Who this is for

SaaS development is right for founders and product teams who need to build software that serves multiple customers independently, each with their own data, settings, and users. This is more complex than a regular web app; the early architectural decisions determine whether you can scale or not.

You have a product idea but no technical co-founder to architect and build it
Your current prototype or MVP wasn't built for real multi-tenancy
You need billing, subscriptions, and usage tracking but haven't built it properly yet
A competitor has launched and you need to ship faster without cutting corners in the foundation
Your existing SaaS has grown and the original architecture no longer holds

What we deliver

A production-ready SaaS platform with all the infrastructure layers that early-stage teams typically skip, and then struggle with later.

Multi-tenant architecture

Each customer gets their own isolated data environment. We design the tenancy model upfront: shared schema, separate schema, or separate database, based on your compliance and scale requirements.

Tenant isolation by design
Per-tenant configuration and branding
Data segregation and access controls
Tenant onboarding and provisioning

Auth and user management

Secure, extensible identity layer with roles, permissions, and team management built in from the start.

Email/password and SSO (SAML, OAuth)
Role-based access control (RBAC)
Team and organization management
Audit logs and session management

Billing and subscriptions

Subscription logic, usage metering, and payment processing integrated cleanly, not bolted on after the fact.

Stripe or Paddle integration
Subscription tiers and plan changes
Usage-based billing
Invoice generation and dunning

Admin panel and ops tools

Internal dashboards for your team to manage customers, debug issues, and operate the product without touching the database directly.

Customer management and impersonation
Feature flags and rollout controls
Metrics and revenue reporting
Support tooling

How it works

SaaS products require more upfront design than other software. Skipping this step is how you end up with a product that works at 10 customers and falls apart at 100.

Product spec and user flows (2–3 weeks). We document the product in writing: user roles, key flows, data model, and feature scope for the initial version. This becomes the reference for all build decisions.
Architecture design (2–4 weeks). We design the tenancy model, auth strategy, API structure, and deployment architecture. You approve before any code is written.
Core platform build (10–24 weeks). Built in milestones. Each milestone delivers working, testable software. You review and provide written feedback. No surprise pivots.
Billing and integrations layer. Payment processing, external API integrations, and webhooks, added as a defined milestone (not as an afterthought).
Launch preparation. Load testing, security review, monitoring setup, and documentation. Your team can operate the system from day one.
Post-launch iteration (optional). Ongoing retainer for features, fixes, and platform improvements based on user feedback.

Indicative pricing

SaaS is not a simple project. The ranges below reflect real-world engineering effort, not the optimistic quote you'll get from an agency that hasn't thought it through.

MVP SaaS platform

€80,000–€250,000+

What it covers: Multi-tenant foundation, auth with basic RBAC, core product feature set, billing integration, and an admin panel. Enough to acquire and serve real paying customers.

Not included: Mobile apps, complex third-party integrations, compliance certifications (SOC 2, ISO 27001).

Full-featured SaaS product

€250,000–€800,000+

What it covers: Everything in the MVP tier plus advanced user roles, SSO, deep integrations, usage-based billing, a robust ops toolset, and a public API for third-party developers.

Best for: Founders going from validated idea to full launch, or teams replacing a legacy platform with a properly engineered one.

Post-launch retainer

Quoted on scope

What it covers: Ongoing feature development, performance work, security patches, and platform scaling as your customer base grows. Scope and cadence defined in a monthly brief.

Best for: Teams that want a consistent engineering partner after launch rather than rebuilding context every time.

Ranges are indicative. Final fees depend on scope defined in discovery. We don't quote from a one-page brief; discovery is always the first step for projects of €100K+.
