SaaS Development Services

Everything you need to build, launch, and scale a SaaS product

Multi-Tenant Architecture

We design the right multi-tenancy architecture for your scale: shared database with row-level security, schema per tenant, or database per tenant. Data isolation, predictable performance, and scalability without future rewrites.

Billing and Subscription Management

Integration with Stripe Billing, Paddle, or similar. Plans, trial periods, upgrades/downgrades, recurring billing, failed payment handling, and SaaS metrics (MRR, churn, LTV). The financial engine of your product, automated.

Onboarding and Product Experience

Registration flows, initial setup, guided tours, and user activation designed to maximize trial-to-paid conversion. Every step optimized with data to reduce time-to-value for your users.

API and Integration Ecosystem

Documented REST or GraphQL API for your customers and integrators to connect their systems. Webhooks, OAuth 2.0, rate limiting, and API versioning. An integration ecosystem that turns your SaaS into a platform.

Frequently Asked Questions About SaaS Software Development

Do you have experience building SaaS products?

Yes. We have worked with companies like Mozrest (a SaaS reservation management platform operating across multiple European countries) and Billin (electronic invoicing SaaS). We understand the specific challenges of the SaaS model: multi-tenancy, plan and subscription management, automated onboarding, product metrics, and on-demand scalability.

What multi-tenancy model do you recommend for a SaaS?

It depends on your scale, isolation requirements, and budget. The main options are: shared database with row-level security (most cost-effective, ideal for startups), schema per tenant (good balance between isolation and cost), or database per tenant (maximum isolation, for enterprise). We evaluate your specific case and recommend the option that best balances cost, performance, and security.

How much does it cost to build a SaaS platform?

A functional SaaS MVP typically starts from EUR 20,000-40,000, including basic multi-tenancy, authentication system, admin panel, and an onboarding flow. More mature platforms with automated billing, integrations, public API, and multi-region support can range from EUR 50,000 to EUR 120,000. We offer a free audit to give you an estimate tailored to your case.

Can you migrate our existing SaaS to a more scalable architecture?

Yes, this is a scenario we see frequently. Many SaaS products start as a monolith and need to migrate to an architecture that supports scale as they grow. We perform a technical audit of the current system, identify bottlenecks, and design a phased migration plan that allows you to keep operating while refactoring. No big bangs, no extended downtime.

How do you handle billing and subscriptions in a SaaS?

We integrate with billing platforms like Stripe Billing or Paddle to manage plans, subscriptions, upgrades, downgrades, trial periods, and recurring billing. We implement robust webhooks, failed payment handling (dunning), and SaaS metrics dashboards (MRR, churn, LTV). We do not reinvent the wheel: we use what works and integrate it with your system.
