SaaS
SaaS development
We build complete SaaS platforms: user accounts, plans and recurring billing, customer area, admin panel and a foundation that scales. We work with founders and companies launching subscription software, from MVP to the first paying version.
Launching a SaaS takes more than coding the main feature. Behind every subscription product there is a layer users barely see: authentication, plans, recurring billing, failed payments, permissions, transactional emails and a dashboard to follow your customer base.
We take care of the whole product. We help define what goes into the MVP, design the experience, build the platform and set up an architecture that handles more customers without a rewrite.
We think in product terms, not just code. Activation, onboarding, usage metrics and the path to your first paying customer are part of the conversation from the start.
Who it is for
- Founders with a subscription software idea who need an MVP to validate it.
- Experts who want to turn a method or service into a recurring digital product.
- Companies that want to offer their own tool to their customers.
- Startups that need product and engineering capacity without hiring in-house.
What we deliver
MVP
A first version with the core feature, ready for real users to test and pay for.
Authentication and accounts
Sign-up, login, password recovery, team invites and access roles.
Plans and recurring billing
Subscriptions, free trials, upgrades, coupons and automatic billing with Stripe.
Customer and admin dashboards
A logged-in area for users and an internal panel to follow customers, revenue and usage.
Multi-tenant data isolation
Each customer’s data kept securely separate within the same platform.
Landing page and onboarding
A sales page and in-app first steps designed to turn visitors into active users.
Decisions that shape a SaaS
Before the first line of code, a few choices change the product’s architecture and cost:
Pricing model
Flat subscription, per seat, usage-based or freemium. The choice changes plan structure and how usage is measured.
Individual or team accounts
Company accounts with teams, invites and permissions work differently from individual accounts. Decide early.
Onboarding
The first minutes decide whether a user comes back. A short path to the first result beats a long feature list.
Metrics from the MVP
Activation, retention and recurring revenue tracked from version one show what to build next.
Integrations
Which tools your customers already use and which ones the product must connect to in order to be adopted.
Security and GDPR
Data isolation between customers, access control and personal data handling from the first release.

Time to launch
How long a SaaS takes depends mostly on the size of the MVP. The leaner the first version, the sooner you have paying customers to learn from.
In the proposal we separate what is essential for launch from what can come later, with a schedule per milestone.
How much does it cost to build a SaaS?
Pricing is based on scope, with a fixed quote before we start. The main drivers are:
- Complexity of the product’s core feature.
- Billing model: plans, free trials, usage-based pricing and coupons.
- Integrations with other tools and APIs.
- User roles, teams and permissions.
- Real-time or AI-powered features.
We recommend launching an MVP and reinvesting from the first revenue instead of building the full product before you have customers.

SaaS development FAQ
What is a SaaS MVP?
It is the smallest version of the product that solves the customer’s core problem and lets you charge for it. It validates the idea with real users before you invest in the full product.
How much does it cost to build a SaaS?
It depends on the MVP scope, the billing model and the integrations. You receive a fixed quote in the proposal before we start.
Do you set up recurring billing?
Yes. We use Stripe for subscriptions, free trials, upgrades and automatic billing.
Will the platform scale?
The architecture is planned for growth from the MVP: a well-modeled database, data isolation between customers and infrastructure that scales. Growing should not require a rewrite.
Do you build the SaaS landing page?
Yes. We build the landing page and onboarding, which are what turn visitors into active users.
Can we add AI features to our SaaS?
Yes. We integrate language models for features such as assistants, document analysis, summaries and in-product automation.
Who handles hosting and infrastructure?
We set up the cloud infrastructure with database, backups and monitoring. Hosting costs belong to the product, and we estimate them in the proposal.
Can I start without an in-house tech team?
Yes. We cover product, design and engineering. It is common to start this way and build an internal team once the product gains traction.
