Your SaaS idea becomes a product you can actually sell

SaaS development

I build the whole product, from the first screen to recurring billing, with an architecture that holds up once customers start coming in.

What building a real SaaS involves

A SaaS is not a website with a login. It is a product that charges on its own, keeps each customer’s data apart and does not fall over the day a hundred of them show up at once. This is what I build to get it there.

The product

  • Customer dashboard and admin panel
  • Signup, login, roles and per-team permissions
  • Data isolation between customers from day one
  • Onboarding that gets users working without asking you for help

The billing

  • Plans, trial periods and usage limits
  • Subscriptions and recurring billing with Stripe
  • Signups, cancellations and plan changes with no manual work
  • Automatic invoices and failed-payment notices

What holds it all up

  • Architecture built to grow without a rewrite
  • Cloud deployment with separate environments
  • Usage metrics to know what works and what is dead weight
  • Alerts and error logging so you find out before a customer does

Why build your SaaS with me?

A product you can sell, not a demo that impresses

Most SaaS products that die do not die from lack of customers. They die because the product could not take the growth, or because charging was still manual work. I build for that moment, not for next week’s demo.

  • You charge from the first customer

    Subscriptions, plans and invoices are in from the start. Not something bolted on later when it already hurts.

  • It holds up when people arrive

    The architecture is decided with a hundred customers in mind, not the first one. Growing does not force a rewrite.

  • Each customer’s data, kept apart

    Isolation between customers is designed up front. Adding it afterwards is one of the most expensive fixes there is.

  • The product is yours

    Source code, infrastructure and accounts in your name. If one day we go separate ways, the SaaS keeps running.

What kind of SaaS do I build?

Subscription products for businesses, built on top of a process someone is already doing by hand.

Vertical tools

Software for one specific industry, where generic products never quite fit.

Data dashboards

Products that pull information from several sources and turn it into decisions for the customer.

Marketplaces and platforms

Two sides that need to meet, with payments, commissions and reputation in between.

Customer portals

Turning a service you already provide into a product with its own access and a monthly fee.

Paid APIs

Selling your data or your process as an API, with keys, usage limits and pay-per-use billing.

Products with AI inside

Language model features built into the product, with cost control per customer.

Tell me about your SaaS idea

How I go from your idea to a SaaS that charges

01

We define the product

What it solves, who for, and what can be left out of the first version without breaking the pitch.

02

I design the architecture

How customers are kept apart, how billing works and which decisions have to be made now so you do not pay for them in a year.

03

I build in versions

Frequent deliveries you can try and show. First what lets you sell, then what makes it comfortable.

04

I launch and evolve it

Deployment, metrics and alerts in production. From there the product grows on what real users tell you.

Common questions

Frequently asked questions about SaaS development

What people almost always ask me before starting a subscription product.

  • How much does it cost to build a SaaS?

    It depends on how much product you need before you can charge. A scoped first version sits in a very different range than a platform with several roles and integrations. On the first call I give you a range and the variables that move it, so you decide with numbers and not with a feeling.

  • How long until it is in production?

    A first version that already lets you charge usually takes two to three months. The timeline is set mostly by how much gets left out, and we have that conversation before starting, not halfway through.

  • What goes into the first version?

    The minimum for someone to use it and pay you. Everything else goes on a list and comes later, once users say what is actually missing.

    • Signup, login and account management.
    • The feature that justifies someone paying.
    • Plans and recurring billing working.
    • An admin panel so you can operate without asking me for anything.
  • What do you use to charge subscriptions?

    Usually Stripe, which covers plans, trials, plan changes, failed payments and invoices. If your case calls for another gateway, I integrate that instead. What matters is that billing does not depend on someone checking anything every month.

  • Can I start with an MVP and grow later?

    That is what I recommend almost every time. We build the version that lets you validate and charge, and the product grows from what users ask for. What matters is that the first version does not force you to throw it all away once it works.

  • Who owns the code and the infrastructure?

    You do. The repository, the servers and the service accounts are in your company’s name from day one. No hidden dependencies, no vendor lock-in.

  • Do you handle maintenance afterwards?

    Yes, if you want. I can run maintenance and evolution on a monthly fee, or leave the project documented for your team to continue. You decide, and it can change along the way.

  • What about server and service costs?

    They sit outside the development cost and I tell you about them up front. A small SaaS starts with low infrastructure costs and grows with usage, so the bill normally goes up once you are already charging.
