SaaS Development

With a SaaS product, three decisions get made early and are expensive to reverse later: how your customers’ data is kept apart, who handles the billing, and where the data lives. We start with an MVP that carries one workflow end to end – and make those three decisions so they still hold as you grow.

Sound familiar?

  • You have a product idea but no technical team to build it.
  • You want to reach the market fast instead of developing in the dark for months.
  • Your existing solution is growing and now needs subscription billing, multi-tenancy and an architecture that holds up.

Then a conversation is the fastest route to an assessment.

What we do - What we build for you with SaaS & MVP

  • MVP development

    The first lean version of your product – focused on the essentials so you get real feedback quickly.

  • Multi-tenant platforms

    One application, many customers – with cleanly separated data and per-tenant configuration.

  • Subscriptions and billing

    Recurring payments, plans and invoices, cleanly connected to Stripe or another provider.

  • Scaling

    When your first users turn into many: an architecture that grows with you instead of holding you back.

Start small, then grow

Most product ideas do not fail because of technology – they fail because they are built past the market for too long. That is why we start with an MVP: the smallest version that delivers real value and tells you whether you are on the right track. In practice that means one use case, one type of user, one way to pay – everything else waits until paying users ask for it.

From that foundation we build step by step – on a Laravel architecture designed from day one for growth, multi-tenancy and recurring billing.

Three decisions get made early and are expensive to reverse later. First, tenant separation: a shared database with a tenant column is cheap and enough for most products, while a database per customer costs more to operate but is often required for sensitive data and enterprise buyers. Second, billing: Stripe Billing handles plans, proration, tax and dunning for you – rolling your own billing logic almost always costs more than expected. Third, data protection: if you sell into the EU, hosting location, data processing agreements and a deletion concept belong in the plan from the start, not in the first enterprise deal.

What we will not do is sell you a year of development before anyone has paid for the product. If the market does not confirm the idea, an MVP you stop is the cheapest possible outcome.

When we advise against it

Not every enquiry belongs with us. These are the ones we turn down in the intro call – here they are upfront, so you can skip the call.

  • The full build before the first paying user

    We build the MVP first. If the market does not confirm the idea, an MVP you stop is the cheapest possible outcome.

  • An application for exactly one company – yours

    That is custom software and needs neither multi-tenancy nor subscription billing.

    Better fit: Custom Software
  • Your own billing logic instead of a provider like Stripe Billing

    By the time you hit cancellations, credit notes and VAT it costs more than the provider ever would have.

What the price depends on

We bill custom projects transparently by the hour. After a free intro call you get an honest estimate from us here in Bavaria – so you know where you stand before anything starts.

Verifiable

Instead of references: what you can check yourself

For this service we have no client reference we could show with numbers we can back up – and inventing one is off the table. What we can offer instead is work of ours that is public and that you can check without us being involved.

  • This website

    Built with React 19 and Next.js 16, statically pre-rendered. The source, the sitemap, the structured data and the Core Web Vitals are all public – run the homepage through PageSpeed Insights and you see the same numbers we do.

  • Our Shopware plugins

    Published in the official Shopware Store, which means they went through Shopware’s code review. The description, changelog and ratings live there, not here.

  • Our iOS app

    WebDAV Browser is on the App Store – published under our developer account and through Apple’s review.

Who builds this?

You work directly with Marcel

At Viovenia your project is not passed between rotating teams – it is built directly by Marcel, senior software engineer. You talk to the person who writes your code, from the first call to running in production. No project-manager loop, no ticket ping-pong.

How we work - Five steps to your project

Transparent and free of stress – that is how working with us goes. More about our process.

  1. 01

    Intro call

    Half an hour where you describe the project and get concrete questions back. It ends with a first read on feasibility and rough size – including when that read is “not worth it”.

  2. 02

    Concept & quote

    In writing, with scope, the technology involved, the assumptions behind it and what is explicitly not included. Split into “needed at launch” and “can come later”, so the scope stays negotiable.

  3. 03

    Development in stages

    After each stage there is something usable on a test environment, not just a status report. Change requests go in where they are cheapest: before the next stage starts.

  4. 04

    Launch

    Before going live: a run through the core workflows, a backup concept, monitoring switched on. Afterwards you get access, source code and documentation handed over in full, not on request.

  5. 05

    Operation

    Updates, monitoring and further development – as fixed care or on call. No minimum term: what keeps you should be the work, not the contract.

Frequently asked - Questions about SaaS & MVP

What is an MVP?
A minimum viable product is the smallest sensible version of your product. It contains exactly the features needed to give real users value and to collect feedback – without burning budget on features nobody asked for.
What does building a SaaS platform cost?
An MVP can often be built in the low five figures, mature platforms cost more. We recommend starting small and investing deliberately based on real user feedback.
What does multi-tenant mean?
Multi-tenancy means one single application serves many customers while keeping their data cleanly separated. It is the foundation of almost every SaaS product. The usual approach is a shared database with a tenant identifier on every record – cheap to run and right for most products. A separate database per customer costs more effort but is often necessary for sensitive data or enterprise requirements.
How long until the first usable release?
For a properly scoped MVP – one use case, one type of user, one way to pay – plan on eight to fourteen weeks of development. Add multi-tenancy and subscription billing from the start and it becomes more like twelve to twenty. Those windows start once the scope is locked. What blows up timelines in practice is rarely the development itself, it is scope added later and long feedback loops.
How do I bill subscriptions without building it all myself?
Through a provider like Stripe Billing. It handles plans, proration on plan changes, tax rates, failed payments and dunning. Custom billing logic looks simpler at the start and gets expensive at the latest when refunds, credit notes and VAT show up.
Do I own the code?
Yes. You get the complete, documented source code and the infrastructure configuration. There is no lock-in with us: if you later want to continue in-house or with another team, we hand over cleanly.
