Custom Software Development & SaaS Development
Custom software development without agency overhead: one maker who designs, builds and ships your application. Web apps from €7,500, full SaaS products from €18,000 — one fixed price up front, with the source code in your own Git. Four SaaS products I built myself are live today.
Custom software development: what I build
Off-the-shelf software forces your business into the vendor's mould; custom software follows your process. Whether you need a client portal, a quoting or planning tool, or a complete SaaS product with accounts and subscriptions, I design and build it as a single dedicated maker — from first sketch to go-live.
- Custom web app — from €7,500, one-off. A focused application for your team or your customers: a portal, dashboard or internal tool.
- Custom SaaS — from €18,000, one-off. A full product with user accounts, roles and subscriptions, ready to sell to your customers.
- SaaS management — from €149 per month, cancellable monthly. Ongoing technical management of your product once it is live.
SaaS development you can verify: four live products
Don't judge SaaS development by a sales pitch — judge it by working software. I designed, built and launched these four products myself, and you can look at them today:
- Voxori — AI phone receptionist as a SaaS, from €99 per month;
- WeldProof — weld inspection SaaS (ISO 3834);
- Koldwerk — refrigeration SaaS (F-gas, BRL 100);
- Kozynofferte — quoting SaaS for window frames, from €49 per month.
Seven projects are live in total, including websites and web apps — you will find them all in the portfolio.
What custom software costs
You get one fixed price before I write a single line of code. No hourly billing, no surprises afterwards: the scope is written down in the proposal, so you know exactly what will be delivered and what it costs.
- Custom web app: from €7,500;
- Custom SaaS: from €18,000;
- SaaS management: from €149 per month, cancellable monthly.
Your code, your property — no vendor lock-in
With many agencies, the source code of your application stays with the agency; if you leave, you start over. Not here. The source code lives in your own Git environment, and after full payment you own 100% of the design, code, content and domain. Any developer can pick it up later — you are not tied to anyone, including me.
Process & payment: see it before you commit
Every project starts free of charge and without obligation: an audit of your current situation, a mockup and a proposal with a fixed price and schedule. Building only starts — and payment is only due — after your written approval.
- 50% on approval of the proposal, 50% on delivery, before go-live;
- Payment term of 14 days — bank transfer, iDEAL or SEPA;
- Average delivery time of 4–6 weeks; for larger SaaS projects the schedule is fixed up front in the proposal;
- 6 months of aftercare included; performance-first with Lighthouse 90+ as the target; interface available in 5 languages if you wish.
The full route, step by step, is on the process page.
