To build or take over an app, three steps: scoping, build, care. To steer the tech of your company, a fractional CTO. To automate a repetitive task, a fixed price given after the call. All prices exclude VAT, and you know the fixed price before you commit. I am a senior, with 20 years in the trade: I build and I verify. About me
First
An idea, a need, or an app to take over. You want a clear plan before you commit.
€1,900excl. VAT · one week
For an app to take over: the assessment
Then
Your web or mobile app, built and put into production.
€11,900excl. VAT · per month
What for: Business software · Mobile app · First version (MVP)
After that
A delivered app isn't finished. I keep it running.
From €250excl. VAT / month, depending on the size of the app
No fixed term.
DetailsYou already have a team
A team or suppliers, but nobody to make the technical calls. I take on that role, for the time you need.
From €700excl. VAT · per month
One specific task for your software to handle
A tool plugged into your software that runs a repetitive task end to end: requests, quotes, signatures, incoming documents. Fixed price given after the call. After that, maintenance from €250 excl. VAT / month.
Finding your bearings
The price depends on how long the build takes, and that is set during scoping. The maths, at least, is simple:
2 weeks of build
€6,500
A simple tool, or a very focused first version. Includes two days of scoping.
1 month of build
€11,900
A focused tool, or a first version to put in your users' hands.
2 months of build
€23,800
A complete business application, from design to production.
Plus scoping, €1,900, deducted if you continue. Amounts excluding VAT. The number of months is estimated during scoping and written into the quote.
| Offer | What you get | How it is billed | Price |
|---|---|---|---|
| Scoping | The plan of what we build and in what order, mock-ups of the key screens, a schedule, a fixed price. For a takeover: the state of the code, what we keep, what we fix, what we redo. It all belongs to you, even if you continue with someone else. | One week, fixed price. Deducted from the Build if you continue. | €1,900 |
| Build | Screen design, web, iOS and Android development, the back office, going live, store publishing, documentation and training for your teams. | Monthly, fixed price, or €6,500 for two weeks on a short project, including two days of scoping. A demo every week. | €11,900/month |
| Care | Maintenance of your app, security updates, fixes and small improvements. | Monthly, no long-term commitment. The amount follows the size of the app and is set with you. | From €250/month |
| Fractional CTO | Technical decisions, the roadmap, a meeting every month, reviewing your suppliers' work. | Monthly, no long-term commitment. The amount depends on the time you need and is set with you. | From €700/month |
| Automation | A tool that runs a repetitive task, plugged into your software. Your team keeps the final say. | Fixed price, given after the call, before work starts. After that, maintenance by the month. | Given after the call |
The framework
Currencies
You are invoiced in your currency. All prices shown exclude VAT.
Confidentiality
On request, before you give me access to your code or your data.
Personal data
Who does what with your users' data is written into the contract.
Reversibility
No penalty. Everything is already in your name: you leave with all of it.
Questions about prices
As a fixed fee. At scoping, we define what will be built, and the price is written in the quote. As an order of magnitude: from €6,500 for two weeks, from €11,900 for a month. You know what you pay before you commit.
What is seen at scoping is in the fixed fee. If the need changes along the way, I tell you right away and we choose together: adjust the scope, or price what is added before starting it. A weekly demo shows you where we are.
The price depends on the size of the project: a small development of a few days is priced separately, it does not fall under the two-week flat fee. For one or two weeks, the build is billed a flat €6,500 excl. VAT, with a short scoping of two days included. For three or four weeks, it's one month. Beyond that, months, plus a two-week flat fee if one or two weeks remain.
No. You leave with the plan, the mock-ups and the schedule, usable by the supplier of your choice.
Maintenance of a small app: its security updates, its fixes, small improvements. For a larger app, the price follows its size; we set it together. The details are on the Maintenance page.
A fixed price, given after the call, before work starts: it depends on the task and the software to connect. After that, maintenance from €250 excl. VAT a month.
Care looks after an app I built or took over. The fractional CTO steers the tech of your company: the decisions, the roadmap, your suppliers. The two can be combined.
You stop whenever you want, no penalty. The code, the access and the documentation are already yours: you leave with everything.
