Short answer

How much does a project cost at Krafter?

A mobile app or SaaS MVP starts at €6,000 excl. VAT when your need is defined: processes, business rules and screens already set. The price goes up if that thinking has to be done with you, or if payment is needed. This floor comes from three choices: an open source foundation that is not billed again on every project, two senior partners who work with AI and review every line, and no sales layer between you and the code.

Mobile MVP
€6,000 to €25,000 excl. VAT, 8 to 12 weeks to the stores.
SaaS MVP
€6,000 to €30,000 excl. VAT, 4 to 8 weeks.
Complete product
€25,000 to €60,000 excl. VAT for mobile, €40,000 to €80,000 excl. VAT for SaaS.
Discovery
€3,000 to €6,000 excl. VAT on top, if the need still has to be shaped.
Payment
€2,000 to €5,000 excl. VAT one-off, €4,000 to €10,000 excl. VAT subscription.
Maintenance
8 to 12% of development per year, then new features on time spent.

Estimate my budget

The floor

€6,000 excl. VAT: a real floor, on one condition.

The entry price applies when you know exactly what you want: processes, business rules and screens already defined. Development then starts right away.

An open source foundation. The groundwork of your product already exists, proven on our own products in production. It is not billed again on every project: your budget goes to what makes your product unique.

Two senior partners. AI writes a large share of the code, and every line is reviewed and tested by Fabien Maquin or François Pluchino.

No sales layer. No salesperson to pay, no middleman between you and the code. In return, if the thinking still needs doing, discovery is added: €3,000 to €6,000 excl. VAT.

What moves the price

Five choices move the price.

A project’s price depends mostly on five choices: discovery, payment, integrations, offline mode or geolocation, and the number of roles. Each one is settled before development.

Discovery

+€3,000 to €6,000 excl. VAT

If your processes, business rules and screens still need shaping, discovery sets them with you before the first line of code. It ends with a costed scope and a written list of what waits for version two.

Payment

+€2,000 to €5,000 one-off, +€4,000 to €10,000 subscription

Taking money online means extra screens, rules and tests. Subscriptions cost more than one-off payments: sign-ups, invoices and reminders all have to be handled.

Integrations

€2,000 to €15,000 excl. VAT per connection

Each connection to an ERP, a CRM or an invoicing tool is priced on its own. A one-way sync stays at the low end, two-way flows between several systems go higher.

Offline mode or geolocation

€30,000 to €70,000 excl. VAT

An app that must work without a network or track locations moves to another category, for 4 to 6 months of work. Local storage and deferred sync call for real architecture.

Number of roles

up to the top of the range

A single user profile fits the low end. Each extra role adds screens, access rights and tests. With several roles, an MVP nears €25,000 excl. VAT for mobile, €30,000 excl. VAT for SaaS.

What brings the bill down

  • A need that is already defined: discovery drops off the bill. To prepare it on your own, start from our specification template.
  • A disciplined scope: whatever does not serve version one goes on a written list for version two.
  • Flutter on mobile: one codebase for iOS and Android, so one budget for development and maintenance.

Included

What every project includes.

Whatever its price, every project runs the same way: two senior partners from start to finish, reviewed code, and a product you own.

Two senior partners, your only contacts

Fabien Maquin and François Pluchino scope, design and code themselves, from the first call to going live. Work happens over video, wherever you are.

Reviewed, tested code

AI writes a large share of the code. Every line is reviewed and tested by a senior partner before it reaches production.

Everything in your name

At the end of the project, the Git repository, store and cloud accounts and all access are transferred to you. Only the open source stack stays under its own licence.

Hosted in France, or on your side

Your product is deployed with a French hosting provider, or on your own infrastructure if you prefer.

Store publication

For a mobile app: store listings, submission and follow-up of the Apple and Google review.

After delivery

After delivery, two tiers of maintenance.

Delivered software is maintained in two tiers: upkeep, so it stays secure and publishable, then new features, at the pace of your roadmap.

Upkeep

8 to 12% of the development cost per year. Security, dependency updates, compatibility with each new iOS and Android version. Without it, an app ends up pulled from the stores.

New features

On time spent, at €700 to €1,100 excl. VAT per day, or as prepaid time credit. The same code, looked after by the same partners.

An app built elsewhere

Before taking it over, a 1 to 3 day audit, or €700 to €3,300 excl. VAT: written report, costed plan and video debrief.

Maintenance in detailGet an app audited

External costs

External costs to plan for.

Three costs come on top of the development price, depending on your product.

  • The stores: $99 a year for the Apple developer account, a one-time $25 for Google, paid directly on accounts in your name.
  • Hosting: with a French provider or on your infrastructure, its cost depends on how your product is used.
  • Payment: the provider that collects the money takes its own fee on each transaction.

Transparency

Why publish our prices?

Because hidden prices waste everyone’s time. You know before the first call whether your budget fits your project.

The first conversation is then about your product, not about guessing a range. And a quote from elsewhere can be compared line by line: if it strays far from this rate card, the right question is not “why so expensive” but “what does it cover more, or less”.

The studio, founded in 2021 in Morancé near Lyon, France, works over video with founders and companies.

Pricing questions, one by one.

At Krafter, a mobile MVP costs €6,000 to €25,000 excl. VAT, for iOS and Android from a single Flutter codebase. A complete app sits between €25,000 and €60,000 excl. VAT, over 3 to 5 months. With offline mode or geolocation, allow €30,000 to €70,000 excl. VAT, over 4 to 6 months.

A SaaS MVP costs €6,000 to €30,000 excl. VAT, for 4 to 8 weeks of development. A complete platform, with subscriptions, dashboard, API and separate customer spaces, sits between €40,000 and €80,000 excl. VAT, over 10 to 16 weeks. Online subscription billing adds €4,000 to €10,000 excl. VAT.

An MVP costs €6,000 to €25,000 excl. VAT as a mobile app and €6,000 to €30,000 excl. VAT as a SaaS, for 4 to 8 weeks of development. The low end covers one core feature and a single user profile. Several roles and a full back office push the price up.

Because the need is already defined: processes, business rules and screens are set, so development starts right away. The rest comes from three choices: an open source foundation that is not billed again, two senior partners who work with AI and review every line, and no sales layer. Otherwise, discovery adds €3,000 to €6,000 excl. VAT.

A simple internal tool, with a few screens and one workflow, costs €6,000 to €15,000 excl. VAT over 3 to 5 weeks. A complete business application, with advanced workflows and several integrations, sits between €20,000 and €60,000 excl. VAT, over 8 to 14 weeks. Each connection to an existing tool adds €2,000 to €15,000 excl. VAT.

It is budgeted in two tiers. Upkeep (security, updates, compatibility with each new iOS and Android version) runs at 8 to 12% of the development cost per year. New features are then billed on time spent, at €700 to €1,100 excl. VAT per day, or as prepaid time credit.

The stores charge their own fees: $99 a year for the Apple developer account, a one-time $25 for Google. These accounts are opened in your name. Preparing the store listings, submitting the app and following the review are included in our mobile projects.

One-off payments add €2,000 to €5,000 excl. VAT to the project. Online subscriptions, with sign-ups, invoices and payment reminders, add €4,000 to €10,000 excl. VAT. On top of that, the payment provider takes its own fee on each transaction, outside our invoice.

Allow €2,000 to €15,000 excl. VAT per connection. A simple one-way sync of a few data types sits at the low end. Two-way flows between several systems, with data transformation and advanced error handling, sit near the top. Each connection is priced on its own.

A takeover audit takes 1 to 3 days, or €700 to €3,300 excl. VAT depending on the size of the app. You get a written report, a costed plan and a video debrief. If the audit recommends a rewrite, it follows the MVP rates: €6,000 to €25,000 excl. VAT for mobile, €6,000 to €30,000 excl. VAT for SaaS.
