Construction Software Development in France: the short answer
- What it is
- Custom Software Development for businesses in France - building the system your business actually runs on, when nothing off the shelf fits the process.
- Typical timeline
- A focused first release is commonly 8 to 16 weeks: two to three weeks of discovery and prototype, then build in two-week increments you review.
- What it costs
- We quote a fixed price in EUR after a discovery session, broken into phases so you are never committing to the whole build on day one.
- Local specifics
- TVA at the right rate on every invoice, Factur-X e-invoicing through an approved platform ready for the September 2026 reform, Zoho People connected to your French payroll provider for the DSN, French documents where the Loi Toubon requires them, GDPR-aware data handling in Zoho’s EU data centre, and delivery on Paris time (CET/CEST).

What Custom Software Development actually delivers
Custom Software Development means building the system your business actually runs on, when nothing off the shelf fits the process.
For French teams that matters because the 20% TVA rate, the e-invoicing reform starting in September 2026, monthly DSN payroll filings and CNIL data rules have pushed businesses towards systems that produce compliant documents by default. We build for French businesses whose core process is their differentiator and does not fit a packaged product, and we say no when a packaged product would do the job better than a custom build.
We work in React, Node.js, Python, .NET, Flutter, PostgreSQL, AWS and Azure, plus Zoho Creator where low-code is the faster answer, chosen because they are maintainable and widely supported, so you are never locked to us by an exotic technology choice.
Our certified Zoho team
Custom Software Development across France
We deliver custom software development for clients in Paris, Lyon, Marseille, Toulouse, Lille, Bordeaux, Nantes and Rennes. Projects run remotely on French working hours with on-site workshops in Paris, Lyon and Marseille where discovery or training justifies it.
A parent-company licence, a group entity and a branch office often sit under one owner here, so the software has to keep entities clean while giving the group one view. Whatever the sector, the failure mode is the same: software built without the people who use it, and abandoned within a year. Discovery is where we prevent that.
Worth reading alongside this: Custom Software Development in France, Education Software Development in France and Healthcare Software Development in France.
The stack we build on
Chosen for maintainability and for the fact that you, or anyone you hire later, can work on it. Nothing exotic that only we can support.
Getting Construction Software Development right in France
Software for French businesses has to handle TVA, e-invoicing, the French language and GDPR from the first release. This is how we approach Construction Software Development.
TVA and e-invoicing by design
Anything that bills applies the right TVA rate, carries the mandatory invoice mentions and can produce Factur-X for exchange through an approved platform.
French and English
Interfaces, documents and notifications work in French and English, with French by default for users in France.
Hosting in the EU
Hosting in an EU cloud region, often in France, where your customers or sector expect it, documented with access and retention.
GDPR and the CNIL
Consent, cookie rules, access requests, breach records and impact assessments are designed in, not bolted on.
How a custom software development project runs
Five stages, a prototype before the build commitment, and a fixed price in EUR agreed up front.
Discovery and scope
Workshops with the people who will use it, a written scope and a fixed price in EUR before anything is built.
Prototype before build
A clickable prototype you review and change cheaply, so disagreements happen in Figma rather than in code.
Build in two-week increments
Working software you can see and use every fortnight, with priorities you can change between increments.
Testing and UAT
Automated tests on the paths that matter plus scripted UAT on your own scenarios before release.
Launch, handover and support
Deployment into your own cloud account, documentation, training and an optional support retainer on French working hours.
Industries we serve in France
From technology and finance to manufacturing, healthcare, retail and professional services.
Backed by a certified Zoho team
Our consultants are certified across Zoho CRM, Books, One, Creator, Analytics and People, and we stay active in the Zoho community, including Zoholics. You work with senior people who know the platform inside out.
From discovery to go-live and ongoing support, the same team stays with you, available on Paris time (CET/CEST) by call, email and screen-share.
Whether you are moving off spreadsheets or scaling an existing Zoho setup, our certified team does the heavy lifting and trains yours to own it with confidence, so your investment keeps paying off long after go-live.
