What Web Application Development actually delivers
Web Application Development means browser-based business applications: portals, dashboards, workflow tools and internal platforms.
For French teams that matters because teams are often split between a head office and regional sites, so processes that live in one person's head or one person's inbox are a genuine business risk. We build for French companies replacing spreadsheets, shared drives and email approvals with a proper platform, and we say no when a packaged product would do the job better than a custom build.
We work in React, Next.js, Node.js, Python, PostgreSQL, Redis, AWS and Azure, chosen because they are maintainable and widely supported, so you are never locked to us by an exotic technology choice.
Our certified Zoho team
Web Application Development across France
We deliver web application 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.
France runs on trading, contracting, logistics, hospitality and professional services, and almost all of it on lean teams that cannot afford software nobody uses. 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.
Most clients look at these next: Android App Development in France, App Development Company in France and Bilingual English App 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 Enterprise App Development right in France
French users expect apps that speak their language, take the payments they already use and respect their privacy. This is how we build Enterprise App Development.
French and English from the first screen
French and English content and layouts are designed in, since the Loi Toubon requires French in consumer-facing documents in France.
Payments people use
Cards, Apple Pay, Google Pay and SEPA Direct Debit through Stripe or a similar provider, with the right TVA rate on each item.
Accessible by default
Screens are built toward WCAG 2.1 AA, and toward the RGAA, the French standard that applies to public bodies.
Privacy built in
Consent, tracker opt-in, data access and deletion are designed for GDPR and the CNIL’s rules.
How a web application 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.
What French compliance means for Enterprise App Development
In France, TVA and corporate tax are filed with the DGFiP, payroll is reported every month through the DSN, and the e-invoicing reform changes how invoices are sent and received from 1 September 2026. These are the rules a French setup has to get right.
| Obligation | What the rule is | What has to be configured |
|---|---|---|
| TVA (VAT) | The standard rate is 20%, with 10% for restaurants, passenger transport and some renovation work, 5.5% for most food, books and energy-efficiency works, and 2.1% for the press and some medicines. Returns go on the CA3, monthly or quarterly for small amounts, under the régime réel normal, or on the annual CA12 with instalments under the régime réel simplifié. Intra-EU B2B trade uses the reverse charge (autoliquidation) with EMEBI and DES declarations, B2C distance sales go through the OSS, and import VAT is self-assessed on the CA3. | The right rate by item and customer, SIREN and intra-community VAT numbers on every invoice with the mandatory mentions (payment terms, late-payment penalty rate and the EUR 40 fixed recovery fee), reverse charge and OSS treatment set correctly, deductible TVA tracked, and CA3 or CA12 figures for each period. |
| E-invoicing reform | From 1 September 2026 every VAT-registered business must be able to receive structured e-invoices, and large and mid-sized companies (GE and ETI) must also issue e-invoices and e-report. SMEs and micro-businesses must issue from 1 September 2027. Invoices travel through approved platforms (Plateformes Agréées) in Factur-X, UBL or CII format, and invoices to the public sector already go through Chorus Pro. | Zoho Books' French edition producing Factur-X invoices and connected to B2Brouter, an approved platform, for sending and receiving, customer SIREN numbers captured on every account, and the full flow tested before your issuing date. |
| Corporate tax (IS) | The standard rate is 25%, or 15% on the first EUR 42,500 of profit for qualifying SMEs (turnover under EUR 10m, fully paid-up capital and at least 75% held by individuals). The annual liasse fiscale is built from accounts kept on the Plan Comptable Général, and the FEC (Fichier des Écritures Comptables) must be produced on request in a tax audit. | A chart of accounts on the PCG, entities kept separate, fixed assets recorded, and journals kept complete and sequential so the FEC can be produced on request. |
| Payroll (DSN, URSSAF, PAS) | Every month the employer files the DSN (déclaration sociale nominative) through net-entreprises.fr, pays social contributions to URSSAF and withholds income tax at source (prélèvement à la source). Payroll runs on a French payroll engine such as Silae, PayFit, Sage Paie or Cegid; Zoho Payroll is not available in France. | Zoho People kept as the HR record and connected to your payroll provider, so hires, pay changes, absences and leavers flow across without rekeying, and payroll journals posting to the ledger. |
| Employment and data rules | The legal working week is 35 hours, with RTT days where working time is set above it, five weeks' paid leave (2.5 working days per month), sector collective agreements (conventions collectives) and mandatory company health cover (mutuelle). GDPR is enforced by the CNIL, including consent before non-essential cookies, and the Loi Toubon requires French in consumer documents, employment documents and contracts. | Leave, RTT and working-time rules set per collective agreement, accounts provisioned in Zoho's EU data centre (zoho.eu), consent captured for every contact, French templates for customers and staff, and access and deletion requests handled on record. |

We configure the system to produce what these returns need, and we test it against your own transactions before go-live. We are not tax advisers: your expert-comptable signs the returns, and rates and thresholds change, so treat this as the shape of the work rather than advice. Last reviewed 24 October 2026.
