Tailored quote
No catalogue prices. We listen to your needs, scope the modules and deliver a fixed-price + fixed-timeline quote within 3 business days. The call is free, no commitment. Prices in โฌ ex-VAT, 20% VAT added.
Whatever the scope, the following is standard โ at no extra cost.
Bring these items โ a precise quote in 60 minutes.
We work on fixed-price + fixed-timeline. Delivery date is in the contract; if late, we pay 3% penalty per week (capped at 20%) under Loi Sapin 2. This works because we scope precisely from day one, avoid scope creep and use AI-assisted code. 23 of our last 24 projects shipped on time or early (references shared on the discovery call).
Yes โ hosting at OVH (Roubaix/Strasbourg) or Scaleway (Paris) of your choice, never outside the EU without explicit consent. Full GDPR compliance: DPO, processing register, privacy policy, right to erasure, data export. We hand you a signed DPA. For healthcare, certified HDS (Hรฉbergeur de Donnรฉes de Santรฉ) hosting available.
Yes, completely. All ERP/B2B portals we ship in 2025 already emit Factur-X (PDF/A-3 + CII XML) and connect to Chorus Pro for the public sector. For the 2026 rollout (B2B private via PDPs), we integrate the DGFiP-approved Plateformes de Dรฉmatรฉrialisation Partenaires. No extra migration on your side.
**The code is 100% yours.** The GitHub repo is transferred free of charge. You can continue with any other French agency or hire developers in-house. Vendor lock-in is not our model โ we retain clients through quality, not contract.
On the contrary. Our senior developer with Cursor + Claude/GPT-4 ships ~40% faster with 25% fewer bugs than a developer alone (internal measurements). AI writes code, but architecture, code review and tests go through our 12-year team. Result: same quality, faster and cheaper.
**Marketplaces:** Amazon FR/EU/US, Cdiscount, Fnac, ManoMano, La Redoute, Rakuten FR, Veepee, Darty, Bol.com, Allegro. **ERP/Accounting:** Sage 100/X3, Cegid, Pennylane, EBP, Quadra, ACD, SAP, Oracle. **e-Document:** Factur-X via DGFiP-approved PDPs, Chorus Pro. **Payment:** Stripe FR, Lydia, HiPay, PayPlug, Klarna, Carte Bancaire (CB), PayPal, SEPA. **Carrier:** Colissimo, Chronopost, Mondial Relay, Colis Privรฉ, DPD France, GLS France, UPS, DHL. If the system has a REST/SOAP API, we integrate.
Not an exaggeration โ call our references. When manual Excel/email/phone processes migrate into a portal, one panel typically replaces 3-4 back-office people. It's not about layoffs โ you redeploy those staff to higher-value functions. No forced economic layoffs imposed by digitalisation.
Logistics, e-commerce, healthcare (with Doctolib/SESAM-Vitale/Ameli), education, construction (with URSSAF DSN), restaurants (Uber Eats/Deliveroo), real estate, jewellery, B2B textile, retail, automotive, agriculture โ live projects in all these sectors. If yours isn't listed, on the call we connect you with 1-2 similar clients.
No โ the code is yours, you run it. During the 12-month warranty all bugs are on us. After: (1) an in-house developer takes over, (2) monthly maintenance contract (packs: 8 h/month โฌ690 โ 40 h/month โฌ2,980, ex-VAT), (3) hourly support (โฌ130/h ex-VAT). No commitment.
Yes โ for e-merchants subject to REP (Extended Producer Responsibility: textile, furniture, packaging, EEE, toysโฆ), our ERP/portals automatically compute TGAP eco-contribution per SKU and file with eco-organisations (Citeo, Refashion, Ecologic, ecosystem, Ecomaison). Quarterly reporting included.
Clarify cost, setup, local fit and operations for custom software development in France with ZunaPro.
Companies searching for custom software development in France usually compare more than the service name. They look for cost, timeline, a reliable team, local fit and the speed at which the project can become usable.
The page should answer technical and commercial questions together. A visitor needs to understand what will be done, in which order and what will be delivered.
ZunaPro brings workflow analysis, integrations, admin panels, reporting, automation, security and maintainable delivery into one plan. The work does not stay as a design or setup task; it becomes an operating structure the team can actually use.
In France, language, payment habits, documentation expectations, delivery or support models can directly influence the result. Discussing these points early reduces rework.
In France clean French copy, Colissimo/Mondial Relay delivery and references such as KBIS build trust.
Before requesting a quote or starting the project, these points should be clear.
| Topic | What It Clarifies | What ZunaPro Does |
|---|---|---|
| Process Analysis | Clarifies expectations, data and responsibility for Process Analysis. | Connects Process Analysis to proposal, setup and ongoing management. |
| Integrations | Clarifies expectations, data and responsibility for Integrations. | Connects Integrations to proposal, setup and ongoing management. |
| Panel And Reporting | Clarifies expectations, data and responsibility for Panel And Reporting. | Connects Panel And Reporting to proposal, setup and ongoing management. |
| Security And Maintenance | Clarifies expectations, data and responsibility for Security And Maintenance. | Connects Security And Maintenance to proposal, setup and ongoing management. |
Process Analysis sets the plan for how custom software development should be delivered in France. Scope, timeline and responsibility are written down at this stage so revisions stay rare. Once the plan is locked each team sees its own boundary and small details that look minor at first are still included in the proposal.
When the Process Analysis plan moves to the field, internal roles, approval chains and reporting cadence are defined too. Progress is measured at fixed checkpoints instead of constant meetings, and decisions follow a process rather than a single person.
In practice, Process Analysis should run as a short loop that includes team reviews, customer feedback and real data from the field. At the end of each loop the owner, timeline and expected output of the next step are written down so progress depends on a system, not on a single person.
With the right structure, teams stop recreating the same information in different places. Sales, operations, support and management can make decisions from one shared source.
During Integrations, the buyer needs to see which step happens in which order and what is delivered. Local language, payment and compliance details for France are discussed here. A transparent process shortens revision cycles, reduces knowledge loss between teams and keeps the delivery calendar reliable.
During Integrations, real user scenarios from the France market are tested. Whether the local customer prefers phone, message or a form, and where they hesitate during payment, becomes visible at this stage.
A small but critical detail in Integrations is the content approval chain. Every sentence going live in France should be reviewed once more by a local reader; this protects brand tone, legal fit and conversion potential at the same time.
ZunaPro turns custom software development into a measurable and durable software system aligned with real business workflows by managing scope, technical setup, content structure, tracking and improvement together.
Panel And Reporting is the area that creates the gap between a quote and the real cost. For brands researching Custom Software Development, scope width, content production and integrations shape the total budget. When cost lines are listed individually, comparing offers becomes easier and ROI can be measured from the start.
To read the Panel And Reporting cost line correctly, one-time and monthly figures must sit on separate rows. As scale grows in France, integrations, content updates and reporting drive most of the recurring spend.
The Panel And Reporting cost line requires the recurring and variable parts to be visible in writing. Growth decisions like a seasonal campaign, an extra language or a new product category should already be marked on the budget.
Looking only at the starting price can be misleading. Maintenance, integrations, number of languages, reporting and security requirements shape the real value.
Security And Maintenance keeps living after launch. To keep selling in France, maintenance, reporting and content updates must be planned from day one. Without a clear post-launch plan a project erodes within months; a steady support routine keeps brand value intact.
The Security And Maintenance block must turn into a loop of analysis, content refresh, campaign work and technical maintenance. As traffic grows in France, every part of this loop needs a clear owner.
The Security And Maintenance block must be fed continuously with customer questions, support tickets and performance data. As live traffic grows in France, the behaviour patterns that emerge are the most valuable input for setting the priorities of the next release.
A strong service page clearly explains what the buyer gets, what stages they pass through and which workload is removed from their team.
Every project is different, yet custom software development work in France usually follows a similar order. The steps below summarise the practical path from the first call to going live and clarify what to look for when reading a proposal.
Many companies make a custom software development decision based only on the starting price. Maintenance cost, local fit and missing reporting often force the project to be rebuilt months later.
When planning custom software development for France, local language, payment habits and official procedures should be discussed early. Customer trust is built when contact, invoicing, delivery and support stay consistent.
France brings regional delivery, return experience and French support expectations into warehouse and fulfillment decisions.
ZunaPro brings workflow analysis, integrations, admin panels, reporting, automation, security and maintainable delivery into one plan. The work does not stay as a design or setup task; it becomes an operating structure the team can actually use.
In France clean French copy, Colissimo/Mondial Relay delivery and references such as KBIS build trust.
The three scenarios below show how custom software development positions itself at different scales in the France market. The goal is for each business to spot the profile closest to its own situation and to ask the right questions from the start.
A custom software development proposal for France should show its components clearly. Itemised quotes prevent later surprises and make comparison between providers possible.
The value of Custom Software Development comes not from launch day but from the steady support that follows. As customer behaviour, campaigns and technical needs in France change, the site, system or operation must adapt with them.
In France, language, payment habits, documentation expectations, delivery or support models can directly influence the result. Discussing these points early reduces rework.
It suits companies entering a new market, improving digital sales or organizing an existing operation.
Target market, service scope, languages, payment or contact flows and technical needs should be assessed together.
Scope, integrations, content depth, design needs, official requirements and support model affect pricing.
