A software development company designs, builds and maintains applications for a client. It sells that work as developer time, as a fixed-price project or as a dedicated team. The right choice doesn't come down to the brochure or the headline price. It comes down to who takes responsibility for the outcome once the code ships. I've watched enough projects go off the rails to say this plainly: the quote is the least informative part of the whole bid.
- 🎯 Responsibility for the outcome, the real deciding factor, well ahead of price or size.
- 📉 Unchecked AI code, 30% more code written, but no more finished software.
- 🌍 Senior offshore team, a balance of quality, speed and cost that's hard to beat in 2026.
- ✅ Five decisive questions, to ask before you sign, whoever the provider is.
Here's the plan: what these companies actually sell, why understanding your needs matters more than the quote, what AI changes in how you assess them, which model fits your situation, and then my verdict.
What does a software development company really sell?
A software development company sells delivery capacity: engineers, a method and a commitment to an outcome. The code is only the visible part. What you're paying for is turning a fuzzy idea into a product that runs in production and that someone knows how to maintain.
What kinds of companies are on the market?
The market is mixed. Custom development agencies such as 4SH or ANURA (based in Bourg-en-Bresse and operating since 2017, according to its website) focus on business software and end-to-end support. Large international groups such as Innowise highlight their Clutch awards, for example their 2023 e-commerce award. Comparison sites such as Sortlist publish "top 10" rankings of French agencies for 2026.
These rankings have one flaw: they measure how visible a company is commercially, not how well it delivers. A company that ranks well isn't necessarily the one that will hit your deadlines.
Why is the word "development" a trap?
The Beyond The Grid podcast asks an uncomfortable question: does a software development service without R&D make any sense? The argument is that many companies do "accelerated reproduction", meaning they assemble known building blocks instead of exploring anything new. I don't agree with all of it, because clients don't pay for research. But one part of the point holds: a company that only repeats its usual recipes won't protect you on the day your needs fall outside them.
A good provider knows how to say "this is new, let's prototype it first". A bad one prices everything with the same confidence.
Why does understanding your needs matter more than the quote?
You win or lose with a software development company during scoping, not on the price line. A provider who prices your project without understanding your problem is selling you an estimate, not a commitment. That's the first signal to watch for.
How did a young firm win a client with a slower quote?
Oriana Solutions, a Quebec firm, was one year old when it recorded its video. It was founded after winning the Ose entreprendre competition, and it says it has around ten clients and three co-founders with clearly split roles: a developer, an architect who picks the stack, and someone who handles client relations. One client told them they were chosen because they were the only ones who took the time to understand his motivations and what he actually needed. Their proposal went out later than the competitors' bids, which were a single page with a price at the bottom.
That account backs up my view: a slower quote is often the sign of serious scoping. A 24-hour quote on a complex project is a red flag, not a selling point.
Why do agile methods change how you read the contract?
In its presentation, the training organisation INSAVALOR points out that software is under two pressures: changing technology and changing client demands. In traditional project management, you sign the contract and then deliver at the end. Agile approaches challenge that model so they can absorb change along the way.
The practical upshot: a fixed-price contract locked to a 40-page scope does little to protect you if your market shifts within three months. For a product that keeps evolving, I prefer time and materials with regular progress check-ins, or a fixed price split into short phases.
How does AI change the way you assess a software development company?
AI increases code output but moves the bottleneck to verification, which means the quality of the team doing the reviews matters more. Assessing a software development company in 2026 means assessing how well it checks what the tools produce, not how fast it types.
What does the Harvard study on coding agents show?
Fiona Chen and James Stratton's paper, "Artificial Intelligence in the Firm: Bottlenecks in Software Production", was shared on r/artificielle. It analyses around 300 million work events across 718 companies and finds that introducing AI coding agents raises code output by about 30% without producing more finished software. The time from opening a pull request to merging it goes up by 49%, change requests become almost twice as frequent, and review comments rise by 35%.
So agents speed up the writing, and then humans spend the time saved checking and fixing it. That matches what I see: producing code with AI doesn't mean knowing how to build a product.
A skilled developer equipped with Claude Code or Cursor is still an engineer, not a prompt operator.
Is AI replacing developers?
An analysis of Current Population Survey data, posted on r/ExperiencedDevs, shows US developer employment rising from an average of about 2.2 million in 2022 to nearly 2.6 million over January to September 2026. The author reads this as tools that augment developers rather than replace them.
I agree. Strong developers become more productive, while average ones become riskier, because AI gives them the illusion of mastering code they don't review. For a buyer, the useful question is: how does this company review, test and document what AI generates? My article on the signs a provider is bluffing you about AI agents covers the answers that should worry you.
Which model should you choose: local agency, IT services firm, freelancer or dedicated offshore team?
The right model depends on how long you need the work done, how much steering you can do yourself and your budget. There's no universal answer, but in some situations one option is clearly the best. The table below compares the four most common routes for a French SME or scale-up.
| Model | Main strength | Main limitation | Best when |
|---|---|---|---|
| Local agency | Proximity, in-depth scoping | High cost, inflexible team | Complex product, heavy interaction with the business |
| Traditional IT services firm | Can staff up fast | Turnover, middlemen | One-off reinforcement for a large company |
| Independent freelancer | Flexibility, direct cost | Reliance on a single person | Short, tightly scoped engagement |
| Dedicated offshore team | Cost-to-speed ratio, seniority | Time zone, steering needs structure | Product that evolves over 6 months or more |

Why is a senior Vietnamese team a serious option?
I've run a team of senior developers in Vietnam since 2014, so I'm not neutral. I still stand by this choice, for concrete reasons. The technical skill available is more than enough to build SaaS products, mobile apps and business platforms. A small, well-organised senior team working with AI can compete with a far more expensive European team, and French startups don't need to burn their budget on oversized local teams.
I explain how it works in my guide to offshore software development in Vietnam and in my piece on the real cost of custom software. To compare French providers, my article on the criteria for choosing a custom software agency is still the reference. Syntec Numérique, the sector's trade association, also publishes market studies on French IT services firms and software vendors.
When should you not go offshore?
If your product needs daily on-site workshops with users, or if nobody on your side can set priorities every week, offshore will disappoint you. A remote team amplifies clear steering, it doesn't replace it. In that case, a local agency costs more but covers the gaps in your organisation.
How do you vet a software development company before signing?
Before you sign with a software development company, check five concrete things: how senior the assigned developers really are, how code gets reviewed, who owns the code and the access, how the provider handles a disagreement, and a short paid trial. These checks take a few days and can save you months of repairs.
What questions should you ask the provider?
These are the ones I'd ask as a buyer.
- Who writes the code? Ask for named profiles and their years of experience, not a vague promise of "senior developers".
- How is the code reviewed? Review by a second engineer and automated tests should be standard, especially if the provider uses AI.
- Who owns the code and the access? The repository, hosting and documentation should sit on your accounts from day one.
- What happens if a developer leaves? Insist on a documented replacement and a handover period.
- Can we start with a short trial? Five days of work measure speed and quality better than any pitch deck.
The profile I describe on my page about hiring a senior developer in Vietnam follows exactly this framework: profiles within 48 hours, start in under 7 days.
Why does a product "generated fast" often cost more?
A product generated quickly without technical oversight usually costs far more to fix than it would have cost to build properly from the start. Vibe coding is useful for prototyping, but it's still dangerous for a serious product without supervision, because architecture, security, maintenance and edge cases don't generate themselves. The analyses on AI and business that I follow closely point the same way.
My verdict: how should you choose your software development company?
Choose the company that's willing to take responsibility for the outcome, that took the time to understand what you need and that can prove it checks what AI produces. Price comes after that. For most French SMEs and scale-ups with an evolving product, my pick is a small, dedicated senior team in Vietnam, equipped with AI and steered through regular check-ins.
So should you avoid agencies and IT services firms?
No. A local agency is still the best answer when scoping requires close collaboration, and an IT services firm works for one-off reinforcement. What I advise against is signing on the strength of a quick quote and a ranking. If you want to estimate what a senior developer would cost under each arrangement, use the calculator for the real cost of a senior developer: employee, freelancer or offshore before you ask anyone for a quote.
Frequently asked questions
How much does a software development company cost?
It depends on the model: a local agency charges more than a dedicated offshore team, which in turn costs more than a junior freelancer. No single figure means anything without a precise scope. Always ask for a detailed estimate broken down by phase, with the assumptions written down.
What's the difference between an IT services firm and a development agency?
An IT services firm mostly places consultants with its clients on a time-and-materials basis, while an agency designs and delivers a complete product, often at a fixed price. Both can work either way, so read the contract model, not the label.
Should you go for fixed price or time and materials?
Fixed price suits a scope that's locked and well defined. Time and materials works better for a product that evolves, because you adjust priorities every week. A fixed price split into short phases is a good compromise.
Can AI replace a software development company?
No, not in 2026. According to Fiona Chen and James Stratton's study, AI agents increase code output by about 30% without increasing finished software, because verification becomes the new bottleneck. A serious company uses AI and keeps engineers to review, test and make decisions.
How do you know if a provider is reliable?
Look at the quality of its scoping, ask for named profiles, insist on owning the code and run a paid trial of a few days. A reliable provider accepts these checks without pushback.
