The verdict in three sentences
SaaS wins when your need is standard and you accept adapting to the tool; the freelancer wins on small, well-scoped jobs where price beats guarantee; the agency wins as soon as the project is critical, multi-disciplinary or meant to last more than three years. The real cost is not the day rate but the takeover cost if it fails: rescuing an abandoned project runs 30 to 60 % of the original budget. Decide your acceptable risk level first, and the model follows almost mechanically.
The three models across seven criteria
The figures below are 2026 estimates for the French/EU market (ex-VAT), useful for framing a budget before you consult anyone.
| Criterion | Freelancer | Agency | SaaS |
|---|---|---|---|
| Entry cost | 4,000-9,000 EUR (brochure site) | 9,000-20,000 EUR | 30-300 EUR/month |
| Day rate | 250-550 EUR/day | 500-900 EUR/day | Not applicable |
| Time to start | 1-4 weeks | 3-8 weeks | 1-5 days |
| Guarantee / commitment | Low (light contract) | Strong (contract, SLA) | Medium (vendor T&Cs) |
| Scalability | Limited to one person | High (team) | Capped by vendor roadmap |
| Dependency | Bus factor = 1 | Spread across the team | Vendor lock-in |
| Support / maintenance | Variable, not guaranteed | Formal support contract | Standard support included |
The most common blind spot is the freelancer's bus factor. If the one person who knows the code falls ill, takes long leave or changes career, your project stops. An agency spreads knowledge across several developers and documents the code by contract.
Real cost over three years, not at launch
The entry price misleads. What matters is the total cost over 36 months, maintenance and incidents included.
| Line item (3 years) | Freelancer | Agency | SaaS |
|---|---|---|---|
| Initial development | 7,000 EUR | 15,000 EUR | 0 EUR |
| Subscription / licences | 0 EUR | 0 EUR | 5,400 EUR (150 EUR/mo) |
| Maintenance / support | 2,500 EUR (if available) | 4,500 EUR | Included |
| Takeover risk (probability-weighted) | 2,800 EUR (40 % × 40 % budget) | 900 EUR | 0 EUR |
| Estimated 3-year total | ~12,300 EUR | ~20,400 EUR | ~5,400 EUR |
SaaS is cheapest as long as the standard fits; the moment you must bend the tool to a specific business process, workaround costs explode and custom agency work becomes rational again.
Mini case study
Thomas, owner of a 22-person wholesale SME in Nantes, wants a customer ordering portal. A generic SaaS at 200 EUR/month cannot handle his volume-tier pricing. The freelancer quotes 8,500 EUR but works alone. The agency quotes 16,000 EUR with two developers and a support contract. Thomas runs the numbers: if the freelancer quits halfway, the takeover will cost roughly 40 % of 8,500, i.e. 3,400 EUR lost, plus three months' delay. With 4.2 M EUR of revenue riding on that portal, he picks the agency: the extra 7,500 EUR is a rational insurance premium against a business outage.

FAQ
Is a freelancer always cheaper than an agency?
Per day yes (250-550 EUR vs 500-900 EUR), but not over the life cycle. Across three years the gap narrows because of unguaranteed maintenance and the takeover risk priced at 30-60 % of the original budget.
When does SaaS become a bad choice?
As soon as more than 20-30 % of your needs require manual workarounds or exports. Beyond that, the time your teams waste usually exceeds the 30-300 EUR monthly subscription, and custom becomes worthwhile.
How do I limit a freelancer's bus factor?
Contractually require a documented code repository, a written handover and access to hosting. Budget 1-2 billed days (250-1,100 EUR) to secure this reversibility, far less than a full rescue.
Can I mix the models?
Yes, and it is often optimal: SaaS for accounting, an agency for the differentiating business tool, a freelancer for one-off tweaks. The key is keeping ownership of the code and data on the strategic part.
How much should I budget for maintenance after delivery?
Expect 8 to 20 % of the development cost per year. On a 15,000 EUR project that is 1,200 to 3,000 EUR annually to budget from day one, otherwise the app degrades within 24-36 months.
