If you’re looking for a custom software company for SMBs in Spain, you already know the market is a minefield. The Kit Digital program made it crystal clear: agencies charging maximum subsidies for €450 template websites, contracts with hidden clauses, and the Spanish tax authority investigating fraud through 2030. That was with subsidized money. Imagine how some behave when you’re paying out of pocket.

This article cuts straight to the point: what to look for, what to ask, and which red flags will cost you dearly if you ignore them.

The Real Problem with Spain’s Software Market

There are over 120,000 unfilled tech positions in Spain. That means many agencies hire whoever they can, not whoever they should. The result is a cycle you know well: a project that starts with a senior profile in the sales meeting and ends up built by someone with two years of experience charging as if they had ten.

Spain has 2.9 million SMBs. 89% consider digitalization critical for survival, but 42% admit they lack the internal knowledge to evaluate what they’re being sold. That gap is exactly where some agencies make their money.

The good news: with the right criteria, you can filter in the first meeting.

5 Red Flags You Must Spot Before Signing

1. They Give You a Quote on the First Call

An accurate budget can’t come from a 30-minute meeting. If it does, it means one of two things: either the project is underestimated (and the extras are coming), or they’re using a generic template that doesn’t reflect your case.

A serious company asks uncomfortable questions before quoting. What exact processes do you want to automate? What systems do you already use? How many simultaneous users do you need? If they’re not asking any of this, they don’t understand your business.

2. They Won’t Tell You Who’s Working on Your Project

“Our team” is not an answer. Demand to know exactly who will develop your software, how many years of experience they have, and how many projects they’re juggling simultaneously. If they won’t tell you before signing, they’ll hide it throughout the entire project.

3. Their References Are Untouchable

Any solid company should be able to give you three clients willing to talk to you on the phone. Not logos on a website. Not text testimonials. A real phone call. If they don’t offer it, there’s a reason.

4. The Contract Doesn’t Specify Code Ownership

The code you pay for must be yours. Some contracts include clauses where the agency retains rights over the developed software, especially if they offer a “discount” in exchange. Review this point with your lawyer before signing.

5. Long Delivery Cycles with No Interim Visibility

If the delivery cycle is “in three months we’ll show you something,” run. Custom software projects that work use short sprints with frequent demos. You should see progress every two weeks at most.

The Questions You Need to Ask Before Hiring

These aren’t courtesy questions. They’re screening questions.

About the team:

Who specifically will work on my project? Can I meet that person before signing?
How many projects is that person handling simultaneously?
How long have the developers you’d assign to me been with the company?

About their experience:

Can you show me two or three completed projects similar to mine in sector and complexity?
Can I speak directly with those clients?

About the process:

What’s your development methodology? Do you work in sprints? How frequently?
How do you handle scope changes mid-project?
Who will be my day-to-day point of contact: an account manager or the developer?

About costs and contract:

What exactly does the budget include? (design, testing, deployment, documentation)
What situations will generate additional charges?
Who owns the source code after delivery?
What does the maintenance contract include and at what cost?

How Much Custom Software Costs in Spain: Real Ranges

The Spanish market in 2025-2026 has these approximate ranges:

Project type	Investment range
Specific automation or simple tool	€3,000 – €15,000
Basic web application / MVP	€15,000 – €30,000
Medium-complexity web platform	€30,000 – €60,000
Complex application with integrations	€60,000 – €150,000

Hourly rates in Spain range from €35–90/hour at specialized agencies, up to €300–600/hour at large consultancies. Independent freelancers charge between €29–41/hour, with the project abandonment risk that entails.

Rule of thumb: any budget below €10,000 for a real business application (CRM, ERP, management platform) should make you ask what’s not included.

The Fixed-Price Model: What It Means and Why It Matters

Most agencies work on time & materials: you pay by the hour, scope changes, budget grows. It’s comfortable for the agency and risky for you.

Fixed pricing requires the company to do their analysis work properly from the start. If they propose it and back it up with a serious discovery process, that’s a sign they know what they’re doing. If they propose it without having asked questions, it’s a promise they’ll break through contract clauses.

Demand that the fixed-price contract specifies exactly what’s included in scope and what process is followed to manage changes.

Custom Software vs. Off-the-Shelf: When Each Makes Sense

Not everything needs custom development. Here’s the practical criteria:

Use an off-the-shelf solution (SaaS) if:

Your processes are standard and you don’t have proprietary workflows that no tool covers
Your team can adapt to the software without losing efficiency
The cost of internal adaptation is lower than the cost of development

Invest in custom software if:

You have very specific processes that generic SaaS tools don’t cover 100%
You use multiple systems that don’t communicate with each other and it costs hours every week
You’ve tried two or three market tools and none fits how you work
You’re losing 4–6 hours daily on tasks that should take minutes

Custom software isn’t a luxury. For many SMBs with proprietary workflows, it’s the only way to scale without hiring more people to do the same manual work.

How to Evaluate a Technical Proposal Without Being Technical

You don’t need to know how to code to spot a quality proposal. Here are the indicators:

Includes a prior analysis process: before developing, they should propose a discovery phase where they define exactly what will be built
Specifies technologies and justifies the choice: not “we use the best technologies,” but “we use React for the frontend because it enables X and Node.js for the backend because Y”
Includes testing phases: if the budget doesn’t mention QA, you’ll pay for bugs later
Has clear delivery milestones: concrete dates with defined deliverables, not “approximately in Q3”
Includes a transition plan: how do you migrate your current data? How is your team trained?

Offshore vs. Spanish Company: The Real Cost

The “offshore is cheaper” argument looks solid on paper. But the hourly rate difference disappears quickly when you add up:

Meetings at incompatible hours
Code reviews due to business context differences
Extra documentation needed to bridge the cultural gap
Project restarts when the team changes (and it changes frequently)

For a Spanish SMB with processes specific to the local market, working with a company that understands the Spanish business context, the regulatory framework (GDPR as applied here), and that you can call during business hours, has a real economic value that rarely appears in the initial budget but always shows up in the final cost.

Frequently Asked Questions

How long does it take to develop custom software for an SMB? It depends on complexity, but a medium-complexity project (€30,000–€60,000) typically takes 3–5 months working with agile methodology. Projects that promise shorter timelines without technical justification usually compromise quality or scope.

What happens if the company disappears after delivering the project? That’s why source code ownership must be clear in the contract. If the code is yours and well-documented, any other developer can continue the work. Demand that code is delivered in a repository under your control from the first sprint.

Is it necessary to sign an NDA before the first meeting? It’s not mandatory for an initial meeting where you discuss general needs, but yes before sharing operational details, client data, or internal business flows. A serious company won’t push back on signing a basic confidentiality agreement.

How do I know if the budget I’m given is reasonable? Request quotes from three different companies using the same requirements document. If one is significantly lower than the other two, ask exactly what it doesn’t include. The lowest price is rarely the most economical at the end of the project.

Can I ask for references from projects similar to mine in my sector? Yes, and you should. If the company has worked with other SMBs in your sector, they should be able to show it. Sector experience reduces onboarding time and the risk of business misunderstandings.

The custom software market for SMBs in Spain has serious companies that do their work well. The selection process you just read will help you find them and discard those that aren’t — before it costs you time and money to find out the hard way.
