Setting up in Spain: the operational checklist, not the legal one
Corpshore Spain editorial team · · 6 min read
In summary: this checklist covers the operational layer of a Spanish market entry, customer service, back office, IT support and staffing, and deliberately excludes incorporation, tax regime and employment obligations, which belong to your legal and tax advisors.
Most guides to setting up in Spain mix two different things: what a lawyer or tax advisor decides, and what has to be working before you can serve the first customer. Mixing them produces long lists in which the urgent gets lost.
This list covers only the second. We state plainly where it ends: we do not provide legal or tax advice and we work alongside your advisors, not in their place.
What has to be working before the first customer?
A Spanish-language support channel with an identifiable person behind it. A Spanish client signing with a foreign company soon tests whether they can talk to someone, and a number nobody answers does more damage than publishing no number.
A working contact address and a complaints route. If your company will fall within the scope of Law 10/2025 by size or sector, it is worth designing this from the outset with its deadlines in mind rather than rebuilding it later.
Invoicing in euros and an administrative process able to issue and record in line with your tax position, which is where your advisors need to rule.
How do you hire before having an entity?
There are two common routes and the choice between them is yours and your advisors'. The first is outsourced staff, where the provider is the employer and you contract a service. The second is direct hiring managed by a third party on your behalf, where you are the employer.
The difference is not price but responsibility. In the first case employment obligations sit with the provider; in the second, with your company, including those arising from pay transparency rules once transposed.
What is common to both: the Spanish labour market carries an employer cost of between 31 and 35 percent on top of gross salary, and it is worth building into the model from the start rather than discovering in month four.
What must be resolved on data protection from day one?
If you process personal data of people in the European Union, GDPR applies from the first customer, regardless of where your company is incorporated.
The point that most surprises a foreign parent is the flow back to it. Sending European data to a parent in a country without an adequacy decision requires standard contractual clauses and, depending on sensitivity, a transfer impact assessment.
It is worth having the data processing agreement ready before the first serious negotiation, because a mid-sized Spanish client's procurement department will ask for it.
What is usually underestimated?
Language beyond Castilian. If your target market is in Catalonia, the Basque Country or Galicia, co-official language support appears as a requirement in the public sector and as a retention factor in the private one.
The calendar. August slows much of Spanish commercial and administrative activity, and an entry plan that ignores it accumulates delays later attributed to other causes.
And service expectations. Sharing a language with a market does not mean sharing expectations, and the difference shows in support metrics before it shows anywhere else.
In what order should it be done?
First, what blocks invoicing: the ability to issue an invoice and get paid, with your advisors' view on legal form.
Second, what blocks serving customers: a working Spanish-language channel and someone accountable for the client relationship.
Third, what blocks scaling: the staffing model, which is worth validating with a small team before committing fixed structure.
And alongside all of it, the data protection documentation, because it arrives earlier than expected in any serious negotiation.
