Selling to Spanish sole traders (autónomos): what works
Half of Spanish small businesses in our directory are autónomos. How they buy, when to call, the data protection rules that apply and the mistakes foreign sellers make.

If you sell to Spanish small businesses, you are mostly selling to individuals. In our directory, 245,728 of 492,043 records are autónomos (self-employed sole traders), 49.9% of the total, and 92.6% of them have 0 to 2 employees. The full figures are in our 2026 report on Spanish SMEs and sole traders.
An autónomo is a person registered in Spain's social security scheme for the self-employed: a plumber in Albacete, a physiotherapist in Gijón, a translator in Valencia. Legally and commercially, that is different from selling to a company.
How sole traders differ from companies
| Company with staff | Autónomo | |
|---|---|---|
| Decision | Several people | One person who also does the work |
| Availability | Office hours | Between jobs, in the van, evenings |
| Payment | Bank transfer, 30-60 days | Small, predictable monthly fees |
| Priorities | Processes, reporting | Time, cash flow, simplicity |
| Contact | Switchboard, corporate email | Personal mobile, often Gmail |
| Data protection | Legal entity | Natural person |
The legal framework
Because a sole trader is a natural person, the GDPR and Spain's Organic Law 3/2018 (LOPDGDD) apply.
- Legal basis. Article 19 of the LOPDGDD presumes that processing data about individual entrepreneurs and liberal professionals is covered by legitimate interest when they are treated only in that capacity. A booking app for a hairdresser fits; a personal life insurance offer does not.
- Robinson list. Screen numbers against Spain's Robinson opt-out list before calling.
- Objections. If they ask not to be called again, record it and stop.
- Email and messaging. Article 21 of the LSSI bans commercial electronic messages that were not requested or expressly authorised. Call first; email when asked.

What works
Calling the mobile, in Spanish, at the right time. 92.9% of the phone numbers in our directory are mobiles. Tradespeople who work on site answer best early in the morning or late afternoon; those with a practice or shop, before opening or between appointments. Spanish working days run later than in northern Europe, often with a long lunch break.
Talking about their work. "Do you write your quotes on your phone or on paper?" starts more conversations than a company introduction.
Pricing that fits a monthly budget. Sole traders compare your fee with their monthly social security contribution and with what they earn in a day. A small monthly fee without a long commitment can be decided on the call.
Doing the set-up for them. "I will configure it for you" is worth more than a discount to someone with no spare evening.
Respecting the tax calendar. Quarterly VAT and income tax returns fall in April, July, October and January. Those weeks are busy for autónomos, unless what you sell helps with exactly that. Check exact dates in the AEAT taxpayer calendar.
Localised support. Spanish-language onboarding, invoices that meet Spanish requirements and a Spanish phone number for support make the difference between a trial and a customer.
What does not work
- Automated email sequences. Legally risky and ignored by busy owners.
- Hour-long demos. Ten minutes on their own phone.
- Long contracts and fine print. Spanish sole traders are wary of lock-in, with reason.
- Enterprise vocabulary. There is no procurement team or IT manager: it is them.
- Using their data for personal offers. The Article 19 presumption covers their professional capacity only.
Where autónomos are concentrated
The share varies widely by province in our data: sole traders are a majority in Melilla (66%), Las Palmas (65%), Ceuta (64.4%), Santa Cruz de Tenerife (63.5%) and Ávila (63%), and a minority in Álava (34.5%), Bizkaia (36.5%) and Gipuzkoa (40.8%). If your product is built for one-person businesses, the Canary Islands and inland Castile are a natural start; if it needs a team, the Basque Country has more companies.
Building the list
Filter by activity and province, separate sole traders from companies and segment by headcount. Prepare the call with our cold call script for Spain and send a short follow-up email when they ask for details. The B2B sales use case covers getting it all into your CRM.
Frequently asked questions
What is an autónomo?+
A self-employed person registered in Spain's special social security scheme for the self-employed. Many trades, shops and professional practices are run by autónomos rather than companies.
Can I call a Spanish sole trader to sell a business product?+
Generally yes. Article 19 of Spain's data protection law (LOPDGDD) presumes legitimate interest when data about individual entrepreneurs is used only in that capacity. Check the Robinson list and honour objections.
Can I email Spanish sole traders?+
Only with prior request or express consent, or to existing customers about similar products with an opt-out. Article 21 of the LSSI applies to businesses and individuals alike.
