In Spain, the acronym SAT — Servicio de Asistencia Técnica — describes what the rest of the world calls field service management. Spanish companies offering technical repair and maintenance services have used this term for decades. The software category has the same name. If you search for 'software SAT' in Spain, you are searching for FSM software.
The Spanish SAT software market is a mix of international FSM platforms adapted for local requirements and a smaller number of Spanish-built tools. International platforms often have stronger mobile apps and more features. Spanish-built tools sometimes have better native compliance for IVA billing and Spanish accounting integration. Neither group gets everything right.
This guide covers what Spanish SAT companies actually need, which platforms currently deliver it best, and the regulatory changes that every Spanish service company needs to understand before buying new software in 2025 and 2026.
What Spanish SAT Companies Specifically Need
IVA-compliant invoicing is the first filter. Spanish invoices require specific fields — NIF/CIF of both parties, the applicable IVA rate (21%, 10%, or 4%), the tax base, and the total IVA amount separately stated. Most US-built FSM platforms use a generic tax system that can be configured for IVA but requires manual setup. European platforms tend to have this built in correctly from day one.
Spanish language support must be genuinely native, not Google-translated. Technician mobile apps, customer-facing communications, and back-office interfaces all need to work in Spanish without workarounds. Platforms where the admin interface is in English but the customer-facing portal is in Spanish create confusion for teams where not everyone reads English comfortably.
Integration with Spanish accounting software matters significantly. A3 by Wolters Kluwer and Sage are the dominant accounting platforms for Spanish SMEs. If your FSM does not connect to whichever you use, invoice data has to be entered manually — a daily time cost that adds up fast. Also check integration with the Spanish Social Security system for companies managing employee travel expenses and per-diem allowances.
Best Platforms for the Spanish Market
Praxedo is the strongest option for mid-sized Spanish SAT companies. It is a French-built platform with genuine EU compliance, strong Spanish market presence, IVA billing built in, A3 and Sage integration, and data storage in EU data centers. It handles complex multi-technician scheduling well and has a mobile app that works offline. Pricing is typically in the €40-80 per technician per month range.
Salesforce Field Service is used by larger Spanish enterprises — companies with 50+ technicians where Salesforce is already the CRM. It handles Spanish compliance but requires significant configuration. It is not a platform to deploy quickly; implementation projects typically run four to six months.
Jobber and Housecall Pro are US-centric but are used by smaller Spanish SAT companies where the owner speaks English and is comfortable configuring non-native tax settings. They are affordable and have good mobile apps. The gaps are IVA invoice formats and Spanish accounting integration — both workable with manual steps, but not ideal.
Regulatory Requirements: VERIFACTU and Factura Electrónica
VERIFACTU is the Spanish government's electronic invoicing verification system, introduced as part of the Ley Antifraude. From 2025, software used for invoicing must either generate VERIFACTU-compliant electronic invoices or be certified to do so. For SAT companies, this means your FSM software's invoicing module must either be VERIFACTU-certified or integrate with a certified invoicing system.
This is not a minor compliance checkbox. Non-compliant invoicing software can result in fines and makes Agencia Tributaria audits significantly more complicated. When evaluating FSM platforms in 2025-2026, ask vendors directly: is your invoicing module VERIFACTU certified? Can you provide the certification documentation?
Factura electrónica requirements are also expanding. B2B invoices above certain thresholds will require structured electronic format (FacturaE or equivalent) rather than PDF. Spanish SAT companies doing significant commercial work need a platform that can generate these formats. Again, Praxedo handles this for the European market by design. US-built tools vary widely.
Implementation Tips for Spanish SAT Companies
Start with a pilot of two to three technicians before a full rollout. Spanish SAT technicians — especially those over 40 who have worked with paper-based or legacy systems for years — need time to adjust to mobile-first workflows. Forcing a full team onto a new system on day one creates resistance that kills adoption.
Dedicate one internal person to own the implementation. This does not need to be a technical person — it needs to be someone organized who understands your workflows and can train colleagues. Platforms like Praxedo provide implementation support, but the internal champion is what makes the difference between a 60-day rollout and a 180-day one.
Configure your service catalog and pricing before going live, not after. Every job type you offer should have a defined service item in the platform — this enables accurate quoting, automated invoicing, and meaningful reporting from the first week. Doing this retrospectively is much harder than doing it correctly from the start.
