01 — Local economy
Business in Madrid
Corporate campuses ring the capital: Banco Santander's in Boadilla del Monte, BBVA's and Telefónica's in Las Tablas, and Repsol's in Méndez Álvaro, alongside construction groups such as ACS and Acciona. Barajas airport and logistics parks along the A-2 and A-4 motorways distribute goods across Spain, and consultancies, law firms and a sizeable start-up sector serve the head offices.
Where software helps: Spain's Verifactu rules require Madrid companies to issue tamper-proof, traceable invoices from compliant software, with a B2B e-invoicing mandate to follow, so many firms are replacing old billing tools and spreadsheets.

05 — FAQ
Custom software in Madrid: common questions
Do you build custom ERP and AI software for businesses in Madrid?
Yes, remotely. Flip Retail is a software studio in Jaipur, India, with no office in Madrid; discovery happens on video calls and you get working software every two weeks.
How do time zones work between Madrid and Jaipur?
Jaipur is 4 h 30 min ahead of Madrid on standard time, and 3 h 30 min ahead during daylight saving time there. A 09:00 start there is 13:30 in Jaipur. Standard 09:00–18:00 office days overlap by 4 h 30 min to 5 h 30 min, which is enough for live calls, demos and same-day answers.
Can your AI agents talk to customers in Spanish and English?
Yes. Current language models handle Spanish and English well, including mixed-language messages. We still test an agent in each language your customers use before it goes live, and route anything it is unsure about to your team.
What would a first project look like for a financial services business?
Usually one module that fixes the most expensive problem first. For financial services & fintech that is often onboarding & KYC workflows and loan and policy lifecycle. It goes live early, and the rest of the system follows in two-week increments while your team is already using it.
