Business in Lisbon
Since the mid-2010s, shared-service and technology centres for groups such as BNP Paribas, Mercedes-Benz and Cisco have joined a large start-up scene in Lisbon. The capital also holds the head offices of EDP, Galp, Caixa Geral de Depósitos and Millennium bcp, while tourism, the port and government employ many more people.
Also known as Lisboa.
Where software helps: Portuguese law requires certified invoicing software, SAF-T exports and QR-coded invoices with ATCUD codes, so Lisbon start-ups and service centres billing EU clients need systems built for local rules and cross-border VAT.

05 — FAQ
Custom software in Lisbon: common questions
Do you build custom ERP and AI software for businesses in Lisbon?
Yes, remotely. Flip Retail is a software studio in Jaipur, India, with no office in Lisbon; discovery happens on video calls and you get working software every two weeks.
How do time zones work between Lisbon and Jaipur?
Jaipur is 5 h 30 min ahead of Lisbon on standard time, and 4 h 30 min ahead during daylight saving time there. A 09:00 start there is 14:30 in Jaipur. Standard 09:00–18:00 office days overlap by 3 h 30 min to 4 h 30 min, which is enough for live calls, demos and same-day answers.
Can your AI agents talk to customers in Portuguese and English?
Yes. Current language models handle Portuguese 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 hospitality business?
Usually one module that fixes the most expensive problem first. For tourism & hospitality that is often recipe costing & kitchen inventory and multi-outlet procurement. It goes live early, and the rest of the system follows in two-week increments while your team is already using it.
