01 — Local economy
Business in Bilbao
Iron ore from the surrounding hills and shipyards on the estuary built Bilbao's industry, and steel, forging and machine-tool firms are still spread along the Nervión valley and in nearby Gipuzkoa. Iberdrola keeps its registered head office in the city, Siemens Gamesa designs wind turbines in Zamudio, Petronor runs a refinery at Muskiz, and BBVA traces its origins to Bilbao.
Also known as Bilbo.
Where software helps: Steel, forging and machine-tool firms in Bizkaia must invoice under the province's Batuz and TicketBAI rules, which differ from Spain's Verifactu, while also tracking heat numbers and machine-build costs.
ERP and AI for steel, energy and engineering businesses in Bilbao
What we would build first for the industries Bilbao is known for.
Steel & metals
ERP
Stock by grade, size, thickness and warehouse; weight-based pricing with cutting and loading charges; part-load dispatch; and credit limits checked before an order is confirmed. This is the problem our own SteelERP product was built to solve.
AI agent
A quoting agent that reads enquiries from WhatsApp or email (“20 tonnes TMT 12 mm, delivery Thursday”), checks free stock and the day's rate, and drafts the quotation for a salesperson to send.
Project and contract costing, equipment and spares across sites, maintenance schedules, and compliance records for contractors and service companies in the energy supply chain.
AI agent
A field-service agent that turns technicians' voice notes and photos into job reports, updates the asset history and raises spare-part requests.
Make-to-order and engineer-to-order projects tracked from enquiry to commissioning, with multi-level bills of materials, drawing revisions, subcontracted machining and spare-parts sales in one system.
AI agent
A spares assistant that identifies parts from a photo or serial number, checks stock and price, and answers dealer and customer queries on WhatsApp or email.

05 — FAQ
Custom software in Bilbao: common questions
Do you build custom ERP and AI software for businesses in Bilbao?
Yes, remotely. Flip Retail is a software studio in Jaipur, India, with no office in Bilbao; discovery happens on video calls and you get working software every two weeks.
How do time zones work between Bilbao and Jaipur?
Jaipur is 4 h 30 min ahead of Bilbao 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, Basque and English?
For Spanish and English, yes: current language models handle them well, including mixed-language messages. Support for Basque is more limited, so we test with real customer messages before committing to it, and route anything the agent is unsure about to your team.
What would a first project look like for a steel business?
Usually one module that fixes the most expensive problem first. For steel & metals that is often grade, size and location-wise stock and weight-based rates & price lists. It goes live early, and the rest of the system follows in two-week increments while your team is already using it.
