01 — Local economy

Business in Irvine, CA

Edwards Lifesciences and Masimo make Irvine a medical-device centre, and their growth has drawn contract manufacturers, regulatory consultants and component suppliers to the Irvine Spectrum area. The city is also home to Blizzard Entertainment and the US headquarters of Kia and Mazda, while its master-planned business parks, developed largely by the Irvine Company, house finance, mortgage and software firms.

Where software helps: Medical-device makers and their suppliers here must keep FDA device history records, UDI labelling and lot traceability tied to production and complaint handling, which disconnected spreadsheets cannot reliably support during audits.

05 — FAQ

Custom software in Irvine, CA: common questions

Do you build custom ERP and AI software for businesses in Irvine, CA?

Yes, remotely. Flip Retail is a software studio in Jaipur, India, with no office in Irvine; discovery happens on video calls and you get working software every two weeks.

How do time zones work between Irvine, CA and Jaipur?

Jaipur is 13 h 30 min ahead of Irvine, CA on standard time, and 12 h 30 min ahead during daylight saving time there. A 09:00 start there is 22:30 in Jaipur. Office hours don't overlap, so we fix one call slot at the edge of the day and work asynchronously in between.

Can a custom ERP handle California sales tax?

Yes. Invoicing handles California sales tax (7.25% statewide base rate (including 1.25% mandatory local) plus local district taxes) and the other states where you have nexus. If you or your customers want it, a custom ERP can connect to DBNAlliance through an accredited provider.

Can your AI agents talk to customers in English, Chinese and Korean?

Yes. Current language models handle English, Chinese and Korean 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 pharma business?

Usually one module that fixes the most expensive problem first. For pharma & life sciences that is often batch & expiry control and formula and recipe management. It goes live early, and the rest of the system follows in two-week increments while your team is already using it.
