Business in Osaka
Doshomachi, a street of medicine merchants since the Edo period, is still home to drugmakers such as Takeda and Shionogi. Panasonic, Daikin and Kubota run global businesses from the Osaka area, and neighbouring Higashiosaka holds thousands of small factories making machined parts, fasteners and tooling. The city's long role as Japan's wholesale centre survives in textile, food and hardware trading districts.
Where software helps: Small machine shops in Higashiosaka quote job by job, send parts out for plating and heat treatment, and must issue qualified invoices under Japan's invoice system to their larger customers.
Batch and expiry tracking from raw material to finished pack, formula management, QC release before dispatch, and audit trails that inspectors and customers can follow.
AI agent
A document agent that drafts batch records, certificates of analysis and customer responses from approved data, with every output reviewed by QA before it is used.
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 Osaka: common questions
Do you build custom ERP and AI software for businesses in Osaka?
Yes, remotely. Flip Retail is a software studio in Jaipur, India, with no office in Osaka; discovery happens on video calls and you get working software every two weeks.
How do time zones work between Osaka and Jaipur?
Jaipur is 3 h 30 min behind Osaka all year. A 09:00 start there is 05:30 in Jaipur. Standard 09:00–18:00 office days overlap by 5 h 30 min, which is enough for live calls, demos and same-day answers.
Can your AI agents talk to customers in Japanese and English?
Yes. Current language models handle Japanese 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 electronics business?
Usually one module that fixes the most expensive problem first. For electronics & electricals that is often bOMs with alternate parts and reel, lot & serial tracking. It goes live early, and the rest of the system follows in two-week increments while your team is already using it.
