01 — Local economy
Business in Lille
Several of France's biggest retailers grew out of the Mulliez family businesses around Lille, and Decathlon, Auchan, Leroy Merlin and Kiabi still run their head offices in the metropolitan area. Former textile mills in Roubaix and Tourcoing now house mail-order and digital firms such as La Redoute, and the location between Paris, London and Brussels supports large distribution and logistics sites.
Also known as Rijsel.
Where software helps: Retailers and e-commerce suppliers around Lille sell into France, Belgium and the UK, which means multi-country VAT, post-Brexit customs and returns flows that ERP and order systems must handle without manual rework.
ERP and AI for retail, logistics and textile businesses in Lille
What we would build first for the industries Lille is known for.
Retail & e-commerce
ERP
One stock position across stores, warehouse and online marketplaces, with purchase planning, store transfers and point-of-sale billing tied to the same item master.
AI agent
A customer-service agent that answers “where is my order”, handles returns and recommends products, and passes complex cases to a person.
Shipment and job costing, warehouse management with bin locations, customs and freight documentation, and billing that captures every accessorial charge.
AI agent
A document agent that reads bills of lading, commercial invoices and packing lists, extracts the data and pre-fills customs and booking forms for review.
Style, colour and size matrices; yarn-to-fabric-to-garment process tracking across job-workers; and order-wise costing that includes dyeing, printing and embroidery charges.
AI agent
An agent that reads buyer tech packs and purchase orders, builds the costing sheet and material requirement, and flags anything missing before sampling starts.

05 — FAQ
Custom software in Lille: common questions
Do you build custom ERP and AI software for businesses in Lille?
Yes, remotely. Flip Retail is a software studio in Jaipur, India, with no office in Lille; discovery happens on video calls and you get working software every two weeks.
How do time zones work between Lille and Jaipur?
Jaipur is 4 h 30 min ahead of Lille 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 French, English and Dutch?
Yes. Current language models handle French, English and Dutch 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 retail business?
Usually one module that fixes the most expensive problem first. For retail & e-commerce that is often point-of-sale billing and omnichannel inventory. It goes live early, and the rest of the system follows in two-week increments while your team is already using it.
