01 — Local economy

Business in London

Wholesale banking, insurance and asset management in the City and Canary Wharf anchor the capital's economy, alongside the Lloyd's insurance market and the London Stock Exchange. Law firms, consultancies and accountancies cluster around them, fintech and software companies fill Shoreditch and King's Cross, and the West End supports theatre, retail and hospitality, while Park Royal's warehouses and food plants supply the city.

Where software helps: London firms with clients across the UK, EU and US juggle multi-currency invoicing, VAT returns under Making Tax Digital and time-based billing, often spread across several disconnected systems.

05 — FAQ

Custom software in London: common questions

Do you build custom ERP and AI software for businesses in London?

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

How do time zones work between London and Jaipur?

Jaipur is 5 h 30 min ahead of London 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.

What would a first project look like for a financial services business?

Usually one module that fixes the most expensive problem first. For financial services & fintech that is often onboarding & KYC workflows and loan and policy lifecycle. It goes live early, and the rest of the system follows in two-week increments while your team is already using it.
