Frequently Asked Questions

How long does a typical project take?
Most custom systems launch in 4–8 weeks, depending on scope. TradeFlow365, our most recent ERP, went from contract to production in about 4 weeks — full inventory, sales and operations on AWS, web and mobile.
Do you work with companies outside the UK?
Yes. We serve clients in both the UK and South Korea with full bilingual support in English and Korean — contracts, requirements, code reviews and post-launch support all available in either language.
What technologies do you build with?
We focus on AWS serverless (Lambda, API Gateway, DynamoDB, RDS) for the backend and Flutter for cross-platform front-ends. We pick proven, boring technology that ages well and keeps running costs predictable.
Do you offer ongoing support after launch?
Yes. Once a system is live we keep it healthy with monitoring, bug fixes and regular feature releases. Most clients move into a long-term partnership rather than a one-off delivery.
Can you take over an existing system?
Often, yes. We've migrated clients off spreadsheets, legacy desktop apps and outdated SaaS into purpose-built systems they actually own — with their data exported and the new platform under their AWS account.
