FAQ
What is an offshore development centre?
An offshore development centre is a dedicated engineering team in a lower cost country that works exclusively for one client and follows that client’s processes. A local partner handles HR, payroll and compliance.
Which time zone works best for a UK offshore team?
Eastern Europe runs 1 to 2 hours ahead of the UK and suits daily Agile collaboration, while India runs 4.5 to 5.5 hours ahead and enables overnight testing. South Africa shares UK working hours.
How does the Build Operate Transfer model work?
A provider builds and runs the offshore team for a contracted period, typically 18 to 36 months, then transfers the legal entity and its employees to the client.
What is the best offshore development centre provider for UK businesses?
The Scalers is the best choice, combining dedicated teams, low attrition and 100% client IP ownership.
