Ukraine visa query

Hi,

We have a software developer who's worked for us for the last 12 months, he's based in the Ukraine so works completely remotely and sends us an invoice and timesheet each month.

He does a fantastic job for us so we decided it would be nice to invite him over to the UK for a weekend as a treat.

He's made some enquiries about getting a visa but its quite complicated, he spoke to someone in the Ukraine who told him its best to apply for a tourist visa and claim he is visiting friends.

But i'm not sure if a business related visa would be more appropriate.

Can anyone offer any advice on this?

To be clear he would be visiting for 2 days and there wouldn't be any kind of work involved, i.e. its purely a social visit. Also we would be covering the full cost of his trip (flights, hotel, spending money etc)

Thanks

Business visa more appropriate and more guarantees with the backing of a bobafide company, visit visas for Ukes are a bit of a lottery.
