If you’re selling B2B services, anything you sell to a client based outside UK is outside the scope of UK VAT, so that simplifies that issue. I would imagine the extra headache of routing funds through multiple entities is unlikely to be worth it, unless clients in the USA/Australia are making you jump through hoops, repeatedly, to prove your tax status?

We have (and have had) a few digital marketing clients. One was a total nomad and relocated their business to the states as most of the higher paying clients they had were based there, the rest simply bill from their UK limited company without much issue, and they have just as many high-paying clients 🤷‍♂️.

Anything you’re specifically looking to minimise/maximise about your setup?
