There are plenty of stuff that does not work as a small company. You know the easy way that large companies balance their cashflow between countries selling IP and stuff. Try that as a small company (eg: make money in the UK, try to hire some guy in Spain to build an app there, i.e. a genuine case of actual workflow issues) and realise that you can only charge for actual service and yes you can in theory have vague service like "consulting" but in reality if the tax office take an interest in your company you are going to be crucified. Cashflow balancing is corporate taxed both ways, better get it right.
