Advise on contracting via another ltd company

[Eirikur]

Apart from payment terms is there anything else I should be aware of?
Anything to cause problems.

Yes insolvency of the other ltd company can cause major problems. Credit check the other ltd before even starting to talk about payment terms. They may be on 90 days payment terms with the end client you should never accept that, the worse their credit score the quicker you need your money.
Get a clear SOW with well defined deliverables

Yes and even from a client perspective its not a good idea. Yes they may save money but if I left then how long would it take other person to find replacement.

Not your concern.

You have to do what's best for you - they are doing what's best for them. As I said, if hey have to use an invoice factoring company to get you on to weekly pay, you'd probably have to accept a lower rate but at least you're actively mitigating the risk. That's no different to what most agencies anyway.
