Tradefirst
My company has used them and I have to say I wouldn't recommend it. It is a barter system - you supply goods and services, don't get paid cash but by goods from other suppliers. The list of suppliers who have signed up is very restricted e.g there many only be one company under a classification. You are restricted to using a supplier that you would not normally use, you can't shop around for the best price, the service may not be 100%, but you are tied in to it because have the credit in the bank.
