There is a factoring compnay on your door step Neil called Close Invoice Finance, give them a ring and someone will come and see you. Getting INTO factoring is easy, getting out of it is a nightmare, they are in effect loaning you money and even the your smallest companies and best payers will have to be factored.
I had a turnover over over 300k when I factored and felt like I had lost control on my business some what, the paperwork was confusing anf the company difficult to deal with. It is very expensive to get out of it. 70% is low, most factorers go to 80% easily enough and 90% at a push.
Think long and hard before you commit and feel free to email me if you want a chat. In my experience they are in no hurry to et the money in as while you owe it you are paying interest at about 1.5-2% over base rate.
On paper a good idea, the reality is a little different. I admit it did help the company to grow, but you rapidly owe a lot of money.
The banks system is....overdraft....loan......overdraft.....bigger loan....factor. You also cannot have bot a overdraft and factor at the same time, again on paper that is resonable, in reality not always possible. All banks have there own Factoring divisions, check them out before deciding if it is for you or not!!
