Outstanding invoice question, please help!!!?

Posted at: 2014-12-08 
There is NO legal 60 days in the UK. You are supposed to pay the invoice as soon as you receive it, or you can accrue interest.

Do you have anything in writing about their terms for payment?

UK

You don't "get" 60 days to pay an invoice.

My invoices are due upon receipt.

What terms did you sign up for when you agreed the goods or services?

I received a letter today from a credit management company asking for £50 for outstanding invoice to a company. The company never send any letters prior to this but the problem is that on top of £50 this credit management company is asking for £40 as a late payment fee so amount to pay in letter it says £90 but when reading the letter it states: 'the breakdown attached confirms the potential late payment costs you may incur if payment is not received within terms and we have to write to you again' ?? so does this mean i have to pay £90 because it clearly says in their letter that its a potential late payment cost and i may incur it but still they want £90 in total and in breakdown it says amount due £90 and then below it states the late payment fee and interest which says £40. The amount i owe company is obviously £50 and other thing is that the company i owe this money to 'sent' a invoice to me on 19th sept which i never got but its not even been 30 days and they passed it straight onto credit management company who want extra £40 , any advice would be great! thanks!
