Re: How to make a big company pay their debts on time
…sending a statutory demand to the likes of BT is not unreasonable. The idea is to get the attention of people who can actually make things move
If your business is about to fail due to poor cash flow due to a single large client like BT paying late, then sure, hassling them with every legal avenue at your disposal is useful. However, if you are doing 'ok', then I wouldn't bother hassling BT immediately. A company like BT will always pay a valid invoice, and having you scamper around trying all kinds of tricks to get payment is counter-productive to actually running your business.
If you have a choice of spending the day getting new business, or spending all day chasing a client who is very likely to pay in the next 20 days anyway, chasing new business will probably pay more.
