just had a new child start with me. contract completed and signed, the payment due date is 25th each month but as already gone I explained and have them am invoice confirming payment due immediately. this was last week. when I checked bank I realised they had not paid, I asked them and they said they thought it was the 25th this month, I had explained clearly and in writing. they agreed to pay that day, that was 3 days ago. just checked and still not paid its over a week late now. in my contact I have late payment fee after a week. I will speak to them tomorrow and chase payment again. it doesn't seem right to me, they knew it was in advance. I am wondering whether to charge late fee but don't want to cause bad feeling with a new starter. at same time don't want to be taken advantage of.
