One set of parents pays partly with childcare vouchers and partly by direct bank transfer. The transfer (about 60% of the fee) went in on the last day of last month as it was supposed to but the childcare voucher didn't appear until today - three days late. I would assume the parents tell the voucher people when to pay and probably have to allow a certain number of working days, which I guess they didn't do. Would you make a charge for this? My contract says £5 per day for late payment.
