Im invoicing my mindees mum she has given notice of change of hours.Ive been unable to invoice her for about 2 weeks but a friend said email her instead as my printer is broken.How do l invoice her over the weeks shes not using as shes started her new hours already.I thought of comfiming the notice through an email but am not sure about the invoice do l put down the hours she nomally uses or just the ones shes using now

What date did she give you for wanting to change to new hours? Invoice old hours up to this date and then the new hours from that date. Also you should be doing a new contract if hours have changed.
