To buy resources using a purchase order, please add the items to your cart and go through to check-out, where you can select 'Manual Payment'. This will prompt us to generate an invoice for your finance team to do a bank transfer. Please note, this is not instant; you will receive the invoice within 24 hours. Once the money is received, we will send the resources. Please note: we cannot edit invoices after they have gone out, so please check that details are accurate and what your school or payment facility requires from you. If you need a tax number on the invoice, add it to the address and it will appear on the invoice. If an invoice has incorrect details, we have to void it and you will need to order again.
