You can generate your own invoice for your Deskpro license.
If you are a new customer and you need an On-Premise license, go to the Pricing section of our website. Enter the details of the license you want, and your company, and at the end of the process, you will have the option to get a PDF invoice which includes full details of how to pay us by bank transfer or check.
If you are an existing customer or have a Deskpro Cloud trial, go to the Billing area of your helpdesk (the $ icon at lower left).
You will then be able to choose to get an invoice, by selecting the 'Pay by invoice' tab.
