Uploading invoice templates

To speed up the connection process, please upload your previously issued standard and credit invoice for the connection project, or any invoice type that you have marked in the Checklist.

This is necessary so that our testing colleagues can prepare a template that is tailored to your account. These invoices are used exclusively for the purpose of the test process, i.e. they are not productively processed, booked, or paid.

For testing real data content is required, therefore we expect sample invoices that you have already sent to the partner you want to send invoices to in the future.
