You can find an overview of billing after logging in to the customer administration (client.wedos.com) in the Billing -> Credit account -> Billing tab.
Each bill belongs to an invoice that contains the billed services. Finally, the relevant amount of credit is deducted from the invoice so that the total amount on the invoice is 0 CZK.
If any items that need to be billed are founf in the credit account (unbilled payments for orders that are no longer blocked, ie the service has already been set up), you can see the number of items that need to be billed and an invoice will be sent to you after clicking the create a bill button.
Billing can also be completed automatically, per each calendar month. Such billing is completed (and a final invoice is issued) during the first half of the following month. The invoice will arrive to the customer via e-mail.
