Type of payments
Add your own type of payment which you will most frequently use. The only default item is "Send the invoices via the surface mail", which cannot be removed, you can, however, set your own price.
Due to the individual work with a higher number of the clients to be sent a message, this process becomes more costly as well as time demanding. You can thus charge this process. The price 5CZK is rather esthetic, 40CZK is motivational for the transition to having the option of sending the invoices via e-mails.
By higher price you can cut down on those clients who wish their invoices to be sent via the surface mail. In case of companies who have to have this like that, you can set an individual price while adding a service, ie. lower or no price for sending invoices.
