Here you enter if the user should be allowed to authorize up to a certain amount. This specified amount refers to the amount on the invoice, excluding VAT, in the system currency. If the user approves/authorizes an invoice with an amount which is larger than the purchase limit, then the invoice will automatically be sent on to the head signer entered here. If the invoice is linked to an authorization list the invoice will be sent to the head signer before it is forwarded to the next person on the authorization list.
