For the POS Integrations that calculate the final cost on the POS there is the ability to set a % above the total that is calculated on OrderCloud so the pre-authorization will be more. This is done in case the POS has a different item amount or tax rounding amount. If a final cost is more then the pre-auth amount the order will not integrate.
NOTE: Because some credit card issuing banks keep pre-authorizations on hold and if the final amount of the completed charge is different the customer may see two separate amounts on their account. The pre-authorization will be removed from the customers account, the timing is based on the issuing bank though.
To edit the Pre-authorization %
