Overview
Feature Description
The Commercial Fleet feature supports commercial payment card programs accepted at sites and also allows dispensing of multiple fuel products in the same transaction.
Commercial fleet transactions can be performed at commercial DCRs with alphanumeric keypads or inside as a prepay or postpay sale. Inside prepay sales do not require an an amount to be entered for the pre-authorization.
You will be able to designate fueling positions as ‘Commercial’ via Configuration Client. For those fueling positions, you can:
Create and assign secondary fuel products that roll up to a primary product (e.g. Primary=Diesel, Secondary=Tractor, Reefer)
Enable a fueling position to dispense multiple products in a single transaction
Your VASC will work with you to make sure settings are correct and according to your site’s products and preferences.
Main Highlights
Commercial Fleet customers may be eligible to request cash advances. Cash advance settings are managed by the site and fleet manager. The cash advance that appears to the customer is the lowest one. Cash advance is only given after fueling.
Customers can pay and cash fleet checks at sites that accept them. Fleet check can be used in split tender transactions with cash. For further details view “Configuring Fleet_Check MOP” and “Fleet Check Transaction”.
Prepay inside requires the new “Commfleet Prepay” button to be configured for non-commercial dispensers. For further details view “Assigning Electronic Void and ComFleet Prepay functions to Soft Keys”.
Postpay transactions work without any configuration, assuming the site chooses to authorize pumps.
Other Highlights
If the site DCR does not have alphanumeric capability or if the DCR has alphanumeric capability but is not enabled for alphanumeric input, the customer will be sent inside to enter details as prompted. For further details view “Enabling and Assigning Alphanumeric DCR Keys”.
Comdata Cards
Supported and Unsupported Features
The following are the supported and unsupported features for Comdata Fleet Cards:
Cash Advance is supported with the Comdata transactions.
Multigrade fuel selection is supported with Comdata transactions.
Mix of Comdata and non-Comdata products are not allowed while using Comdata Cards. Cashier will be asked to remove non-Comdata products from the ticket.
Refund is not supported for Comdata transactions.
Offline transactions (aka SAF) is not supported for Comdata transactions.
Comdata transactions at the DCR will not prompt if the customer wants to add additional products inside after fueling.
Only Comdata eligible products can be sold on Comdata network.
Car Wash, Charity and loyalty/discounts are not supported with Comdata transactions.
Split tender is not supported for Comdata transactions. Comdata eligible products can be bought using other cards, which do allow split tender.
Electronic Void (E-void)
Transaction type Refund is not supported for Comdata cards and instead of a Refund request an E-void request is sent to the host to void transactions that must be refunded. E-Void is not supported for fuel transactions and for any transactions not done on the same day.
E-void for Comdata cards works the same way as it works for Exxon's FleetOne card and the Wex Commercial Fleet cards. Refer to “Assigning Electronic Void and ComFleet Prepay functions to Soft Keys” and “Electronic Void Refund Transaction”.
Comchek
Comdata issues a check which is known as Comchek. Comcheks can be used as a usual physical check at stores, or the unique 10-digit Comchek number can be used at stores. There is no product restriction for Comchek. Comchek can be used to buy any product available at the store. Comcheks can also be cashed without buying any product.
Express Code
Express code is a numeric code issued by Comdata that the drivers get through their Comdata app. Express Codes can used to buy products at the store.
There is no product restriction for Express Codes and can be used to buy any product available at the store.
Fuel Price Update
This feature gives the ability to send diesel fuel price changes at the site to the Comdata host. The diesel price is sent to the Comdata host so that Comdata can advertise the price on their mobile app that drivers use when looking to refuel. They also use the price when transactions are performed to ensure that the price sold at the site is within a tolerance of the price advertised on the mobile app.
Fuel price updates are sent to the host for fuel products that have fuel grade id same at both the Buypass Configuration page and the Fuel Product settings page.
Only the Self fuel price update for cash and credit are sent to the host and not fuel price updates for Mini and Full.
If the site updates the fuel price when Comdata host is offline, then the updates are stored, and the update is forwarded when the host comes online.
Dynamic Prompts
Dynamic prompts are the prompts that are sent by the host based on the card used. Comdata Transactions supports a total of 14 dynamic prompts. Fiserv supports up to total of 8 prompts (both dynamic and system) in a single transaction.
Some of the dynamic prompts are optional. Press OK without entering anything for skipping optional prompts. If mandatory prompts are skipped thrice, then the transaction is declined.
There is no way other than through experience that a cashier or a customer would know which is an optional prompt.

To enable to fuel a primary product as a secondary product with a different name, configure Secondary Products from Configuration Client > Forecourt > Fuel Config > Fuel Productstab.
For Example, Tractor and Reefer are dispensed from the diesel hose and is Diesel but named as Tractor and Reefer.
Tank and Price for the secondary products is same as Primary product. Secondary Product has its own product code.
The advantage of using the primary product as a secondary product with a different name is that the product when used as a secondary product can save tax or/and can be eligible for a discount.
Enable Secondary Product
In the Name feild, enter a name for the secondary product. The name given for the fuel product in this field is what is displayed to the customer and cashier, so choose name appropriately.
From the Primary Product drop-down list, select the primary product that is used as the secondary product.
Click Save.
Configuring Fuel Product as Only Primary Products
Sites can also be setup as a single hose/single product commercial fueling position. For example sites can have a configuration for selling just Diesel, if they do not want to configure Tractor or Reefer as secondary products of Diesel.
The secondary product field should not be enabled in Configuration Client > Forecourt > Fuel Config > Fuel Products tab.
Enable Commercialin Configuration Client > Forecourt > Fuel Config > Fueling Positionstab. For single hose fueling stations, only one hose should be configured in Configuration Client > Forecourt > Fuel Config > Fueling Positions tab.
