This module increases your card-lock invoicing performance.

Manage Petro migrates your card-lock transactions along with the rest of your fuel, propane or lubricant delivery business data.

Manage Petro imports Card-lock files from all your vendors. By importing transactions you can automatically generate invoices and send them to clients (optional). The profit margins, fees, purchase prices and card-lock ID numbers all are set up in each customer’s profile in advance.

You can create invoices directly from Card-Lock transactions in just one click.
