Free Cardlock Invoicing.

Manage Petro’s smart CardLock automated invoicing module allows you to create a client’s individual or periodic invoices in less than a minute.

Our Module can breakdown data of margins, fees, rack price, taxes, pricing model by location, sites, multi pricing models, date range, unit, fuel type, consumption, equipment type and regions. It’s all in the system and invoices are generated for you in a single click.


Manage Petro’s invoicing module handles all your pricing requirements.

You don’t have to worry about complex taxation, price structures or the pains taking time it takes to conciliate hundreds to thousands CardLock transactions every month anymore.

You can even choose to give access to your clients to log into the system to see only their company’s status of delivery, invoices, and payments. You have full control of what your clients can access because you set up all the permissions.
