We can improve your cardlock invoicing process.

TEI takes care of your cardlock transactions, along with the rest of your fuel, propane or lubricant delivery business data. TEI imports cardlock files from all your vendors. By importing transactions, you can automatically generate invoices and optionally send them to clients. The profit margins, fees, purchase prices and cardlock identification numbers all are set up in each customer’s profile. 

Importing Transactions

Creating invoices

Company setup

TEI is many systems in one, making your entire operation efficient and paperless: we provide ordering, dispatching, delivery, invoicing, bookkeeping, and payment collection—all in one powerful tool.

A real-time connection like TEI’s doesn’t have to wait for drivers to come back to the office to finalize the clients’ invoicing. It receives all delivery details the moment it’s completed. Invoices sent out automatically, so you get paid faster.

Business sales process

TEI keeps track of all your transactions and sends you and your clients reminders and notifications to keep you up to date with live, real time data and continuous communication between your drivers, work orders, customers, and so much more.
