Extensions & Modules

CLICK HERE To view a DEMO on our DEMO Website. Not all extensions have a demo.

SPECIAL NOTE: All of our extensions are for OpenCart - All previous versions of OpenCart have been rendered useless with the implementation of PHP 8.xx and OpenCart 4.xx. We have available a version of OpenCart - that works with all PHP 8.xx versions. If you would like to upgrade your OpenCart store to this version, please use our upgrade service. We will implement the upgrade and in most cases your customer and order data will be preserved. The new OpenCart 4.xx versions have completely rendered all previous versions of OpenCart extensions useless. Until a time that we can upgrade (complete re-write) our extensions, we will focus our energy on OpenCart - which we feel is the best OpenCart version to date.

The Net 30 Payment Gateway allows you to give your customers the option during the checkout process to pay the invoice in 30 days. The extension is a great tool for Brick and Mortar stores that have a web presence as well as a physical storefront or any other type of manufacturing facility. Some customers have issue with giving their payment information to a computer/internet.

Net 30 will give the store owners one more tool in their arsenal for making sales. You can give your customers any message you wish. After a Net 30 sale has been made, the admin order total goes to red notifying store owner that a Net 30 sale is pending. After the payment has be processed and store owner changes the order status from a Net 30 status to any other status, the order total goes back to black. New added feature, now works with guest checkout.

Features include:

✔ Extension is treated as a payment option allowing it to work with any theme.

✔ Guest checkout option.

✔ Store owner has complete control of the message the wish to give their customers.

✔ When a sale has been made the admin order total turns red until store owner verifies payment.

✔ Customers emailed invoice will also reflect that a Net 30 sale is not complete until they make contact with store/owner. Store owner has complete control of the message.

✔ The extension automatically adds a new order status called Net 30.

✔ FREE BASIC INSTALLATION (within 5 days from the date of purchase)
