Order totals extensions

You can manage the order total extensions used for orders under Extensions > Order Totals. These totals are extra fees that are added to the total sum of an order in the store's shopping cart. For more information on order totals, visit Orders. The order total extensions below are included with the StoreMantis package.

In the image above we can see that Coupon, Store Credit, Reward Points, Shipping, Sub-Total, Taxes, Total, and Gift Voucher extensions are enabled. These enabled order totals will be included in the checkout section. If you want to remove an extension, click "Uninstall".


Coupons can be added to the order totals page by selecting "Enabled" under "Status". The sorting order affects the order that the extension is put in.

Store credit
