Product Fee Instructions


Be sure to ALWAYS backup your database and store files before installing ANY extension.

1) Go to Extension>Installer. Upload the .ocmod zip file then press the refresh button on the Modifications page.


  1. In your admin go to Extensions | Order Total | Find One Time Setup Fee and click install. Then edit the extension to enable it. Set the sort order to at least 4.
  2. Go to the Product Edit form, select a product and add a fee.


To use the extension go to each product that will have a setup fee and fill in the details. Be sure to save after editing. The One Time Product Fee will show on the product page and during the final step of the checkout process.



In order for the extension to calculate taxes correctly you have to set the sort order to a number LOWER than the Tax order total or it will not calculate taxes.

  1. Go to Extensions, Order Totals
  2. Click Edit for One Time Setup fee (take note of the sort order for the Tax order total)
  3. Enter a sort order LOWER than the Tax order total noted in step 2

If you have any questions about the installation process or how to use the extension please contact us.
