Thanks, Jan")* Hi, Well, it's possible to override the whole function with a system plugin implementing a function of the same name. However, I would rather recommend you do a normal plugin of the group "hikashop" and implement the onBeforeOrderNumberGenerate(&$data, &$result) and / or the onBeforeInvoiceNumberGenerate(&$data, &$result) events. In $data, you'll have the information of the order and you can just set in $result whatever you want and it will become the order / invoice number. If you want to know how to make a plugin, you can read the two first parts of the page [ www.hikashop.com/support/documentation/6...mentation.html#intro](https://www.hikashop.com/support/documentation/62-hikashop-developer-documentation.html#intro) and use the link to the Joomla documentation which goes in depth about creating plugins for Joomla.

Thanks, Jan")* Hi, Joomla is based on the MVC model ( [ en.wikipedia.org/wiki/Model%E2%80%93view%E2%80%93controller](https://en.wikipedia.org/wiki/Model%E2%80%93view%E2%80%93controller) ). And HikaShop too. So in HikaShop's folder, you'll find "classes" which is for the models, "controllers", for the controllers and "views" for the views. The "helpers" folder contains files with helpers that can be used by the MVC elements which aren't tied to one view, one controller or one model. For example the "translation" helper has functions that are used by the views and controllers to manage the translations of the content.
