1 | # WHMCS-Product-Limiter
2 |
3 | WHMCS Product Limiter is a free addon module that gives you the ability to limit purchasing a product to specified times (adjustable).
4 |
5 | When activated, once the client will try to purchase the same product again – he will receive an error message (customizable)
6 |
7 | That can be handy when giving free trial versions.
8 | This module will help you to stop free trial versions abuse, as the client will not be able to download more then once product.
9 |
10 | # Installation
11 |
12 | Upload the folder "limit_purchase" (as is) to your WHMCS installtion.
13 | After uploaded, the full path to the module should be: “modules/addons/limit_purchase“.
14 |
15 | Login to your WHMCS as admin user, and navigate to “Setup” -> “Addon modules“.
16 |
17 | in the “WHMCS Product limter” module, and activate it.
18 |
19 | Now go back to “WHMCS Product limiter”, click “Configure” to add Access Control to admin groups.
20 | Save your changes and your module is all set.
21 |
22 | You will be able to access it throught the “Addons” top menu.
