After using WP Simple Pay Pro for a while, you may find that you need to upgrade your license for more sites or to add Stripe subscription capabilities, such as from Personal to Business.
We’ve made it easy to upgrade by paying just the difference in price and keeping your existing license key.
First, log in to your WP Simple Pay account. Under your license information click Upgrade Now.
On the next page, you’ll be presented with upgrade options along with the price. Since your annual renewal date will remain the same (a year from the original purchase), the cost will be prorated accordingly.
After clicking Upgrade License for the plan you’re looking for, you’ll be taken to checkout to complete the purchase.
At this point, you should be able to activate WP Simple Pay Pro on additional WordPress sites and access additional features in the settings without changing your license key. If you have any issues with the license upgrade process please submit a support request.
