Product Subscription

Here's how to simply add the order product/subscription flow in NexLvL CRM.

Order Product/Subscription

Make sure that you will only use this flow for additional product subscription aside from what was paid from the purchase form.

This is where you will choose how the payment will work for this flow.

This are the payment options to choose from.

Don't forget to hit save when you're done.
