Hello,
May I know what subscription payment methods are implemented?
Is it native payment or any payment gateway?
Yes there are always notifications, to vendors and customers both.
Unfortunately we do not consult, but can review the current app, and create a functionality if anything is missing.
Having said that, in case your apps are in under development, we can do it for you with all payments terms and conditions for different use cases, fix notifications and provide insights if required.
Let me know if we can help?
Thank you.
