Our website is using manual payment method (bank transfer) which made the payment status has to be changed manually to "Paid" after customers made the bank transfer.
The problem is that many customers seem to forget to do the bank transfer and we are searching for a way to follow up on this via SMS automatically. Email is not an option since not everyone is using email to sign up.
Is there any app which allows SMS follow up on pending payments? All of the SMS app I found on Shopify store are only offering options for abandoned checkout, meanwhile in our case the checkout is done but the payment is pending.
It will be better if the app allows custom SMS gateway because some mobile operators in my country have problems receiving SMS from abroad.
Arigato can do all of this. https://apps.shopify.com/mr-arigato-task-automator
For the gateway, you can connect your own Twilio account.
