When I send a customer invoice through the backend it would appear that he cannot use Shop to make the payment.
Topic summary
A merchant has identified a limitation when sending invoices through Shopify’s backend administration panel. Customers receiving these invoices cannot complete payment using the Shop app.
The merchant has acknowledged this as a missing feature and expressed hope that Shopify’s development team will add Shop app payment support for backend-generated invoices in the future.
This remains an open issue with no current workaround or resolution provided.
Hi Litpepro
Thank you. Hope the dev team will add the feature
