Shopify sends confirmation emails for manual orders, as such, you can customize the order confirmation template to avoid customer confusion. Watch the video below to learn the amendment steps.
PROS: If your client abandons the checkout page before completing the order, they can click the link in their email to resume the checkout process via Social Pay. Social Pay also sends a confirmation email to you and your client for each transaction.
CONS: If you have additional gateways, such as paypal, it may also be confusing to your client as paypal doesnt trigger the order email until the payment is completed. However, the client should also receive a follow-up email from your gateway provider in a similar fashion like Social Pay.
