We offer two kinds of Partial Pre-orders and they are:
1. Purchase option method.
2. Legacy method.
Purchase option method
This method benefits from Shopify's API and hence, it's only supported on the following payment gateways:
1. Paypal payments gateway.
2. Shopify payments.
But a very big plus side is, that once the user has given you the credit card information with your initial deposit amount, the other half of the amount or balance payment will be charged automatically on the specified date.
Legacy method:
With this method, our app splits your order into two portions, both with adjusted prices so that the first order is to be paid as the initial amount and the other one is the balance amount of the pre-order. Once done, and completed the payment of the first order, the customer is sent a link to 2nd part of the payment and he must save it and complete it as per his comfort or your recommendation.
We can't send this link again so user needs to make sure they save the link. Once paid, you can fulfil this order.
