Pre-Order with a specific Selling Plan for a customer

[eliascassis]

Hi everyone!

I need to apply a Selling Plan for a specific customer. The flow I'm thinking is depicted below - considering a single item for purchase:

1. The customer clicks in the button to buy a product
2. Using the GraphQL API the app will create a Selling Plan attaching the selected product and adjusting the price for the customer wanting to purchase it
3. On checkout, the customer can see the new price calculated for the item

The adjusted price needs to be calculated prior the creation of the Selling Plan and is specific for the customer. 

I need to create a Selling Plan for a single item and with its price adjusted for a specific customer.

Is there any way of achieving this behavior? 

I want to use the Pre-Order category of the Sellin Plan Group to benefit of its features but I couldn't find a way of doing it in the Shopify Pre-order and Selling Plan API docs. 
Using automatic discounts and Shopify Functions would be the best way to go?

Hey Elia,

I asked my technical co-founders about your scenario and they don't think creating a selling plan per customer would be a good idea.

A discount code as you've suggested, would be much easier. 

If you want to generate it live, have you looked into using the API to create a code for each customer when they go to purchase?

What are your other requirements? We run a pre-order and partial pay app, and I'm always looking to understand the different pre-order edge cases out there. (E.g. Is this for wholesale?)

Hi Jo,

Thank you for your time in answering the question.

Yes. Currently I'm using the API to apply a discount for the customer on checkout.

I was just exploring the capabilities of the Sales Plan API and thought it could be an alternative to change the price of merchandise at checkout for each customer.
