Nick here from Shopify. ?
This is a great question, but currently not something which would be possible to do on the Shopify platform right now. Could elaborate a little bit about why you would want this, and how it would benefit you or make your life easier while selling? I could then pass this back to the payments team for future consideration on your behalf.
We would also like this option. Or an option to send invoices on certain products rather than take payment immediately, but only on certain products. I've literally just done research to consider transferring my shop from Squarespace to Shopify if this was an option but unfortunately it seems like it's not possible on Shopify either.
I know it's possible with 3rd party apps because I am able to restrict payment gateways for usage with store credit in rewardify. Another reason this is very much needed in my instance - is in regard to clearance or items you're offering at lowest prices (stale inventory etc). It's hard to justify paying a 6% transaction fee with gateways such as Sezzle on items marked down so low. So, I am specifically looking for this option as well. I would love to run a recurring daily deal, but I do not want to allow sezzle as a payment option on these lower priced items.
