SPD Split Payment & Deposit

A solid alternative to the generic pre-sale apps.
This is much faster and does not require you to use a presale wizard each time you want to offer
Presales
Partial Pays
Split pays
Installment pays

For your clients.

You can choose to lump your presales into a specific collection by #tag and then you have a standardized policy for all of your presales or, you can customize product by product so that if you want some partial pay, and some all paid at once, you can specify those rules per product.

What for the life of me I cannot seem to wrap my head around is a shopify flaw.
Shopify will not allow any app extender/plug in to work with their cart.

Scenario
If you accept partial pay, regardless of anything else in the universe, Shopify robs you of the use of a discount code on that product. Period.

This is nuts if you have tiered clients! Some Retail, some wholesale, some b2b.

An additional reason this is paramount and a total lack of attention to retail is this
WE must build in fees to cover
Affirm
Shop-pay
Credit Card Fees

So by that rule the client pays a higher price regardless of which advantage they choose.
Shop pay 6%
Credit card 3%
Cash 0%
Fee based transaction are real world. Shopify is a complete fail here.

This app, imagine how robust your site would be with this app and the ability to either surcharge fee users or discount code Feeless Users?
