Hi,
Very few HikaShop plugin have such feature (I just know French one ; but I guess that a third party payment plugin should handle it).
But it is not really the plugin which handle the feature, it's more the payment platform which propose options to set a "payment plan". So the best is to find a payment solution which propose that feature and then, see if there is a payment plugin for it or if it will be complicated to implement it.
