The In-App Billing System (INABS) will allow you to integrate Google’s in-app billing service within Unity. It allows you to easily monetize your app by adding in-app purchases, get lists of available purchases and subscribe contents.
Included in the plugin is an demo scene which shows you the various functions available.
This plugin fully supports in-app billing version 3 and provides a number of simple delegate callbacks which you can hook up to your app (purchases, buyintent, isbillingsupported, consumePurchases, failed etc ...)

Note : this plugin doesn’t support in-app billing version 2.
