Apple has the B2B App Store which allows a developer to "distribute tailored solutions directly to business customers". With this the app does not have to be visible to the general public.
Does Google Play have a similar setup that allows me to do the same thing? The Managed Google Play documentation has details for distribution (consumer end), but nothing detailing whether the publisher can restrict the app to particular business customers (as Windows Business Store and iOS B2B Store).
You can do this by using Google play private Chanel I am also doing the same thing for one of my customer below is link:
