Been playing with new GMB beta feature, Products (Beta) Looks to be replacement for Services menu located in Info tab. Set up collections with products in each collection. I am putting service items in as well. Any additional info here @mblumenthal ? pic.twitter.com/1UKyVXKfkb

As per the tweet of Schoell, with this feature businesses will ordinarily add services to their listing.
This feature will enable to show the name of the product, a 1,000 character description, the price, and a photo for each product.
If the business renders both products and services, there is no point to stop them from including a combination of both in GMB listing.
