Now that we've discussed the various Magento product types, let's go over the process of creating a new product in the Magento 2 backend. While there are some differences based on product type, the overall process and options are very similar.
After you go to Products | Catalog in the backend, you will see a list of the products in your catalog. In the upper right-hand corner is an orange button, titled Add Product. If you click on Add Product, you can create a simple, configurable, virtual, or downloadable product. For all types — including the bundled and grouped product types — you can also click the button menu (the down arrow on the right side of the button) and choose a specific product type.

The configurable, virtual, and downloadable product types can be created simply by changing settings within the simple product detail panel. For example, you can start with a simple product, add configurations, and the product type will automatically change to a configurable product type.
As we go through the product creation process, you'll learn that Magento has really upped their game in Magento 2, making it much easier for you to manage your products. For instance, you can start out adding all the various t-shirt styles you sell as simple products, and then go back and create the various size and color variants within those products. In Magento 1.x, you could not change the type of an existing product without first deleting the product, then re-adding it.
So, let's begin by building a simple product and then exploring how to create the other complex product types. For our example, we'll start with a red couch.
To begin, click on Add Product button on the Products | Catalog screen.
We're going to fill in the fields in the Product Details section as follows:
Save your product now before proceeding.
Next, we want to click the small down arrow to the right of Default at the top of the screen and type Furniture to select the Furniture Attribute Set we created earlier.

After the screen refreshes, you'll see an additional attribute group you created in the left sidebar, and any attributes you added to the attribute set will be available to you.

In the Furniture Specifications panel, we will enter the following values:
Under the Websites panel, we need to select Furniture Website so that the new product will appear in the stores within the furniture website.
We're going to leave all the other settings as they are for now and click on Save.
When we view the product on the website and click on the More Information tab, we can see the values of the attributes we have selected.

Let's say we have our couch available in three colors: red, blue, and green. How would we present all three choices as a single product yet allow the customer to select their desired color?
The simplest way would be to add colors as an option in our simple product. However, if we manage inventory separately for each color (let's say we have 100 red, 50 blue, and 30 green sofas in the warehouse), we have to, in essence, create three simple products and associate them to a single configurable product.
To do that, we have two options: auto-create the associated products from the configurable product or create the three individual simple products then associate them to a new, configurable product.
First, let's try method one using the couch simple product we just created:

First, you are allowed to choose whether to use the same images for all variants, or assign unique images to each. As with any of these choices, you can also opt to skip this for later.

Alternatively, within the Price box, you can assign the same or unique prices to all variations.

Finally, if you wish, you can assign inventory quantities for the associated products.

Having completed creating the configurable product, the product on the frontend now displays the color swatches for each variant (and removes the Color field from the More Information tab contents). As you click on each swatch, the main image will also change to reflect the image you uploaded for the particular variant.

In the backend, under Products | Catalog, you'll find four products now: the Configurable Product and the three new associated Simple Products.

Alternatively, if you already have the Simple Products added to your store, you can create the configurable product and add the associated products manually instead of creating them automatically, as we just did.
If you have a collection of related products, such as yoga straps (included in the Magento 2 Sample Data set), you can present them as a group. Customers can then select which individual items they want by entering a quantity for each associated product.
To create a grouped product, choose Grouped Product in the Add Product dropdown menu, as shown in the following screenshot:

At the bottom of the Product Details screen, under Grouped Products, you add products to the group and any default quantity you wish to set (customers can always override any default).

Grouped products are not really products at all but simply a virtual grouping of products you wish to present together.
Bundled products are similar to grouped products but with some differences. The biggest difference is that you are creating a bundle of products presented to the customer as one "set" or "bundle." Furthermore, you can configure the product so that the customer can select options of each product, if they wish.
Let's look at the Sprite Yoga Companion Kit product provided in the Magento 2 Sample Data. This is a bundle of yoga equipment that has been configured to include four required products: a Stasis Ball, a Foam Yoga Brick, a Yoga Strap, and a Foam Roller. Customers can select larger balls and longer straps. The price of the bundle is automatically calculated based on their selections.

When the customer clicks on Customize and Add to Cart, the choices available for the bundle are revealed.
First are the choices for the Stasis Ball:

As customers select alternative sizes, the total cost of the bundle will adjust accordingly.
Bundled products are created in two steps: creating the options for each bundle component, then attaching simple products to those options.
Let's build the Sprite Stasis Ball bundle option, as shown, in the Product Detail screen to illustrate this two-step process.

Once you have created your options and attached the associated products, you can save your product.
In today's digital world, many online retailers offer files that can be purchased and downloaded, such as books, music, and software. Creating a downloadable product is achieved by attaching the files to the product. Once purchased, the customer will receive a link they can click to download their purchase to their computer.
Note that many downloadable products cannot be redeemed on mobile devices. Music, for example, may not always be able to be downloaded and played on a mobile device by clicking the redemption link. Please experiment and test your offerings so you know how to communicate any restrictions to your customers.
A downloadable product is created by making two initial selections:
In the Downloadable Information panel, there are two sections: Links and Samples. The Links section allows you to attach files that will be provided to customers once they purchase your products. The Samples section will provide linked files for shoppers to download as examples of what they will get when they buy the product. You can also use this section to attach files to promote the product.
When creating a downloadable product, you have controls over how easily it is for the customer to share their download link and how many times they can download their purchase. While these are not foolproof, they can help restrict the distribution of your digital products.
A virtual product is just as it sounds: a product that doesn't actually exist, but can be purchased by the customer. Basically, a virtual product is one that has no weight and therefore cannot be shipped.
What kinds of product fall into this type? We've used the virtual product type for extended warranties, training courses, and hosting packages.
