A good checkout page can be an important factor contributing to the success of online businesses. There are some ways to perfect the checkout page and one of those is to add more custom fields in this page. Hence, in this article, we will learn why adding those fields to the checkout page is so essential for your site as well as the way to add them successfully for your site.

What is the checkout fields?

Checkout fields are fields which are displayed on the checkout page. Shoppers have to fill those required fields in order to finish the checkout process. Some examples of checkout fields are Name, email address, payment methods, etc.

Why do stores need to add custom fields?

In Default, in addition to some checkout fields as mentioned above, there are only a few fields which are delivery address or shipping methods. However, in business reality, store owners need to collect more custom information which is more specific and personalized. From the collected information, stores will find a way to serve their clients best.

For instance, when store owners would like to know about another address that customers can receive the items, they only need to add the attribute: “What another address will you receive this item. Then, stores can send the product to this address in case shoppers cannot receive at the provided shipping address.

In addition, stores can choose to add more fields to ask customers about their opinion of the store such as the product they buy from the store which they like the most.

Benefits of adding Custom Checkout Fields

Today, there is an increasing number of store owners who would like to find a tool allowing them to add more custom checkout fields. This trend can be well explained because having more additional fields is really beneficial for stores.

Benefits of adding Custom Checkout Fields

First, stores owners will have more information that they want about customers. If you want information about your clients to do a business strategy or to serve a specific target, adding custom fields in the checkout page is an easy way to collect that information.

Second, additional custom checkout fields will help you satisfy your clients. It is undeniable that when you know what your shoppers need in detail, you will have more chance to please them. For instance, you can send items to another address for customers when shoppers cannot receive at the provided address. It helps reduce wasting time dramatically. And when shoppers are satisfied with the store’s service, they will be more likely to make a purchase next time and become a loyal shopper.

Third, the image of the stores will be improved significantly. By adding more fields to the checkout page, store owners can have a deeper understanding of customers’ demand and have a solution to meet their expectation. As a result, store owners can perfect the image of stores.

Necessary fields to add to the checkout page

There are some fields that admins should add to the checkout page which are:
