If you have an e-commerce solution on your site which allows you to sell products online, the checkout page allows your customers to complete their order and move on to payment. This part of your e commerce system will collect all the necessary information from the user to move onto processing and payment including confirmation of the sale and product information, the user details and their billing details.

Be sure that you know what it is you require from the buyer in order for a successful order to occur and that this process is efficient and easy to follow. 

Remember also that contact details are key. Collecting your customers contact details such as email address, phone number and postal address will allow you to ensure that you can communicate with your customer easily as well as give you the opportunity to further promote your products to them through mail outs, email news letters and updates on promotions.
