The sale of goods 'online' is defined in The Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013 (CCR 2013) as a distance sale. As such, businesses operating in this sector need to ensure that their terms and conditions include specific content. From a practical perspective, the terms must include the business's contact details, details of how payments are made and the method for returning goods.

The terms should also outline the customers ability to return the goods and / or cancel the contract between the parties. Where the customer is consumer, the customer is entitled to cancel the contract within 14 of them receiving the goods (albeit subject to some restrictions).

A cookie is a small text file that a website or app sends to a user's device. These text files collect information about user actions on a specific website site. This information can subsequently be used to tailor the users experience on the website or display advertisement relevant to the user. A cookie policy seeks to outline the rationale for the owners of the website collating such data and inform the user of the website how this data will be used.

While often a standalone document, cookie policies are often integrated into Privacy Policies. A privacy policy is one of the most important documents on any website. It details the company's views and procedures on the information collected from its customers / visitors to the website. A privacy policy will outline what information is being collected, how it is being collected, information regarding how it is being stored and also how a customer / visitor can contact the firm. Importantly, the policy will also outline the customer's / visitor's rights with regard to requesting the company deletes any information held.

Code written in relation to a specific software project can be protected by copyright law. However, copyright law generally covers the artistic elements of a software program rather than the functional elements.

Businesses should ensure that when engage with a developer any intellectual property rights are correctly assigned. While material subject to copyright is normally retained by an employer, when engaging with a third-party it is imperative that the beneficiary of the work ensures that they retain full intellectual property rights (under English law the author of the code would normally retain the copyright of software).

The business will also need to verify that the party purporting to assign the rights to it is the actual owner, and that any contract between the parties contains a comprehensive IPR warranty and indemnity from the developer.

A business developing a website will want to make sure that it does what its are supposed to do. In this context, it is advisable to include an acceptance tests into the contract between the parties.

Such a test will provide various safeguards, including allowing for minor discrepancies or the ability for the developer to rectify its work if it does not pass the tests first time around without being deemed in breach of contract.

A developer may also insist on "deemed acceptance" provisions within the acceptance test clause. Such will outline how if the customer does not respond within a certain amount of time after the developer has made delivery, the website is deemed accepted and the final payment becomes due.
