Risk definition:

The typical risks that an e-commerce organization will encounter are:

Online Security Breach:

One of the biggest problems that come with the online world is its security risks. There are many threats that are present in the digital universe. Hackers can breach the network and gain unprecedented access to sensitive information such as company data and customer’s credit card information. Our e-commerce website must be adequately protected.

Client Disputes:

Client disputes on-site can be a headache. One of the most common causes of client disputes is customer refunds. Customer refunds can happen when either the item was never delivered, the customer was dissatisfied with the product, if the product is damaged, or when the product delivered does not match the customer’s order.

Seller Disputes:

Just like a brick-and-mortar store, vendor disputes can be quite tricky. There are cases when sellers do not give the products on time or even not deliver at all. This issue can cause a considerable number of problems for our e-commerce website, especially when we are just starting.

Shipment Problems

E-commerce means hiring a courier service to deliver products from seller to the customer. The speed of delivery is one aspect that can boost customer retention and loyalty. Many problems can go wrong with a sketchy courier service:

• Huge shipping fees
• Packages not arriving on time
• Packages not even arriving
• Packages with damaged goods inside
• Packages going to the wrong address

Credit Card Scams

It is common for e-commerce websites to deal with stolen credit card information. Hackers, thieves, and frauds can easily use a credit card that is not theirs to complete a transaction.
