How to setup a Shopping Cart with Paypal

eCommerce solution shopping cart

A custom shopping cart for a website allows multiple products to be added. The customer can continue to shop and add items to the cart.

There are various techniques for this, some will store tempory information in the session and retrieve it upon checkout. Others will store information in cookies or actually in a temporary database table.

The problem with normal web pages (html) is that they are static with no infomation being retained between calls to the server. Hence any shopping cart has to be able to record this information based on your visit. Most of this happens without any noticable effect to the user of the shopping cart. This info is only useful to help understand why a shopping cart isn't as simple as you may expect.

Why use a paypal shopping cart?

  • Well recognised brand due to being part of ebay
  • No merchant account or gateway required
  • Secure with a console to retrieve funds
  • Inexpensive especially for low volume sales

Steps in Setting up your shopping cart

  • Get an account with Paypal (how to setup an Account with PayPal)
  • Ensure the account business name is what customers are expecting on their statements
  • Log in to your account and click on the Merchant tools menu item
  • Under the key features box choose PayPal shopping cart
  • Follow the steps in creating a shopping cart and paste them into your HTML code

International Currencies and Destinations


PayPal follow the country codes and names that are defined by ISO 3166-1 (International Standards Organisation).
When creating a cart you need to ensure that the correct info is passed into PayPal.
You can test this by creating a developer account and testing your shopping cart without any cost.

Custom Shipping


You can pass info to PayPal about shipping costs and handling costs. Hence you can create a custom shopping cart with specially calculated shipping costs. For example this product cannot be shipped to this state or this product to this state has a rate per kg or a tiered rate.

Summary

In summary you do the following when creating the cart :-

  • Add an add to cart button for each item you are selling
  • Specify the cost of the item including name and postage fees
  • Set the logo etc that appears when the customer moves to the PayPal secure site
  • Add some code to allow the cart to function between web pages
  • Add some code so that the customer can view the cart with all items in it


Virtually any shopping cart can be integrated into the PayPal system including custom made shopping carts by your designer. Info from PayPal on this is available at Adding PayPal Checkout to Your third-party Shopping Cart
You can either pass the aggregate amount to PayPal or pass the individual products which will be itemised on the PayPal site via the information about the items will be included in the buyers' and sellers' History logs and notifications.
This is important to ensure your customers do not dispute any transactions.

Custom shopping cart or DIY Shopping Cart (off the shelf)

You may not need a custom shopping cart - there are some excellent off the shelf shopping carts - many of which I have explored whilst conducting search engine optimisation for my clients. Generally they do require either you or your web developer to have a very thorough understanding of HTML and usually PHP and MySQL databases.

Some shopping carts need to be very complicated or else rendered useless quite easily. For example what if you want to vary sizes styles and prices of products without having to enter one product for every variation. This can easily equate to 1000's of entries.
Hence the cart may be cheap or even free but you have to manually enter so much info that it costs you or your staff a fortune.

A custom shopping cart allows for-:

  • Varying prices styles and sizes
  • Abilty to indicate out of stock items
  • Vary how payment is recieved (e.g. login or straight to payment)
  • Secure system more difficult for hackers to guess logins
  • Varying delivery calculations depending on location and product
  • Can build the design to best match how a shopper prefers to browse
  • Group products how it suits your shoppers
