Different digital businesses have different needs and if you are going to have a multi-product website, you may need a shopping cart.
Today, shopping carts have become very good and easy to use, with great features and functionality. The shopping carts that I recommend here are intuitive, so you do not need to worry too much about the user experience.
And as your business and customer volume grows, you'll need a robust CRM system to manage the marketing campaigns of your multiple products.
An awesome and robust CRM system
ZenDesk is a CRM that is awesome. I use it to run my entire Entrepreneur Lab Support Center and I could not be happier with it. If you are just getting started, simple email support is free and easy but once you start supporting multiple products and a higher volume of customers email is not reliable enough and that is when you should consider a system like ZenDesk.
The Porsche of ecommerce systems
Think of ONTRAPORT as the Porsche of ecommerce systems. This is the system I personally use for my main businesses. It is a truly a marketer’s dream system with the ability to create complex marketing campaigns with advanced logic using a relatively simple interface. There is definitely a learning curve but once you have it figured out the power of ONTRAPORT is phenomenal.
The downside? The price. It is out of reach for most people getting started online with a heavy startup cost (you'll need help to truly maximize this software) and high monthly fee. For a more established business generating any revenue ONTRAPORT is definitely a worthwhile investment and will pay for itself over and over.
Online shopping cart for your products
If you sell anything online, you're going to need a way to do that - Shopify is one of the tools you can use and it provides an online shopping cart for your products.
Turns your site into a robust ecommerce site
If you want to turn your WordPress website into an ecommerce site with multiple products in different categories with a robust shopping cart then you can’t beat the free WooCommerce plugin from WooThemes.
It is compatible with most themes but I always recommend using it with one of WooThemes’ “eCommerce Themes” to take advantage of all of the functionality.
