Really cool infographic. You’ve got just about everything covered. I actually sell a product just using paypal since I thought it might be the easiest for me to set up and it is what I am most familiar with. I guess really lots of ecommerce solutions even integrate with paypal however I do not run the sales of my products as a store just individual sales pages for a pay per product approach.
Imagine an ecommerce platform that allows customer service reps to have a single view of a customer across all channels, a centralized order and inventory management system that can efficiently fulfill orders from all your sales channels, including brick and mortar stores, or utilize a customer's order history data to provide personalized and relevant offers. The possibilities brought to light with the advent of a complete ecommerce platform for business optimization and improved efficiencies as well as deepened customer engagement and satisfaction are limited only by one's creativity.

Soundstripe is a third party licenser on behalf of our artists. Our artists are within their rights to use a Content ID system to monetize videos that use their content in an attempt to limit piracy. The Good News - this doesn’t apply to you! The Bad News - these companies use automated systems to identify the songs, and the system typically doesn’t know the difference between piracy and properly licensed music. Thankfully, disputing the claim is a simple fix! Here is a link that will walk you through disputing the claim with YouTube: https://support.google.com/youtube/answer/2797454?hl=en. When you get to the box that asks you to explain your claim, simply write, "Licensed through Soundstripe." That should take care of it, but if you continue to have issues, please reach out and we will work with you to ensure it's resolved in a timely manner.
Having an online storefront is one of the most straightforward ways to conduct ecommerce. The merchant creates a website and uses it to sell products and services using shopping carts and ecommerce solutions. The “right” solution will depend on the merchant and their products. Below is a list of some of the top ecommerce platforms. Check them out and see which one is right for you.
All you have to do is click on the gateway you want to add, and you’ll be sent to its official extension page. There you can choose which type of license you want to use and download the files you’ll need to set it up. Keep in mind that not all WooCommerce extensions are free, so you’ll want to focus only on the payment gateways you think your customer base will actually use.
The only downside in all this is that you somehow need to get your hands on a WordPress site in the first place. And okay, I know this is not particularly a problem for you maybe, but we have to remember that WordPress can be quite confusing to a beginner, and the need to first set up a WordPress site and only then a WooCommerce store is far from intuitive.
You can also get a range of child themes for Storefront in case you want to customize the look of your store further. Most of the child themes are available at $39 a piece (occasionally, though, there are themes with price tags as high as $119). If you're a developer with ecommerce clients, they have a package for $399 where you get all of the themes in the library.
OpenCart. OpenCart could be a great choice for small businesses without tech savvy employees. OpenCart is very simple to install and start using. It runs very quickly using simple code. OpenCart allows you to set advanced user privileges and separate access for users and groups. A simple code also has drawbacks; often for sale extensions and themes may not be up-to-date with security standards.

CUSTOMER SERVICE – Additionally, with a commercial solution you benefit from the support structure. Open source solutions such as WordPress are often community driven and you are therefore dependent on that community to provide support. While that can also work very well – if you are in desperate need of help at 3 am on a Sunday, it’s nice to have a guarantee it will be there.
