The platform has an clear interface for both the merchant and the customer. It is clear where all the functions and data are on the site. Big Cartel also makes it easy to manage the products on your site and keep inventory. Merchants can also use Stripe or PayPal for the checkout.
The platform does not allow for extended customization, which is limiting especially if you would like to integrate your webstore into an existing website.
Also, if many customers have placed orders on your webstore, it can be difficult to keep track of them on the page with the orders. The orders are in a long list sorted from latest to earliest. In order to see specifics of each order, you have to click into the name of the customer. While you can search for orders by name, order number, or email, there is no function to sort the list or see orders by certain dates.
I needed an eCommerce platform to sell merchandise and only had a handful of products. I wanted an relatively inexpensive, but easy to use interface that allowed for some customization and inventory management. BigCartel had the amount of customization that I needed and had a great inventory management system. Its free tier also has many great features.
