What do you dislike about Shopify?
First and foremost, read the Terms and Conditions for this service before signing up! The Terms state that all intellectual property that you put on "your" website can be accessed and kept by Shopify and used or passed on to other companies however they choose, for all time. Your marketing materials; product, sales, and inventory data; and theoretically customer data are all irrevocably licensed to numerous unknowable third-parties for all time.
To add insult to injury, Small Business plans are restricted from accessing order and customer data that was entered on their site, by their customers, and is vital to many integrations and business operations. While this is ostensibly for "security" reasons, I fail to understand how it's a security risk to access your own business data. Of course, you can get around this by upgrading your plan to at least the $399 USD/month Advanced Plan and gain this access (because only small businesses are insecure apparently).
The "Basic" and "Shopify" plans further restrict you to using Shopify Payments, with no ability to utilize existing merchant accounts. Which, of course, would incentivize you to also use their POS platform (at which point your in-person customer and sales data is also permanently transferred to Shopify and inaccessible to you).
While you can utilize your own shipping services, these plans show Shopify Shipping rates to customers at checkout, which are marked up from standard, widely available commercial discounts.
For example, a USPS postage stamp, which costs $0.69 USD via numerous other providers, costs $1.40 to buy from Shopify. Of course, if you upgrade your account they will reduce their markup on shipping fees as a perk and to further deter you from using more convenient and flexible third-party services.
