I am out of my league here due to my limited technical knowledge compared to most people on stackshare. I am learning so I will contribute my thoughts in return plus stackshare asks me to add something that I have learned. I owned a good sized Internet candy distributor five years ago and about 8 years ago moved from Bigcommerce because they raised their price from $80.00 to something like $750 with only 2 months advanced notice to pay or leave. The price is fair but I should have been given maybe 6 months notice. I spent a month analyzing and testing other ecommerce solutions then another month finding a developer to help me move.

First, only choose a platform that's complicated like Magento if you can afford a developer to fix bugs and update security. I experienced some horrible developers but in the end found a great honest small shop to help me. Secondly, don't install a new version (in my case Magento 2.0) and stick with the time tester older version (Magento 1.X) until most big bugs are fixed. I know this information is old but not the lesson I learned which is timeless. My guess is Magento still needs to be updated constantly so stick with something like Shopify until your company grows larger.

The interoperability and reliability of Shopify is simply unmatched on the market. Having been a web developer for a few years, I cannot imagine going with any other solutions because of the level of development that would need to go into each and every tweak requested by stakeholders.

Shopify makes it easy to use apps off the shelf to test an idea, after which you can replace it with a custom solution or build on top of it.

Using their robust API, array of webhooks, Shopify Flow and Shopify Scripts, with a little know-how anything you want to do is just a few clicks or lines of code away from reality. The community is also pretty robust, so if you ever need help, you're not alone.

Full disclosure: I've been invested since 2015, but it's because they really are the best on the market.

We were about to migrate our older PHP 7.0 + Symfony 2.8 + Sylius 0.17 based E-commerce site to a more recent PHP stack. We were leaning towards Laravel as that has become our primary Framework in the recent years.

We chose Vanilo because it is so modular that it let us do the migration step by step and we could add the components we needed on the run. In total it took us 9 months to migrate everything from the old PHP 7.0 Symfony codebase to PHP 7.4/Laravel/Vanilo. We could also copy the old Admin theme to Vanilo thus the Admin users don't see any difference.
