Ask HN: What is the best tech stack or platform for an ecommerce site?

What is the best stack for a medium to high volume ecommerce site?

  Our focus is fast and reliable performance, the ability to call our CRMs APIs, no transaction fees on the platform, and have the ability for a user to login to see past orders and other info from our CRM.  Our checkout process will need to be web forms that use a particular vendors API.  I'm not sure the best cart and storefront functionality.  Right now we use a shopify front end and pass products via UTM parameters to the checkout page.  We don't use Shopify as the transaction fees are pretty high when you take into account upsells, and the other plugins we'd need to operate.  We're thinking about migrating to wordpress and woocommerce, so we can integrate wordpress users to offer our customers the ability to login to the store, see their passed orders, and other information.

Is building this in woocommerce/wordpress viable? Or is creating a type of JAMstack site on the more custom side to go with our custom cart a better long term solution? Seems like headless CMS is all the rage these days.

We have about 10k visitators a day, 500 sales a day, with another 500 interacting with our site as adding to our email list. We expect to hit 20k+ visitors a day fairly quickly (within 6 months).

I have not, I'll look into this.

We'd be fine with migrating off of PHP.

I have a lot of experience with WP and WooCommerce so I may be biased but 500 sales a day with 10K visitors a day should be fairly achievable in WordPress/WooCommerce. It can be scaled even more if needed. If you want to worry about business and not tech, forget about shiny things like JAMStack, HeadLess CMS etc. Play with them for hobby on the side but for real business, go with something tested like WooCommerce if that is an option for you.

Shopify can work too if you want to give them more control. Cost wise, I wouldn't say WP/WooCommerce will be cheaper necessarily because you have to factor in costs of servers, maintenance and most important: technical resource/support as/when needed.

However, WP will give you the ability to customize as needed WooCommerce is very written with an excellent plugin system (some 3rd party plugins can be costly but totally worth it in my opinion). Most importantly, WP and WooCommerce is all yours and you are not vendor locked in as in with Shopify.

WooCommerce = More Power, flexibility but more responsibility.
