WooCommerce is WordPress with a shopping cart duct-taped to it. It's "free" and runs about 20% of online stores - second biggest after Shopify, which should tell you something about how desperate people are to avoid Shopify's fees.
Here's the thing - WooCommerce is just a WordPress plugin. WordPress runs 43% of the internet, so slapping eCommerce on top should work great, right? Yeah, about that...
The Good: You Own Everything
Unlike Shopify where you're renting space, with WooCommerce you own the whole damn thing. Your data, your customer list, your product catalog - it's all yours. No platform can hold your business hostage or jack up prices whenever they feel like it.
This matters more than you think. I've seen businesses lose years of SEO rankings because they had to migrate off a hosted platform. With WooCommerce, you control your URLs, your content, and your destiny.
The Bad: WordPress Will Make You Want to Quit
Here's what they don't tell you: WooCommerce inherits every fucking WordPress problem. Plugin conflicts that make no sense, security holes you didn't know existed, performance that tanks for no reason - you get the whole shitshow. Debugging a WooCommerce store at 3am when orders aren't processing? I wanted to throw my laptop out the window. Spent 6 hours troubleshooting payment failures once, only to discover a security plugin was silently blocking PayPal's IPN callbacks. Six. Hours.
The learning curve? Brutal. If you've never touched WordPress, you're in for a world of pain. Themes, plugins, MySQL databases, PHP - you'll need all of it the moment you want something that doesn't suck.
Market Reality Check
WooCommerce runs somewhere between 13% and 39% of online stores depending on who's counting. The numbers are all over the place, but it's definitely huge - over 4.6 million live stores worldwide.
Reality check: most WooCommerce stores are small businesses who picked it because "free." The real costs hit you like a freight train later - hosting that doesn't suck, security that actually works, development to fix what breaks, extensions for basic functionality. Budget $2,000-5,000/year minimum if you want a store that won't embarrass you.
They push updates regularly (currently on 10.x), but every update is Russian roulette with your store. WooCommerce 8.5 broke thousands of stores overnight by changing how product variations worked - no warning, just broken checkouts on Monday morning. Test updates on staging first, or learn this lesson at 3am when your phone won't stop buzzing with "I can't checkout" support tickets.
