Why should I move from my current ecommerce site using Paypal Shopping Cart to Shopify?

Don't move it, just integrate PayPal Pro. Why are you thinking about moving?

I'm software developer and I really don’t know why. It's very controversial platform and now I tell you the reasons. While some e-commerce experts consider Shopify like the most featured ready-to-use e-commerce platform, others don’t. It really has all the basic features which any small business may need: product cards, order CRM, built-in analytics, payment gateway integrated, fraud analysis, blog, social network's integration, etc., But I'm not sure what support is available for exporting data when the time comes to migrate to a different system. It has no one-page checkout - can hurt conversion rates, limited payment gateways for the non-major markets (USA, Canada, UK). Are you sure you want to migrate to its platform? Besides, you will have to pay over $280 monthly (plus transactional fees) to get all Shopify features. I can’t say I'm happy that cost can rise dramatically once you add some 'apps' which really should be baked into the core platform (e.g., reviews, social login).I suggest you to have to look at ShoppingCart.Elite. They offer an all-in-one solution so you won’t need to rely on dozens of different apps, plugins, extensions, and/or integrations to run your business. They have some of the best features you’ll find in terms of marketing, marketplace management, ERP and analytics and I find them to be affordable. Their only downside I think is that they don’t offer a cheap starter plan, but if you’re really serious about e-commerce you’re not going to get much with cheap solutions any ways. Mostly, I like the built-in tool - Threat and Engagement Analytics Software(TEA). TEA offers you a lot of great opportunities to promote your website and boost sales. They have a free demo trial which is definitely helpful. So in terms of price, quality, I think it’s worth it.Disclosure: I am a software developer and used this platform.
