Shuup VS Spree Commerce

I once spoke to these guys and they're probably able to provide you with what you need. But if the 1k vendors aren't wishful thinking but existing leads with actual potential, you should be able to gave a custom solution funded.

I am wondering if a company could be operate based on the software that is open source. For example, shuup.com. This business looks like they have provided code on Github(https://github.com/shuup/shuup). Is it a safe thing to do so? Wouldn't hackers abuse by knowing how the system works? If this is a normal thing to do, what are the ups and downs?

A good system to study is Spree https://github.com/spree/spree. It has an inventory and billing system and supports different adjustments and sale configurations. If you don't want to use it wholesale it's a solid Rails application that does most of what you want so you can use it as solid inspiration.

Spree Commerce: https://spreecommerce.org/

Maybe Spree?

I'd say Solidus and Spree are you best options rather than trying to roll out you own ecommerce solution.

When I was working on that company, that mobile ordering app, Counterless, I looked a lot at codebases like Spree, the Spree Commerce codebase. And that's how I learned a lot about how do you model an order with line items and things like that? I saw some amazing things that helped me develop an understanding and save a ton of time by looking at oh, they have a state machine. What are the ways that an order transitions through all these different states as it gets processed and charged? And how do you track all of those things?
