For building ecommerce store in webflow I think these two Popular integration tools best for building ecommerce store using webflow
1) shopyflow
this tool allows you to connect Webflow's frontend and CMS with Shopify's backend. It only requires a Webflow CMS plan (not the e-commerce plan) and provides templates for product pages and store pages.
2) Smootify
Is a cheaper alternative to Shopyflow, though some users report it's not as easy to implement
The main advantage of using Shopify as a backend is that it provides more advanced features that Webflow's native e-commerce lacks just like
Multi-currency support
Custom discount systems
Advanced inventory management
Better payment processing
