My current website is up and running, yet it stops short of letting visitors buy anything. The focus of this update is squarely on adding full-scale e-commerce functionality, with a smooth, reliable shopping-cart flow at its heart. Here is what I need done: • Integrate a shopping cart that keeps items persistent across sessions, works flawlessly on mobile and desktop, and updates totals in real time. • Re-work the existing page layouts just enough to showcase products attractively and guide users toward checkout without clutter or extra clicks. • Connect the cart to a secure payment solution (I’m open to your recommendation) and make sure order confirmation emails fire correctly. • Migrate or create any back-end settings required—tax, shipping, coupon logic—so I can manage them from an admin dashboard. The rest of the look and feel can stay recognizable; think of this as a functional expansion rather than a full visual overhaul. Clean code, clear documentation, and a staging link for review are essential for hand-off. Once everything tests out end-to-end, we can schedule the go-live.
