I recently helped a friend plan an online shop for products that came in different sizes, colors, and bundles. We found that custom ecommerce web development could be useful because the usual store layouts did not support the way he wanted customers to browse and build their orders. We discussed features like flexible product options, saved carts, and clearer order summaries, while keeping the shopping process simple. It also made me realize that adding too many features at the start can create unnecessary work. If you were launching a store, what would you customize first?
