Cost 1: building the store
What drives the price is the number of products and variants, how much of the design is made from scratch, and how many systems the store talks to. A Shopify store with a ready theme, twenty products and mobile pay is a small project. A store with a thousand items from a supplier file, separate prices for business customers and links to stock and accounting is a big one.
Ask for a quote that separates setup, design, product import and integrations. Then you see what you pay for, and what you can do yourself to lower the price, such as entering the products.
