If you don’t want to go down the shopify path and keep your shopping cart on your hosting server with your current website there are several options, all which I have done for our clients.
if you have wordpress then add a shopping plugin eg woocommerce
add a complete shopping cart cms and link between sites with a shop button on the menu
