Once you finish setting up your online shop, you can share your shop link anywhere you need to. You can also ask existing customers who buy through WhatsApp to use your online shop instead of manually processing their order. This way, you can just concentrate on actually fulfilling the orders, instead of closing the sales.
Your online shop will also make it easy for your customer to browse, choose, and pay for the order. You will know exactly what they want to buy, there's no confusion and back and forth needed with customers.
