Hello, when you receive emails from customers with questions or the request to return an order etc, do you answer everything by yourself or did you start using an external customer service provider? If yes, can you recommend one? Thank you so much for sharing your experience !
I recommend handling it yourself for the first couple months, and documenting common procedures in a SOP (Standard Operating Procedure).
Then hire a customer service person, and give them the SOP so they know how to manage your customer support as you would.
To find someone to her you can ask around within your community for recommendations, do a Google search, check the Shopify Experts portal, etc.
I recommend hiring someone for 1 month to see if they're a good fit for your business, if yes then continue, if not then hire again. A good customer support person is essential to managing that part of your business with good energy, so you can focus on growing the business.
