I had the same question and apparently some solutions exist. I would suggest you to first look for a financial advisor in order to also know what is exactly wrong on your website. I found a great one on https://yourmoneygeek.com/find-the-best-financial-advisor/ advice and suggestions. The guy was able to sit me down and explain me my budget mistakes. We also discussed how to implement a chat support on the site as customer satisfaction is key to any business. I have seen some great reviews on trustpilot and social media thanks to that.
An email address and phone number are enough for a small store to support your customers. But as your business grows, you’ll have to develop a support strategy that suits your customers according to your capabilities and budget. Properly organized customer support can be a very powerful weapon. It will “win over” those customers who were hesitant to choose you or not, help retain those who have already chosen you, and trigger what is known as “word of mouth.” But I needed a push for my business to start, and I got it by putting my online store on the Rakuten platform. It was a hard decision, but rakuten reviews convinced me to choose them. A huge plus is that customers like getting cash back on their purchases. It was after that that I started getting tremendous support from clients.
