Why are sales down after switching to a new platform?

Hi, I moved my site from a Zencart platform to Shopify on the advice of an expert. Since then sales have been 90% down. I think I really need more of a superhero than an expert, can anyone offer some highly recommended shopify experts that can offer some insights please?

@gointuk Sorry to hear that you’re facing difficulties with your Shopify store’s performance after migrating from Zencart. I can suggest some suggestions , can you please share store URL so will do basic audits for this.
