Shopify has categorized its experts according to their expertise. The major categories are designers, developers, marketers, app developers and photographers. Some would only cater to one specific category, while some Shopify Experts would undertake two or more of these tasks, say Shopify Store Design, Shopify Store Development, marketing and Shopify App Development. So, how to understand what your needs are? For that, it would be best if you write a specification of what you need for your products. This can help you in identifying your key audience, state your objectives, and workout your budget.
