I run a small home fragrance business and my current website was built by a friend. It looks okay but the checkout page fails often and customers message me saying they cannot complete payment. I lost nearly 5000 dirhams in sales last month alone. Now I am searching for a skilled ecommerce web development company Dubai but I want to be careful this time. What technical questions should I ask to separate real experts from beginners? Should I ask to see their error logs or how they handle security updates? How do I know if they provide ongoing support after the site goes live without charging me for every small fix?
