I own a small organic spice shop and last year I paid a company 12,000 dirhams to build my online store. The site worked fine for two months then started showing wrong prices and double charging customers. I lost many regular buyers because they did not trust my website anymore. Now I am searching for a reliable ecommerce web development company Dubai but every firm looks good on paper. How do I check if they actually know how to build secure stores? Should I ask for a list of stores they built two years ago to see if those sites still work properly without issues?
