About the build
In Sylhet, "ecommerce website development" usually means a pretty homepage and a checkout nobody finished
Here is what most people miss about ecommerce website development in Sylhet until launch week. The homepage is the easy 20%. Anyone with a theme and a weekend can make a clothing store look finished. Add a nice banner, a product grid and a cart icon in the corner, and it looks done.
The hard 80% is the development underneath. What happens when two people buy the last saree at the same time? How does a bKash payment match up with an order? What courier charge shows for a buyer in Beanibazar versus one in Dhaka? Is your stock count real, or just a number someone typed in once? That hidden 80% is the real job, and it is what gets skipped.
Ecommerce development in Sylhet has a common failure pattern. A shop in Bandar Bazar or Zindabazar pays 18,000 BDT to a part-timer. It gets a Facebook-shop-grade site with the developer's own bKash number hard-coded in. There is no stock logic. COD just emails an order, with no courier handoff. It looks live.
Then Eid traffic hits. The store oversells items it does not have. Customers who paid by bKash can't be matched to orders. The owner spends the whole sale season apologising on WhatsApp instead of shipping. The site was never developed. It was decorated.
I work as one senior developer, and I build the whole thing myself. The person who quotes you the price writes the checkout code. I set up payment matching and courier zones. I test it all on a real mid-range Android before you ever see "live." About five years of building WooCommerce stores has taught me where they really leak. Almost none of it is on the homepage.
Sylhet's seller mix is unique too. There are clothing and three-piece sellers and tea and agro exporters. There are dry-fish and handicraft brands shipping to relatives abroad, and electronics resellers. Each needs different stock and shipping logic, not the same template.
If your budget is honestly below 50,000 BDT, I will tell you to keep selling on Facebook with bKash a while longer and save. That is sequencing, not failure. I would rather say it than ship you something thin. When you are ready, the 50,000, 90,000 and 1,50,000 BDT tiers let you start lean. You grow into a fully custom build, from 3,00,000 BDT, only when your order volume justifies the engineering.
