What actually drives the price up or down in BD
A Dhaka agency might quote one client 70,000 BDT and another 2,80,000 BDT for what sounds like "the same website." The real difference is almost never the design. It is the scope hiding behind a vague brief. Page count moves the number: 5 pages versus 25. So does copywriting: do you provide it, or do I write it? Language matters too: English only, or Bangla and English.
Catalog size matters as well, like a 6-item service list versus a 200-item filterable directory. Then come integrations: you might need none, or you might need a bKash or Nagad payment gateway, SSLCommerz, courier APIs like Pathao or Steadfast, or a CRM hook. Each one adds real work, and real cost.
Some costs stay outside the build price on purpose. These are hosting, domain registration, premium plugin licenses, original photography, paid stock images and Google Workspace setup. Their costs are public and recurring. They belong on your books, not buried in mine.
A typical .com.bd domain costs about 800 BDT per year. Decent shared hosting for a business site costs 4,000 to 8,000 BDT per year. A one-time premium theme and plugin stack rarely goes over 8,000 BDT. I recommend specific providers, and you pay them directly, so there is no markup. That is how 50,000 BDT stays 50,000 BDT.
