Why the dynamic-site price swings so hard
You are not paying for pages. You are paying for the engine behind them.
The hidden cost of a cheap dynamic website in Dhaka is not the quote — it is the per-edit tax that comes after. A trading house in Motijheel or a clothing brand off Dhanmondi 27 buys a 'dynamic' site for 40,000 BDT, then discovers the admin panel barely works: to change a price they message the developer, to post a notice they message the developer, to add a product they message the developer, and each time it is 1,500 or 2,000 taka and a two-day wait.
Eight months later they have paid the build price all over again in edit fees and still cannot touch their own site. That is a static site wearing a dynamic site's name tag, and the low quote was the bait.
A real dynamic website design in Dhaka is priced by what is actually built behind the screen, not by the page count you see on the front.
The honest drivers are these: how many content modules you need (products, services, projects, notices, blog, team, gallery), whether visitors need search and category filtering, whether forms must save submissions to a database and export to Excel, whether you need role-based admin access so staff see only their section, and which integrations sit on top — bKash, Nagad, SSLCommerz, or a courier API like Pathao or Steadfast. Each of those is real engineering time.
A five-page static brochure has none of it, which is exactly why it is cheaper and why quoting the two at the same number is dishonest in either direction.
I am RH Fardin. For about five years I have built dynamic websites for Dhaka businesses as a one-person studio — no agency, no juniors, no project manager turning your requirement into someone else's first draft. The person you message is the person who maps your admin around how you actually work, writes the code, wires the database, connects the contact and order forms, and pushes it live. That is the whole reason I can hold a 50,000 BDT floor on dynamic work in a city where a Banani firm has to quote far more just to cover a five-person payroll and the office rent.
So treat this page as the breakdown, not a brochure: what 50,000, 90,000, and 1,50,000 BDT buy in terms of modules and admin depth, where custom builds above 3,00,000 BDT begin, and how to read any Dhaka dynamic-site quote so you can tell a genuine database build from a static page with a fake login bolted on. One thing I will not do is win you on price by faking the dynamic part.
Below 50,000 BDT I cannot build an admin panel that fits your business, structure the database properly, test it on a budget Android on patchy 4G, and still stand behind it six months on. If your real budget is under 40,000 BDT, I will say so on the first call rather than hand you a thin site with my name on it.
