Why the same store gets a 25,000 quote and a 90,000 quote
Picture one boutique selling three-piece sets. Two developers quote it. One says 25,000 taka, the other says 90,000, and from the outside the stores they describe sound the same: nice product pages, a cart, bKash, cash on delivery. The difference is everything you cannot see in a screenshot. In the cheap build, bKash is your personal number printed on the checkout page, so a customer pays, screenshots the transaction, messages you on WhatsApp, and you spend the evening matching payments to orders by hand.
There is no stock count, so during an Eid push you sell the same item to four people and disappoint three. Orders land in a shared inbox with no status, so by 9pm you have lost track of what shipped. The 25,000 taka was real, but it bought a brochure with a buy button, and the lost sales and refund arguments cost you the difference back inside a month.
The 90,000 build is the one where the checkout confirms the order, the stock drops on its own, the dashboard shows you what to pack, and the COD order is ready to hand to Pathao. That is the online store development price gap in BD, in one sentence: you are paying for the parts that handle money and orders correctly, which is the only reason a store exists.
Here is how I keep that price honest instead of just defaulting to the bigger number. I scope you into the lowest tier that fits how you actually sell right now. A new shop launching with forty products, manual bKash and Nagad confirmation, and cash on delivery does not need a card gateway or a courier API on day one, so I leave them out and do not charge for them, and a store like that lands near the 50,000 BDT floor.
A store already doing real volume that needs automated payments, live stock, courier handoff and clean order handling is a heavier build, usually 90,000 to 1,50,000 BDT, and I will tell you so plainly with the reason attached. A ground-up custom platform with unusual logic is where the 3,00,000 BDT range begins. You see the line items, every time: catalogue, checkout, dashboard, courier, trust layer.
Hosting and domain are a small yearly cost paid straight to the provider in your own name, never marked up through me, and your product photos and descriptions are yours to supply. The figure we shake on is the figure you pay at launch, and you can always point at a line and tell me to cut it to hit your budget.
