How long before a dropshipping store makes money?
Most never do. Of those that do, the honest range is three to nine months to a first profitable month, and profitable months are not the same as a profitable year.
What decides it
The variable is not the product, it is how quickly you stop paying to learn. Stores that reach profit did so by killing tests fast and concentrating spend on the two or three lines that repeated.
The part that gets skipped
Dropshipping’s hard part was never finding a product — it is that you do not control delivery, and delivery is what a customer remembers.
The margin is thin by design, so the whole model depends on cheap traffic. When advertising gets more expensive, dropshipping stops working before anything else does.
A dropshipper who survives past the first year almost always stops dropshipping — they start holding stock for their best sellers, because that is where the margin is.
Where an app fits
An app is worth building once people buy from you a second time. Most dropshipping stores never reach that point, which is why the honest answer here is usually ‘not yet’.
