Dropshipping is an online retail model in which you sell a product you don't keep in stock: when someone buys it, you pass the order to your supplier, who ships it directly to your customer. Your store sells and collects payment; the supplier stores, packs and ships.
It's a perfectly legitimate way to start selling, and at certain stages it's the best one. But it comes with a cost you don't notice at first: you hand over control of everything that happens after the customer clicks "buy."
How a dropshipping order flows
- The customer buys from your store and pays your retail price.
- You buy that same product from your supplier at their price and send them the customer's shipping details.
- The supplier packs and ships it to the buyer, using their carrier and on their schedule.
- Your profit is the difference between what you charged and what you paid the supplier, minus fees and advertising.
The upside is real: the customer's money comes in before you buy anything. There's no inventory paid for up front and no warehouse to rent.
What the flow doesn't show is the thing you never see: the product itself. You don't check its quality, you don't choose the box and you don't decide when it ships.
What dropshipping is good for
- Testing products. You can try ten products without buying hundreds of units of each, and keep the ones that actually sell.
- Long-tail catalogs. Items that sell a few times a month don't justify taking up warehouse space.
- Starting on a small budget. You pay for the goods once they're already sold.
The model isn't the problem. Staying in it after the business needs something else is.
Dropshipping vs fulfillment from your own inventory
The alternative is to buy inventory and have someone store it and ship each order: either you, or a 3PL (a third-party logistics provider that stores and ships for you). That process is called fulfillment, and we cover it in depth in what fulfillment companies are. Here's how the two models compare:
| Dropshipping | Fulfillment from your own inventory | |
|---|---|---|
| Who holds the stock | The supplier | You, in your own warehouse or a 3PL's |
| Control over delivery time | Depends on when and where the supplier ships from | You choose the ship-from city and when orders reach the carrier |
| Packaging and branding | Whatever the supplier uses | Yours: box, fill, insert, label |
| Unit margin | You pay a single-unit price | You buy in volume, but pay before you sell |
| Overselling risk | High: the supplier can run out without telling you in time | Low if your inventory syncs with your sales channels |
| Returns | Have to be coordinated with the supplier | Come back to your warehouse, and you decide what goes back on sale |
| Upfront investment | Close to zero | Inventory plus the cost of storing and shipping it |
Overselling (selling a unit that no longer exists) deserves a closer look. In dropshipping, your "available" stock is whatever the supplier reports, and that same stock may be listed by other stores too. You find out it was gone after the order has already been paid.
Signs the model no longer fits
1. Your delivery times are long and you can't promise them. If the supplier ships from far away or takes days to dispatch, your store absorbs the wait. And you can't fix it, because the product isn't where you decide it should be.
2. Complaints land on you, not the supplier. Customers don't know who sent the package. If it arrives damaged, incomplete or late, the review is about your brand, and you don't have the product on hand to fix things quickly.
3. You don't control the packaging. You can't add your own box, a thank-you card or packaging that protects the product better. On some channels it's also a requirement. On its US selling partner blog (August 2025), Amazon explains that its policy only allows dropshipping if you have an agreement with your supplier identifying you as the seller of record, if the packaging, packing slips and invoices make no reference to a third party, and if you accept and process returns yourself.
4. You want to sell on marketplaces that track your shipping times. On Mercado Libre, your seller reputation is built on on-time shipping, as we explain in Mercado Libre fulfillment in Mexico. With a supplier who dispatches on their own timeline, every delay counts against you.
5. You already know what sells. If a product moves steadily week after week, it's been validated. Paying for it one unit at a time means paying for uncertainty you no longer have.
How to switch without betting everything
It doesn't have to be all or nothing. A sensible path:
- Move your best sellers first into your own inventory, and keep the rest of the catalog on dropshipping while you keep testing it.
- Run the full numbers before buying in volume: storage, order preparation and shipping. How much a 3PL costs in Mexico breaks this down.
- Decide on your packaging. With your own stock, you get to choose how every order looks and how well it's protected. Here's how orders get prepared in a warehouse: what pick and pack is.
- Sync your inventory across every channel so the switch doesn't bring back the same overselling you were trying to escape.
Frequently asked questions
What is dropshipping in simple terms?
It's selling products you don't hold in stock. You make the sale and your supplier ships the product straight to the customer.
What's the difference between dropshipping and fulfillment?
With dropshipping, the inventory belongs to the supplier and they ship it. With fulfillment, the inventory is yours and it's shipped by you or a 3PL, so you control timing, packaging and returns.
Can you dropship on Amazon?
Yes, with conditions. According to Amazon, you must be the seller of record, the package can't reference the supplier, and you're responsible for returns.
Can I combine dropshipping with my own inventory?
Yes, and it's usually the healthiest transition: your own stock for what sells consistently, dropshipping for what you're still testing.
