How FBS works for a seller
FBS stands for fulfillment by seller. Your goods stay with you, whether in a warehouse, a shop or a back room. When an order appears in your seller account, you pick it, pack it, add any required labelling and hand it to the marketplace within the deadline, either at a drop-off point or to a courier. The platform then delivers it to the customer.
The catch is discipline. Shipping deadlines are strict, and a missed one usually hurts your seller rating or brings a penalty. Rules differ between platforms, so rely on the offer agreement and your own account, not on what another seller told you.
How FBO works: stock at the platform's warehouse
With FBO, fulfillment by operator, you deliver a batch to the marketplace warehouse in advance. The platform picks, packs, delivers and processes returns. You are not standing at a packing table every morning, and customers often receive orders faster because the goods are already nearby.
In exchange you pay for storage and logistics, follow inbound rules on packaging, labelling and booking a receiving slot, and tie up cash in stock sitting in someone else's warehouse. A slow-moving item keeps costing you storage fees every day it stays there.
FBO vs FBS in daily operations
It helps to compare the schemes by what actually changes in your working week rather than by definitions.
- Storage: with FBS you pay for your own space; with FBO you pay the platform for each day of storage.
- Speed: FBO is usually faster, and some platforms rank such items higher or mark them as fast delivery.
- Workload: FBS means daily picking and packing; FBO means planning shipments in batches.
- Control: under FBS the stock is in your hands; under FBO, receiving or storage errors go through platform support.
- Risk: FBS risks penalties for late shipping; FBO risks fees on goods that do not sell.
When FBS fits and when FBO fits
Picture a phone accessories shop in Tashkent. Cases and chargers sell daily, and the items are small and cheap. Sending them to the platform warehouse under FBO makes sense: fast delivery helps in a competitive category, and storage takes little space.
Now take a furniture workshop in Samarkand or a seller of large appliances. Bulky goods are expensive to store in someone else's warehouse, and some pieces are made to order. FBS suits this better, and for the heaviest items some sellers use DBS, delivering themselves. Not every platform offers every scheme, so confirm what is available before you plan.
FBS also makes sense if you sell the same goods through Instagram, Telegram or a physical shop. One stock is easier to run, but watch your counts so you do not sell the same unit twice.
A mixed model and how to run the numbers
Many sellers do not pick one scheme for good. Fast movers sit at the platform warehouse under FBO, while the rest of the range and new products go through FBS. A new item is tested in small volumes first and moved to the platform warehouse only once sales prove it.
To base the decision on facts, calculate each product separately using the real tariffs shown in your account:
- storage and logistics costs under FBO;
- packaging, picker time and transport to the drop-off point under FBS;
- the difference in sales caused by delivery speed;
- the cost of returns and where returned goods end up;
- cash frozen in stock at the platform warehouse.
Common seller mistakes
The choice is part of your marketing strategy, not just logistics: it affects margin, how much you can spend on ads and how deep a discount can go. These are the errors that most often break the math.
- Sending the whole range to the platform warehouse and paying to store slow items.
- Choosing FBS without people or time for daily picking, then collecting penalties.
- Ignoring packaging and labelling requirements for inbound shipments.
- Copying a competitor's scheme without your own calculation.
- Never revisiting the choice after sales grow or fall.
Where to start
You can change schemes later, so begin with the one that is simpler for your situation and review it against sales and cost data as you go.

FAQ
What is the main difference between FBO and FBS?
Under FBS the seller stores goods and packs each order. Under FBO the goods sit at the marketplace warehouse, and the platform picks, packs and delivers.
Which scheme is better for a new seller?
Many start with FBS because there is no storage fee and no need to ship a large batch. Once some products sell steadily, they can move to FBO. The final answer comes from your own calculation on the platform's tariffs.
Can I use FBO and FBS at the same time?
Yes. Many sellers keep fast movers under FBO and slow or new items under FBS. Check the platform's terms to see which schemes it supports.
What happens if I miss a shipping deadline under FBS?
Platforms usually lower the seller rating or apply penalties. The exact consequences are set out in the offer agreement and your seller account.
