SHEIN FBS vs Self-Fulfillment Calculator
FBS (Fulfillment by SHEIN) costs more per unit but can lift conversion; self-fulfillment is cheaper but you carry freight, labor and SLA penalties. This calculator shows which keeps more profit, and the conversion lift FBS needs to win.
What is SHEIN Fulfillment (FBS) vs self-fulfillment?
SHEIN Fulfillment (FBS) is SHEIN's warehouse service — you send stock to a SHEIN warehouse and SHEIN picks, packs and ships for a per-unit handling fee plus storage. Self-fulfillment means you ship from your own warehouse and must hit SHEIN's 72-hour ship / 7-day delivery SLA, with late orders costing about $1 each and severe violations (false shipment, wrong item) penalized far more. This calculator compares the monthly net profit of both models and finds the conversion lift FBS needs to win.

FBS vs self-fulfillment on SHEIN
SHEIN lets you choose: send stock to SHEIN warehouses (FBS) or fulfill from your own warehouse / 3PL. The trade-off is cost per unit versus conversion and operational burden.
What FBS covers
Fulfillment by SHEIN stores, picks, packs and ships your products. You pay per-unit handling plus storage (free for the first 30 days, then per-unit/day), and return handling per order. In exchange you get faster delivery that reportedly converts ~22% better.
What self-fulfillment costs
You keep your own stock and ship it yourself. You carry freight, labor and packaging, and you must hit the 72-hour ship / 7-day delivery SLA — late orders cost about $1 each and hurt account health, while severe violations (false shipment, wrong item) carry much higher penalties. The calculator lets you budget penalties as a monthly line.
The honest decision rule
Run the break-even conversion lift. If your category genuinely lifts ~20% with FBS, it usually covers the fee; if you are a low-ASP or high-return SKU, self-fulfillment keeps more profit.
