SFP vs FBA: Which is Better for Your Amazon Business in 2026?
If you sell on Amazon and you've been researching your fulfilment options, you've probably come across two programmes that dominate the conversation: FBA (Fulfillment by Amazon) and SFP (Seller Fulfilled Prime). Both give you access to Amazon's vast Prime customer base. Both can display the coveted Prime badge on your listings. But they work very differently — and choosing the wrong one can cost you thousands of pounds in unnecessary fees, lost inventory control, or account health risks.
In this guide, we'll compare SFP and FBA head to head across every dimension that matters: costs, control, compliance, performance, and scalability. By the end, you'll know exactly which is right for your business — and how to make the switch if you're currently on the wrong option.
The short answer: FBA is easier. SFP is often cheaper. The right choice depends on your product type, margins, and operational setup.

What is FBA?
Fulfillment by Amazon (FBA) is Amazon's own fulfilment service. You send your inventory to Amazon's warehouses (fulfilment centres), and Amazon handles everything from there: picking, packing, shipping, customer service, and returns. Your listings automatically get the Prime badge.
FBA is the default choice for many new sellers because it removes almost all operational burden. You focus on sourcing and selling; Amazon handles the logistics. However, this convenience comes at a cost — quite literally.

What is Seller Fulfilled Prime (SFP)?
Seller Fulfilled Prime lets you display the Prime badge while fulfilling orders yourself — either from your own warehouse or through a 3PL like Pick Pack Pro. Customers see the same Prime promise. The difference is your stock never goes near an Amazon fulfilment centre.
To qualify, you must pass an Amazon trial where you meet strict delivery standards: same-day dispatch, next-day delivery, a 99%+ on-time rate, 98%+ Buy Shipping compliance, and a cancellation rate under 0.5%.

|---|---|---|
| Pick & pack / fulfilment fee | £3.10–£3.60 (Amazon fee) | £1.20–£2.00 (3PL fee) |
| Storage (monthly, per unit) | £0.75–£3.00 (size & season) | £0.20–£0.60 (3PL storage) |
| Inbound shipping (per unit) | £0.40–£0.80 (to Amazon FC) | £0.15–£0.30 (to 3PL, one site) |

| Q4 storage surcharge | Yes — can add £1.50+/unit | None |
| Long‑term storage risk | Yes (after 365 days) | None — your stock, your rules |
| TOTAL estimated per order | £4.25–£8.40 | £2.05–£4.40 |
At 500 orders/month, SFP via a quality 3PL could save £1,100–£2,000 monthly vs FBA — that's £13,000–£24,000 per year.

Which is Better? The Decision Framework
| Choose FBA if… | Choose SFP if… |
|---|---|
| • You're a new seller without warehouse infrastructure • < 50 orders/day and want simplicity • Products are small, standard, and fast‑moving • You sell only on Amazon • You can absorb FBA's fee structure | • 50+ orders/day and fees hurt your margin • Oversized/hazmat/slow‑moving products • You want multi‑channel with one stock pool • Restock limits/Q4 fees/check‑in delays hurt • You need branded packaging and control |
Can You Use Both FBA and SFP at the Same Time?
Yes — and many sellers do exactly this. A hybrid approach lets you optimise for each product category. Fast‑moving, standard‑size products go through FBA; oversized, slow‑moving or multi‑channel products go through SFP. That balance maximises margin and control without sacrificing Prime.
