Explained: Your Route to Fulfillment Clarity, Prime Power, and European Growth
When it comes to selling on Amazon, logistics isn’t just something happening in the background — it’s the backbone of your customer experience and a major driver of your profitability. Whether you’re trying to hit that coveted Prime badge, reduce delivery times, or expand across borders, how you fulfill orders shapes your success more than almost anything else.
Amazon offers three primary fulfillment options: Fulfilled by Amazon (FBA), Fulfilled by Merchant (FBM), and Seller Fulfilled Prime (SFP). Each comes with its own rules, costs, advantages, and headaches. And if you’re selling into the European Union or beyond, you’ll also need to get your head around programs like Pan-European FBA and VAT compliance under OSS.
This article walks through each model in plain terms, with real-world context, practical examples, and just enough numbers to keep things grounded. By the end, you’ll know exactly how to build a logistics setup that works for your business — whether you’re just starting out or scaling across continents.
FBA: The Good, The Fees, and The Fulfillment
FBA is Amazon’s golden child — the logistics model that promises scale without the daily grind. You send your stock to Amazon’s warehouse empire, and they take it from there: storing it, packing it, shipping it, and even handling customer complaints when someone insists their Prime delivery was one hour late.
For new sellers, FBA is the easiest way to offer Prime delivery and skip the warehouse headaches. It gets you into Amazon’s good books quickly — complete with that shiny Prime badge and better Buy Box odds — while someone else deals with tape guns and tracking numbers.
Of course, it’s not all sunshine and Prime rainbows. Fulfillment fees, storage fees, and long-term storage penalties can sneak up on you if your inventory doesn’t move fast enough. For example, as of 2024, a standard-sized item (up to 500g) costs €3.83 to fulfill in the UK or €3.28 in Germany. If that item sticks around too long, expect to pay €2.72 per cubic foot monthly once it hits 271 days in storage — and €6.69 per cubic foot after 365 days. Ouch.
Monthly storage fees range from €21.10 to €29.30 per cubic meter depending on the season, and they climb during Q4. And don’t forget about the Inventory Performance Index (IPI). If Amazon thinks your inventory’s just hanging out collecting dust, you could be hit with restock limits that make Prime Day planning… challenging.
Still, if you keep things tight — monitor your IPI, rotate aged stock, and forecast demand like a pro — FBA can absolutely power a lean, mean, profitable machine. Just keep one eye on your inventory and the other on Amazon’s rate card.
FBM: Control Freaks, Branded Boxes & Bulky Stuff
FBM is where you take the wheel — and the packing tape. Instead of sending your products off to Amazon’s warehouses, you (or a trusty 3PL) handle the entire fulfillment process. That means storing, picking, packing, and shipping every order — along with answering customer queries and processing returns. If FBA is hands-off, FBM is all-hands-on-deck.
So why choose it? For starters, it gives you full control. If your products are oversized, handmade, fragile, or seasonally awkward, FBM gives you the freedom to ship them on your own terms. Want to use branded boxes, eco-friendly packaging, or handwritten thank-you notes? Go for it — Amazon won’t get in the way.
The trade-off? No Prime badge (unless you qualify for SFP), which can mean lower visibility and conversion rates. And while FBM isn’t as strict as SFP, you’re still playing by Amazon’s rules.
Here’s what you’ll need to keep in check:
- Order Defect Rate under 1%
- Late Shipment Rate under 4%
- Pre-Fulfillment Cancellation Rate under 2.5%
- Valid Tracking for at least 95% of orders
In Europe, you’re allowed to set your own shipping speeds — within reason. But don’t get too generous: if you regularly miss your own promises, Amazon might quietly extend your delivery timelines to protect the customer experience (and your ODR).
Bottom line: FBM gives you flexibility, but you need to back it up with solid logistics. With the help of tools like ShipStation, Zoho Inventory, or Linnworks, FBM can become a cost-effective, brand-friendly option that keeps you in control — and out of trouble.
SFP: Your Warehouse, Amazon’s Rules
Seller Fulfilled Prime — or SFP, for those fluent in Amazon acronyms — gives you access to that coveted Prime badge without giving up control of your fulfillment. It sounds like a dream setup: you ship from your own warehouse or a 3PL, your listings get that shiny badge, and customers get their orders fast. What’s not to love?
Well, SFP comes with strings. Or rather, spreadsheets. If you’re going to wear the Prime crown without FBA, you’ll need to prove you can keep pace. As of 2024, you’ll need to:
- Ship 99% of your orders on time
- Maintain a cancellation rate below 0.5%
- Use Amazon’s Buy Shipping for at least 99% of orders
- Offer nationwide one- and two-day delivery, including weekends
- Pass a rigorous performance trial
And if you slip? Amazon won’t hesitate to yank your Prime status.
That said, for sellers who’ve already built a high-performing fulfillment operation, SFP is a great way to maintain control without sacrificing visibility. You keep your own branding, customer service, and inventory strategy — all while showing up in Prime filters.
Just know what you’re signing up for. This isn’t for dabblers. It’s for the logistics-obsessed, the overachievers, and the sellers who already treat “on-time” like a sacred commandment. But if that’s you, SFP can deliver the best of both worlds.
Inside the Machine: Amazon’s Warehouse Web
Amazon’s fulfillment network in Europe is enormous — and growing by the month. With over 80 fulfillment centers across key countries, the goal is simple: get your products closer to the customer before they even hit “Buy Now.”
Warehouses in places like Tilbury (UK), Bad Hersfeld (Germany), Vercelli (Italy), and Madrid (Spain) aren’t just storage depots — they’re nodes in Amazon’s high-speed distribution web. But here’s what many sellers don’t realize: you don’t get to choose where your products go. Amazon’s algorithm handles that part, using demand forecasts and regional sales trends to auto-distribute your stock.
This has its perks (faster delivery times, Prime eligibility, higher Buy Box chances), but it also means you need to stay on top of your restock strategy. If your bestseller runs out in one country, Amazon won’t always shift it from another — and your listing can go out of stock regionally, even when you have inventory elsewhere.
Tools like the IPI dashboard, Restock Report, and Aging Inventory alerts inside Seller Central can help you avoid long-term storage fees and flag slow movers. The rule? If something’s been sitting in a warehouse for over 270 days, Amazon’s going to start charging you extra — and they won’t be subtle about it.
Oh, and if you’re wondering where Amazon might launch next? Keep an eye on where they’re building warehouses. Amazon opened its first Irish fulfillment center in Dublin in 2022, and just over two years later — in March 2025 — launched Amazon.ie as a full-fledged marketplace. Rumors of new FCs in Romania and Portugal are often the earliest breadcrumbs of a new marketplace rollout.
The Great Amazon Fulfillment Match-Up
So… FBA sounds great but pricey, FBM gives you control but needs serious logistics, and SFP is basically a gold-medal performance trial in shipping. How do you actually choose?
Start by looking at your products. If they’re lightweight, fast-moving, and you want the lowest-effort path to Prime, FBA is your new best friend. If they’re bulky, seasonal, or you already have your own warehouse setup, FBM might be the better call. And if you’re a logistics pro with an eye for detail, SFP lets you stay in control and still show up for Prime-hungry shoppers.
Here’s a secret: most serious sellers don’t pick just one. They mix and match. Use FBA to scale your core catalog, FBM for niche or oversized products, and SFP to keep full control over your premium listings. It’s less about picking a lane and more about building a stack.
No matter where you start, the goal is the same — consistent sales, happy customers, and a fulfillment setup that doesn’t make you want to throw your laptop out the window.
Conclusion: Pick Your Path, Then Be Ready to Pivot
If you’ve made it this far, congratulations — you now know more about Amazon fulfillment than most new sellers ever will. The key takeaway? There’s no single model that fits every business, product, or growth stage. And that’s actually a good thing.
FBA is perfect for fast-moving SKUs and hands-off operations, FBM gives you control and flexibility, and SFP rewards the logistics overachievers with visibility and Prime conversion power. But your fulfillment model doesn’t have to be static. In fact, it shouldn’t be.
Your ideal setup today might not be right in six months. A single product line can start with FBA and move to FBM as it matures. Seasonal inventory might demand a different strategy than everyday SKUs. The point is, flexibility is your friend — and sticking rigidly to one model can hold you back.
So keep things lean, monitor your IPI, rotate aged stock before Amazon makes you regret it, and always — always — have a backup plan for Q4. Talk to your 3PL, test your delivery windows, and don’t wait until you’re maxed out on restock limits to start thinking about alternatives.
Amazon logistics isn’t just about boxes and barcodes. It’s your engine for scale. Now that you’ve got the roadmap, it’s time to build something that moves — and keeps moving with you.
Fulfillment Recap: The Cheat Sheet Edition
Want the short version? Here’s how to make sense of Amazon fulfillment in one glance:
FBA: Let Amazon do the heavy lifting. Fast shipping, Prime badge, great for scaling — but watch those fees and inventory limits.
FBM: You’re in control. Great for oversized, seasonal, or custom products. Lower fees, but you’ll need a solid logistics setup.
SFP: The holy grail — Prime badge with full control. But it comes with high performance standards and zero margin for error.
Hybrid Strategy: Most pros use a mix of all three. FBA for speed, FBM for flexibility, SFP for brand control. Stay agile.
Going EU? Pan-EU FBA boosts reach but requires VAT in every country where inventory lives. OSS simplifies cross-border sales — but not storage.
Pro tip: Tools like Veeqo, Linnworks, ShipStation, and SimplyVAT make fulfillment (and compliance) far less painful.
Choose what fits now — then adapt as you grow.
