SFP Shipping Optimization
Keep your Amazon Prime badge. Ship from your own warehouse.
FBA Fees Are Growing Faster Than Your Margins
Amazon FBA is convenient, but the fee increases are relentless. Fulfillment fees, storage fees, removal fees, long-term storage penalties — they compound annually. Seller Fulfilled Prime offers a path to keep the Prime badge while shipping direct, but the operational requirements are strict enough that most sellers struggle to qualify and maintain eligibility.
FBA fees add up faster than most sellers track
The visible fulfillment fee is only the start. Storage fees, peak surcharges, aged inventory penalties, and removal costs make FBA's total cost significantly higher than the line-item rate.
SFP's on-time delivery requirements are unforgiving
To qualify for and maintain SFP, Amazon requires 99%+ on-time delivery. Without the right carrier mix and shipping strategy, sellers lose their eligibility — and with it, their Prime badge.
Without SFP, non-Prime listings get buried in search
Prime is the default filter for most Amazon shoppers. Non-Prime listings see significantly lower impressions and conversion rates — making FBA feel like the only viable option.
The process, top to bottom.
We audit your current shipping performance
We review your delivery times, carrier performance data, and current costs across your Amazon fulfillment mix to identify whether SFP is viable for your business.
We build your SFP-compliant carrier strategy
Meeting Amazon's SFP delivery requirements demands a specific carrier strategy. We configure the right carrier mix — with DHL, UPS, FedEx, and USPS optimally allocated by zone and speed — to keep your on-time rate above 99%.
You ship Prime at negotiated rates without FBA
With SFP active and a compliant carrier strategy in place, your Prime orders ship directly from your warehouse at Kadima's negotiated carrier rates — keeping the badge without the FBA fee structure.
The deliverables, in plain English.
Eliminate FBA fees on eligible orders
Fulfillment, storage, and accessorial fees that go to Amazon can be replaced with your direct warehousing costs plus Kadima's carrier rates — typically at lower total cost per unit.
Maintain 99%+ on-time delivery
Our carrier optimization and monitoring keeps your delivery performance above Amazon's SFP eligibility threshold — so you don't lose the badge you worked to earn.
Carrier mix optimized for SFP compliance
We route each order through the carrier and service level most likely to deliver on time for that destination — prioritizing compliance over everything else.
Keep direct control over your inventory
Your inventory stays in your facility or our 3PL network. No minimum Amazon FBA inventory requirements. No aged inventory penalties.
Combined with negotiated rates
SFP shipments go out at Kadima's carrier rates — including DHL reseller pricing and GPO volume discounts — lowering your per-shipment cost below what Amazon charges for FBA.
Monitoring and alerts
We monitor your SFP performance metrics continuously and flag any delivery trends that could risk your eligibility before they become a compliance problem.
Every month you wait, the meter keeps running.
Most clients see meaningful savings within the first invoice cycle. The audit itself is free — the only thing you're risking is finding out you've been overpaying. Then you decide what to do with the number.
Who this service fits best.
Prime-dependent listings
Prime is the default filter — losing the badge tanks impressions. SFP keeps it without the FBA fee structure.
FBA fees ate the margin
Fulfillment + storage + aged-inventory penalties have outgrown your contribution margin. SFP rebuilds it.
Existing warehouse ops
You already pick and pack reliably. SFP just layers Amazon's delivery requirements on top — we handle the carrier strategy.
What people ask before signing up.
What is Seller Fulfilled Prime (SFP)? →
Seller Fulfilled Prime is an Amazon program that lets sellers display the Prime badge on listings they ship directly from their own warehouse. Orders must meet Amazon's two-day delivery requirements and 99%+ on-time shipping rate to maintain eligibility.
Is SFP right for every Amazon seller? →
SFP works best for sellers with established warehouse operations, reliable carrier access, and products that aren't time-sensitive to store in Amazon's network. We run an analysis first to confirm whether the economics work for your specific product and order mix.
What carriers does Amazon accept for SFP? →
Amazon accepts DHL, UPS, FedEx, USPS, Amazon Shipping, and approved regional carriers for SFP. The right carrier mix depends on your shipping zones and delivery speed requirements. We configure this specifically for your product and destination distribution.
What happens if my on-time rate drops below Amazon's threshold? →
Amazon monitors SFP performance continuously and can suspend eligibility if your on-time rate drops below their threshold. We track your delivery performance in real time and alert you before performance issues reach a suspension risk level.
Can I use SFP alongside FBA? →
Yes. Many sellers run a hybrid model — SFP for products where they have control over the supply chain, FBA for products where Amazon's fulfillment network speed is essential. We help you identify which products belong in which channel.
