Why we added SpeedX to our carrier mix

Our published rate card has always passed discounted USPS, UPS, and FedEx rates through at cost — see the full breakdown on our 3PL pricing guide. SpeedX is a regional last-mile carrier we route eligible parcels through alongside those, on lanes where it beats the legacy options on price. It is not a separate service, a new fee, or a replacement for our fulfillment rate — it is simply a cheaper way to get the same package delivered, and we pass that saving straight to you.

Eligibility runs by lane and destination ZIP, not by account or plan: on any given label, our system routes to whichever eligible carrier — SpeedX, USPS, UPS, or FedEx — is cheapest for that specific package and destination. You never have to ask for it or configure anything.

The rate comparison

Based on our current SpeedX-eligible label volume, here is what the same package costs to ship through legacy national carrier rates versus SpeedX.

Carrier option	Typical cost per label	Notes
Legacy national carrier (standard published rates)	$7.00–$8.00	What most sellers pay outside a 3PL's negotiated rates
SpeedX, routed via KAK	~$4.75 average	Eligible lanes only; passed through at cost, no markup
Typical savings	32–41% lower	Up to 60% lower on select lanes

This is a shipping-label cost, separate from KAK's $2.75-and-up per-order pick-pack-ship fee. It does not replace anything on your invoice — it lowers the number that shows up as postage.

Carriers bill on dimensional weight, and SpeedX coverage varies by destination ZIP, so your real per-label number depends on your zones, weights, and box dimensions. Send us your SKUs for real numbers within 24 hours.

What the savings actually add up to

Using the midpoint of the legacy range ($7.50) against our $4.75 SpeedX average — a 36.7% reduction, in the middle of our stated 32–41% range — here is what that means at different order volumes. These are shipping-cost savings only, on top of whatever your KAK fulfillment fees already are.

Monthly orders	Legacy shipping cost	SpeedX shipping cost	Monthly savings	Annual savings
100 orders	$750	$475	$275	$3,300
300 orders	$2,250	$1,425	$825	$9,900
1,000 orders	$7,500	$4,750	$2,750	$33,000

Who this matters most for

Shipping is usually the single largest line on a DTC or FBM invoice — larger than pick-pack-ship, storage, and receiving combined for most light-parcel sellers. The savings here compound fastest for:

High-volume FBM and DTC sellers on Shopify, TikTok Shop, Walmart, eBay, or other marketplaces, where postage is charged per order.
Lightweight apparel, beauty, and accessories brands, where the shipping label is often a bigger cost than the product's pick-and-pack fee.
Sellers currently shipping through a carrier's own retail or standard published rates instead of a negotiated 3PL rate.

This runs alongside our standard rate card, not instead of it — see the full itemized breakdown on pricing or the printable price list.

SpeedX shipping FAQ

What is SpeedX, and why does KAK use it?

SpeedX is a regional last-mile carrier we route eligible FBM and DTC parcels through, alongside USPS, UPS, and FedEx. We added it because on many lanes it costs less than legacy national carrier rates, and we pass that saving straight through.

How much cheaper is SpeedX than legacy carrier rates?

Based on our current label volume, SpeedX averages about $4.75 per label versus $7.00–$8.00 for legacy national carrier rates — roughly 32–41% lower, and up to 60% lower on select lanes.

Is the $4.75 average guaranteed for every order?

No — it is our current average across SpeedX-eligible lanes, not a quote for a specific package. Actual cost depends on your zones, weights, and box dimensions. Send us your SKUs for real numbers.

Does KAK add a markup on top of SpeedX's rate?

No. Like the rest of our postage, SpeedX rates are passed through at cost with no markup added.

Is this separate from KAK's pick-pack-ship fee?

Yes. Our $2.75-and-up per-order rate covers picking, packing, and shipping labor and materials. SpeedX pricing is the shipping-label cost that sits on top of that, same as USPS, UPS, or FedEx postage would.

Does every shipment qualify for SpeedX rates?

No. Coverage depends on the destination ZIP and package characteristics. Our system automatically routes each label to whichever eligible carrier is cheapest for that specific shipment.

Do I need to request SpeedX, or is it automatic?

It's automatic. You don't need to configure anything — we route eligible labels to SpeedX as part of normal order processing.

How do I see what this means for my volume?

Send us your SKUs and ship-to mix and you'll have real, itemized numbers — including shipping — within 24 hours.
