3PL comparison — written by a competitor, kept honest
ShipBob vs Red Stag: an honest comparison from a 3PL operator
Both are good companies built for different problems. ShipBob optimizes for a distributed, software-driven network. Red Stag optimizes for heavy, high-value products. We run a 32,000 sqft flat-rate warehouse in Houston. This page shows you how to tell which model fits your brand — with our own rates published, so at least one side of your comparison has real numbers on it.

Before you request a quote
Know the cost. Check the fit. Plan your first shipment.
Start with a small shipment or an established operation. There is no minimum volume. Tell us what you sell so we can confirm the handling, space and shipping you actually need.
What will my first month cost?
Example: 500 single-item orders under 5 lb × $2.00 full-service handling = $1,000. At $0.25 per mailer add $125; two full billable pallet-months add $50 and one inbound pallet adds $20. Total: $1,195 BEFORE postage, returns or extra work.
Examples use standard storage in the first three months. Long-stay pallet rates are $28/month in months 3–6 and $32/month after six months. Your written quote separates receiving, storage, handling, materials and shipping. Build your own estimate.
Why are there two handling prices?
Under 5 lb, Lean FBA is $0.50/unit and Lean FBM is $1.75/order when goods arrive pre-packed and ready to label. Full-service handling is $0.75/FBA unit or $2.00/FBM order; materials and postage are separate. These are service tiers, not automatic volume discounts.
Heavier items use different weight bands; over 15 lb or bulky items need a written quote. See the complete rate card.
Can you handle my products and platform?
Share your product type, packed dimensions and weight, sales platform and expected volume. Small batches and returns-only enquiries are welcome. Batteries, liquids, food, supplements, temperature-sensitive, hazardous or oversized items need acceptance and handling requirements confirmed before you ship.
For Shopify, Amazon, Walmart or another platform such as Amboras, tell us how orders and inventory are exchanged. The team confirms the connection or file workflow before onboarding; a platform name alone does not guarantee a supported integration.
How do I send inventory?
- Send your SKU list, dimensions, weights and carton/pallet count.
- Receive the written scope, rates and product-acceptance confirmation.
- Confirm account setup, labeling and receiving instructions with the team before dispatch.
- Send shipment details and tracking; agree the first prep job or order workflow.
Receiving location: 6117 Long Dr, Houston, TX 77087. Confirm inbound instructions before sending goods.
What about shipping and storage dimensions?
For a shipping estimate, send origin and destination ZIP codes, packed dimensions, weight, parcel count and desired delivery speed. Handling prices do not include carrier postage. Storage is charged only by carton or pallet. Bin and shelf storage is included in our standard pick-and-pack rate, with no separate charge. Send product dimensions and quantities so the team can confirm usable space, availability and the applicable carton or pallet storage rate in writing.
After you enquire: a real person from our Houston team replies within one business day, confirms any missing details and sends itemized pricing. You can ask for a written quote without booking a sales call. Unsure of volume? Select “Not sure yet” in the quote form.
The short answer
ShipBob fits brands that want inventory split across many warehouses for fast national delivery. Red Stag fits sellers of heavy, bulky, or high-value items that most 3PLs handle badly. A flat-rate regional 3PL like us fits sellers who want one warehouse, published pricing, no minimums, and a person who answers the phone.
We are not going to tell you two established competitors are bad at their jobs. They are not. They are enterprise operations with real strengths, and for some brands one of them is the right call — we say so plainly further down. What we will tell you is how their models differ from ours, and which questions expose the true cost of each before you sign anything.
One thing you will likely notice researching enterprise 3PLs: pricing usually arrives at the end of a sales conversation, not on a public page. Our rates are on this page and on our pricing page. That difference alone tells you a lot about which market each 3PL is built for.

What each model optimizes for
The three of us are not interchangeable vendors selling the same service at different prices. We run different operating models, and each model is the cheapest option for a different kind of seller.
ShipBob: the distributed network
ShipBob's core idea is splitting your inventory across multiple fulfillment centers so orders ship from the warehouse closest to the buyer. That shortens delivery times and cuts zone-based postage on high volumes. The trade-off is complexity: your stock is divided across locations, software decides where it sits, and, like most enterprise 3PLs, pricing is typically custom-quoted rather than published. The model earns its keep when you ship enough orders, spread widely enough, for network savings to outrun network overhead.
Red Stag: the heavy and high-value specialist
Red Stag built its operation around products most 3PLs dread — heavy, oversized, fragile, or expensive items where a picking error or a dropped carton costs real money. If you sell that kind of product, a specialist warehouse with handling processes designed for it is worth paying for — Red Stag is widely described as a specialist in exactly that niche. As with most enterprise 3PLs, expect a custom quote rather than a published rate card.
KAK: the flat-rate regional warehouse
We run one 32,000 sqft climate-controlled building at 6117 Long Dr in Houston, operating since 2024, serving 180+ ecommerce sellers. Our model is the opposite of a network: one location, published flat rates, no minimums, no contracts. Orders in before 2pm CT Monday through Saturday ship the same day. Houston's central position keeps ground transit reasonable in every direction, and one warehouse means one inventory pool, one dashboard, and no algorithm deciding where your stock lives.
| What to compare | ShipBob | Red Stag | KAK Sourcing |
|---|---|---|---|
| Operating model | Distributed network of fulfillment centers | US warehouses specialized in heavy and high-value goods | One 32,000 sqft climate-controlled Houston warehouse |
| Built for | High-volume DTC brands splitting stock across regions | Sellers of bulky, heavy, or fragile products | Sellers who want flat published rates and no minimums |
| How you learn the price | Sales process, custom quote | Sales process, custom quote | Published on this page and at /kak-price-list/ |
| Order pricing style | Varies by dims, zones, and services | Varies by handling requirements | Flat $2.00–$4.00 (custom over 15 lb) per order by weight tier |
| Minimums and contracts | Ask, and get the answer in writing | Ask, and get the answer in writing | None — month-to-month, start with one unit |
We do not publish competitors' rates because they are custom-quoted and change; treat any third-party number you find online as stale until their sales team confirms it in writing.
The questions that actually decide it
Serious buyers send us itemized RFQs, and the good ones ask the same fifteen things. Put this exact list to any 3PL you shortlist — including us. Here are our answers, with the published numbers.
| What buyers ask | Our answer |
|---|---|
| Do you take new brands with ~500 units? | Yes. No minimum volume, spend, or SKU count. Start with one unit. |
| Setup, onboarding, software, or account fees? | Setup fee: $0 — there isn't one. No contract, month-to-month; the KAK WMS dashboard is included with fulfillment. |
| Contract or cancellation penalty? | None. Month-to-month, leave any time. |
| Receiving cost and speed? | $20 per pallet ($5 per carton). Inventory in before the 2pm CT cutoff (Mon–Sat) is processed the same day. |
| Storage billing basis? | $25 per pallet, climate-controlled, billed monthly — you pay for the fraction of the month you actually use. Details at /storage/. |
| Lot and expiration tracking? | Available in our KAK WMS dashboard, with real-time inventory. |
| Per-order pick and pack? | $2.00 up to 5 lb · $2.75 (5–8 lb) · $4.00 (8–15 lb) · custom quote (over 15 lb). Standard packaging materials from $0.25. |
| Bundle pricing rules? | Bundles are picked and packed per order at the flat rates above. No forced preassembly. Kitting available if you want it, custom-quoted. |
| Branded inserts or custom packaging? | Custom-quoted — send your specs and you have the number in 24 hours. |
| Carrier rates: pass-through or markup? | Discounted USPS, UPS, and FedEx rates passed through at cost. No markup, no peak-season surcharges. |
| Returns fees? | $1.50 per return, inspection included. |
| Turnaround and cutoff? | Orders and inventory in before 2pm CT, Mon–Sat, ship or get prepped the same day. |
| Liability for errors and damage? | Insurance coverage up to $500,000 per occurrence. We are fully liable for our own handling. |
| Integrations? | Shopify, TikTok Shop, Walmart, eBay, BigCommerce, WooCommerce, Etsy, Magento, Amazon FBM. |
| Who do I talk to? | +1 832 759 1368 or sales@kaksourcing.com. Walk-ins welcome with 24h notice, Mon–Sat 9am–6pm CT. |
When a 3PL cannot answer one of these in a sentence, the honest translation is usually "it depends, and it will cost more than you think." Make them put it in the quote.
Our published rates
These are the rates we run the warehouse on, locked through Q1 2027. No tiers to negotiate, no fees hiding behind a demo call.
| Service | Rate | What is included |
|---|---|---|
| Amazon FBA prep | $0.75 per unit | FNSKU labeling and prep labor for units under 5 lb; polybags, bubble wrap and other materials are separate. |
| FBM / DTC fulfillment | $2.00 per order up to 5 lb | Pick, pack, ship; standard packaging materials from $0.25 |
| FBM, 5–8 lb | $2.75 per order | Same — flat rate by weight tier |
| FBM, 8–15 lb | $4.00 per order | Same |
| FBM, over 15 lb | Custom quote per order | Same |
| Pallet storage | $25 per pallet, billed monthly | Climate-controlled, 24/7 monitored |
| Receiving | $20 per pallet ($5 per carton) | Charged on every inbound |
| Returns processing | $1.50 per return | Inspection included |
| Postage | At cost | Discounted USPS/UPS/FedEx rates, zero markup |
Kitting, subscription-box assembly, and custom inserts are custom-quoted per job. Container devanning, LTL freight, and white-glove delivery are quoted per shipment at negotiated carrier cost — tell us your specs and you have the number in 24 hours via /get-a-quote/.
What a month actually costs at our rates
Here is the arithmetic for a typical DTC brand shipping 300 orders a month, all under 5 lb, holding 10 pallets of stock. No estimate ranges — these are the published rates multiplied out.
| Line item | Math | Cost |
|---|---|---|
| Pick, pack, ship — 300 orders under 5 lb | 300 × $2.00 | $600.00 |
| Receiving — 10 pallets inbound | 10 × $20.00 | $200.00 |
| Storage — 10 pallets, full month | 10 × $25.00 | $250.00 |
| Returns — 6 returns processed | 6 × $1.50 | $9.00 |
| Total service cost | $1,059.00 |
Postage comes on top, at our discounted carrier rates passed through with no markup — so your postage line is the carrier's price, not the carrier's price plus our margin. At 50 orders the pick-pack line is $100.00; at 100 orders it is $200.00. Storage bills monthly, so if pallets leave mid-month you stop paying mid-month.
Run the same exercise with any custom quote you receive. If a provider cannot give you numbers that multiply out this cleanly, you are not comparing prices — you are comparing sales pitches.
When ShipBob or Red Stag is the better call — and when we are
Honest guidance, because a client who picked the wrong model churns anyway. Choose the enterprise networks when their model is genuinely what you need:
- Pick ShipBob-style distribution when your volume is high enough, and spread widely enough across the country, that shipping from multiple warehouses meaningfully beats shipping everything from one central point — and you have the ops capacity to manage split inventory.
- Pick a Red Stag-style specialist when your catalog is dominated by heavy, oversized, or high-value items that need dedicated handling processes, and you are willing to pay specialist rates for specialist accuracy.
Choose a flat-rate Houston 3PL like us when:
- You are launching or scaling with anything from 1 to a few thousand orders a month and cannot justify enterprise minimums or onboarding overhead.
- You want to model your landed cost per order on a spreadsheet today, with published numbers, before ever talking to sales.
- You sell on Shopify, TikTok Shop, Amazon, Walmart, or eBay and want FBA prep at $0.75/unit and DTC fulfillment from $2.00/order under one roof — see our 3PL warehouse service.
- You value a 2pm CT same-day cutoff, monthly storage billing, and the ability to walk the warehouse floor with 24 hours notice.
- You want out of a bad fit without a cancellation penalty, because there is no contract to cancel.
