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.
How KAK connects to your sales channels
We connect natively to the platforms most of our 180+ sellers already run on, so orders import automatically and nothing has to be typed in by hand. Connect one channel or five — inventory stays pooled across all of them in the KAK WMS dashboard, updated in real time.
- Amazon — FBA prep and FBM order fulfillment, native connection. See our Amazon integration details.
- TikTok Shop — native order import and automatic tracking push-back. See our TikTok Shop integration details.
- Shopify — native connection, real-time inventory sync.
- Walmart — native connection for marketplace order fulfillment.
- WooCommerce, BigCommerce, Etsy, Magento, eBay — supported connections for pick-pack-ship.
Selling somewhere that isn't on this list? We build a custom integration — tell us your platform and we'll scope it, usually within 24 hours.
How an order actually moves once you're connected
The flow is the same no matter which channel the order came from.
- A customer places an order on Shopify, Amazon, TikTok Shop, Walmart, or any connected channel.
- The order imports into the KAK WMS automatically — no manual entry on your end.
- Our team picks, packs, and ships it from our 32,000 sqft, 24/7-monitored Houston facility, same day if it's in before the 2pm CT cutoff, Monday through Saturday.
- The tracking number pushes back to your store automatically.
- Inventory updates in real time across every connected channel, so you don't oversell a SKU that just sold out on a different platform.
What connecting your store costs
Nothing extra. There's no setup fee to connect a sales channel — you pay our standard per-unit and per-order rates for the work itself, the same rates whether an order comes from one channel or five.
| Service | Rate |
|---|---|
| Amazon FBA prep (FNSKU labeling, polybag, bubble wrap, cartonization) | $0.75/unit under 5 lb; materials separate |
| FBM / DTC order fulfillment — up to 5 lb | $2.00/order |
| FBM / DTC order fulfillment — 5–8 lb | $2.75/order |
| FBM / DTC order fulfillment — 8–15 lb | $4.00/order |
| FBM / DTC order fulfillment — over 15 lb | Custom quote |
| Pallet storage, climate-controlled | $25/pallet, billed monthly |
| Receiving | $20/pallet ($5/carton) |
| Returns processing (inspection included) | $1.50/return |
Postage runs at discounted USPS, UPS, and FedEx rates passed through at cost, no markup. Full rate card: KAK price list · pricing overview.
Our per-unit and per-order rates hold steady through peak season — no surcharges in Q4 or any other month, no matter which channel the order came from.
What a multichannel month actually costs
Say you sell on Shopify and TikTok Shop, ship 300 orders a month that all come in under 5 lb, keep 10 pallets in storage, and receive one inbound shipment of 20 pallets that month.
- Fulfillment: 300 orders × $2.00 = $600
- Storage: 10 pallets × $25 = $250
- Receiving: 20 pallets × $20 = $400
- Total: $1,250 for the month — no setup fee, no contract
Add Amazon FBA prep at $0.75/unit if you're dual-listing on Amazon, or drop the storage line if you're running lean inventory. Get an exact number for your SKU mix off the published rates above.
Questions buyers ask before they connect a store
These come up on nearly every RFQ we get. Straight answers, in order.
- Is there a setup or integration fee? No. Connecting a channel is free — you only pay the per-unit or per-order rates above.
- Do you work with new brands just getting started? Yes — there's no minimum order volume, so you can start with a single unit or a small first shipment.
- Is there a contract? No. Everything is month-to-month, no minimum order volume or spend.
- Does real-time sync actually stop overselling? Yes — inventory is pooled across every connected channel in the KAK WMS, and it updates in real time.
- Do you track lot numbers and expiration dates? Yes, lot-number and expiration-date tracking is available.
- Does tracking push back to my store automatically? Yes, once an order ships, the tracking number syncs back — no manual entry on your end.
- What if my products are already sitting in Amazon FBA? No problem — FBA prep and FBM fulfillment both run through the same KAK WMS dashboard.
- What's the cutoff for same-day dispatch? 2pm CT, Monday through Saturday. Anything in after that ships the next business day.
- Who do I call if an order breaks? Call +1 832 759 1368 or email sales@kaksourcing.com. Walk-ins welcome with 24 hours' notice, Monday–Saturday 9am–6pm CT.
