Consumer Electronics & Wearables Fulfillment, Tracked by Serial Number

KSP stores and ships consumer electronics, wearables and the chargers, cases and bands that sell with them. On serialized SKUs we scan the serial when a unit reaches our dock and again when it's packed, so every order record names the exact device in the carton. Devices with small lithium cells built in ship by ground from the same floor, and orders in by 2 PM CST leave the same day.

What Is Electronics Fulfillment?

Electronics fulfillment is storing a brand's devices and accessories and shipping them to customers, Amazon and retailers, while recording which serial number went to which order. It also covers the shipping rules for lithium cells inside devices and the inspection of returned units before they go back on sale.

Three things set it apart from shipping other products. Each device has its own identity, so a 3PL has to know which unit left on which order. Most wearables, earbuds and smart home devices carry a lithium cell, which decides how they ship. And return rates on electronics are high enough that the returns bench decides a good share of your margin.

We ship smartwatches and fitness bands, earbuds and headphones, smart home devices, speakers, and the phone and laptop accessories, chargers and cables sold with them.

Serial Numbers Recorded at the Dock and at the Pack Bench

When a customer files a warranty claim, your support team needs one answer fast: which unit did this person get? Our Logiwa WMS keeps that record at every step a serialized device passes through.

  1. Receiving

    Associates capture each serial with handheld RF scanners, and the WMS validates it against your ASN before the unit is put away. If a serial is missing, the receipt stops at the dock, before the problem can reach a customer.

  2. Pick and pack-out

    The unit barcode is checked at the pick and again at pack-out, so the serial on the order record is the serial in the box.

  3. Outbound manifest

    Serials are linked to the packing slip and shipping documents, which gives your support team a clean answer for every warranty claim and every delivery dispute.

  4. Accessories without serials

    Cables, cases and bands that carry no serial are tracked by SKU like the rest of your catalog, and the order record lists them next to the device they shipped with.

Lithium Batteries: Which Devices We Take

Most device buyers ask about batteries first. KSP doesn't take hazmat, so where the cell sits decides whether a SKU ships from our building.

Battery setupExamplesWhere it lands
Small cells built into the device

Smartwatches, fitness bands, earbuds, Bluetooth speakers, smart home sensors

In. Set up SKU by SKU at onboarding and shipped by ground as non-hazmat.

Spare battery packed in the box

A device sold with an extra battery inside the retail package

Reviewed SKU by SKU before we accept it. Out if its shipping classification is hazmat.

Batteries sold on their own

Power banks, replacement batteries, loose battery packs

Out. These need a warehouse with a hazmat program.

We settle this before your first inbound truck, from the battery details on your manufacturer's spec sheet. That way no pallet arrives at our dock with a SKU we can't ship.

Empty-Box Claims and Shrink: The Records Behind Each Answer

On every device order

  1. "The box arrived empty"

    Every packed carton passes certified scales before its label prints, so the weight it left with is on file next to the tracking number.

  2. "I got the wrong unit"

    The serial scanned at pack-out shows which device went into that carton.

  3. Camera footage

    CCTV is recorded around the clock and kept for 90 days, so footage from the pack date is still there when a claim comes in weeks later.

  4. Who handles your stock

    Our staff are background-screened and credit-checked, and electronic door access controls who enters the building. High-value devices go in our floor-to-ceiling security cage.

  5. If a unit goes missing

    If we lose or damage a unit, we pay its cost. Signature-required delivery and declared value are available per order for your most expensive SKUs.

Devices, Accessories and Launch Bundles From One Inventory

A device brand sells the hardware and a long tail of things that go with it. Bundles of the two are where wrong-part orders tend to happen, so they're built and checked in the same building that ships them.

  • Launch and gift bundles

    Device plus case, charger, band or cable, built on our 50,000 sq ft kitting floor. Each bundle is checked against its bill of materials with photo QC before the box closes, so a USB-C charger never ends up in a bundle for a Lightning model.

  • Short shipments caught at the dock

    Component receipts are counted against the bundle's bill of materials. When a supplier short-ships cables or cases, your account manager tells you before the build starts, with how many complete bundles we can still build.

  • Bundles sell like any SKU

    A finished bundle gets its own SKU and sells through Shopify, Amazon, Walmart or retail EDI. Selling somewhere else? Any platform connects through Logiwa or our own API, and a new connection can be built in as little as a week.

  • Device and accessory stock in one view

    The client portal shows on-hand stock by SKU, so you can see when chargers or bands are about to hold up your bestselling device. Larger build programs are covered on our kitting and assembly page.

Returned Devices, Checked Against the Unit That Shipped

Some returns come back with an older or broken unit inside the box, and restocking one means selling a bad device to the next customer. Because the serial stays attached to the order, a return resolves against the exact device that left our building.

  1. Match the serial

    The returned unit is matched to the unit that shipped on that order. A unit that never left our warehouse can be refused instead of restocked.

  2. Inspect

    Associates check the seal, the accessories in the box, the device's condition and the retail packaging.

  3. Grade

    Each return gets a condition grade, so a scuffed box and a cracked screen don't land in the same bin.

  4. Restock and report

    Sellable units go back to available stock, and you get a report of every return and its condition.

Our serial records are explained step by step in our guide to 3PL serial number tracking. Here's how one technology and healthcare retailer described the floor after a visit.

Believe me when I say that I've seen a lot of warehouses. I would eat off the floor at KSP and put their customer service up against anyone. The process/flow, pride, discipline, and efficiencies had militaristic flavor. Top notch. We really look forward to building a huge business together!

Amazon Prep and Retail Packaging Rules for Devices

The same pair of earbuds ships three different ways depending on who ordered it. All three draw on one inventory, so a retail PO doesn't empty the shelf your website sells from.

Your vendor setup with each retailer

With Amazon no longer offering its own prep, more device brands send FBA prep to their 3PL. Here's what changed when Amazon ended FBA prep, and how we handle retailer POs, EDI and routing guides.

Device Launches, Preorders and Holiday Demand

A new model announcement can put a month of orders in the queue before the first unit lands. We hold preorders and release them on your street date, so nobody gets a device early and nobody waits past launch day.

When orders jump, 135+ Locus robots carry totes through picking, so associates keep picking and scanning instead of walking aisles. Serial capture stays on at launch volume, which means your warranty records are complete from the first order. Orders in by 2 PM CST ship the same day, and ground delivery reaches any US address in 1 to 3 days.

Launch bundles your plan calls for are built before the rush, so peak orders pick as single finished units. If something goes wrong on launch day, your account manager responds within our 2-hour issue SLA.

What Sets the Cost of an Electronics Program

Unit value, serial capture and return rate move the cost of an electronics program more than order count alone. We walk you through an invoice and your program line by line before you sign, and the 3PL fee checklist lists the fee lines worth comparing across quotes.

Receiving with serial capture

Scanning a serial on every unit takes longer than counting cartons, so the share of your SKUs that carry one changes receiving labor.

Packing retail-boxed devices

Your packing spec says whether a retail box ships inside a shipping carton or on its own. The shipping carton keeps the retail box clean enough to resell or give as a gift. Cartons are weighed and measured before the label prints, so you pay postage on the real size.

Bundles and accessories

Launch and gift bundles are priced per finished unit.

Returns

Inspection and grading scale with your return rate, which for some device brands is the biggest line after postage.

Electronics Fulfillment FAQ

Does KSP record serial numbers on the devices it ships?

Yes, on every SKU that carries a serial. We scan it at receiving and at pack-out and link it to the shipping documents, so each order shows which unit shipped.

Can you ship devices with lithium-ion batteries?

Yes, when small cells are built into the device. Those SKUs are set up one by one at onboarding and ship by ground as non-hazmat. We don't take power banks, standalone batteries or anything classed hazmat.

How do you know a returned device is the one you shipped?

The serial stays attached to the original order, so each return is matched to the unit that shipped. A unit that never left our warehouse can be refused.

What happens if a customer says the box arrived empty?

We pull the carton weight recorded before the label printed and the serial scanned at pack-out. CCTV from that day is kept for 90 days.

Can you build bundles with chargers, cases and bands?

Yes. Bundles are built on our kitting floor from a bill of materials, photo-checked before the box closes, and sold as their own SKUs.

Do battery-powered devices need extra steps before going to Amazon FBA?

Yes. Amazon reviews battery products under its own dangerous goods process, from documents your Seller Central account uploads. We handle the labeling, bundling and case prep.

How do you protect high-value devices in storage?

High-value stock goes in our floor-to-ceiling security cage, staff are background-screened and credit-checked, and if we lose or damage a unit, we pay its cost.

Can you hold preorders until a release date?

Yes. Preorders are held and released on the date you set, then ship with the same-day cutoff.

Can You Prove Which Unit Each Customer Got?

Tell us what you sell and where. We'll show you how serial records, battery setup and returns would work for your catalog, and what fulfillment would cost.

  1. Answer five quick questions about what you ship and where you sell, with rough numbers.
  2. A KSP rep gets in touch within 1 business day to set up a short call and hear what you need.
  3. We build a handling plan and a quote around your devices, then walk you through both line by line.
