Direct integration where the platform offers one, scheduled order feed where it doesn't — confirmed per channel before you commit.

One pool of inventory, every channel you sell on

Ecommerce fulfillment services are the layer between the checkout button and the doorstep. Your store takes the order; something still has to hold the inventory, find the SKU, pack it, buy the label, hand it to a carrier and push tracking back to the buyer — for every order, every day, across every channel you sell on. Past a few dozen orders a day that stops being a spare-room job and starts being an operation.

IDCEA runs that operation as your ecommerce 3PL: inventory received and stored by SKU, orders pulled in from your store and marketplaces into one pooled stock, picked and packed, shipped on a rate-shopped label, tracked back to the customer, and returns received and dispositioned. The work runs through partner warehouses in Southern California.

What's Included

Ecommerce Fulfillment Services We Provide

Inventory Receiving & Storage

Ecommerce warehousing and fulfillment from the dock in: inbound cartons or containers counted against your ASN, SKUs put away in bin, shelf or pallet locations sized to how they sell, and counts visible to you rather than reconciled at month end.

Ecommerce Order Processing

Orders come in from your store and marketplaces without anyone exporting a spreadsheet — by direct integration where the platform offers one, or by scheduled feed where it doesn't. Orders received before the daily cutoff are processed the same business day, stock permitting.

Pick & Pack Fulfillment

Ecommerce pick and pack against the order: SKU located, quantity picked and verified by scan, packed in a box sized to the contents, and the carrier label applied. Single-item, multi-item and bundle orders all run the same line.

Packaging & Kitting

Standard cartons and mailers billed on the materials used, or your own approved shipping-ready packaging, branded boxes, tissue and inserts where you supply them. Kitting and assembly for bundles, multi-packs and pre-built sets, so a bundle picks as one SKU instead of three.

Shipping & Tracking

Ecommerce shipping fulfillment across multiple carriers with rate shopping per order — service and price compared before the label is bought — then tracking numbers pushed back to your store so the buyer gets the update without you sending it.

Returns Processing

Ecommerce returns management: returns received against the original order, inspected, and dispositioned to restock, quarantine or disposal per your rules, with what came back and why reported rather than left in a corner.

How It Works

How Our Ecommerce Fulfillment Process Works

Connect

Your store and marketplaces are connected, SKUs mapped, and inventory set up as one pooled stock rather than a pile per channel.

Send inventory

Inbound freight or parcels are received, counted against the paperwork and put away by SKU.

Orders flow in

Orders import automatically as they're placed — no manual export, no copy-paste, no re-keying addresses.

Pick & pack

Each order is picked, scan-verified and packed; orders received before the daily cutoff go out the same business day when stock is on hand.

Ship & track

A rate-shopped carrier label is bought, the parcel is manifested, and tracking syncs back to your store and your customer.

01

Multi-Channel Ecommerce Fulfillment

Most brands don't sell in one place any more. The same SKU goes out through a Shopify or WooCommerce storefront, a marketplace listing, and increasingly a social storefront — and the fastest way to lose money on all three is to keep a separate pile of stock for each. Multi-channel fulfillment means one pooled inventory, one set of counts, and orders from every channel drawing on it.

We fulfill orders from the channels you sell on — Shopify, Amazon, eBay, Walmart, TikTok Shop, Etsy and WooCommerce among them. How a channel connects depends on the channel: some offer a direct integration, others are handled by scheduled order feed. We'll tell you which applies to yours before you commit, rather than calling everything an integration.

  • One inventory pool across every storefront and marketplace
  • Orders imported as placed, not exported by hand at the end of the day
  • Counts updated as orders ship, so channels stop overselling each other
  • Marketplace fulfillment run to each channel's shipping and tracking requirements
02

Ecommerce Warehousing & Inventory Management

Ecommerce inventory management is the unglamorous half of fulfillment and the half that decides whether the rest works. SKUs are received and put away in locations sized to how they move — fast movers in pick-face bins, slow or bulky stock in reserve racking — and counts are tied to locations rather than to a total sitting in a spreadsheet.

You see what's on hand, what's allocated to open orders and what's left to sell, which is what makes a reorder decision possible before a listing goes out of stock. For inventory that isn't shipping this month, our warehouse storage service holds it at bulk rates instead of in pick-face space you're paying a premium for.

Three numbers per SKU

Units physically in their locations right now.

What's left to sell — the number your channels should show.
03

Pick & Pack Fulfillment for Ecommerce Orders

Here is what actually happens between a customer clicking buy and the parcel arriving. The order lands in the queue with its SKUs and quantities. A picker is routed to the locations holding them and scans each item, so a wrong SKU is caught at the shelf rather than by the buyer. The order is packed in a carton or mailer sized to the contents — oversized boxes cost dimensional weight, undersized ones cost damage.

The carrier and service are rate-shopped for that parcel's weight, dimensions and destination, the label is bought and applied, the parcel is manifested onto the day's outbound, and the tracking number goes back to your store. Online order fulfillment is that loop, repeated accurately, thousands of times.

Ecommerce Returns Processing

Returns are part of ecommerce, not an exception to it. A returned parcel is received against the original order so you know which sale it belongs to, inspected against your criteria, and then dispositioned — back to sellable stock, into quarantine for review, or written off.

Not everything that comes back can be resold, and we don't pretend otherwise: opened, used or damaged goods are reported as what they are rather than quietly restocked. You get the disposition and the reason, which over a few months is the data that tells you whether the problem is the product, the listing or the packaging.

Where a return ends up

Restock
Back to sellable inventory when it passes inspection.
Quarantine
Held for your review when it's unclear.
Write-off
Opened, used or damaged — reported as such, not quietly restocked.

Ecommerce Fulfillment for Growing Brands

The point at which outsourcing makes sense is usually the point at which packing orders stops being the founder's job and starts being the reason nothing else gets done. The brands and businesses this page is written for:

Growing online stores outgrowing a garage, spare room or retail backroom
Established ecommerce brands consolidating fulfillment into one 3PL
Multi-channel and marketplace sellers running one catalog across several storefronts
Importers and manufacturers selling direct online
Brands running ecommerce alongside wholesale or retail out of the same inventory
06

What Ecommerce Fulfillment Costs

Fulfillment pricing isn't one number, and any 3PL quoting one before seeing your order profile is guessing. Cost is built from the pieces of work your orders actually create:

  • Receiving — by carton or container on inbound
  • Storage — by the cubic metres your SKUs occupy, per day, after the first free days
  • Pick and pack — per order, plus additional units in the same order
  • Packaging — standard materials, or your own branded materials
  • Shipping — the carrier's charge for that parcel, weight and zone
  • Returns and special projects — per return, or per project

Ecommerce Fulfillment in Southern California

The work runs through partner warehouses in the Los Angeles, Ontario and Riverside corridor. IDCEA staffs and coordinates the operation; we do not own the buildings, and we would rather say so than imply facilities we do not operate.

For an ecommerce brand the position matters on both ends: imported inventory clears the Los Angeles and Long Beach ports and goes into pickable stock without a cross-country leg first, and Southern California sits in the nearest ground zones for California and the western states — how many days that translates into depends on the carrier and service each order is shipped with.

The corridor

Los Angeles
Closest to the LA / Long Beach port complex.
Ontario
Inland Empire, on the I-10 and I-15 freight corridors.
Riverside
Inland Empire, for space and outbound lanes.
Partner warehouses, not buildings we own — IDCEA staffs and coordinates the operation.
Why IDCEA

Why growing brands run ecommerce fulfillment through IDCEA

No overselling

One pooled inventory behind every channel, so two storefronts can't both sell the last unit.

Rate shopping on every order

Carrier and service compared per parcel on weight, dimensions and destination before the label is bought.

Close to western demand

Southern California sits in the nearest ground zones for California and the western states — fewer zones crossed on most domestic orders.
