ShipStation 3PL Fulfillment Integration for Automated Order Processing

With Fulfyld connected to ShipStation, the orders you already manage there get fulfilled without your team buying a label. Orders flow from ShipStation to our 3PL, where they are picked, packed and shipped the same day when they are in by 1PM CT, and tracking plus stock counts write back into ShipStation on their own. The integration is free, your account manager can wire it up for you, and you can be live in under 7 days.

How it works

Ship same-day by 1PM without lifting a finger

Here is the path every order takes once your system is connected. No CSV uploads, no copying tracking numbers by hand.

01

Manage in ShipStation, we move the stock

The order moves from ShipStation to Fulfyld automatically over the API and lands in Shipedge, the warehouse system our team runs on.

02

Set your shipping rules once, not every order

Shipedge reads the shipping method on the order and maps it to the carrier service set up for your account. Each SKU is matched to the product on our shelves.

03

Catch wrong items before they reach the box

Our pick and pack process scans every item against the order before packing. A wrong SKU, variant or quantity is flagged and held, and the label prints only for the carrier service mapped to it.

04

Beat the 1PM cutoff and ship the same day

Orders in by 1PM Central ship the same business day, direct with USPS, UPS or FedEx, out of our dock in Madison, Alabama. No consolidators.

05

Stop copying tracking numbers by hand

The tracking number is written to the ShipStation order automatically the moment it ships, so your team copies nothing across.

06

Keep stock counts right on every channel

Every pick, restocked return and received shipment updates your on-hand count, and the new figure reaches ShipStation and every connected store within minutes.

Two-way sync

Stop overselling with stock synced in minutes

The fulfillment integration for ShipStation is a two-way, near real-time link: orders come across, and tracking and stock go back.

DataDirectionWhen
Orders in ShipStationShipStation → FulfyldPulled through the ShipStation API as they land
Shipping serviceShipStation → FulfyldRead per order and tied to a carrier at setup
Tracking numbersFulfyld → ShipStationWritten back to ShipStation the moment a parcel ships
Available inventoryFulfyld → ShipStationPushed to ShipStation within minutes of a change
Restocked returnsFulfyld → ShipStationAdded back to available stock after inspection
Product SKUsYou → FulfyldLoaded from your SKU template at onboarding; add new SKUs anytime

One stock pool feeds every store. Because ShipStation already pulls your stores together, a sale on any of them lowers the count Fulfyld reports back across all of them.

Setup

Go live with ShipStation in under 7 days, no code

Six steps from our onboarding checklist, no developer sprint. Moving your ShipStation fulfilment to Fulfyld takes less than 7 days.

1

Fill in one SKU and shipping sheet

You get an SKU and shipping method Excel template to fill in with your products and the shipping names you use. We load the SKUs and map each method to a carrier service.

2

Connect your system, then prove it with a test order

Authorise the ShipStation API, or let your account manager connect it. A one-unit test order then confirms orders land and tracking writes back cleanly.

3

Put your logo on every packing slip

Standard boxes, poly and bubble mailers, tape and void fill are included. Add your black-and-white logo to the packing slip, or send us your own custom packaging.

4

Master the dashboard in one 45-minute call

A 45-minute Zoom demo teaches you how to use the Shipedge dashboard, where orders, stock and returns sit in one place.

5

Ship in first stock with 2 free receiving hours

Submit a replenishment in Shipedge before your stock ships; your first receipt includes 2 hours of free receiving.

6

Pick a go-live day, Tuesday to Friday

Go-lives run Tuesday to Friday. From then on, orders in by 1PM CT ship the same business day.

Explained

Put a ShipStation 3PL through these 6 checks before you sign

ShipStation already pulls your store orders into one place, so your 3PL has to read from it cleanly and write back without drift. These are the six things to confirm, and how Fulfyld answers each.

Skip the CSV uploads and connect by API

ShipStation exposes an API for orders, shipments and tracking, so a connector trading scheduled files leaves a gap where the count drifts. Fulfyld runs on that API into Shipedge, so an order is in our queue seconds after it lands in ShipStation and corrections return the same way.

Orders held for review wait in the Fulfyld client portal until you release them, with CSV bulk upload kept as a backup.

Know why the API comes before MCP

An API is how two systems swap data: ShipStation sends an order, the 3PL returns tracking and stock. MCP is a newer standard for connecting AI tools to business software, usually built on top of an existing API, so the 3PL’s API is still the foundation.

Fulfyld runs on the ShipStation API. For a custom setup or a store without a ready connection, Fulfyld provides documentation for its open API.

Demand two-way, real-time sync or risk overselling

A one-way feed only sends orders out. The return leg — tracking, status and quantity within minutes — is what keeps ShipStation matching the shelf.

Fulfyld updates your ShipStation quantity within minutes of every pick, restocked return and received shipment, and pushes the same figure to every store you connect.

Confirm it writes a real shipment, not a label buy

Buying a label in ShipStation is not the same as a warehouse picking, packing and handing a parcel to the carrier.

That is exactly what Fulfyld does and writes back, so the ShipStation order and the customer email match what actually left the building.

Map bundles and gift notes before your first order

A bundle sold as one product has one SKU, but the warehouse picks every piece. A gift message sits in its own order field. A good integration maps the bundle to its component SKUs and the note to the packing slip.

Fulfyld maps bundles to their component SKUs, so each item is picked and counted on its own, and kits can be pre-assembled and stored as one SKU.

Make sure returns flow back, not just orders out

Each return should tie back to its original order, so your refund and your stock count match.

Fulfyld receives, inspects and restocks returns, and the corrected count reaches ShipStation within minutes.

Pricing

Know every fee before you sign, no surprises

Fulfyld folds the shipping label and postage, pick & pack with 5 free picks, and standard packaging into one flat per-order rate, and lists every other fee up front. No hidden fees.

FeeRate
ShipStation integration$0, unlimited stores
Flat per-order rateCovers postage and label, pick & pack of the first 5 items, and standard packaging
Extra picks$0.50 per item after the first 5
Receiving$40/hour; 2 hours free on your first receipt

Returns processing$3.50 first item, $0.50 each additional
Account management$0, dedicated account manager included

Example: at 501–1,000 orders a month, a 4–12 oz order with standard shipping (2–5 days) averages $7.74+, postage included. Every volume tier is on our 3PL fulfillment pricing page, and your exact rate comes back in one business day.

Volume, regions & products

Scale from 500 to 5,000+ orders a month

Three things decide whether a 3PL fits: how many orders you ship a month, where your customers are, and what you sell.

Pay less for storage as you grow

Fulfyld is built for brands shipping 500 to 5,000+ orders a month, and storage rates drop at higher volume tiers.

Ship from one hub with zero hand-offs

One warehouse, zero hand-offs, shipping direct with USPS, UPS and FedEx. No consolidators.

Promise 2-day delivery right at checkout

With our 2-day fulfillment, we let shoppers know which addresses we can reach within two days while they are checking out.

Sell beyond the US from the same stock

International shipping is available. At 501–1,000 orders a month, a 4–12 oz international order shows an average cost of $10.27+.

Ship fragile, heavy and kitted products too

Our fragile goods fulfillment builds packaging around each item with foam and bubble wrap, and big & bulky fulfillment moves heavy goods on forklifts and pallet jacks, strapped and labeled.

ShipStation prints labels and manages orders but does not run a warehouse; it exposes orders, shipments and tracking through its API, which is what a ShipStation 3PL integration connects to. A warehouse still picks, packs and ships. With Fulfyld that part is free: orders flow to us automatically, and tracking and stock write back to ShipStation.

The best 3PL for ShipStation reads from it cleanly and writes tracking and stock back without drift. Look for a free API connection; two-way sync of orders, tracking and stock; a published rate card; a same-day cutoff; and one account manager who knows your setup. Fulfyld checks all five. If you are also weighing ShipBob, ShipMonk or Red Stag, our 3PL comparison chart compares ten providers side by side.

Handing ShipStation orders to a 3PL is straightforward: once the API is connected, orders you manage in ShipStation flow to Fulfyld automatically, ship the same day when they are in by 1PM CT, and tracking writes back, so your team stops buying labels and packing boxes by hand.

Subscription box fulfillment is a Fulfyld service, and recurring orders you manage in ShipStation flow to Fulfyld automatically, with no manual uploads.

3PL services that come with the ShipStation integration include receiving and storage, pick and pack, same-day shipping with USPS, UPS and FedEx, kitting and bundles, returns processing, custom and branded packaging, and FBA prep. Every account also includes a dedicated account manager, quarterly cycle counts and 360° quality-control scans at no extra fee.

Fulfyld’s open API covers custom setups and stores without a ready-made connector, with documentation and an account manager through the build. Most ShipStation users do not need it, because the connection is already built and integrations are free and unlimited.

The ShipStation integration costs $0, and migrating to Fulfyld takes under 7 days. Onboarding covers loading your SKUs, connecting the API, a one-unit test order, a 45-minute dashboard demo and bringing in your first inventory, with 2 hours of receiving free.

Inventory syncs back to ShipStation in near real time, within minutes of any stock change: a pick, a restocked return, a received replenishment or a cycle-count adjustment. The same count reaches every store you have connected, which keeps you from overselling.

Every store you run in ShipStation can be fulfilled through one Fulfyld account at no extra cost. Connections are unlimited and included in your flat rate, and every store draws from the same inventory pool.

Put your ShipStation fulfilment on autopilot today

Connect ShipStation once, and Fulfyld handles the rest. Orders flow in automatically, ship the same day when they are in by 1PM CT, and tracking and stock write back to ShipStation.
