3PL Order Fulfillment Integration for 3dcart, Automated End to End

Link your 3dcart (now Shift4Shop) store to Fulfyld once and order handling stops being a task on your desk. Every order routes straight to our 3PL, where it is picked, packed and shipped the same day when it is in by 1PM CT, and the tracking and stock counts flow back to your store on their own. There is no charge for the integration, your account manager can set it up for you, and you can be live in under 7 days.

How it works

Push every 3dcart order to the floor and watch it clear

Here is the route an order follows once your 3dcart store is connected, with no exports and no tracking copied by hand.

01

List on 3dcart, and we pick it up from the order

The order reaches Fulfyld over the 3dcart REST API and lands in Shipedge, the warehouse system our team runs on, so nothing is rekeyed.

02

Match each shipping choice to a carrier once

Shipedge reads the shipping choice on the order and maps it to the carrier service on your account, and each SKU points to the product on our shelves.

03

Stop a wrong pick before it is boxed

Every item is scanned against the order before packing, so a wrong SKU, option or count is pulled and held and only the matched service label prints.

04

Clear the 1PM cutoff and dispatch that day

Orders in by 1PM Central leave the same business day on USPS, UPS or FedEx from our Madison, Alabama dock, with no consolidator in the chain.

05

Write tracking to the order on its own

The tracking number is written to the 3dcart order the moment it ships, so your team never pastes one in.

06

Keep one stock figure across channels

Each pick, restocked return and received shipment updates stock on hand, and the new figure reaches 3dcart and every connected channel within minutes.

Two-way sync

Stop the storefront selling past the shelf

The 3dcart fulfillment integration keeps a two-way, near real-time sync: orders arrive, and tracking and stock go back within minutes.

DataDirectionWhen

Restocked returnsFulfyld → 3dcartReturned to available stock once inspected
Your SKUsYou → FulfyldLoaded from one template at setup; add new SKUs in the dashboard anytime

One stock pool supplies every channel. Run Amazon, your own site or a marketplace beside 3dcart, and a sale on any of them trims the figure on all of them.

Setup

Live on 3dcart in under 7 days, no build needed

Six onboarding steps, no dev cycle to schedule. Moving your 3dcart fulfilment to Fulfyld takes less than 7 days.

1

Pass us one SKU-and-shipping sheet

You complete one SKU and shipping template with your products and the shipping options your 3dcart store runs. We import the SKUs and map each option to a carrier.

2

Connect the API, then run a test order through

Create 3dcart API credentials, or let your account manager connect the store. A one-unit test order confirms orders, labels and tracking travel end to end.

3

Brand the packing slip

Boxes, poly and bubble mailers, tape and void fill come as standard. Add your black-and-white logo to the packing slip, or ship us your own packaging to run.

4

Get to know the dashboard in 45 minutes

A 45-minute Zoom session runs you through the Shipedge dashboard, where orders, stock and returns sit on one screen.

5

Bring in first stock, receiving hours on us

Submit a replenishment in Shipedge before your stock reaches the dock; the opening receipt carries two free hours of receiving.

6

Set a go-live day, Tuesday to Friday

Go-lives run Tuesday through Friday, and from then 3dcart orders in by 1PM CT ship the same business day.

Explained

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

3dcart hands you a REST API, and your 3PL should lean on it, not a file routine. Here are the six points worth confirming, and how Fulfyld answers each.

They connect on the 3dcart API, not a nightly file

3dcart exposes a REST API for orders, inventory and shipping, so a 3dcart 3PL fulfillment integration can run on it live; a connector trading scheduled files leaves a gap to oversell. Fulfyld runs on that API into Shipedge, so an order hits our floor seconds after checkout and corrections return the same way.

Anything held for a closer look sits in the Fulfyld client portal for you to release, with CSV bulk upload kept in reserve as a fallback.

They explain why an API beats a plugin to mind

An API trades data live in both directions, while a plugin is one more component to patch and one more place the sync can stall.

Fulfyld’s 3dcart link runs on the API, and for a customised build or a channel without a ready connector, Fulfyld’s open API covers it, with docs and an account manager.

They run a two-way link, not just orders outward

A feed that only sends orders out is half a sync. The return leg — tracking, status and quantity within minutes — is what keeps the storefront from selling stock that already left.

Fulfyld refreshes 3dcart stock within minutes of each pick, restocked return or received shipment, and writes tracking as the parcel ships.

They keep stock steady across your channels

Sell the same item on 3dcart and a marketplace and they draw on one shelf, so a 3PL that cannot hold one figure across them oversells on the busiest.

Fulfyld keeps a single figure per SKU and pushes it to 3dcart and every connected channel within minutes.

They line up product options and bundles early

A 3dcart product with options, or a bundle sold as one, ships on a single line while the warehouse picks each part, and missing that miscounts fast.

Fulfyld maps product options and bundles to their component SKUs, so each is picked and counted on its own, and kits can be pre-assembled.

They cycle returns back, not only orders out

A 3dcart return should tie to its original order, so your refund and your stock figure agree.

Fulfyld receives, inspects and restocks returns, and the corrected figure reaches 3dcart within minutes.

Pricing

Read every fee up front, none tucked away

Fulfyld rolls the shipping label and postage, five free picks and standard packaging into one flat per-order rate, and lays out every other fee up front. No hidden fees.

FeeRate
3dcart 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
Storage (501–1,000 orders/mo)Small bin $2.20, regular bin $3.50, X-large bin $5.25, pallet $28.00 per month; cheaper as volume grows
Returns processing$3.50 first item, $0.50 each additional
Account management$0, dedicated account manager included

As a guide, at 501–1,000 orders a month a 4–12 oz standard (2–5 day) order runs near $7.74+ with postage in. Every tier is published on our 3PL fulfillment pricing page, and the rate eases as you scale.

Volume, regions & products

Scale from 500 3dcart orders a month to 5,000+

Three things decide whether a 3PL fits a 3dcart merchant: your monthly order count, your buyers’ locations, and your product mix.

Pay less to store as orders grow

Fulfyld is built for brands shipping 500 to 5,000+ orders a month, and per-bin storage steps down at higher tiers, so scaling up does not inflate your warehousing.

Ship from one hub, nothing handed off

One warehouse, no hand-offs, straight onto USPS, UPS and FedEx, with no consolidator between you and the buyer.

Offer a true two-day choice at checkout

From one national hub, transit tightens, so a real two-day delivery option can appear at your 3dcart checkout rather than a hopeful guess.

Reach international buyers from one shelf

Cross-border orders are no problem. At 501–1,000 orders a month, a 4–12 oz international order shows a rate you can read before you commit.

Cover fragile, heavy and kitted goods as well

Our fragile goods fulfillment wraps each item in foam and bubble wrap, and big & bulky fulfillment takes the oversized lines many 3PLs refuse.

The benefits

Get a whole 3PL team behind your 3dcart store

Get connected free with an API key set up

Link your 3dcart store with an API credential, or let your dedicated account manager connect it. Either way it costs $0.

Work with one manager who knows your setup

A named specialist on your account, with you from day one of onboarding and well beyond it.

Turn 3dcart returns back into stock

Returned units are inspected and restocked, and the corrected figure writes back to 3dcart on its own. Reverse logistics is built into the service.

Depend on a 99.9% pick rate

A 99.9% pick rate, two-day dock-to-stock receiving and 360° quality-control checks are standard on every account.

Beyond the integration

Scale into kitting, FBA prep and subscriptions

Hand every 3dcart order over at one flat rate

Flat-rate pick, pack and ship on every order your 3dcart store sends across. No hidden fees.

3dcart does not pick or ship on its own; it opens orders, products and stock through its REST API, which is what a 3dcart 3PL integration connects to. The physical work still falls to a warehouse. With Fulfyld it is free: orders flow to us automatically, and tracking and stock sync back to 3dcart.

It depends on who ships, and the best 3dcart fulfillment integration is the one that matches that. Pack orders yourself and a label tool is enough; as volume rises, you want a partner that runs on the 3dcart API, writes tracking to the order and keeps one figure across your channels.

Two ways. You pick, pack, ship and write tracking yourself, or you hand it to a 3PL like Fulfyld that pulls the order over the API, ships same day when it is in by 1PM CT, and writes tracking back for you.

Yes — it is a Fulfyld service, and 3dcart is one of the platforms we ship recurring boxes from, stored and kitted each cycle.

Receiving and storage, pick and pack, same-day shipping by 1PM CT, tracking writeback, returns handling and a dedicated account manager, all under one flat per-order rate.

Yes. For customised builds and channels without a ready connector, Fulfyld’s open API fills in, with documentation and an account manager through the work.

The 3dcart integration costs $0, and moving to Fulfyld takes under 7 days. Onboarding loads your SKUs, maps shipping options, connects the API, and runs a one-unit test order with a 45-minute dashboard session.

Within minutes of any stock change — a pick, a restocked return or a received shipment — and the same count reaches every other channel you connect.

Yes. Several 3dcart stores, plus other channels, connect to one Fulfyld account at no extra cost, unlimited and inside your flat rate.

Put your 3dcart fulfilment on autopilot today

Link the store once and leave the rest to us: orders arrive on their own, ship the same day when in by 1PM CT, and tracking and stock post back to 3dcart.
