Can I connect Plentymarkets to my fulfilment partner without having to enter data manually?

Yes. With an integration platform or a suitable standard connection, orders are automatically sent from Plentymarkets to your fulfilment partner, and shipping status and inventory information are automatically returned, so no one has to retype any data.

Will my inventory in Plentymarkets remain accurate across all channels?

That’s exactly the goal: the inventory reported by your fulfilment partner is automatically synced back to Plentymarkets. Since Plentymarkets often manages multiple channels, this helps you avoid overselling on any sales channel.

Isn't a native plugin or my 3PL's portal enough?

For a single fulfilment partner with a good integration and a limited volume, that may be perfectly sufficient. However, as soon as you start combining multiple partners or warehouses, want to be able to switch partners, or want to connect an ERP or accounting system, an integration platform generally becomes more reliable and easier to maintain.

Can I add a second fulfilment partner or marketplace later?

Yes. That’s the advantage of an integration platform: you connect Plentymarkets and your fulfilment provider once, and later you can add a second fulfilment partner, a marketplace (such as Bol or Amazon), or an ERP system without having to rebuild your existing integration.

How much does it cost to integrate Plentymarkets with fulfilment?

That depends on the method you choose and on the number of data streams, partners, and channels. Doing it manually is “free” but very time-consuming; a native plugin or portal often has limitations; a platform typically has a fixed structure plus costs that scale accordingly.

Connecting Plentymarkets to Fulfilment: Here's How

Short answer: There are four ways to connect Plentymarkets to your fulfilment partner or 3PL— manually, with a native plugin/connection, through a 3PL portal, or via an integration platform. Which option is best depends on your order volume, the number of sales channels, and whether you want to centralize your inventory.

Plentymarkets is a multichannel system: it often serves as your central source for inventory and orders across multiple channels. As soon as an external fulfilment partner (3PL) handles your shipping, orders must be sent to the warehouse, and shipping status and inventory levels must be updated—automatically, without manual data entry. Manual work takes time, leads to errors, and causes overselling. Below, you’ll find an honest overview of the available options and when to choose each one.

What data should you actually link?

Before you choose a method, it’s helpful to know exactly what needs to be exchanged between Plentymarkets and your fulfilment partner:

Data	From	To	Why
Orders	Plentymarkets	Fulfilment / 3PL	The warehouse can pick and ship orders immediately
Shipping Status & Track & Trace	Fulfilment / 3PL	Plentymarkets	The customer and the administration see the correct status
Inventory	Fulfilment / 3PL	Plentymarkets	Prevent overselling across all channels
Items (SKUs)	Plentymarkets	Fulfilment / 3PL	Manage product data once

The Four Ways to Integrate Plentymarkets with Fulfilment

1. Manual (export and import)

You export orders from Plentymarkets and send them (via CSV or email) to your fulfilment partner, then update shipping status and inventory manually. It’s inexpensive and requires no technical know-how, but it’s time-consuming and prone to errors. It’s manageable for just a handful of orders per day, but becomes unsustainable as soon as you grow or start selling on multiple channels.

2. Native plugin or standard integration

Some fulfilment partners or 3PLs offer a ready-to-use integration or plugin for Plentymarkets. It’s quick to set up if one exists specifically for your partner. The limitations become apparent when you combine multiple partners or warehouses, want to handle exceptions, or want to connect other systems (ERP, accounting)—in those cases, you’ll end up stacking separate integrations.

3. Your 3PL’s portal

Many fulfilment partners have their own 3PL portal where you can enter orders and view their statuses. It ’s a great way to get started, but it ties you to a single partner and doesn’t always sync your inventory back to Plentymarkets across all channels. This makes it difficult to switch partners or combine multiple warehouses.

4. An integration platform

You connect Plentymarkets and your fulfilment partner once to an integration platform, which automatically orchestrates the data flows between the two (and, if applicable, your other systems and channels). Less maintenance, a single overview, and the flexibility to add a second fulfilment partner, marketplace, or ERP later on without having to rebuild the system. This is the KoneX approach.

Method	Setup	Maintenance	Suitable for
Manual (CSV)	No technical skills	Lots of manual work	Very low volumes
Native plugin	Fast, if such a thing exists	Stacking Loose Couplings	One partner, simple setup
3PL Portal	Available immediately	Commits to one partner	Getting Started with a Single Fulfilment Partner
Integration platform	Connect once	Centralized, scales with growth	Multiple Channels/Partners & Growth

How does KoneX do it?

With the Plentymarkets – fulfilment integration from KoneX, orders are automatically sent from Plentymarkets to your fulfilment partner or 3PL (such as Active Ants/Paxon or PostNL), and shipping status, track & trace, and inventory information are automatically sent back to Plentymarkets. This ensures your inventory remains accurate across all your channels and prevents overselling. You connect each system once and can easily add a second fulfilment partner, marketplace, or ERP later — Integrate Once. Connect Everywhere.

It’s important to be honest: if you have a single fulfilment partner with a good native integration and low volume, that’s often more than enough. However, as soon as you start combining multiple channels or partners, want to centralize your inventory, or need to connect more systems, an integration platform generally becomes more reliable and less expensive to maintain.
