Linnworks Integration Services for Sellers on Many Channels
A parcel leaves the warehouse, a marketplace payout arrives days later, and somewhere in between a finance clerk is matching rows by hand. Linnworks was built to close that gap. Linnworks connects to over a hundred marketplaces, so all orders go into one queue, all SKUs have one stock level, and, depending on your rules, either a shipping company or a warehouse ships the package. Linnworks doesn’t handle your accounting or ERP system, which is where PenguinPeak Technologies comes in. We connect to your ERP, ledger, and shipping systems via Linnworks’ developer portal. We perform all synchronization using backups of your data before touching a live order.
What We Connect to Linnworks
Money and accounting
We export all the payments, refunds, market fees, and payouts to QuickBooks, Xero, and Zoho Books as channel-level summaries, not in thousands of lines. In ERPs such as NetSuite, Business Central, SAP, Odoo, Acumatica, and Sage, we also export purchase orders and goods receipts for inventory management.
Inventory and shipments
Linnworks transfers inventory quantities, locations, and shipment notifications to your warehouse management system, third-party logistics provider, or shipping application. Shipment tracking numbers return to the order so customers can track their shipment without anyone manually entering the number.
Customers and service
Order history reaches HubSpot, Salesforce, or Zoho CRM and your helpdesk, so support can see what was bought and shipped. Our digital marketing team can use the same data in email and paid campaigns.
Channels and storefronts
Shopify, WooCommerce, BigCommerce, Magento, Amazon, eBay, and others feed one order stream. If a channel isn’t on Linnworks’ list, we can build it as a channel integration that behaves like a native one, and our web developers can refresh the storefront it feeds.
Reporting and data
Once we clean product attributes, order, stock, and margin figures flow to Power BI, Looker Studio, or a data warehouse. Where listings need better copy, our AI SEO team can help.
Five Linnworks Details Every Integration Has to Respect
Open versus processed orders
New orders wait in the open list until a person or a rule processes them, then they move to the processed list. We agree with you on which stage triggers each push to your ERP.
Two kinds of identifiers
Your team uses order numbers and SKUs, while the API uses internal IDs for orders and stock items. We store the mapping between them so no lookup is ever a guess.
Stock locations
Linnworks tracks stock by location and then feeds it to each channel. A wrong location-to-channel mapping often causes overselling, so we test it with real SKUs before launch.
Rules Engine
Linnworks can handle order routing, shipping assignment, and folder sorting using its own rules engine. Integration logic stays out of that process, so changes to any rule will not break the sync.
Application Types
All API-related tasks start in the developer portal for Linnworks. System integration applications support ERP or accounting integrations, while channel and shipping integration applications act like native channels or carriers.

Where Linnworks Integrations Usually Go Wrong
Four potential failures that we protect ourselves from by design.
- Flash sale hits the rate limit. Linnworks processes too many requests and triggers a 429 error. As our connectors buffer requests, the system slows down but doesn’t break.
- A retry creates a second order. Each order carries its Linnworks reference into the ERP, so a repeated message updates the existing record.
- A channel app gets switched off. Linnworks can turn off an integration after unhandled errors. Our channel apps return the expected responses and log everything else for a human to review.
- Mismatching of ledgers and payments. On a daily basis, we reconcile channel reports with marketplace payments and note any discrepancy before the end of the month.
Why Sellers Choose PenguinPeak for Linnworks
PenguinPeak Technologies is an India-based software company. Developers, designers, and marketers sit on one team, so a Linnworks project can pick up storefront or campaign work without bringing in a new vendor.
Linnworks runs separate regional sites for the US, Australia, and New Zealand, among others, and carriers and marketplaces differ in each, so we map them region by region.
Every Linnworks build starts with a written scope and a mapping document your team signs off on. We do enough trials on copies of your data, hand over the code when we get a successful output, and support it after launch.
Frequently Asked Questions
The process involves connecting a Linnworks account to all systems that handle an order, such as your ERP system, accounting package, warehouse management system, shipping company, CRM software, and other sales channels. Linnworks pulls your orders and inventory from your marketplaces and warehouses and syncs the data back and forth. The result is a single order entry everyone can count on, minimal manual data entry, trackable transactions, and accurate inventory levels across all sales channels.
Yes, usually through the partner connector or custom development. Most often, we publish channel-level summaries rather than transactions for sales, refunds, fees, and payouts to keep the general ledger clear. We will base our decision between a pre-built connector and custom development upon your volumes, channels, and chart of accounts.
There are two cost models. Linnworks offers its own pricing based on monthly order count, with separate charges for any additional modules but no commission. The integration itself is a separate project, priced based on the number of systems to integrate, the amount of custom business logic between them, and your order volume. A ready-made connector is the least expensive option. A custom solution requires extra upfront investment, but it has no per-task integration charge. A fixed-price quote after a brief infrastructure analysis is all you need.
Linnworks integrates with ERP systems that support API- or connector-based integration, such as NetSuite, Business Central, SAP, Odoo, Acumatica, and Sage. Some offer off-the-shelf solutions, while others require custom integration. In any case, we’ll first define ownership of the stock, price list, and customers between the two systems to avoid data overlap.
Yes. The Linnworks API is a REST API that uses JSON, and most requests are POST requests. We create an application in the Linnworks developer portal, then install it in the account and exchange the application ID, secret, and installation token for an access token. Linnworks limits requests per endpoint, and when you exceed the limit, it returns a 429 error.
Linnworks claims to sync your inventory in real time via its integrated channels. However, when integrating third-party systems like an ERP, most connectors run on a schedule, so frequency depends on the interval and limits. Schedule frequency should match how fast your SKUs sell.
Linnworks does not constitute an ERP system. It helps with order management, inventory, listing, shipping, and warehouse management for your different sales channels. An ERP system offers much broader coverage than Linnworks, including finance, procurement, manufacturing, and reporting. Many users use Linnworks and an ERP together, with Linnworks as the front-end layer and the ERP as the back-end system of record.
Yes. Linnworks supports channel and shipping integration application types that behave like native ones, so you can still connect a regional marketplace or local carrier missing from its list. We build the application, host its endpoints, and handle the error responses Linnworks expects, since unhandled errors can automatically switch off a customer’s integration.
