Connecting Pricemaster to Linnworks

How It Works

Connect Linnworks once and Pricemaster reprices every channel

Linnworks already sits at the centre of your operation and feeds all of your sales channels — Amazon, eBay, your Shopify, Magento or BigCommerce store, your own website and any marketplaces. Because Pricemaster connects straight to Linnworks through the official Linnworks API, one connection links Pricemaster to your entire multichannel catalogue. There is nothing to set up per channel.

The flow is a closed loop: Pricemaster reads your catalogue, watches the market, calculates new prices inside your margin rules, and writes them back to each item's retail price in Linnworks. Linnworks then distributes that price out to every channel the item is published on — exactly as it does today.

Reprice once, everywhere: you don't integrate each marketplace separately. Pricemaster updates the price in Linnworks and Linnworks handles the channel distribution you already rely on.

What Syncs

What Pricemaster reads, and what it writes back

Imported from Linnworks

Pricemaster pulls your stock items page by page and captures, for each one:

SKU (Linnworks item number)
Title & description
Barcode / GTIN — used for accurate competitor matching
Category
Current retail price
Cost / purchase price — powers margin maths
Tax rate (VAT handled correctly)
Stock quantity
Main product image
Orders, open and despatched, for sales and profit reporting

Written back to Linnworks

The only thing Pricemaster changes is the price:

The retail price on the base stock item, and only once price updates have been switched on for your account. Until then Pricemaster calculates prices and changes nothing in Linnworks.
Every change is logged with the rule that caused it, the old and new price, and the resulting margin.
Before each update Pricemaster records the price Linnworks held, so any update can be rolled back to exactly what was there.

Pricemaster does not touch your orders, stock levels, listings or channel configuration.

VAT & variations handled for you: prices are normalised to a consistent ex-VAT basis internally for correct margin calculations, then written back in the format your account expects. Placeholder "variation parent" records are skipped, so it's your real, sellable items that get tracked and priced.

Before You Start

What you need (and what you don't)

Connecting is a standard Linnworks app approval — the same flow you use for any Linnworks add-on. You'll need:

An active Linnworks account with your catalogue and channels already set up.
A Pricemaster account. Create one at pricemaster.ai/signup.
To be signed in to Linnworks as the Account Holder, the person the Linnworks subscription is under. Linnworks only lets the Account Holder install applications.

You do not need:

Any CSV exports or imports — your catalogue imports itself.
Developer work, or API keys to generate and paste by hand.
Per-channel integration — Linnworks already handles channel distribution.

Connecting Your Account

Authorise Pricemaster on Linnworks

1

Pick Linnworks on the onboarding screen

From the onboarding "What platform are you using?" screen, choose Linnworks.

2

Enter a site name

Give the site a name (for example Acme Linnworks) and, optionally, your shop URL. Then click Authorise Pricemaster on Linnworks.

3

Approve Pricemaster in Linnworks

A new tab opens on Linnworks. Click Install application to approve Pricemaster. You can leave the Pricemaster tab open — it's waiting for Linnworks to confirm.

4

The connection is detected automatically

Linnworks confirms the approval back to Pricemaster server-to-server, so there is no token to copy or paste. The onboarding page detects it, verifies the account (it reads back your company name so you can confirm you've connected the right one), and takes you straight to your products.

Installed Pricemaster from the Linnworks Application Store first? That works too. Create your Pricemaster account, choose Linnworks on the onboarding screen and either click Authorise Pricemaster on Linnworks or expand "Already have an Installation Token?" and paste the token Linnworks showed you. Our team is told about every install made from inside Linnworks, so if you would rather we finished the connection for you, email [email protected].

After You Connect

What happens next

Pricemaster kicks off the first catalogue import in the background and walks you through the rest of onboarding:

1

Products import

Your Linnworks stock items are pulled in with their titles, barcodes, cost, tax, stock and images. You can watch progress from the products area.

2

Match and select competitors

Each product is matched to competitor listings, primarily by GTIN. You then enable the competitors that matter for your market.

3

Set your rules and go live

Build your pricing rules — follow-the-market, undercut, flat markup, flash — always inside your minimum-margin and cash-floor guardrails. Simulate any rule to see the price, margin and market position of every product before anything is sent. Going live is a deliberate step: price updates are switched on for your account with the Pricemaster team once you are happy with what the simulation shows. From then on you can send prices to Linnworks on demand, and turn on the daily automatic update yourself under Settings → Price pushing.

When cost prices change in Linnworks, repricing recalculates on the new cost basis so your margins hold. Orders are imported from Linnworks as well, so sales and profit reporting cover every channel Linnworks handles.

Security & Control

You stay in control of the connection

Access is via a per-account installation token that Linnworks issues when you approve the app.
You can remove access at any time by uninstalling Pricemaster in Linnworks under Settings → Applications — no need to contact us first. Pricemaster stops reading and writing the moment you do.
Pricemaster requests only what it needs: read your catalogue, and update retail prices. It does not modify orders or channel settings.
Your Linnworks data stays the single source of truth; Pricemaster reads from it and writes prices back.

FAQs

Common questions

Which sales channels does this cover? All of them, indirectly. Pricemaster updates the price in Linnworks and Linnworks distributes it to whatever channels each item is published on — Amazon, eBay, Shopify, Magento, your website, marketplaces. You don't integrate each channel separately.
Will it change anything other than prices? No. It reads your catalogue and updates the retail price of items. Orders, stock levels, listings and channel configuration are left untouched.
How often do prices update? Competitor prices are refreshed throughout the day. Prices are sent to Linnworks when you send them, or once a day if you have turned the automatic update on. Nothing is sent automatically unless you have switched it on.
Can I undo a price update? Yes. Every update records the price Linnworks held beforehand, and Settings → Price pushing lists recent updates with a roll back button for each.
Who can install the app? The Linnworks Account Holder. Linnworks refuses the install for any other user.
Won't automated pricing undercut my margins? No. Every automated price passes through your minimum-margin percentage and minimum cash-margin floors before it is sent. If a rule would breach a floor, the floor wins.
Do I need CSVs or a developer? No. You authorise the Pricemaster app in Linnworks and the catalogue imports itself — nothing to export, format or upload.
I already have an installation token — can I skip the authorise step? Yes. On the connect screen, expand "Already have an installation token?" and paste the token from Linnworks under Settings → Applications → Pricemaster.
