Connected To The Stack You Already Run

Orders arrive from every channel you sell on, stock syncs back, and dispatch confirmations land where your customers look for them. No exports, no re-keying, no reconciliation by spreadsheet.

17 named connections listed below — count them. Anything not here connects over the API.

Connection methods

What “integrated” actually means in each case

A native connection and a spreadsheet on a timer are both described as integrations. They behave completely differently when a platform changes something, so each entry below says which one it is.

Platform app

Connected through the platform's own app or connector, authorised by you from inside your admin.

REST API

Your system calls our documented REST API, or we call yours. Used by headless builds and in-house platforms.

Native integration

A direct connection we build and maintain. Orders and stock move without a third party in between, and we own the fix when the platform changes.

EDI

Structured trading documents exchanged to a retailer's specification, for supplying into a distribution centre.

Scheduled file transfer

Scheduled CSV or flat-file exchange over SFTP, for systems with no API worth using.

Webhook events

Events pushed the moment they happen — order created, stock changed, parcel dispatched — instead of polling on a timer.

01

eCommerce platforms

Your own storefront — where the order originates and the stock figure has to stay honest.

Shopify & Shopify Plus

Orders pull continuously, fulfilments and tracking write back, stock syncs per location.

Platform app

WooCommerce

Connected by plugin with order status and tracking written back to the WordPress store.

Platform app

Magento / Adobe Commerce

Connected over the REST API, including multi-store and multi-currency setups.

REST API

BigCommerce

Native order pull with dispatch confirmation and inventory sync.

Platform app

02

Marketplaces

Merchant-fulfilled orders picked and dispatched against Amazon's handling times.

FNSKU labelling, polybagging, bundling and carton compliance before shipment plans go in.

04

Technology & data

How the connection is maintained, monitored and reported on once it is live.

REST API

Documented endpoints for orders, inventory, dispatches and returns. Credentials issued at onboarding.

REST API

Webhook events

Multichannel managers

Linnworks, ChannelAdvisor and similar tools sit in front of us where you already run one.

Scheduled file transfer

Reporting exports

Stock, movement and dispatch reporting exported to your finance or BI stack.

Data flow

How stock stays right across every channel

Overselling is the failure mode that costs you a marketplace account, so it is worth being specific about how it is prevented rather than promising that it will not happen.

01

One stock pool, not one per channel

Every channel reads the same available-to-sell figure. Splitting stock between channels is what creates the situation where one sells out while another is still advertising it.

02

Allocated at order, not at pick

Stock is reserved the moment an order lands, so it stops being available to every other channel immediately rather than an hour later when a picker reaches the shelf.

03

Continuous sync, not a nightly batch

Changes push within minutes on platforms that support webhooks, and on a short polling cycle where they do not. The exact interval per platform is confirmed at onboarding.

04

Buffer stock where a channel is punitive

Marketplaces that penalise cancellations can be given a holdback figure you set, so a race between two channels never becomes a defect on your account.

05

Cycle counts close the drift

Rolling counts by location correct the gap between the system and the shelf continuously, rather than in one annual reconciliation that invalidates a year of reporting.

06

Failures raise an alert on our side

A dropped connection triggers an alert to us, not a silent gap you discover from a customer email. Where a platform has changed its API, we handle the update.

Client portal

What you see once you are live

Orders, stock, dispatches, returns and low-stock alerts in one view, with the reporting exports your finance team will ask for.

  • Live order status from receipt through to carrier scan
  • Stock on hand by SKU and by location, with allocated versus available
  • Dispatch history with tracking references against each order
  • Returns received, graded and the outcome recorded
  • Low-stock alerts against reorder points you set
  • Exportable stock, movement and dispatch reporting

Connecting your systems to ours

Shopify and Shopify Plus, WooCommerce, Magento, BigCommerce, Squarespace, Wix, Amazon, eBay, Etsy and TikTok Shop natively or through a multichannel manager. Anything else can usually be connected over our REST API, by webhook, or by scheduled file transfer.
