Managing orders across multiple eCommerce channels used to mean juggling spreadsheets, manual CSV exports and the constant risk of human error. DespatchLab — the award-winning logistics platform built by Diamond Logistics — changes all of that. And as a Reilly's client, you get full access.
What is DespatchLab?
DespatchLab is described by Diamond Logistics as the UK's only platform that unites fulfilment, multi-carrier shipping and same-day delivery in a single system. It's the operational backbone of Reilly's Express Delivery, giving our clients enterprise-level logistics technology without the enterprise-level complexity.
Which platforms does DespatchLab integrate with?
DespatchLab integrates with over 40 eCommerce channels via API, including:
- Shopify — orders sync automatically the moment they're placed
- Amazon — FBM orders pulled directly, tracking fed back in real time
- eBay — managed returns and despatch confirmations handled automatically
- WooCommerce — bidirectional sync with inventory updates pushed back to your store
- TikTok Shop — fast-growing channel with full API support
- Magento, Linnworks, DEAR and 35+ more
What does the DespatchLab dashboard show?
Logging into DespatchLab gives you a live view of your entire logistics operation:
- Fulfilment orders — status, movements, picking progress
- Overnight carrier shipments — manifested, in transit, out for delivery, delivered
- Same-day bookings — live status updates
- Stock levels — real-time inventory across all SKUs
- Returns — received, inspected, restocked or disposed
How does multi-carrier selection work?
Rather than being tied to a single carrier, DespatchLab selects the optimal carrier for each shipment — comparing DHL, DPD, Royal Mail and Yodel on speed, price and destination coverage. You get the best route every time, with a single consolidated invoice regardless of how many carriers are used.

Why platform integration matters for eCommerce fulfilment
Manual order processing is the single biggest bottleneck in growing eCommerce operations. If your 3PL requires you to export orders from Shopify, format them into a CSV and email them across every morning, you're already running a process that breaks the moment volumes increase. You'll miss orders, ship late and damage your marketplace metrics.
Direct platform integration eliminates this entirely. When DespatchLab connects to your Shopify store, Amazon Seller Central or TikTok Shop via API, orders flow automatically from the moment they're placed. No exports, no manual steps, no human error in the middle.
How DespatchLab integrates with each platform
Shopify: DespatchLab connects to Shopify via the official Shopify API. Orders are pulled in real time from your Shopify store, including all product variants, customer addresses and order notes. Once despatched, tracking information is automatically pushed back to Shopify and your customer receives their shipping notification immediately.
Amazon: Amazon Seller Central integration pulls orders from both Fulfilled by Merchant (FBM) and Multi-Channel Fulfilment (MCF) programmes. DespatchLab handles the fulfilment SLA tracking that Amazon requires, uploading tracking information within Amazon's required window to protect your seller metrics.
TikTok Shop: As an official TikTok Shop fulfilment partner through Diamond Logistics, Reilly's DespatchLab integration uploads tracking back to TikTok Shop automatically — protecting the despatch rate and on-time delivery metrics that determine your shop's visibility on the platform.
eBay: eBay orders sync directly into DespatchLab with all buyer details and postage requirements. Tracking is uploaded back to eBay automatically, which is essential for maintaining Top Rated Seller status.
WooCommerce: WooCommerce integration works via the WooCommerce REST API. Orders from your WordPress store are pulled into DespatchLab in real time with stock levels updated across both systems after each despatch.
Linnworks: For brands already using Linnworks as their order management system, DespatchLab integrates directly — pulling orders from Linnworks' unified order pool and pushing back tracking for all channels simultaneously.
Stock management across multiple channels
The real power of DespatchLab isn't just order routing — it's unified stock management. When you're selling on Shopify, Amazon and TikTok Shop from the same warehouse, your stock count needs to be accurate across all three platforms in real time. If you oversell because TikTok Shop didn't know your Amazon just bought the last 50 units, you've got a customer service problem on three channels simultaneously.
DespatchLab maintains a single central stock count. Every time an order is picked and despatched, stock is deducted from the master count and all connected platforms are updated immediately. This means your live Shopify inventory, your Amazon available quantity and your TikTok Shop stock level all reflect the same accurate number at all times.
For brands managing seasonal peaks, promotions or TikTok viral spikes, this is the difference between smooth operation and total chaos.
