01 · What you get

What an Unipart Logistics integration gives you.

Orders move cleanly through fulfillment

Confirmed online and call-centre orders reach the warehouse within SLA, with no re-keying or manual interventions. Pickers and packers have reliable, complete information.

Customers see timely despatch notifications

Tracking and carrier details reach the storefront and customer email immediately after Unipart confirms despatch, improving trust and reducing customer service load.

Stock stays accurate across channels

Warehouse picks and returns are reflected in real-time inventory, so online and branch stock displays stay in sync and oversells are prevented.

Finance and operations reconcile

Despatch confirmations and stock movements feed ERP without manual entry, so invoicing, COGS and inventory ledgers stay current and audit-ready.

Exceptions are visible and actioned

Unfulfillable orders, address faults, returns complications and carrier failures surface to the right team immediately so resolution is fast and customer impact is minimised.

02 · When it's worth it

Where an Unipart Logistics integration earns its place.

If two or more of these are true, the integration usually pays for itself quickly.

Route orders from commerce and call centre into Unipart's warehouse management system
Pull despatch confirmations and tracking numbers back to the storefront and customer email
Sync stock movements and returns between warehouse, ERP and inventory systems
Handle split shipments, multi-location picks and exceptions when orders cannot be fulfilled
Reconcile warehouse activity against commerce order records and ERP ledgers
03 · The limits

Where off-the-shelf connectors fall short.

Vendor connectors are fine for simple cases. Here's where the real ones need more.

Split shipments and multi-location orders

Unipart's standard API may not fully reflect complex routing rules where one order splits across multiple warehouses or locations. iWeb defines how split orders are tracked and reported back to commerce so the customer sees coherent despatch communication.

Returns and RMA workflows

Returns processing typically requires manual intervention or custom logic to map refund decisions, restocking flags and disposal routes. iWeb clarifies who owns each decision and ensures returns loop back to commerce without losing tracking or refund linkage.

Peak demand buffering

During high-volume periods, Unipart may apply holding queues or batching that delays order acceptance into the WMS. iWeb defines acceptable lag windows and fallback behaviour if orders queue beyond agreed SLAs.

Real-time stock visibility

Stock feeds from Unipart may be batch-based or infrequent, introducing lag between actual picks and commerce availability display. iWeb designs buffering logic and clearly communicates when stock is reserved but not yet despatch-confirmed.

Exception handling and customer communication

When orders cannot be picked (out-of-stock, damaged goods, address faults), Unipart flags them but the decision to cancel, amend or retry often falls outside the system. iWeb ensures exceptions reach the right team and customer promptly.

03b · Honest limits

When Unipart Logistics may not be the simplest fit.

A short, honest list. Not a warning; just where a different shape of system usually costs less to run.

A single carrier and a warehouse the current process handles well
No operations lead willing to own rule maintenance
Expecting the storefront to own the fulfilment truth
Order volumes far below the vendor threshold
04 · The real work

Warehouse systems define whether orders reach customers on time, but most integrations treat despatch as a side effect rather than a critical path with owned exception handling and monitoring.

05 · Where it sits

Where this integration sits in your estate.

Unipart Logistics holds the commercial record. The iWeb integration layer manages the rules, mappings, monitoring and exceptions. The commerce platform presents the customer-facing experience. The estate map helps agree ownership before anything is built.

Connect across your stack. Unipart Logistics plugs into the systems that run your trading operation, whichever ecommerce platform sits at the front.

07 · Data flows

The data flows we wire.

Each flow has a direction and an owner. We agree both before a line of code is written.

Into COMMERCE & ERP
From COMMERCE & OTHER SYSTEMS
BOTH WAYS
Orders into warehouse: Confirmed orders from checkout move to Unipart's WMS with customer, item, address and special instructions
The integration confirms order receipt and flags any validation failures so unfulfillable orders are caught before picking starts.
Despatch and tracking: When orders ship, Unipart sends back despatch confirmations with actual items picked, carton/pallet numbers, carrier and tracking references
iWeb ensures this reaches the storefront in time for customer notification and email.
Stock movements and returns: Stock levels sync between warehouse, ERP and commerce so availability is current
Returns from customers are logged in Unipart, reflected back to ERP and available for restocking or disposal decisions.
Fulfillment events for finance: Despatch confirmations and goods-receipt movements feed ERP so invoicing, COGS and stock valuation stay in step with actual warehouse activity.
Inventory adjustments: Corrections, shrinkage, damage and stock-take adjustments initiated in ERP or branch systems flow to Unipart so the warehouse record stays aligned with the financial ledger.
08 · How we build it

How iWeb configures the integration around your business.

Same method on every integration. The decisions come before the code.

  1. 01
    Design order and despatch flows

    iWeb maps which orders go to Unipart, which special instructions are included, how split shipments are tracked, and how despatch confirmations flow back to commerce and ERP for customer notification and accounting.

  2. 02
    Build secure, resilient connections

    iWeb implements authenticated API calls or EDI connections to Unipart with retry logic, dead-letter handling and fallback routes so temporary outages do not lose orders or leave dispatch confirmations stranded.

  3. 03
    Define exception handling and escalation

    iWeb clarifies what happens when orders cannot be picked, addresses fail validation, or carriers are unavailable. Escalation paths and customer communication rules are set before problems occur.

  4. 04
    Monitor and observe live fulfilment

    iWeb sets up dashboards and alerts so operations can see order lag, unshipped backlogs, returns queues and stock drift in real time. Problems are caught before customers complain.

09 · Ownership

Who owns what.

The single most important table in any integration. One system owns each field; everything else reads it.

10 · Experienced integrator

Built Unipart integrations before

iWeb understands how Unipart fits into multi-channel and omnichannel commerce estates. We have designed the data flows, exception handling and monitoring for warehouse systems that sit between storefront, ERP and customer service.

Unipart integrations require careful order-to-despatch flow design and peak-demand buffering; iWeb ensures orders do not stall or get lost in queues.
Despatch confirmation timing is critical for customer trust and ERP invoicing accuracy; iWeb monitors and alerts on tracking delays.
Returns workflows must be crystal-clear; iWeb defines who decides restocking, refund trigger points and exception escalation so returns do not fall between systems.
Stock synchronisation between warehouse and ERP prevents oversells and inventory drift; iWeb implements reconciliation checks and alerts on unexplained movements.
iWeb ensures Unipart sits cleanly alongside OMS, ERP and customer service so exception handling is owned and visible rather than silently failing.

11 · Before launch

What we test before launch.

Every one of these is rehearsed before a customer ever sees the integration.

Confirm a test order routes to Unipart, appears in their WMS within SLA, and is available for picking without delay or validation error.
Verify despatch confirmations (items, tracking, carrier) flow back to the commerce order within 5 minutes of Unipart dispatch confirmation.
Test an unfulfillable scenario (out-of-stock, address fault) and confirm the exception reaches the right team and customer without silent failure.
Reconcile stock balances between ERP and Unipart after a full picking and return cycle to ensure no drift or missing adjustments.
Simulate Unipart API downtime and confirm orders queue locally, retry successfully when service restores, and no orders are lost.
Check that split shipments and multi-parcel orders generate separate tracking notifications so customers see all parcels tracked independently.
Run a returns scenario end-to-end: return arrives, logged in Unipart, refund triggered in ERP, customer notified, and stock available for resale within agreed timeline.
12 · Failure points

Common risks and where they bite.

We name these on day one. A risk written down is a risk you can plan around.

Orders stuck in queue or silently rejected

If order validation fails or Unipart's inbound queue fills during peak demand, orders may be held without alerting commerce. Customers do not get tracking, and finance does not invoice. iWeb ensures acceptance is confirmed or rejection is escalated immediately.

Tracking and despatch confirmation gaps

If Unipart despatch feeds lag or fail, customers wait for tracking that never arrives, support teams chase shipments, and ERP remains unaware orders have shipped. iWeb monitors despatch latency and escalates missing confirmations.

Stock movements not reflecting in ERP or commerce

If stock adjustments from the warehouse do not sync back, ERP ledgers diverge from actual availability, leading to oversells, phantom inventory or invoicing mismatches. iWeb ensures reconciliation is monitored and drift is caught within SLA.

Returns lost or misrouted

Returns from customers may arrive at the warehouse but not be logged in Unipart or communicated back to commerce. Refunds stall, stock does not reappear, and operations lose visibility. iWeb defines returns inbound process and tracks each return from customer through restocking decision.

Peak demand causing service degradation

During high-volume periods, Unipart may batch orders or apply holding periods, delaying picking and despatch. If SLAs are not defined upfront, customer expectations fail and finance gets credit notes. iWeb clarifies peak capacity and fallback routing.

Unowned exception queues

Address validation failures, out-of-stock picks and carrier errors accumulate in exception queues without a named owner or clear resolution path. Orders remain unfulfilled and customers are not updated. iWeb assigns ownership and escalation rules before go-live.

14 · Questions

Common questions about Unipart Logistics integrations.

How do orders flow from our storefront to Unipart?

Confirmed orders are sent via API or EDI feed to Unipart's WMS with customer, item, quantity, address and special instructions. iWeb defines which order statuses trigger transmission and ensures all required fields are validated before dispatch to the warehouse.

What happens if Unipart cannot pick or fulfil an order?

Unipart flags the order as unfulfillable (out-of-stock, address fault, damaged goods). iWeb routes the exception to your operations or customer service team immediately and defines who decides whether to cancel, amend or retry the order. Customer notification is sent according to your policy.

How does dispatch confirmation get back to our customers?

When Unipart packs and ships an order, the despatch data (items, carrier, tracking) flows back via API. iWeb maps this to your order record and triggers customer email notifications so they receive tracking immediately.

How do we handle split shipments or multi-location orders?

If an order is split across multiple Unipart locations or ships in multiple parcels, iWeb aggregates the despatch events and sends a consolidated or multi-parcel notification to the customer. Each parcel has its own tracking reference and status.

How do stock levels stay accurate between Unipart and our ERP?

iWeb syncs warehouse picks, returns, shrinkage and stock-take adjustments from Unipart back to ERP at defined intervals. Stock is reserved on order confirmation and committed when despatch is confirmed, preventing oversells.

What happens when a customer returns an item?

Returned items arrive at Unipart, are logged in the WMS, and iWeb ensures the return is linked to the original order and communicated back to your commerce platform and ERP. Refund decisions (restock, scrap, resale) are clarified upfront so returns do not stall.

How do we monitor orders that are stuck or not despatch-confirmed?

iWeb builds dashboards showing order-to-despatch lag, unshipped backlog by age, and exception queues. Alerts trigger if orders exceed SLA without confirmation, so the team can investigate Unipart hold-ups or customer service issues.

What if Unipart's system goes down or despatch feeds are delayed?

iWeb implements retry logic and dead-letter queues so failed orders are not lost. If despatch feeds lag beyond SLA, alerts notify operations. Temporary outages trigger a fallback: orders may be queued locally until Unipart recovers, or rerouted to another warehouse if available.

How do address validation failures or carrier errors get handled?

Unipart flags addresses that fail delivery validation and carrier rejections (e.g., too heavy, restricted postcode). iWeb routes these exceptions to a named team for correction; the customer is contacted with new delivery options or timeline. No order is abandoned silently.

How does finance know when orders are really shipped so invoicing is accurate?

Despatch confirmations from Unipart feed ERP immediately after Unipart confirms the shipment. iWeb ensures the invoice is triggered at this point, not at order placement, so revenue recognition aligns with actual fulfillment.

Can we route different order types to different Unipart locations?

Yes. iWeb can define routing rules based on product type, location, order size or customer segment. Orders route to the appropriate Unipart warehouse automatically, with exception handling if the preferred location cannot fulfill.

What level of real-time visibility does the integration provide?

iWeb pulls despatch confirmations immediately after warehouse confirmation, so tracking is available within minutes of packing. Stock movements may be batch-fed at defined intervals (e.g., hourly). Backlogs and exceptions are monitored in real time with alerting.

How do we handle peak demand periods when Unipart's volume capacity is stretched?

iWeb clarifies Unipart's peak SLAs upfront (e.g., order acceptance lag, pick timelines). During peak, orders queue locally if needed but are logged and communicated to the customer. iWeb monitors SLA breach and escalates if delays risk missing promised delivery windows.

Who owns the decision to cancel or hold an order after it has reached the warehouse?

This is defined upfront by iWeb. Typically, Unipart holds the order if customer-initiated cancellation arrives after picking has begun, and customer service confirms the final decision. iWeb ensures communication flows between warehouse, customer service and ERP so decisions are logged.
