# Exception Rate, Interlink Express

> Exception Rate for Interlink Express stores. Tracked live in Vortex IQ Nerve Centre. How to read it, why it matters, and how to act on it.

**Metrics type:** [Key Metrics](/nerve-centre/overview#metrics-types-explained)  •  **Category:** [Shipping & Courier](/nerve-centre/connectors#connectors-by-type)

## At a glance

> Share of Interlink Express consignments that hit any non-success scan event in the period: failed first attempt, customer-not-home, address issue, refused, damage, "out for delivery, returned to depot". Exception is broader than "late" because some exceptions ultimately deliver on-time after a re-attempt, and the DPD-group predicted-window infrastructure makes some exceptions invisible to the customer (driver re-routes via the predicted-window engine).

|                                     |                                                                                                                                                                                                                                                                                                                                                                         |
| ----------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **What it counts**                  | `COUNT(DISTINCT shipments WHERE any_event IN ('FAILED_ATTEMPT','REFUSED','RTS','DAMAGED','UNDELIVERABLE','REDIRECT')) / COUNT(shipments)` over rolling 30 days. A consignment with multiple exception events counts once.                                                                                                                                               |
| **What counts as "exception"**      | Any non-success scan event in Interlink's tracking webhook. Carded "Sorry we missed you" is an exception. Customer-not-home is an exception. Refused-at-door is an exception. The DPD-group predicted-window auto-redirect (where a driver re-routes around a not-home recipient via real-time customer SMS) reduces the headline; this is a network-feature advantage. |
| **Customer-fault vs carrier-fault** | Pooled. Roughly 60 to 70% of premium-tier exceptions are customer-fault (recipient absent, address wrong, refused); 20 to 30% are carrier-fault (driver mis-route, depot delay); 5 to 10% are external (weather, force-majeure). Pair with `int_failed_delivery_count` for the carrier-fault-only view.                                                                 |
| **Service level scope**             | All services pooled (Pre10:30, Pre12, Next-Day, 2-Day, Saturday).                                                                                                                                                                                                                                                                                                       |
| **Money-back-on-late interaction**  | Customer-fault exceptions do *not* qualify for service-failure refund. Carrier-fault exceptions on time-definite tiers usually do. The exception count and the refund-eligible-late-count diverge predictably; pair with `int_open_claims`.                                                                                                                             |
| **Predicted-window advantage**      | Interlink (DPD-group) inherits the "1-hour predicted window" customer SMS / app comms. Customers who receive the SMS and rebook delivery before the carded attempt happens reduce the exception rate by 0.5 to 1.5 percentage points vs comparable non-predicted-window carriers.                                                                                       |
| **B2B vs B2C**                      | Pooled. B2B addresses (corporate reception with named-recipient signature) generate fewer recipient-not-home exceptions. A merchant shifting B2C-heavy will see exception rate creep upward.                                                                                                                                                                            |
| **Time window**                     | `30D vsP`                                                                                                                                                                                                                                                                                                                                                               |
| **Alert trigger**                   | `>3%` critical, `>1%` good. Interlink premium tier typically runs 1.0 to 2.5% (slightly below Parcelforce due to predicted-window advantage).                                                                                                                                                                                                                           |
| **Roles**                           | owner, operations                                                                                                                                                                                                                                                                                                                                                       |

## Calculation

Calculated automatically from your Interlink Express data. See the At a glance summary above for what the metric tracks and the worked example below for a typical reading.

## Worked example

A UK premium-fashion merchant: £210 average-order-value womenswear, mostly Next-Day DTC consumers with a small B2B reseller cohort on Pre12. Brand sets a high bar on customer experience; exception rate is a tracked KPI in monthly stakeholder review. Reading taken at 09:00 GMT on 02 Apr 26 for the trailing 30 days (02 Mar 26 to 01 Apr 26).

| Exception reason                   | Consignments | % of exceptions | % of total volume |
| ---------------------------------- | ------------ | --------------- | ----------------- |
| Recipient absent (no safe place)   | 45           | 38%             | 0.9%              |
| Address details required           | 22           | 19%             | 0.4%              |
| Refused at door                    | 18           | 15%             | 0.4%              |
| Damaged in transit                 | 12           | 10%             | 0.2%              |
| Driver mis-route / depot delay     | 14           | 12%             | 0.3%              |
| Auto-redirect via predicted-window | 7            | 6%              | 0.1%              |
| **Total exceptions**               | **118**      | 100%            | **2.4%**          |

Total volume: 4,950 consignments. The card reads **2.4%**, comfortably under the 3% alert. Five things to notice:

1. **Recipient-absent at 38% is below the carrier average** (\~50 to 60% is typical). The DPD-group predicted-window SMS reaches customers in time to reschedule, reducing carded-redelivery exceptions. The merchant benefits from the network feature without explicit configuration.
2. **Refused-at-door at 15% is high for fashion.** Customers are receiving and refusing the parcel. Likely causes: (a) sizing-buyer-regret, (b) checkout error / duplicate order, (c) packaging arrived visibly damaged. Cross-reference Shopify cancellation patterns; refused-at-door spike often follows a customer-initiated cancellation that did not reach the warehouse in time.
3. **Damaged-in-transit 0.2% of total volume** is healthy for fashion (under 0.5% benchmark). Premium-fashion packaging tends to be over-engineered (rigid boxes, branded inner-wrap) which protects contents.
4. **Refund-eligible exceptions are the 14 driver-mis-routes (12%) plus a portion of the damaged-in-transit (case-by-case).** That is \~£140 of carriage refund opportunity (14 × £10 Next-Day) plus \~£300 of damage-claim recovery. File within the 14-day window.
5. **2.4% exception rate against a 1.0 to 2.5% premium-tier benchmark is in spec.** No urgent action; track the refused-at-door cohort because it correlates with downstream refund rate (`shopify.refund_rate`). A 1-point refused-at-door rise typically shows up as a 0.3 point Shopify refund-rate rise at 5 to 10 day lag.

## Sibling cards merchants should reference together

Exception rate is the broad operational-noise gauge. To triage:

## Reconciling against the vendor's own dashboard

**Where to look in Interlink Express's own dashboard:**

[Interlink Express MyDPD Business](https://www.interlinkexpress.com/) → **Reports → Exceptions Summary**. Filter by *All services / Last 30 days*. Per-consignment audit at *Track and Trace → Filter "Issues"*.

**Why our number may legitimately differ from Interlink's portal:**

## Known limitations / merchant FAQs

**Why is Interlink's exception rate typically lower than Parcelforce's or APC's?**
The DPD-group predicted-window infrastructure: customers receive a 1-hour-window SMS or app notification on the morning of delivery, with the option to rebook before the driver arrives. This shifts a portion of would-be carded-redelivery exceptions out of the count entirely. Parcelforce and APC have less mature predicted-window features and therefore see higher recipient-absent exception rates.

**The auto-redirect-via-predicted-window count is rising; is that good or bad?**
Good in absolute terms (the customer rerouted before failing), modestly bad in relative terms (it indicates the customer was not at the original address). Operationally it is a net win: the consignment delivers, the customer is happy, and the merchant is not paying for a redelivery. Track it as a leading indicator of customer-mobility patterns.

**Refused-at-door is climbing on our fashion brand; is it a sizing issue?**
Often. Fashion refused-at-door correlates with sizing-buyer-regret (customer realises in transit they ordered the wrong size and refuses to accept). Cross-reference Shopify "cancelled in transit" patterns; if there is a pre-shipped cancellation cohort that did not reach the warehouse in time to halt dispatch, this is the root cause. Solution: improve mid-funnel size-guidance and reduce checkout-to-cancel velocity.

**Damaged-in-transit looks lower on Interlink than other carriers; why?**
DPD-group sortation centres are heavily automated, with relatively gentle parcel handling vs hand-sorted networks. Damaged-in-transit on Interlink typically runs 0.1 to 0.3% of total volume, lower than APC (0.3 to 0.5%) and Parcelforce (0.2 to 0.4%). For glass/fragile cohorts, Interlink is often the carrier of choice.

**Customer-fault exceptions: should we filter them out of the headline?**
Today no; the card includes all exceptions because all affect customer experience and CS-team load. If you need the carrier-fault-only view for refund-recovery sizing, use `int_failed_delivery_count` plus `int_open_claims`.

**During Q4 peak, exception rate spikes; is this signal or noise?**
Both. Q4 saturation lifts UK premium-carrier exception rate by 1 to 2 percentage points. Interlink's automation footprint holds up slightly better than smaller competitors (sortation centres scale up); expect a 1 to 1.5 point Q4 dip rather than the 2 to 3 point dip on hand-sorted networks. Read Q4 numbers in seasonal context.

**B2B reseller exceptions are near-zero; why?**
Predictable corporate addresses, named-recipient sign-off, business-hours-only delivery. B2B-cohort exceptions on Interlink Pre10:30 typically run under 0.5% (a fifth of consumer DTC). The selection bias is structural; B2B-cohort exception rate is not a comparable benchmark.

**The carded-redelivery cohort dropped after the merchant connected the predicted-window SMS; how does that work?**
Interlink's tracking webhook publishes a 1-hour predicted window on morning-of-delivery. If the merchant or merchant's commerce platform forwards that to the customer (Shopify Shipping Notifications, BC Order Confirmations, or via a Klaviyo flow), the customer can act on it. Carded-redelivery falls 30 to 50% on accounts that wire the SMS / email through. Pair this card with the rollout-week of any such integration to see the lift.

**How do exception clusters in specific postcodes show up?**
Not in this headline rate. Use `int_route_otd` (geographic OTD split) and `int_shipments_by_destination` (volume by postcode) for the geographic view. Some postcodes structurally generate higher exception rates (apartment blocks, rural addresses, restricted-access B2B sites); they aggregate into the headline.

**Compared to Parcelforce, when should we choose Interlink for a cohort?**
Interlink wins on consumer-DTC-customer-experience (predicted-window SMS, predicted 1-hour delivery slot communication) and on damage-sensitive cohorts. Parcelforce wins on rural coverage and on Saturday-uplift availability. Most multi-carrier merchants run Interlink for urban DTC and Parcelforce for rural and weekend.
