How to Reduce Failed Deliveries

Reduce failed deliveries by improving the order before dispatch, making promises from real capacity and giving drivers a safe, consistent exception process.

Step 1: establish a reliable baseline

Review at least several representative weeks and separate failures by cause. Count attempts that were recovered as well as orders that ended in a refund. A process can be expensive even when the customer eventually receives the food.

Step 2: improve address capture

• Require postcode and a complete delivery address.
• Provide separate fields for flat, building, access code and delivery note where useful.
• Validate the address, but let staff review new developments and unusual properties.
• Show the customer the final formatted address before payment.
• Do not overwrite a customer correction silently with an automated match.

Step 3: verify contact details without creating friction

Use format checks and order confirmation to catch obvious mistakes. Explain why a mobile number is needed for delivery. Do not use a service contact number for marketing unless the separate marketing rules are met.

Step 4: make the promise from the whole system

The delivery estimate should include kitchen capacity, packing, driver assignment, journey and handover. A postcode may be inside the zone but still unavailable when capacity is full or severe weather makes the route unsafe.

Step 5: send useful updates

• Confirm that the order is accepted, not merely that payment was attempted.
• Use “on the way” only after the driver has the complete order.
• Provide a secure contact or tracking route.
• Notify the customer when the promise changes materially.

Step 6: define the driver protocol

1. Stop in a safe place before using the phone.
2. Confirm the property and delivery note.
3. Use the approved contact sequence.
4. Wait only for the defined safe period.
5. Report the cause to the shift lead.
6. Follow the return, hold or disposal instruction.

Step 7: test boundary and failure cases

Place test orders for flats, gated properties, new postcodes, multiple bags, wrong phone numbers, unavailable drivers and payment success without order receipt. Test the business process, not only the checkout screen.

Step 8: verify improvement

Track failure rate by cause, but also measure contact attempts, redelivery cost, refunded value, driver waiting and customer complaints. Stop a change if it reduces failures by creating unsafe pressure or worse food quality.

Step 9: assign ownership to each control

Prevention fails when every team assumes another system will catch the problem. Name the owner of address rules, delivery-zone changes, ETA messages, driver instructions, marketplace settings and incident review. For supplier-controlled features, record the support route and the evidence required for escalation.

Step 10: introduce changes in a controlled sequence

Do not change the address form, driver wait rule, customer messages and delivery zone on the same evening. Start with the highest-volume cause, test it on representative orders and keep the previous process available. Compare the same days and service periods where possible, while noting unusual weather, promotions or staffing.

Use a meaningful denominator

Report failures per completed delivery attempt, not only as a raw monthly count. Also report recovered incidents separately. A lower final failure rate can conceal more calls, longer driver waits or expensive redeliveries. Review the total operational burden and customer outcome together.
