AI & Manual NDR Management for Ecommerce Sellers
BlitzShipz offers both AI NDR management and manual NDR management, so you can save orders that fail at the doorstep. When an order enters NDR, your team gets a WhatsApp NDR alert, your customer can get a call from our AI caller, our calling team or a dedicated team member, and you can request a reattempt from one dashboard, usually for the next day.

What Is NDR Management and How Does It Work?
NDR management is the process of following up on every failed delivery so the parcel gets delivered on the next attempt instead of going back to you. An NDR (Non-Delivery Report) is raised when the courier makes a delivery attempt but cannot hand over the parcel, usually because the customer was not available, the address was wrong or incomplete, the phone was not reachable, or the customer refused the parcel.
AI NDR management uses an AI voice caller to reach every customer quickly. Manual NDR management uses trained people to call customers, which helps when a case needs a human conversation. BlitzShipz lets you use either one, or both.
On BlitzShipz, it works in four steps. Your team gets a WhatsApp alert the moment an order enters NDR. The customer gets a call to find out why the delivery failed. You fix the address, phone number or delivery time in Dashboard → NDR. Then you request a reattempt, which the courier usually schedules for the next day. For the full list of reason codes and prevention tips, read our guide on how to reduce NDR in ecommerce.
It pays to reduce failed deliveries fast. A failed delivery you do not fix usually turns into an RTO, and an RTO means you pay shipping twice and still lose the sale. No tool can save every order, and a customer who has changed their mind may still refuse the parcel. For more ways to protect your margins, read how to reduce RTO in ecommerce.
AI NDR Calling vs Manual NDR Calling vs a Dedicated NDR Calling Team
Choosing between AI vs manual NDR calling depends on your order volume and team. AI calling reaches every customer quickly, manual calling adds a human voice for tricky cases like refusals, and a dedicated NDR calling team handles your whole NDR queue for you.
| AI Calling | Manual Calling | Dedicated Team | |

| Who calls the customer | An AI voice caller | The BlitzShipz calling team | A BlitzShipz employee assigned to your account |
| Best for | Sellers who want every NDR called quickly | Sellers who want a human voice on every call | Brands with a high NDR volume or a large COD share |

With AI calling, the AI caller reaches the customer once the feature is switched on, asks why the delivery failed, and saves the recording on your seller panel. With manual calling, the BlitzShipz calling team places the calls instead. With a dedicated team, one BlitzShipz employee is assigned to your account, rather than a shared pool, and handles the calling as a managed service.

Manage Undelivered Orders from One Dashboard
Every undelivered order from every courier partner sits in one NDR tab, so your team works from one list instead of several courier portals.
- WhatsApp NDR alerts: Your team gets a WhatsApp NDR alert as soon as an order enters NDR. Choose which team members get alerts in your communication settings.
- NDR reason and recording: See why each delivery failed and listen to the AI call recording before you act.
- Request a reattempt: Update the address, phone number or delivery time and click “Reattempt”. The courier usually schedules the new attempt for the next day, though timing can vary by courier.
- Better courier choice: AI courier selection weighs delivery success rates to send future orders through the courier that delivers best in that area.
Orders that sync from your Shopify or WooCommerce store through our integrations, or come in through the Open API, go through the same flow. Wix integration is coming soon. If the customer still cannot take the parcel, our reverse pickup and RTO handling brings it back to you in a tracked way.
In short, alerts and AI calls give you automated NDR management, and our calling team steps in whenever you want a human on the line.
Pay only for what you use. NDR alerts and AI calls are charged from your BlitzShipz wallet as they are used, and they switch on after your first wallet recharge. Manual calling and a dedicated team member are priced on your order volume, so talk to our NDR team for a plan that fits.
