NDR (Non-Delivery Report) — The courier's daily list of shipments that failed delivery — customer unreachable, address issue, refused, out of area. Each NDR needs a response or it becomes an RTO.
Why it matters to your store
NDR is your rescue window. Most couriers hold a failed shipment 2–4 days; a fast response (call the customer, fix the address, re-attempt) converts a would-be RTO into a delivered order.
This is the vocabulary every courier invoice, NDR report and rate card is written in — learn it once, save money forever.

'Customer not available' NDR → WhatsApp the customer → confirm tomorrow → re-attempt marked → delivered. That workflow is the difference between 25% and 15% RTO.
The bottom line
Shipping jargon is really just the billing manual in disguise — every term on this list maps to a line on an invoice or a lever on your margins. Pakka Parcel is built so you rarely have to think about it: statuses normalise, bills reconcile, and quotes already include the surcharges.
