TAT (Turnaround Time) — The promised end-to-end delivery time on a lane — 'T+2' means delivered two days after pickup. Distinct from remittance T+N.

Why it matters to your store

Checkout promises should be built on realistic TAT + one buffer day, not the courier's best case. Under-promise at checkout, over-deliver at the door.

This is the vocabulary every courier invoice, NDR report and rate card is written in — learn it once, save money forever.

Worked example

Delhi→Bengaluru surface TAT is ~3 days → promise 4–5 → customer is delighted at 3.

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.
