Choose a courier partner by testing it on your own orders. Check serviceability and delivery success on the pincodes you ship to most, compare fully loaded cost per delivered order, and get COD remittance, weight-dispute, NDR and claims terms in writing. Then run a 30-day pilot before moving volume, because no courier is strongest on every lane.
What should you look for in an ecommerce courier partner?
Use this checklist in every courier conversation. The middle column is what to ask; the last column is the answer that should make you pause.
| Criterion | What to ask | Red flag |
|---|---|---|
| 1. Serviceability on your pincodes | Can you serve my top 50 delivery pincodes, for prepaid and for COD, from my pickup pincode? | They quote a national pincode count instead of checking your list |
| 2. Delivery success rate | What share of shipments on lanes like mine were delivered, and delivered on the first attempt, last quarter? | Only a network-wide average, with nothing lane-level |
| 3. TAT vs promise | What delivery time do you promise by zone, and how often do you meet it? | The same TAT quoted for metros and the North-East |
| 4. Pickup reliability and cut-off | What is the daily pickup cut-off, and what happens when a pickup is missed? | No named contact or escalation for missed pickups |
| 5. COD remittance cycle | How many days after delivery is COD remitted, and is faster remittance extra? | The cycle isn't written into the agreement, or remittances arrive without a statement |
| 6. Weight-dispute process | How do you measure weight, what evidence do you share, and how long do I have to dispute? | No scanner photos or dimensions provided with a discrepancy |
| 7. NDR handling and reattempts | How many reattempts, over what window, and can I send instructions before RTO? | Parcels marked for return after a single attempt |
| 8. RTO charges | Is return freight charged at the forward rate, a discount or more? Is the COD fee reversed on RTO? | RTO charges missing from the rate card |
| 9. Rate card structure | What are the weight slabs, zone definitions, fuel surcharge and remote-area charges? | A headline rate with surcharges 'as applicable' |
| 10. Integrations and API | Do you plug into my store or shipping platform, and is there an API for booking and tracking? | Labels generated manually on a portal, with no tracking feed |
| 11. Claims and liability | What is your liability per shipment for loss or damage, how do I claim, and how long does settlement take? | A low liability cap with no option to declare value or insure |
| 12. Support and escalation | Who is my day-to-day contact, and what is the escalation matrix above them? | A generic helpline and nothing else |
Start with item 1. Pull your top delivery pincodes from the last three months of orders and run them through a pincode serviceability checker before you spend time on anything else. A courier that can't serve a fifth of your demand is a secondary courier at best, however good its rates.
Why does one courier rarely fit all your lanes?
Courier networks are built from hubs, line-haul routes and last-mile delivery centres, and each courier has invested more in some regions than others. One may be very strong in metro-to-metro express and thinner in tier-3 towns; another may have dense coverage in the South and fewer delivery centres in hill states. Product mix adds another layer: fragile items, high-value parcels, heavy shipments and COD all suit some couriers better than others.
So the right question isn't which courier is best, but which courier is best for this lane, this weight and this payment mode. You can see how the trade-offs shift between networks in our comparisons of Delhivery vs Blue Dart, Delhivery vs XpressBees and Ekart vs XpressBees, and browse each network's profile on the courier partners page.
How do you compare couriers on cost?
Compare on fully loaded cost per delivered order: freight on every order, plus COD fees, plus return freight on orders that come back, divided by the orders that actually got delivered. Our breakdown of how courier charges are calculated covers each line of the rate card.
A worked example with stated assumptions. You ship 100 COD orders on one lane, the COD fee is ₹35 per delivered order, and return freight is charged at the forward rate.
- Courier A charges ₹78 and delivers 80 of 100. Freight ₹7,800 + COD fees ₹2,800 + return freight on 20 parcels ₹1,560 = ₹12,160, or ₹152 per delivered order.
- Courier B charges ₹88 and delivers 90 of 100. Freight ₹8,800 + COD fees ₹3,150 + return freight on 10 parcels ₹880 = ₹12,830, or ₹143 per delivered order.
The courier that looked ₹10 more expensive is about ₹9 cheaper per delivered order, before counting the product damage, packaging and buyer goodwill lost on every returned parcel. Delivery success is a cost line, not a separate metric.
How do you run a 30-day courier pilot?
- 1Pick the lanes. Choose the zones or the 20–30 pincodes that make up most of your orders, plus one difficult lane such as the North-East or a hill state.
- 2Fix the slice. Send a set share of orders on those lanes (say every third order) to the new courier and keep the rest on your current one, so both handle the same mix.
- 3Agree terms before day one: rate card, COD remittance cycle, RTO charges, weight-dispute window and an escalation contact.
- 4Measure the same things for every courier: pickups made on time, first-attempt delivery, overall delivery, TAT against promise, NDR reasons, weight disputes raised and won, and COD remitted on time.
- 5Review weekly and raise problems with the courier. How fast and how well they respond is part of the test.
- 6At day 30, calculate fully loaded cost per delivered order for each courier on each lane.
- 7Set routing rules from the results: which courier gets which lanes, weights and payment modes, and which one is the fallback.
- 8Re-test every quarter and before the festive peak, because courier performance on a lane shifts over time.
Step 7 is where most sellers stop short. Doing it by hand in a spreadsheet works for a few hundred orders; past that, you need rules that assign a courier to each order automatically, which is what automated courier selection does.
What mistakes do sellers make when choosing a courier?
- Choosing on the 500 g headline rate and ignoring COD fees, RTO charges and surcharges.
- Accepting national averages for delivery success instead of numbers on their own lanes.
- Moving all volume to a new courier at once, with no pilot and no fallback.
- Not reading the liability clause until a high-value parcel goes missing.
- Skipping the weight-dispute terms, then losing months of small overcharges.
- Never re-testing, so a courier that was best two years ago keeps lanes it no longer deserves.
Frequently asked questions
No single courier is best for every seller. Delhivery, Blue Dart, DTDC, XpressBees, Ekart, Shadowfax and others each have stronger and weaker lanes, and performance depends on your pincodes, parcel weights and COD share. The best courier for you is the one with the lowest fully loaded cost per delivered order on your lanes, found through a pilot.
Many growing sellers use two or three: a primary courier for most lanes, a second for regions or weights where the primary is weaker, and a fallback for disruptions and festive peaks. A multi-courier shipping platform makes this easier, because you manage every courier from one account instead of separate contracts and portals.
Ask whether it serves your top pincodes for prepaid and COD, its delivery success on lanes like yours, its promised TAT by zone, the pickup cut-off, the COD remittance cycle, how weight disputes work, how many delivery reattempts it makes, how RTO is charged, every surcharge on the rate card, its liability for loss or damage, and who handles escalations.
For most small and mid-sized sellers, an aggregator gives more courier choice, pooled rates and one integration. Direct contracts can work out cheaper at high volume when one courier serves most of your lanes well. Our explainer on [what a shipping aggregator is](/blog/what-is-a-shipping-aggregator) compares the two side by side.
