If you have ever picked a courier based on price alone—and then spent weeks dealing with RTOs, delayed deliveries, and billing surprises—you already know why this decision needs more thought than it usually gets.
Your courier is the last touchpoint between your store and your customer. Everything before that — your product, your packaging, your ad spend — leads to that one moment at the door. If the delivery experience is bad, the customer remembers your brand, not the courier.
Here are the five things every seller should check before choosing a courier partner.
This is the first question, and most sellers skip it entirely.
"Pan-India coverage" is a phrase every courier uses. But what it means varies drastically. Some couriers cover 8,000 pin codes. Others cover 19,000 or 27,000+. If your customers are ordering from Tier 2 or Tier 3 cities — and increasingly they are — that gap matters.
Before you finalize any courier, pull your last 2–3 months of order data and list your top delivery pin codes. Share that list with the courier and ask two things: do they service these pin codes directly, and what is the expected delivery time for each?
If a courier services a pin code through a third-party partner, your transit time goes up and your control over the delivery goes down. That is worth knowing upfront.
Also ask about ODA (Out of Delivery Area) charges separately—these are extra fees for remote or difficult-to-reach locations, and they are often not mentioned in the initial rate quote.
The rate a courier quotes in a sales call is almost never the rate you actually pay per shipment.
Here is what gets added on top:
Dimensional (volumetric) weight — If your product is light but takes up space (think apparel, toys, home décor), couriers charge based on volume, not actual weight. The formula is length × breadth × height ÷ 5000 for surface and ÷ 4000 for air. A product weighing 300g but packed in a large box can be billed at 800g or more.
Fuel surcharge — This is a percentage added to every shipment, typically 12–25%. It changes periodically. Always ask if the quoted rate includes a fuel surcharge or not.
COD handling fee — If you offer cash on delivery, the courier charges a fee to collect and remit the payment. This is usually 1–2% of the order value with a minimum flat amount per shipment. It adds up significantly on smaller order values.
COD remittance cycle — This is not a charge, but it affects your cash flow. After the courier collects cash from your customer, how many days before it reaches your bank? Some couriers settle in 1–3 days. Others take 7–14. The slower the cycle, the more working capital you have tied up at any given time.
RTO charge — If a delivery fails and the package comes back, you pay the return shipping cost on top of the forward shipping cost you already paid. Know this rate before you commit.
Ask for the full rate card in writing and calculate what your actual per-shipment cost looks like across your real order mix—not the best-case scenario the courier pitches.
Every courier promises fast and reliable delivery. What you want is their actual on-time delivery (OTD) rate, broken down by zone.
OTD rates in metro cities from good courier partners typically run 92–96%. In non-metro areas, the same courier might deliver 75–82% on time. During peak seasons—Diwali, Navratri, and year-end sales—performance drops further as networks get stretched.
Ask for:
If the courier cannot or will not share this data, that is your answer.
Also check independent reviews — not testimonials on their website. Seller communities on Facebook, WhatsApp groups, and forums are more honest. Other sellers who have shipped the same routes and product categories will tell you what the experience is actually like.
One practical note: delivery speed matters beyond customer satisfaction. The faster a package is delivered, the less time a COD customer has to change their mind. Faster delivery directly reduces your RTO rate.
Shipping is not just physically moving a parcel. It is also the workflow around it — label creation, order sync, tracking, customer communication, and NDR management. A courier with poor technology creates hidden operational costs that most sellers do not account for when comparing prices.
Before choosing a courier, check:
Platform integration — Does the courier connect directly with your selling platform (Shopify, WooCommerce, or wherever you sell)? If you have to manually download orders and upload them to the courier's portal every day, that is an hour of daily work that scales into a real problem as your orders grow.
Tracking quality—Does the courier provide scan-level tracking updates, or does the status only change once a day? Can your customer track their order independently through a link, or do they have to call you?
NDR dashboard — When a delivery fails, can you see it immediately and take action? Can you reschedule, update an address, or confirm cancellation from one place? Or do you have to call the courier's helpline and follow up manually?
Customer notifications — Does the courier automatically notify your customer when the shipment is picked up, in transit, and out for delivery? Or does your team have to do this separately?
Poor technology multiplies your support burden. Every "Where is my order?" query that comes to your team is a query that good courier technology would have already answered for the customer.
RTO (Return to Origin) is what happens when a delivery fails and the package comes back to you. It is one of the most expensive recurring costs in Indian eCommerce, and it is directly connected to which courier you choose.
When a shipment returns, you pay:
Across India's eCommerce market, average RTO rates sit at 20–25%. In COD-heavy categories like fashion, footwear, and home décor, they often run higher. If your current RTO rate is above 15–20%, your courier's delivery attempt policy and NDR management are worth examining.
Before choosing a courier, ask:
The standard is 3. Some couriers make only 1–2 before triggering RTO. That is a structural problem, not a one-off issue.
Does the courier automatically notify you and the customer? Is there a system to reschedule? Or does a failed delivery just quietly move toward RTO without your knowledge?
If a customer needs to return a product, how does the reverse pickup work, how much does it cost, and how long does it take to reach your warehouse?
Every courier loses or damages some packages. What matters is how they handle it—how you file a claim, what documentation is required, and how long settlement takes.
These are not edge-case scenarios. They happen every day at scale, and the courier's policies around them have a direct impact on your margins.
If you are shipping across multiple states or selling through multiple channels, you may find that no single courier is ideal for every order. A courier that is strong in metros may underperform in Tier 2 cities. A courier with great pricing may have poor NDR management.
This is where a courier aggregator makes sense. Instead of managing separate contracts with multiple couriers, an aggregator connects you to multiple courier partners through one platform—so you can select the right courier for each order based on pin code, price, and performance.
Shipmozo is one such platform. It is a courier aggregator built for eCommerce sellers that connects to 27+ courier partners, covers 29,000+ pin codes, and gives you rate comparison, label generation, tracking, COD management, and NDR handling from a single dashboard. It integrates with Shopify, WooCommerce, and other platforms directly, which removes the manual order-upload step entirely.
It is worth mentioning because it addresses several of the checks above in one place—particularly the technology and RTO handling gaps that cost sellers the most in day-to-day operations. That said, the five checks above apply whether you use an aggregator or work directly with a courier.
Ask for serviceability confirmation for your specific top 30–50 pin codes, not a general "pan-India" claim. Ask whether coverage is direct or through a third-party partner — because partnered coverage usually means longer transit times and less accountability when something goes wrong.
The gap is usually dimensional weight, fuel surcharge, or ODA charges that were not in the original quote. Ask for an itemized rate card that includes all applicable surcharges. Then run your actual product dimensions and order data through it to see what you will really pay per shipment.
At minimum, 3 attempts. A courier that triggers RTO after 1–2 attempts, without proper NDR follow-up or customer communication, is significantly inflating your return rate and your costs. This is one of the most important operational questions to ask before choosing a courier.
For prepaid orders, under 10% is achievable. For COD orders, industry average is 20–25%, but sellers with good courier choices and proactive NDR management can bring this below 15%. Anything above 30% consistently suggests a problem with either the courier, the product, or the ordering process.
For sellers shipping under 100–150 orders a month, one courier is usually manageable. As volume grows and your customer base spreads across more geographies, using multiple couriers—or an aggregator that allocates the right courier per order—typically gives better delivery performance and pricing.
After a courier collects cash from your customer, they hold it and remit it to your bank account on a cycle—typically every 2, 7, or 14 days depending on the courier and your agreement. The longer the cycle, the more working capital is tied up in transit. For sellers with high COD volumes and tight margins, this can create a real cash flow problem. Ask this question before you commit, not after.
NDR stands for Non-Delivery Report. It is generated when a delivery attempt fails—because the customer was unavailable, the address was wrong, or the customer refused delivery. An unresolved NDR typically converts to an RTO within 24–72 hours. If your courier does not have a clear NDR management process and a way for you to take action quickly, you are losing orders that could have been recovered.
Start with the five checks in this blog. Then ask each courier for their rate card, serviceability data for your top pin codes, OTD rate by zone, and their NDR/RTO policy in writing. If possible, run a pilot of 100–150 shipments before committing your full volume. Real performance data from your own orders is more reliable than any sales deck.
Direct contracts make sense if you have high, consistent volume and can negotiate good rates. Aggregators like Shipmozo make more sense if your volume is mixed, you ship to diverse geographies, or you want the flexibility to switch couriers per order without managing multiple relationships. Most growing sellers find aggregators more practical until they reach a point where dedicated courier contracts become worth the effort.
Document everything — the shipment weight, dimensions, value, and packaging. File the claim as soon as the loss or damage is confirmed. Good couriers have a clear claims process with defined timelines. Ask about this before you choose a courier — not after your first loss.
Choosing a courier is not a one-time decision you set and forget. As your order volume grows, as your customer base spreads, and as your product mix changes, your courier requirements will evolve. The five checks above—coverage, real pricing, delivery performance, technology, and RTO handling—give you a framework to evaluate any courier at any stage and to switch when your current partner stops meeting your needs.
The best courier for your store is the one that reliably gets your products to your customers, at a cost your margins can absorb, with enough visibility and control for you to manage problems when they happen.
