How to Choose a Shipping Aggregator in India

Most Indian D2C brands pick a shipping aggregator the way they pick a payment gateway. Someone recommends one, the rate card looks fine, and the integration takes an afternoon. Eighteen months later the brand is losing two to four percent of revenue to weight charges, RTO deductions and remittance delays that nobody is reconciling.

An aggregator is a rate-buying and allocation layer. It buys courier capacity in bulk, resells it in slabs, and decides which courier gets your parcel. That last part matters more than the headline rate.

Read the rate card the way finance reads it

Every Indian courier rate card has three variables: the weight slab, the zone, and the mode.

Weight slabs start at 500g for most surface services. The first slab is priced higher than the additional slabs. A card quoting Rs 24 for the first 500g and Rs 22 for each additional 500g is not a flat Rs 44 per kilogram parcel. It is Rs 46. Check whether additional weight is charged in 500g steps or 1kg steps, because a 1.1kg parcel on 500g steps costs materially less than the same parcel on 1kg steps.

Zones usually run A through E. Zone A is intra-city, B is intra-state or a regional cluster, C is metro to metro, D is rest of India, and E covers the special zones, which in practice means the North East, Jammu and Kashmir, Ladakh, Andaman and Lakshadweep. Map your last ninety days of orders to the zone split before you compare cards. A brand with 40 percent Zone D volume gets a very different effective rate than the sample invoice on the sales deck.

Then the adders. COD fee is typically the higher of a flat charge or a percentage of order value, often around Rs 25 to Rs 40 or 1.5 to 2 percent. RTO is charged at forward rate or a discount to it, and some cards charge full forward plus a handling fee. Fuel surcharge floats, so read whether it applies to base freight only or to the total.

Aggregator surface rates in 2026 sit roughly between Rs 19 and Rs 26 per 500g depending on plan tier and monthly volume commitment. Direct rates from a national carrier above 1,000 orders a month land in a similar band, sometimes lower on Zone A and B.

Weight discrepancy is a process problem, not a pricing problem

Chargeable weight is the higher of actual weight and volumetric weight. Volumetric is length times breadth times height in centimetres divided by 5000 on most surface services. A courier hub reweighs and remeasures your parcel and raises a discrepancy if their reading is higher than your declared value. The charge appears as a deduction, usually weeks later.

You will not win these on argument. You win on evidence and on the clock. Dispute windows are short and vary by carrier, roughly seven to ten days at some and around fifteen days from invoice at others. Miss the window and the deduction is final.

What works: weigh and measure every parcel at packing on a calibrated scale, photograph the parcel on the scale with the AWB visible, store that image against the AWB automatically, and run a weekly reconciliation that flags every discrepancy above your tolerance. Brands that do this recover most of what is raised. Brands that do not simply absorb it.

Allocation, NDR and RTO are where the money sits

Allocation is the rule set that decides which courier carries which order. Default allocation optimises for the aggregator’s cost, not for your delivery rate. Ask whether you can set your own rules, and whether those rules can use pincode, payment mode, order value and category.

The rule you want is simple. High value and COD orders go to the courier with the best delivered percentage on that pincode cluster. Low value prepaid goes to the cheapest available. Review the split monthly against actual delivered rates, not promised ones.

NDR is the failed delivery attempt. Across Indian ecommerce, NDR rates run roughly 20 to 40 percent depending on category and payment mode. An unactioned NDR converts to RTO within 24 to 72 hours. Manual chasing recovers 10 to 20 percent of those orders. A structured workflow, meaning an automated call or WhatsApp within the hour, a customer-facing reschedule link, and a hard escalation before the third attempt, recovers 40 to 60 percent.

RTO is the outcome you are managing. India’s blended RTO sits near 23 percent. COD runs near 26 percent. Prepaid runs under 2 percent. Good COD operations hold 15 to 20 percent. Ask any aggregator for RTO percentage by courier on your own shipments. If they cannot produce it by courier, they cannot help you fix it.

COD remittance and when to go direct

COD money is your working capital sitting in someone else’s account. Cycles range from D+1 or D+2 at the fast end to D+7 or longer. The stated cycle is not the real cycle. What matters is the day count from delivery to money in your bank, measured over ninety days, and how much is held back against unresolved disputes.

Ask three questions before signing.

• What is the actual median remittance day over the last quarter for accounts of your size, not the marketing claim.
• What triggers a hold, and how are weight and RTO deductions netted off against remittance.
• Is there an early remittance product and what does it cost, because two percent for four days is a very expensive line of credit.

Go direct with couriers when three things are true. You ship above roughly 800 to 1,000 orders a day from a single origin, so a carrier will give you a dedicated pickup and a named account manager. Your zone mix is concentrated enough that one or two carriers cover most of it. And you have the operations bench to run label generation, manifesting, reconciliation and claims yourself, because that is the work the aggregator was doing.

Most brands should run both. Direct contracts with one or two carriers for the concentrated lanes, and an aggregator for tail pincodes and for redundancy. The aggregator earns its margin on coverage and on the day your primary carrier stops picking up.
