Couriers regularly overcharge by inflated 'measured' weights. Learn the per-AWB reconciliation playbook that recovers 4–9% of your monthly shipping spend.
Every Indian D2C merchant pays an invisible "weight tax" of 4–9% on their shipping bills. Courier dimensional-weight machines drift, parcels get re-weighed at hubs, and pricing teams shave fractional kilograms across millions of shipments. The result: a billed weight that's consistently higher than the actual weight you shipped.
This tax doesn't appear as a line item — it's hidden inside the chargeable-weight column on your monthly invoice. And because no human can manually audit 10,000+ shipments a month, most merchants never reconcile.
Weight reconciliation is the process of comparing the expected weight of each parcel (from your packed SKU + packaging data) against the billed weight the courier reports, identifying discrepancies beyond tolerance, and filing claims to recover the overcharge.
The recovery math is straightforward:
Across a year, that's ₹18–₹46 lakh — which directly drops to gross margin.
You need a "ground truth" weight per SKU + packaging. The two practical ways:
Either way, you need a per-SKU expected weight before reconciliation can begin.
For every shipment, capture: expected_weight, billed_weight, dim_weight_billed, chargeable_weight. Any AWB where billed > expected + tolerance (typically 50g for parcels under 1kg, 100g for 1-5kg) is flagged as overcharged.
India's volumetric divisor is 5000 (L × B × H / 5000). If billed weight equals or exceeds volumetric weight, the courier is correctly billing volumetric — don't claim. If billed weight exceeds both actual and volumetric, that's an overcharge and is claimable.
Each courier has its own claim format and timeline:
Submitting individually is a full-time job. Bundling weekly per courier reduces operational cost.
Most couriers settle 70-85% of valid claims within their SLA. The other 15-30% need escalation: photo evidence, dispatch manifest, or a polite tier-2 email. Maintaining a tracker (open / partially-paid / closed / disputed) is essential.
Recovered amounts can be credited against next month's invoice or remitted to your bank. Either way, book the recovery as "Shipping cost reversal" in your P&L, not as "Other income" — it preserves the true cost of shipping in your unit economics.
If your reconciliation shows recurring overcharges on a single SKU, the bug may be in your expected weight, not the courier's measurement. Things to check:
A good reconciliation workflow re-audits expected weights quarterly.
ShipyBox's Weight Reconciliation module automates this entire flow — per-AWB comparison, claim bundling, evidence collection, courier-specific submission templates, and credit tracking. Merchants typically recover ₹1–4 lakh in their first reconciliation cycle.
