Key takeaways
- Couriers bill on the higher of actual and volumetric weight — a light but bulky parcel costs more than it weighs.
- Discrepancy charges are back-dated, landing in remittances weeks later, so they’re easy to miss.
- Prevent them by measuring every SKU once and declaring the higher weight; right-size packaging.
- Dispute wrong ones fast with a scale-and-tape photo — the window is short.
Here’s a leak most Indian D2C brands never plug: you book a parcel at 400g, the courier measures it at 900g, and two weeks later a "weight discrepancy" adjustment quietly shrinks a remittance. Multiply that across hundreds of orders and it’s real money — and a meaningful share of those charges are simply wrong. Fixing this is half prevention, half dispute discipline. Let’s do both.
Why couriers charge on weight you can’t see
Shipping isn’t priced on mass alone — it’s priced on the more expensive of two numbers:
- Actual (dead) weight — what the parcel weighs on a scale.
- Volumetric (dimensional) weight — the space it occupies, because a truck fills up on volume, not just tonnage.
So a big, light item — a pillow, a puffer jacket, a bulky kurta set — gets charged on its size. If you declared only its scale weight, the courier’s measurement legitimately beats yours, and you get back-charged. That’s not always an error; sometimes it’s you under-declaring. The trick is knowing which is which.
Why the charges hit so late
Parcels get re-weighed as they pass through courier hubs, and those measurements are reconciled in batches. So an adjustment for something you shipped this week can show up in a remittance one to three weeks later. That lag is why weight discrepancy is so sneaky: if your reconciliation only looks at the current week’s orders, back-dated adjustments from a fortnight ago slide past unnoticed — and un-disputed. (This is the same reason your COD remittance sometimes comes up light for no obvious reason.)
Prevention: win before the charge exists
- Measure every SKU once, properly. Weigh it packed, measure L×W×H, compute volumetric, and record the higher of the two as your standard shipping weight.
- Declare the honest, higher weight at booking. Under-declaring to save a few rupees just invites a back-charge later — usually at a worse rate.
- Right-size your packaging. Air is volumetric weight you’re paying to ship. A snugger box or poly mailer can drop a parcel a whole slab.
- Photograph proof at packing for bulky/expensive SKUs — the parcel on a scale (weight visible) and against a tape measure (dimensions visible). This is your dispute evidence, ready in advance.
Dispute: reclaim the wrong ones
When a discrepancy charge is wrong, couriers will reverse it — but only if you raise it in time with proof. The window is short (often a few days to a couple of weeks), so this has to be a routine, not a someday.
- Catch it. Reconcile every remittance and flag any weight-discrepancy line, including back-dated ones from earlier shipments.
- Pull your evidence. The packed-parcel photo on a scale plus dimensions with a tape measure for that SKU.
- Raise the dispute on the courier panel within the window, attaching the evidence and your declared vs charged weights.
- Track it to resolution. Note the ticket, chase it, and confirm the reversal actually appears in a later remittance.
- Fix the root cause. If the courier was right, update that SKU’s standard weight so it never recurs.
Stop losing money to silent deductions
Kwikfy reconciles courier remittances against your real orders and flags weight-discrepancy adjustments and missing COD before the dispute window closes — so wrong charges get caught and challenged instead of quietly eating your margin.
Reconcile Shipping Free →Make it a habit, not a hunt
Weight discrepancy will never be zero — some of it is genuinely your bulky products — but the wrong charges are recoverable and the avoidable ones are preventable. Standardise your SKU weights, right-size packaging, keep evidence at packing, and reconcile every remittance for back-dated adjustments. Do that and one of the quietest leaks in Indian shipping turns into a line you control, not a surprise you absorb.
