A quantity-three label is the same size as a quantity-one label, with the same barcode and the same address block. The only thing that says three is one digit in the Qty column — and if it is missed, the seller finds out as a return.
Tick Multi Quantity Order at last and Circle it. Part of the free crop — no coins.
Nothing goes wrong at the start of a batch. It goes wrong at parcel one hundred and forty, inside a rhythm of one label, one item, tape, next — and that rhythm is exactly what a multi-quantity order breaks. The digit is printed on the label. It is simply not where someone moving at speed is looking, and one short-packed parcel costs more than the sale it came from.
Grouped at the back, they stop being interruptions and become a job: a short, dense run of nothing but multi-quantity orders, arriving when the packer is already in counting mode. Two of the same, then three of another, each with its count circled — checked against the batch and finished in one pass. Scattered through the file, every one of them is a stall in a rhythm that was working.
If you also sort by Courier Partners, sending a Valmo label to the very end of the file would land it after the Delhivery block and quietly break a handover you had already counted. So the push stops at each partner boundary instead: multi-quantity labels go last inside their own courier run, and every pile stays intact. The same applies with Label with Invoice, which takes no crop at all and keeps each page whole — the ring is still drawn on it.
