Ten orders a day can be fulfilled any way at all. Fifty reveals that your method does not scale.
Print in batches
Select all ready orders and print their waybills together. The gap between batch and individual printing becomes obvious after the twentieth order.
Order waybills the way you pack
Print in the same order as products sit on the shelf. Staff walking the warehouse in random order waste more time than you would guess.
Check before sealing, not after
Make it a rule: the waybill goes on after the parcel contents are matched to the order, never before. Most "wrong item" errors happen because the label went on first.
Standardise handover
Agree a fixed daily pickup time with your carrier. Ad-hoc pickups mean parcels waiting an extra day for no reason.
Log what is late and why
Keep a simple list: which orders missed handover and why. After two weeks your real bottleneck will surface — and it usually is not the carrier.
