Key takeaways
- Fulfilment sites hit the generator problem and the consumer problem on the same day, which is what makes peak expensive.
- Count one week of empties in July; most sites underestimate their own generation by about half.
- Clearance capacity is genuinely finite and books out from August. A July conversation costs nothing and holds equipment.
- Single-size carton lots are reusable stock worth forty cents to a dollar eighty each, not OCC worth a few cents a pound.
Every October we get calls from fulfilment operations that need three hundred bulk boxes this week, plus somebody to take away the eleven hundred empties currently blocking a door. Both are possible. Neither is cheap, and both would have been straightforward in August.
The two problems arrive together
This is the specific difficulty of peak in e-commerce and third-party logistics: inbound volume rises, which means more empties accumulating, at exactly the moment floor space becomes most valuable and staff have least time. The generator problem and the consumer problem peak on the same day.
A site that has not planned for it ends up paying for emergency clearance while also paying spot prices for containers, in the same week, having spent the preceding six weeks losing productivity to congestion.
The calendar that works
| When | Do this | Why then |
|---|---|---|
| July | Count one week of empties | Establishes the real generation rate before volume rises |
| Early August | Book clearance capacity for Sept – Dec | Equipment is still available; it will not be in October |
| Mid August | Reserve container stock against forecast | Standing rates rather than spot |
| September | Start scheduled fortnightly collection | Prevents accumulation reaching crisis level |
| October – December | Weekly collection, reverse-flow loads | Empties out, stock in, same visit |
| January | Post-peak clearance and reconciliation | Availability is good, rates are soft |
Why counting in July is the whole thing
Almost every fulfilment site underestimates its own generation of reusable containers, typically by about half. Bulk boxes arrive full and leave flat, so they are invisible in a way that pallets and cartons are not.
One week of counting in a normal month gives you a base rate. Multiply by your expected peak uplift and you have a number you can hand to a supplier, which converts an anxious conversation in October into a booked schedule in August.
The carton mistake
Single-size carton lots from one inbound programme are reusable stock, not recycling feedstock. Baled as OCC they are worth a few cents a pound. Sorted and bundled they are worth forty cents to a dollar eighty each.
During peak, when nobody has time to sort, those cartons go in the baler. The fix is not extra labour; it is a decision made in August about where the receiving team puts them, because they arrive already separated.
Returns, the January problem
Peak has a tail. Returns processing in January generates a second wave of mixed containers and cartons, usually in worse condition and more mixed than the inbound wave. Sites that plan for December and stop are dealing with that one at the worst time of year for staffing.
Build January into the schedule in August. It is the cheapest month of the year to move material, and nobody is competing for the trucks.
