3PL Billing: Stop Losing Storage and Handling Charges

3PL charges leak at month end because the work happens on the warehouse floor every day, but the billing gets pieced together from memory and spreadsheets weeks later. The fix is to record each charge at the moment the work is done: when you receive, put away, pick, pack and dispatch. Then month-end billing is a review, not a reconstruction.

Why do 3PL charges leak at month end?

Think about where the information lives. The receiving team knows they hand-unloaded a floor-loaded 40-foot container on a Tuesday afternoon. The pickers know a client's order needed 30 cartons relabelled. The supervisor knows a pallet came in damaged and someone spent half an hour photographing it and writing it up.

Accounts knows none of this. On the last day of the month, someone sits down with a system export, a few emails and a photo of the whiteboard, and tries to rebuild what happened. Storage is usually right because it is a simple count. The extras are where it falls apart: the one-off handling, the rework, the Saturday dispatch. If nobody wrote it down at the time, it does not get billed.

Nobody is being careless. The people doing the work are not the people billing it, and the gap between them is three or four weeks.

What counts as a storage or handling charge?

Storage charges are what the client pays for space over time: per pallet, per bin, per cubic metre, per week or per month. Handling charges are what they pay for work: receiving, putaway, picking, packing, loading, and everything in between.

Most rate agreements also carry a long tail of accessorial charges. These are the ones that leak, because they are irregular and nobody expects them until they happen.

Which 3PL charges are most commonly missed?

Run last month's invoices against this checklist. If you did the work but cannot find the line, that is money left on the warehouse floor.

• Devanning or hand-unloading floor-loaded containers
• Palletising loose cartons on arrival
• Re-palletising or re-wrapping damaged pallets
• Labelling or relabelling cartons and units
• Damage inspection and photo reports
• Sorting mixed SKUs received on one pallet
• Storage for part-months (goods in on the 20th still took up space)
• Pick fees per line, not only per order
• Packing materials: cartons, void fill, tape, pallets
• Kitting or bundling
• Returns receiving and inspection
• Cycle counts or stock takes the client asked for
• After-hours or weekend receiving and dispatch
• Cross-dock handling
• Special reports or extra admin requested by the client

Not every warehouse charges all of these. But if your agreement says you do, each one should appear on the bill when it happens, not when someone remembers.

How do you bill as you work?

Tie each charge to the event that causes it. Receiving a shipment is an event, so the receiving charge belongs to it. Putting a pallet into a bin starts it taking up space, so storage starts there. Picking an order is an event, so the pick charge belongs to that order.

When charges come from the work itself, nobody has to remember them later. The warehouse team does its job, and the bill builds up in the background.

That is how Lumen handles warehouse and 3PL work. You receive against what was expected, put away to bins, pick from lists sorted by bin, and dispatch. Handling and storage charges go to the client's bill automatically as each step is done. Freight charges from the client's shipments add to the same running total, so the whole relationship sits in one place.

How does receiving against expected protect your billing?

Billing disputes usually start at the dock. The client says they sent 24 pallets; you bill for 23 and they ask where the other one went. Or you bill for 24 and they later find one arrived crushed.

Receiving against what was expected settles this on day one. Before the truck arrives, you know what should be on it, from the commercial invoice or packing list. When your team counts, any shortage or damage is flagged right there, with photos attached.

An illustrative example: 24 pallets expected, 23 counted, one with a crushed corner. The shortage and the damage are both on the receiving record with photos, you tell the client the same afternoon, and the handling for the damage inspection is already on their bill. There is no argument at month end, because the evidence came from the dock, not from memory.

What should the month-end billing review look like?

Short. If charges have been building up all month, month end is a review of what is already there.

In Lumen, you look at charges per client: storage, handling and freight together. You check the list, adjust anything that needs a human call (a goodwill waiver, a disputed line), and create the invoice in one click. It is emailed to the client from Lumen. Clients pay by bank transfer, with card payments coming next. Once paid, the invoice closes.

Put that next to two days of spreadsheet archaeology and the difference speaks for itself.

How do you get the warehouse team on board?

Do not ask pickers and receivers to fill in billing forms. They will not, and you would not either. Make the charge a side effect of what they already record: confirming the receipt, confirming the bin, completing the pick list, marking the dispatch. If the system already knows a job was done, it should already know the job is billable.

This also changes how the floor team sees the system. It stops being something accounts nags them about and becomes the place where their work is counted.

Where do you start?

Pull last month's invoices for your three biggest clients. Run them against the checklist above. For each charge you did the work for but did not bill, ask where in the process it should have been captured: at receiving, at putaway, at pick or at dispatch. That list is your billing setup.
