Identify whose invoice is in question
For a warehouse or 3PL whose storage line has been short-paid or queried: the receivable is yours, and the charge needs its rate version, count basis and activity record before it can be explained to the customer. A customer checking its provider's bill runs the same check from the other side; a customer's proposed adjustment is not an approved credit.
Match entity, warehouse/site, account, service period and storage category. Obtain the applicable agreement and rate version, including count timing, minimums and agreed special-service charges.
Connect the rate to the activity
Connect the invoice line and unit definition to the storage report. Explain period movements with receipt, dispatch and inventory records. Separate returns, components and finished goods when the applicable method does.
Check special work against its authorization and completion record. Keep corrections and posted credits linked to their original lines. A missing rate version, cutoff date or activity record leaves a question; do not invent a daily rate or silently remove the charge.
Synthetic example: thirty pallet-days to explain
Invented agreement and USD amounts, not DCL or Jay Group rates. Assume this agreement bills daily occupied pallets at USD 2 per pallet-day, with no minimum or extra charge in this example.
| Check | Invoice | Supplied activity record |
|---|---|---|
| Pallet-days | 150 | 120 |
| USD per pallet-day | 2.00 | 2.00 per assumed agreement |
| USD total | 300.00 | 240.00 calculated |
The USD 60 difference corresponds to 30 pallet-days. Ask for the dated count detail and check missing receipts, dispatch cutoffs or corrections. The supplied record may be incomplete; USD 60 is not an established overcharge or approved credit.
Do not substitute another provider's method
DCL's help article describes a first-business-day monthly count, separate categories and prorated GAP receipts. Jay Group discusses pallet and cubic-foot billing. These are provider-specific examples of why units and timing matter; neither establishes the method for your agreement.
Use the evidence register's file/page and missing-record fields; its deduction headings are adaptable working labels. The short-payment tool checks a separate invoice/cash/credit bridge. It does not calculate storage quantities or decide a vendor dispute.
