Key takeaways
- Keep the accepted fuel quantity distinct from the financial settlement.
- Identify what a credit actually adjusts before changing any record.
- Resolve disputed quantities through the responsible evidence review.
- Preserve the original delivery reference when correcting an invoice.
Match the evidence to the actual service
TNPA's Durban service description distinguishes berth-specific pipeline and barge arrangements. TNPA Durban services
The reconciliation should use records belonging to the actual delivery. Do not substitute documentation from an assumed service method or another parcel simply because it names the same vessel and port.
For a current transaction, the quantity-and-credit reconciliation is not provided; obtain current verified information. Record the accepted quantity, relevant delivery references, invoice basis, credit purpose and any remaining disputed item.
Separate physical, pricing and service adjustments
A corrected quantity changes the quantity basis once supported and accepted through the appropriate process. A price adjustment changes what is charged for the accepted fuel. A service credit changes a separate commercial component or agreed settlement.
These adjustments can all reduce the payable amount, but they should not be treated as interchangeable. The reason for the reduction determines which records need to change.
A finance system may require a credit to be allocated to a particular invoice line. That accounting presentation does not itself establish the physical meaning of the credit. Preserve the underlying explanation rather than deriving a quantity change from the ledger layout.
ILLUSTRATIVE: a service credit leaves fuel quantity unchanged
ILLUSTRATIVE fictional transaction; no current Durban rate. Assume the accepted delivery is 500 tonnes at $600 per tonne, producing a product invoice of $300,000. The parties separately agree a $2,000 service credit while leaving quantity and product price unchanged.
The resulting net payable is $298,000. Dividing that amount by the original unit price produces approximately 496.667 tonnes, but that quotient is not a corrected delivery quantity. The accepted physical quantity remains 500 tonnes under the stated assumptions.
The review should retain the product invoice and separately identify the service credit. It should not manufacture a shortage from a financial adjustment.
Resolve the purpose before posting the correction
Ask which original charge or issue the credit addresses, which delivery it references and whether it is accepted as final or remains conditional. If the document describes a quantity correction but the supporting explanation describes a service settlement, obtain clarification.
Do not choose the interpretation that merely reconciles the accounts fastest. A mistaken quantity reduction can affect internal inventory, voyage consumption analysis and later commercial explanations even if the immediate payment total is correct.
Where the credit settles a dispute or affects rights, check the actual agreement and obtain appropriate review. The buying desk should not infer a waiver or final settlement from the existence of a credit note alone.
A correction-classification table
| Proposed adjustment | Evidence to identify | Record consequence |
|---|---|---|
| Accepted quantity correction | Supported revised delivery basis | Update quantity and linked financial calculation |
| Product price adjustment | Accepted revised pricing term | Preserve quantity; correct product value |
| Service credit | Defined service charge or settlement purpose | Record separately from physical fuel quantity |
| Duplicate invoice reversal | Duplicate reference and original valid invoice | Remove duplicated liability, not delivered fuel |
| Unresolved proposed credit | Conditional or disputed proposition | Keep the open status visible |
| Replacement document | Clear link to the superseded record | Prevent both versions entering the total |
Keep disputed quantity separate from an undisputed credit
The supplier may agree a service adjustment while a quantity disagreement remains open. Do not present that agreement as resolution of both issues unless the supported settlement says so.
Show the accepted and disputed positions clearly. The responsible reviewers need the actual delivery evidence and applicable terms to assess a quantity issue; procurement should coordinate those inputs without prescribing measurement procedures.
Finance also needs to know which amount is recognised for payment and which remains subject to review. That is a financial status, not a substitute for the underlying physical conclusion.
Preserve useful final comparisons
A final cost report can show gross product cost, separate adjustments and net purchase expense. This explains the commercial outcome without rewriting the delivery history.
If management wants an effective cost per accepted tonne, label that calculation as a financial ratio. It should not be confused with the original contractual unit price when separate credits are included.
The distinction becomes especially useful when comparing purchases. An exceptional service settlement should not silently become the expected fuel price for the next Durban enquiry. Carry forward the current quotation basis, not an unexplained net figure from a different transaction.
Common mistakes
Avoid converting every credit into fewer delivered tonnes, treating an accounting allocation as physical evidence and allowing original and replacement invoices into the same total. Another error is assuming a service credit resolves a separate quantity dispute. Identify what each correction actually changes before updating the record.

Frequently asked questions
Does a lower net invoice prove that less fuel was delivered?
No. Establish whether the adjustment concerns quantity, price, service or another defined item.
Can an effective cost per tonne still be useful?
Yes, if its financial basis is clearly labelled and the accepted quantity remains independently supported.
Should a proposed credit be treated as final?
Only when its actual acceptance and conditions support that status.
What belongs in the reconciliation slot?
Record delivery evidence, accepted quantity, credit purpose, corrected financial basis and unresolved disputes separately.
