Gibraltar Bunker Documents: Correct the Right Record

Key takeaways

• Distinguish the requested purchase from evidence of the completed supply.
• Link quality documents to the offered or delivered parcel being assessed.
• Identify which records an amendment actually changes.
• Preserve unresolved differences rather than making every document appear identical.

Use dated guidance within its proper scope

Gibraltar Port Authority's March 2020 circular identifies requisition, quality and delivery records within its bunker-document guidance. GPA circular 4/2020

Check the current text and obtain appropriate review where obligations or dispute rights matter. The dated document provides context for the different record types; it does not establish today's complete requirements for a particular transaction.

For a current transaction, the delivery-document reconciliation is not provided; obtain current verified information. Record the relevant delivery reference, outstanding differences and responsible reviewer, rather than publishing confidential attachments in a market-facing field.

Separate the requested quantity from the delivered quantity

The enquiry and accepted order describe the intended purchase. The final delivery record describes the recorded supply. A difference between them needs explanation, but the order should not be retrospectively rewritten merely to conceal that difference.

First identify whether the difference reflects an agreed amendment, an accepted variation, an incomplete supply or a disputed record. Those possibilities lead to different commercial actions. An open balance may require another delivery, whereas an accepted reduction may require only a revised invoice basis.

A desk that changes the order quantity before understanding the event can lose the evidence needed to explain why the invoice differs from the original commitment.

Connect product evidence without forcing matching labels

A certificate may use a batch reference while the order uses a purchase reference and the delivery document identifies the vessel call. Different identifiers do not necessarily describe different products, but an unsupported assumption that they match is equally unsafe.

Ask for the documented connection between those references. The relevant technical reviewer should assess the product evidence and any substantive description difference. Procurement can establish that the correct records are present and linked; it should not substitute its own quality conclusion.

If an attachment is replaced, identify whether the replacement corrects a clerical reference or changes the evidence relied upon. A new file name alone does not explain the significance of the amendment.

Correct a billing error at the billing level

An invoice can contain the wrong unit price even when the recorded delivery quantity is accepted. In that case, the commercial correction should address the price and resulting payable amount, with the underlying delivery evidence left clear.

Conversely, a corrected invoice does not establish that a disputed quantity has been resolved. If the supplier reduces its charge commercially, record the basis of that adjustment rather than presenting it as a new measurement conclusion.

The distinction matters for later performance analysis. A goodwill adjustment, accepted pricing correction and revised delivery record should not all become an unexplained negative quantity in the fleet database.

A document-difference decision table

The table helps assign the right question. It does not determine contractual rights or instruct anyone how to perform physical measurements.

Fictional case: a credit disguises the remaining question

A fictional Gibraltar delivery has an accepted commercial order, a final supply record and an invoice. The buyer challenges a charge and separately asks the supplier to explain a product-reference mismatch.

The supplier issues a credit for the charge. The accounts team marks the whole delivery file resolved because the net invoice now matches its expected payment.

During review, the desk separates the issues. It records the credit against the billing difference and keeps the product-reference question with the responsible reviewer. Payment treatment follows the applicable agreement and authorised decision; neither the credit nor the internal status label is presented as proof that the product evidence is complete.

Make the final file useful for the next reviewer

The close-out note should explain the accepted purchase, the recorded supply, the final billing basis and any unresolved exception. It should also identify which document is authoritative for each purpose.

Avoid creating a single combined number that hides a quantity adjustment inside a price adjustment. Another reviewer should be able to understand the transaction without reconstructing it from attachment timestamps or informal messages.

Common mistakes

Frequent errors include rewriting the order to match the invoice, treating a credit as a technical finding and accepting a replacement certificate without identifying its parcel. Another mistake is assuming dated port guidance settles current obligations. Keep commercial corrections scoped and obtain appropriate review of unresolved factual or legal questions.
