Key takeaways
- Separate the invoice amount from a later or conditional rebate.
- Compare the same accepted delivery method, product and quantity.
- Identify what event earns the rebate and who confirms it.
- Show the outcome if the condition is not met, without inventing a probability.
Keep the local delivery scope consistent
An official 2018 APBA notice distinguishes non-fixed supply by tanker truck or barge. Spanish official notice
Use the dated notice only as context for checking the offered service basis. Current feasibility and permissions require appropriate confirmation; the notice does not establish today's availability for the vessel.
For a current transaction, the quote comparison is not provided; obtain current verified information. Identify the accepted service scope, payable amount, rebate conditions and evidence that any condition has been satisfied.
Ask what the quoted net price assumes
A supplier may present a price after an expressly agreed commercial adjustment. The buyer needs to know whether that adjustment applies immediately, depends on another purchase or is issued after settlement.
The answer changes both comparison and funding. A later credit can reduce the final cost without reducing the amount due on the original invoice. A conditional rebate can disappear if the specified event does not occur.
Do not infer a condition from promotional language or a previous purchase. Obtain the actual offer wording and resolve ambiguous treatment before approving the comparison.
Distinguish controllable conditions from uncertain outcomes
A condition tied to an authorised payment date may be within the buyer's planning control, although finance must confirm whether it can be met. A condition tied to a future voyage, aggregate purchase or another party's action may remain uncertain.
Avoid converting that uncertainty into an invented expected saving. Instead, show the defined outcomes and identify what evidence would justify changing the status from conditional to earned.
Where the legal meaning or enforceability is material, check the current agreed text and obtain appropriate advice. The comparison table should not resolve a disputed entitlement by selecting the most attractive interpretation.
Illustrative comparison with and without the rebate
ILLUSTRATIVE — fictional equivalent delivery propositions, not actual Algeciras prices or supplier terms.
For an accepted 500-tonne purchase, offer A is a firm $615 per tonne, totalling $307,500.
Offer B invoices $625 per tonne, totalling $312,500, and provides a $15-per-tonne rebate only if an expressly agreed condition is met. The rebate would be $7,500, making the final net cost $305,000.
If earned, B costs $2,500 less than A. If not earned, B costs $5,000 more. The buyer must fund B's stated invoice according to its terms rather than assume that the conditional net amount is immediately payable.
The example does not recommend assigning odds to the condition. It shows why presenting only the favourable outcome can misstate the decision and hide the downside the approving manager is accepting.
A rebate-review matrix
| Term | Question for the supplier or finance team | Comparison treatment |
|---|---|---|
| Gross invoice price | What is due under the accepted order? | Show the payable purchase amount |
| Rebate trigger | Which event earns the adjustment? | Keep conditional until supported |
| Eligible quantity | Does it cover all accepted supply or a defined part? | Apply only to the agreed basis |
| Settlement method | Credit, refund or immediate reduction? | Separate final cost from funding timing |
| Claim or processing requirement | What agreed step remains? | Assign responsibility without assuming completion |
| Failed condition | What price remains payable? | Show the unfavourable defined outcome |
Fictional case: the voyage programme changes
A fictional buyer compares an Algeciras offer containing a rebate linked to a later qualifying purchase. At approval, the later vessel call is only provisional, but the comparison ranks the rebate as already earned.
The voyage programme changes and the later purchase does not proceed. The supplier's treatment follows the actual agreed condition, leaving the first purchase more expensive than the alternative originally available.
The review does not assume wrongdoing by either party. It identifies a comparison error: the buyer approved a conditional benefit as though the required future event had already happened. A better approval would have shown both outcomes and the uncertainty explicitly.
Reconcile the benefit after delivery
Track the accepted rebate separately from fuel quantity and ordinary billing corrections. When a credit arrives, connect it to the eligible purchase and confirm that its amount reflects the agreed basis.
If no credit arrives, investigate the condition and processing status before treating the benefit as realised savings. Internal procurement reporting should distinguish negotiated potential savings from adjustments actually earned and recognised.
Common mistakes
Avoid comparing a firm price with only the favourable net outcome of a conditional offer. Other errors include assuming a rebate reduces the immediate advance, applying it to ineligible quantity and reporting it as realised before recognition. Keep the delivery scope equivalent so that the rebate does not conceal another commercial difference.

Frequently asked questions
Is a conditional rebate the same as a lower invoice price?
No. Its eligibility and settlement may differ, so show both the payable amount and conditional final cost.
Should the buyer estimate the probability of earning it?
Only with a defensible basis and an appropriate purpose. Clear outcome scenarios are often more useful than invented odds.
Can the rebate be applied to every grade automatically?
Only if the accepted terms support that scope. Confirm the eligible quantity and product basis.
What belongs in the rebate-comparison slot?
Record the gross price, condition, eligible scope, recognition status and payment treatment.
