Dirty Product Quotes: Define the Additional Service

Overview

A cargo pack may contain requirements that lead to further commercial discussion. The analyst should not assume that those requirements are included in every quote, nor invent the technical method or cost of meeting them. The comparison needs the responsible parties' scoped responses before it can show what the buyer is actually purchasing.

Key takeaways

• Identify the requested service using the current cargo and programme references.
• Distinguish included scope, separately priced scope and unresolved obligations.
• Check whether an additional amount overlaps another quoted component.
• Keep technical feasibility and commercial price as separate decisions.
• State the assumptions that would reopen the recommendation.

Start with the requested obligation

Read the enquiry and cargo-source information together. Identify any requirement beyond the base description of the movement and ask who has authority to clarify it.

The commercial desk should preserve the requirement's source without prescribing how the vessel or terminal performs the work. If a heating-related or other cargo-specific service is discussed, for example, the responsible specialists determine its technical basis. The analyst records what service the parties have actually offered or requested.

Avoid a generic additional services column that conceals different obligations. One bidder may include a defined scope, another may require separate agreement and another may be waiting for information before responding.

Those states should remain visible in the comparison. An unresolved obligation is not equivalent to a zero price, and a separately quoted amount is not automatically an unnecessary premium.

Clarify the price basis of each component

For every additional amount, identify the service scope, currency, calculation basis and approval process. Ask what event makes the charge applicable and what evidence supports its calculation.

Do not infer those terms from a familiar label. A fixed amount, reimbursement basis and quantity-linked charge represent different commercial structures. Their treatment should come from the actual offer or agreement.

Where wording is unclear, check the current text and obtain authorised commercial or legal review. The analyst should not settle the interpretation through a convenient spreadsheet assumption.

The table lets management compare complete propositions rather than a collection of numbers whose scope is unclear.

Check overlap before calculating totals

A common comparison error occurs when an additional estimate is added to an offer that already includes the same service. The opposite error occurs when an analyst assumes inclusion because the service appears in the enquiry, even though the bidder has not accepted it.

Reconcile the components with the offering party's clarification. Keep the response reference beside the model so a reviewer can see why an amount is included or excluded.

If the buyer has a separate arrangement for the service, identify that scope too. The transport offer may not need to provide an output already covered elsewhere, but the authorised commercial team should confirm the relationship.

Do not treat overlap as purely mathematical. Two similarly named components may cover different work, while differently named lines may represent the same obligation. Follow the definitions rather than the labels.

Keep review status alongside the cost view

The existence of a quoted amount does not establish that the proposed service has completed the necessary technical or receiving review. Ask the responsible parties what conditions remain.

A bidder may provide an indication for planning while waiting for a cargo clarification. Record that limitation and identify the information source able to close it.

Conversely, a specialist's positive response does not settle the commercial allocation of cost. The desk needs the relevant offer terms or authorised agreement as well.

The recommendation should show both readiness and economics. If an offer is preferred subject to a named response, state the owner and next decision point. Avoid hiding a feasibility dependency inside a broad contingency allowance.

Use scenarios that reflect the real programme

Test only the additional-service cases the business is genuinely considering. If the requested scope changes with a different cargo or destination, obtain a scoped response rather than applying the original amount automatically.

Keep planning estimates separate from counterparty commitments. The business may need an internal provisional total, but it should know which components are not yet offered on a confirmed basis.

If the preferred offer changes depending on an unresolved component, explain that sensitivity in plain language. Management can then decide whether to seek clarification, adjust the programme or choose a proposition with a clearer basis.

A comparison need not force a single winner before the critical information is available. It can identify the exact question whose answer will determine the choice.

Fictional case: the same service is counted twice

A fictional dirty-products buyer receives a freight proposal that expressly includes a defined cargo-related service. The operations team separately obtains a planning estimate for a similar requirement and sends it to the analyst.

The analyst adds the estimate to every offer to create an all-in comparison. The selected offer appears less attractive than it did before, but the model does not explain whether the extra line overlaps its included scope.

A reviewer asks the offering party and operations team to reconcile the definitions. They confirm that part of the estimate is already covered while another requested item remains separate. The analyst corrects the total and records the clarification.

The result is not simply a lower number. It is a more accurate description of what the buyer would obtain and what remains to be arranged under each proposition.

Hand over the agreed scope

After selection, provide the incoming coordinator with the current offer, additional-service definitions, approval process and evidence requirements. Identify any component still estimated or subject to later agreement.

Preserve the cargo and programme references that govern those terms. A later change may require the service scope or price basis to be revisited.

Keep the original clarifications available. A short handover note should not erase the conditions that prevented double counting or resolved an apparent exclusion during comparison.

A post-movement review can then ask whether the quoted scope matched the service actually requested and whether the team obtained the necessary evidence for settlement. That is more useful than comparing only the final total with the earliest headline price.

Common mistakes

Treating an unresolved service requirement as zero cost makes an incomplete offer look comparable with a developed one.

Another mistake is to add an estimate without checking whether the selected offer already includes the same scope.

Finally, avoid using a quoted service price as proof of technical feasibility. The commercial amount and the responsible review decision answer different questions.
