Key takeaways
- Compare equivalent product and service scope before converting currencies.
- State the direction and source of the conversion used.
- Separate an analytical exchange assumption from a secured settlement rate.
- Test whether plausible alternative inputs reverse the ranking without forecasting them.
Fix the service scope before the currency calculation

The offers should concern the same actual service point and requirement. A currency conversion cannot repair a comparison between different quantities, specifications, delivery arrangements or payment dates.
For a current transaction, the currency-normalised comparison is not provided; obtain current verified information. Record original offer currencies, complete amounts, authorised conversion basis, relevant fees, payment conditions and remaining exchange exposure.
Preserve the original quotations
Keep each supplier's original currency and amount visible alongside the analytical equivalent. This allows the reviewer to reconstruct the comparison and prevents an internally converted value from being mistaken for the seller's accepted price.
Identify whether the quotation fixes the amount in its stated currency or permits a later conversion under an agreed mechanism. A fixed unit price in one currency may still leave the buyer exposed in its reporting or funding currency.
If the seller accepts payment in another currency, obtain the actual conversion term. Do not assume that the buyer may settle using whichever rate appears most favourable at payment time.
Use the correct rate direction
The comparison must state whether the rate expresses local currency per unit of reporting currency or the reverse. Applying multiplication where division is required can produce a materially wrong total even when the quoted rate itself is correct.
Use finance's authorised basis for the decision and identify whether it is indicative or executable. If no settlement rate has been secured, preserve that uncertainty rather than presenting the converted total as fixed.
Include relevant agreed transaction expenses without inventing bank fees. Where a fee remains unknown, show the total as conditional on that component.
ILLUSTRATIVE: the ranking changes with the conversion input
ILLUSTRATIVE fictional offers and exchange assumptions; no current Shanghai prices or currency rates. Assume an equivalent approved parcel of 500 tonnes. Offer A totals $305,000. Offer B totals CNY2,150,000. Assume converting and settling B also incurs a fictional $1,000 expense.
At an assumed CNY7.10 per US dollar, B converts to approximately $302,816.90 and totals $303,816.90 after the expense, or $1,183.10 below A.
At an assumed CNY7.00 per US dollar, B converts to approximately $307,142.86 and totals $308,142.86, or $3,142.86 above A.
The arithmetic divides the yuan amount by yuan per dollar. Neither assumed rate is a forecast or executable quote; the example only demonstrates the unresolved exposure.
Compare payment dates as well as currencies
If one proposition requires earlier payment, its funding consequence may differ even after the currencies are normalised. Keep any authorised funding calculation separate from the exchange conversion so the result remains understandable.
The buyer also needs to know when the final currency amount becomes fixed and who is responsible for arranging settlement. A favourable analytical comparison can become stale before that point.
Do not recommend a financial instrument or assume that a hedge exists merely to eliminate the uncertainty in the worksheet. Use the buyer's actual authorised treasury arrangement and qualified advice where needed.
A currency-comparison table
| Comparison item | Evidence or definition needed | Error prevented |
|---|---|---|
| Original offer | Currency, amount and complete scope | Losing the seller's actual proposition |
| Conversion direction | Currency units in numerator and denominator | Reversing the calculation |
| Rate status | Indicative or secured basis with date | Treating an estimate as executable |
| Payment date | Accepted due condition | Ignoring different funding exposure |
| Additional expense | Applicable settlement fees | Comparing a net amount with an incomplete total |
| Alternate settlement | Supplier-accepted conversion mechanism | Making a unilateral payment adjustment |
| Final invoice | Original contractual currency and adjustments | Rewriting the order using internal reporting figures |
Explain the decision's remaining uncertainty
A recommendation can identify the offer that is lower under the authorised current comparison while stating that exchange exposure remains. If the ranking is sensitive, show the relevant scenarios rather than claim a durable saving.
The approving person should understand whether the decision accepts that uncertainty, requires a secured conversion basis or depends on another supplier proposition. The desk should not hide the choice inside a single converted number.
After payment, distinguish exchange movement from product-price variance and service-cost variance. Otherwise the next buying review may attribute a treasury outcome to supplier performance or carry an obsolete converted unit price into a new enquiry.
Common mistakes
Avoid reversing the rate direction, mixing payment dates without explanation and using an indicative rate as a secured price. Other errors include omitting settlement expenses, replacing original quotations with internal converted figures or treating exchange movement as a change in the supplier's product price.

Frequently asked questions
Does a fixed foreign-currency price fix the buyer's reporting cost?
Not necessarily. Establish the actual conversion and settlement basis.
Can a public reference rate be used as an executable quote?
Do not assume so. Use the authorised basis and preserve its status.
Should the original currency remain in the comparison?
Yes. Keep it visible alongside the analytical equivalent and relevant assumptions.
What belongs in the currency slot?
Record original amounts, equivalent scope, conversion direction, rate status, fees and payment timing.
