Comparing supplier quotes in different currencies

An USD quote and an EUR quote cannot be ranked by looking at the numbers alone. First confirm that each covers the same quantity, specification, and delivery responsibility. Then choose a comparison currency and one dated rate source for the worksheet.

Keep two views

Preserve each supplier's original currency and price next to the converted estimate. Record the rate, date, fees, and whether your business can hedge or pay from that currency. Do not treat a conversion as a supplier commitment. A quote valid for 30 days and an exchange rate observed today have different clocks.

Test the decision

Recalculate at plausible rates to see whether the preferred offer changes; those are scenarios, not forecasts. If the ranking is fragile, consider whether the supplier can quote in the currency in which you budget or whether a shorter decision window is acceptable. Confirm the payment currency in the purchase order so the comparison does not quietly become a different transaction.

Worked conversion record

Supplier A quotes USD 9.00; Supplier B quotes EUR 8.20 for the same 500-unit scope. Record a dated, independently sourced EUR-to-USD rate and payment fees outside the tool, then enter both converted USD values in the comparison tool with “USD” as common currency. Preserve the original EUR quote in your decision sheet. Common error: typing 8.20 into a USD field and letting the tool compare unlike currencies. Re-run the conversion before award if the rate or validity period changes.
