Reading Spend Files Before a Rebid
What sourcing teams in Thailand should check in a twelve-month purchase history before inviting suppliers to a new bid round.
A rebid starts long before the RFP goes out. The spend file tells you whether volumes are stable, whether a few large orders skew the average, and whether units of measure are consistent enough to compare quotes.
Begin with line-item completeness. Missing supplier legal names, blank SKUs, and free-text descriptions that change every month make unit-price comparisons unreliable. Clean those rows first, even if it means a half-day with the category owner.
Next, separate one-off projects from recurring demand. Project spend can look like growth when it is really a warehouse fit-out that will not repeat. Flag those lines so the bid volume reflects what suppliers will actually ship next year.
Finally, mark contract-covered lines versus spot buys. Spot prices often hide the true baseline. When the rebid scorecard uses an inflated baseline, claimed savings later look larger than the invoice trail supports.
