A Supplier Scorecard in Four Columns

Most supplier problems arrive as a feeling rather than a fact: this one is getting slow, that one keeps sending the wrong thing. A scorecard turns the feeling into four numbers. On-time delivery, order accuracy, response time to a query, and price movement over twelve months. Each takes about a minute a month, and together they survive a difficult conversation far better than memory.

Four numbers beat a page of narrative

Measure on-time as the percentage of lines arriving on or before the date you were promised, not the date you hoped for. Measure accuracy as the percentage of lines arriving correct in quantity and specification. Both should be counted by line item, because a single faulty pallet can hide inside an otherwise clean order.

Response time is the easiest to record and the most revealing. Note how long a routine query takes to get a substantive reply, meaning an answer rather than an acknowledgement. Suppliers who answer within a day usually handle exceptions well. Suppliers who take four days are the same ones who go quiet when a shipment is stuck.

Cheapest quote and best supplier are different rankings

Compare the lowest unit price against the cost of the errors that price brings. A supplier ten percent cheaper who misses one delivery in five may cost more once you count expedited freight, customer apologies and staff time. Put an estimated cost beside each failure on the scorecard and the cheaper supplier often stops looking cheap.

Actionable step: share the scorecard with the supplier before the review, not during it. Give them a month to respond. Suppliers who engage with the numbers tend to improve within a quarter, and the ones who dispute every line are telling you something useful about the next negotiation.

Scores flatten when you have one supplier

A scorecard is only useful when you have somewhere else to go. With a single source, a bad score changes nothing, and everyone knows it. Build a second qualified supplier for your two most critical lines before you start scoring, otherwise the exercise becomes paperwork that nobody acts on.
