The share of third-party spend that procurement sourced, contracted or approved, from payables joined to the contract register and the approved supplier list. Three buckets, on contract, approved off contract and unmanaged, sum to total spend. The denominator that makes a savings claim honest.
An approved supplier at list price is a separate bucket from a negotiated contract.
Dropping it flatters the figure. List it.
Invoices with a contracted supplier, in force on the date, covering the category, through the agreed channel, divided by addressable spend.
Of $112 million addressable, invoices passing the test total $61 million: 54 percent. The self-reported figure was 82.
A category counted as managed because a contract exists somewhere in it.
