Abstract: In a computer-implemented method of contract execution, data about contracts is stored in a computer storage accessible to a processor of a computer along with data about a procurement plan and data about a purchase request that includes information about a first quantity of at least one good or service. The processor determines a second quantity of the one good or service and a second contract against which to complete the purchase request based on the procurement plan, the data about the contracts, at least one purchase made against one of the contracts, a trigger condition and associated effect, and the quantity of at least one good or service. In response to the second contract and the second quantity being approved, the processor causes a purchase order for the second quantity of the one good or service to be placed to the supplier associated with the second contract.

Abstract: In a computer-implemented method of conducting expressive payment reconciliation, a purchase transaction is stored in a computer storage accessible to a processor. The processor identifies a contract against which the purchase transaction is made and a first payment amount for the purchase transaction. Contract data is stored in the computer storage and the processor determines a second payment amount for the purchase transaction based on at least one good or service associated with the purchase transaction and the data about the contract. In response to a difference in the first and second payments, the processor either stores computer storage a modified invoice with a modified payment amount, stores in the computer storage a reconciliation payment equal to the payment difference; outputs over a computer network an explanation of the modified payment; or outputs over a computer network a dispute notification.

Abstract: In a computer-implemented method of procurement strategy optimization, data about a number of contracts is stored in a computer storage accessible to a processor of a computer along with a forecast of a future quantity of at least one good or service to be purchased. The processor of the computer determines a first plan for future procurement against at least one of the stored contracts based on the forecast and the following data specified by the one contract: a good or service, a payment rule, a trigger condition, and an associated effect of the trigger condition. In response to the processor automatically approving the first plan subject to one or more predetermined rules or the processor receiving an approval of the first plan, the processor causes the first plan to be adopted for future procurement.
