Standard Purchase Orders: You generally create standard purchase orders for one-time purchase of various items. You create standard purchase orders when you know the details of the goods or services you require, estimated costs, quantities, delivery schedules, and accounting distributions.
It is recommended to choose a standard purchase order when you require vendor commitment to specific items/services, quantities and delivery schedules, but a long-term agreement is not appropriate.
Blanket Purchase Agreements: You create blanket purchase agreements when you know the detail of the goods or services you plan to buy from a specific supplier in a period, but you do not yet know the detail of your delivery schedules. You can use blanket purchase agreements to specify negotiated prices for your items before actually purchasing them. Blanket purchase agreements can be created for a single organization or to be shared by different business units of your organization (global agreements).
For many organizations it is sometimes referred to as “standing order” or an “open order”.
It is recommended to choose a blanket agreement when you’ve negotiated volume discounts and want to create releases against these negotiated volumes, or when you commit to specific items, quantities or amounts.
Blanket Releases: You can issue a blanket release against a blanket purchase agreement to place the actual order (as long as the release is within the blanket agreement affectivity dates).
Contract Purchase Agreements/Order: You create contract purchase agreements with your suppliers to agree on specific terms and conditions without indicating the goods and services that you will be purchasing. You can later issue standard purchase orders referencing your contracts.
It is recommended when a pricing negotiation on your entire volume of business. Use a contract to manage terms and conditions for this type of negotiation; couple it with a catalog quotation to reference pricing on a per item basis when you create standard purchase order lines.
Global Agreements: You may need to negotiate based on an enterprises’ total global purchase volume to enable centralizing the buying activity across a broad and sometimes diverse set of businesses. Using global agreements (a special type of blanket purchase agreement), buyers can negotiate enterprise-wide pricing, business by business, then execute and manage those agreements in one central shared environment. Enterprise organizations can then access the agreement to create purchase orders that leverage pre-negotiated prices and terms.
Planned Purchase Orders: A planned purchase order is a long-term agreement committing to buy items or services from a single source. You must specify tentative delivery schedules and all details for goods or services that you want to buy, including charge account, quantities, and estimated cost.
It is recommended to choose a planned purchase order when you want to encumber the order before creating releases. Also use to provide vendor scheduling for capacity management while issuing releases to confirm order commitment.
