What form will you use to notify the purchasing department on the items it need to order their quantity and the timeframe?

You may already know that purchase orders are used by companies to improve business spend management and control - but were you aware that several different types of purchase orders exist?

There are four primary types of purchase orders used by businesses. The selection of which type of purchase order should be used is determined by how many details are known about the order prior to the placement of that order, and subsequent purchases

The four types of purchase orders are:

  • Standard Purchase Orders (PO)
  • Planned Purchase Orders (PPO)
  • Blanket Purchase Orders (BPO) (Also referred to as a “Standing Order”)
  • Contract Purchase Orders (CPO)

In this article, the functions of these different purchase order types will be reviewed, along with a few situational examples of when and how each type may be used to support different methods of purchasing required goods and services.

Terminology and concepts to understand before reading

There are a few terms and concepts that are sometimes used when talking about these different PO types.

Legally Binding

All purchase orders become legally binding documents once they’ve been confirmed and accepted by the supplier receiving them. This means that any terms, conditions or other details included in the PO must be adhered to by both the buyer and the supplier once the PO has been issued.

Encumbrance

This accounting term refers to reserving business revenue for future use. When planning out certain types of POs, encumbrance is sometimes used to plan out the expenditure for the order.

While encumbrance is an accounting function, it can pay to understand the concept in depth from a purchasing perspective. Here are some great sources for further reading on the topic:

  • What does “encumbered” mean in accounting?
  • What is "encumbrance" in accounting?
  • What is an “encumbered expenditure open item”?

Accounting Distributions

Accounting distributions in a purchasing environment refer to monetary amounts issued to specific general ledger (GL) accounts - allowing for better categorization of documented expenditures in accounting records.

Release

This term refers to creating a “release” against (or in other words, in relation to) a standing purchase order type. Effectively, some types of purchase orders act as a set of pre-established ordering information, terms, and conditions, while the “release” is the act of placing an order based on those already established agreements.

To combine a few of these different terms, “encumbering a release” means that accounting is reserving the funds necessary to pay for a release order against an active purchase order.

Thankfully, with all of this supporting terminology out of the way, it’s time to take a look at the different types of purchase orders in depth.

The Four Types of Purchase Orders Include:

1. Standard Purchase Orders (PO)

Standard purchase orders are (not surprisingly) the most used type of purchase order, and the easiest to understand.

Standard purchase orders are comparable to "vanilla" orders in purchasing.

What form will you use to notify the purchasing department on the items it need to order their quantity and the timeframe?

The use case for a standard PO often falls under the need for a sporadic order, one-off purchases, and orders where the details of the order are exceptionally important.

Despite sometimes being raised responsively to certain situations, standard POs are the most detailed PO type and are used in situations where businesses are very certain about the requirements surrounding a purchase.

It’s worth noting that sometimes, for very basic purchasing requirements, filing an expense record can be far more efficient in some businesses than raising a PO. This is because PO documents are sometimes associated with time-consuming company purchasing policies, which make filing a basic expense record a more time-effective option than a PO for bypassing the procedures associated with them.

What information and details are included on a standard PO?

A standard PO typically includes these details:

  • Terms and conditions of the order
  • The list of which items will be purchased
  • The quantity of each item
  • The price of each item
  • The delivery date for each item (or for the entire PO)
  • The delivery location for each item (or for the entire PO)

Example of a standard PO being used:

If an office ran out of printing paper and/or ink cartridges, based on the scale of the company, a standard PO may need to be raised and provided to a purchasing manager for approval before those items were purchased from a supplier.

Depending on company policy, for a small order of these items, the PO may be kept as a reference document, while the items are purchased and picked up directly from the supplier.

For a very large order of printing paper and/or ink cartridges, the PO may be sent to the supplier to have the order delivered to a specific office location on a specific date.

Again, depending on company policy, a PO may not be raised at all for a small order of these items, and instead, a basic expense record may be filed to reduce processing time, while maintaining accurate purchasing records.

2. Planned Purchase Orders (PPO)

A planned purchase order (PPO) contains all of the same details and information as a standard PO, but omits delivery information. This means that the date and location for each item is not included in the creation of a PPO.

All of the other details are committed to by the buyer, including which items will be purchased, the quantity of each item, and the price of each item. This also means that if items are being purchased in batches, bundles, or sets, that the quantity of those groups

When the delivery information for some or all of the items is confirmed, what’s known as a “release” against the PPO is created to confirm the details of the delivery schedule.

Releases that are created against a PPO are referred to as “schedule releases”.

What form will you use to notify the purchasing department on the items it need to order their quantity and the timeframe?

PPOs may sometimes include unconfirmed tentative schedules, but these schedules must always be confirmed by a release prior to the order being confirmed for delivery.

What information and details are included on a PPO?

A PPO typically includes these details:

  • Terms and conditions of the order
  • The list of which items will be purchased
  • The quantity of each item
  • The price of each item

A PPO sometimes includes these details:

  • An unconfirmed, tentative delivery date for each item (or for the entire PO)
  • An unconfirmed, tentative delivery location for each item (or for the entire PO)

A PPO does not include:

  • Confirmed delivery dates for each item (or for the entire PO)
  • Confirmed delivery locations for each item (or for the entire PO)

Example of a PPO being used:

A retail business may intend to regularly purchase 120 items of a certain type each year to sell. The retail business may establish a PPO with a supplier, including a tentative schedule to order 10 items each month throughout the year. The items may be confirmed to be purchased in sets of 10, with a fixed price for each set of items purchased.

However, these monthly purchases would not be carried out until the retail business creates a release against the PPO to confirm the delivery date and location for each order even though a tentative delivery schedule exists.

3. Blanket Purchase Orders (BPO)

First and foremost, blanket purchase orders are sometimes known as “standing orders”.A blanket purchase order (BPO) is the same as a PPO, but in addition to omitting delivery information, a BPO also omits the item quantity and (sometimes) the item price. The list of what items will be purchased is still included in a BPO.

Similar to a PPO, a release that includes item quantities, item prices, delivery locations, and delivery times for each item type must be created against an established BPO before any form of purchasing or delivery can take place from the arrangement.

Releases that are created against a BPO are referred to as “blanket releases”.

What form will you use to notify the purchasing department on the items it need to order their quantity and the timeframe?

In most cases, when a BPO is established with a supplier, a maximum time frame that the BPO will be valid for is determined, alongside a maximum quantity of items that will be ordered within that time frame. In some cases, discounts are provided when certain item quantity thresholds or milestones are passed through multiple releases within the lifespan of the BPO.

Use-cases for a BPO typically arise in situations where unpredictable purchasing circumstances may make forecasting exact requirements difficult or impossible.

What information and details are included on a BPO?

A BPO typically includes these details:

  • Terms and conditions of the order
  • The list of which items will be purchased

A BPO sometimes includes these details:

  • Discounts and discount milestones based on item quantities purchased
  • Confirmed pricing details for each item

A BPO does not include:

  • Confirmed delivery dates for each item (or for the entire PO)
  • Confirmed delivery locations for each item (or for the entire PO)

Example of a BPO being used:

As a few examples, services that rely on mechanical components that may potentially break down without notice, or businesses that require components like printing paper and ink in order to serve an undetermined number of clients with varying volume requirements would benefit from establishing a BPO with their primary suppliers.

In both cases, the BPO is established to account for the uncertain requirements surrounding when and how frequently the items may need to be purchased.

As with a PPO, releases against the established BPOs would be required before any purchasing or delivery took place.

4. Contract Purchase Orders (CPO)

A contract purchase order (CPO) is somewhat similar to both the PPO and BPO, but for this type of purchase order, even the list of items required for purchase are omitted from the arrangement.

What form will you use to notify the purchasing department on the items it need to order their quantity and the timeframe?

There are a few distinct differences between contract purchase orders when compared to planned purchase orders and blanket purchase orders.

Most notably, the function of a CPO is exclusively to serve as a set of legally binding reference terms, which subsequent POs that reference the CPO will be bound to.

Additionally, the creation of POs against a CPO is not commonly referred to as a “release”, contrary to the term used for PPOs and BPOs (standard POs are simply "raised" or "created" against the established contract).

Typically, the only thing confirmed between a buyer and a supplier when establishing a CPO are the legal terms and conditions surrounding future POs that are raised in reference to the CPO. Some CPO arrangements have validity time frames specified, while other times these terms and conditions may remain available for reference indefinitely between a buyer and a supplier.

In essence, CPOs can be considered to be high-level, long-term purchasing agreements established to facilitate ongoing business between a buyer and a supplier.

What information and details are included on a CPO?

A CPO typically includes these details:

  • A set of negotiated and confirmed terms and conditions, from which subsequent purchase orders may be created

A CPO does not include:

  • The list of which items will be purchased
  • The quantity of each item
  • The price of each item
  • The delivery date for each item (or for the entire PO)
  • The delivery location for each item (or for the entire PO)

Example of a CPO being used:

CPOs are the most flexible of any PO type.

As one of an infinite number of different examples that could be made for a CPO, a buyer and a supplier might negotiate a set of terms that states that the buyer can order items from the supplier at a 50% discount during events that the buyer hosts, provided that the supplier is listed as a sponsor for the event.

Again, the use case of a CPO is solely to establish long-term purchasing terms and conditions.

What form will you use to notify the purchasing department on the items it need to order their quantity and the timeframe?

In summary

POs, PPOs, BPOs, and CPOs all serve the same purpose of enhancing the function of purchasing within a business, but do so in different ways.

POs are used to specify the highest level of detail when issuing the order.

PPOs and BPOs are used to establish purchasing arrangements over a period of time, with some specifics known about the order(s) released against them.

CPOs are used to establish terms and conditions, which multiple standard POs can be released against.

Understanding how and when to use each type of purchase order is an essential part of an effective financial management strategy for any mid-sized organization, and can also help scaling companies establish effective policies early on while building relationships with their suppliers.

What form should I use to inform the purchasing department about it?

A purchase requisition is an internal document used by employees to inform department managers about the resources they need. This document is then used by department managers to notify the purchasing department that they can start the purchasing process.

When notifying the purchasing department the needed items to order which appropriate form should be used?

One of the internal documents used for departments making a purchase is a purchase requisition form. Using this form allows teams to give vital purchasing information to the purchasing team, who can then place accurate orders on behalf of the rest of the organization.

What are the forms of purchasing?

There are two main purchasing forms – the Purchase Requisition and the Purchase Order. Both are standard forms that are used within a large company used to enable the efficient functioning of the purchasing department. The first of the purchasing forms is the Purchase Requisition.

What is a purchase order form?

A purchase order form is an official contract document in which a buyer agrees to purchase goods or services from a vendor. Purchase order forms are crucial because they standardize the business' procurement process.
