What Is Purchasing? Definition, Process, and Examples

Purchasing is the process of acquiring goods or services for a business, identifying a need, selecting a supplier, and completing the transaction, usually by issuing a purchase order. It is the transactional part of buying, and it sits inside the broader function of procurement. The simplest example is a company’s day-to-day buying, like ordering a laptop from CDW or Amazon Business.

In short: purchasing is the act of buying goods or services a business needs, from raising the request to issuing the purchase order and receiving the goods. Procurement is the wider strategy around it — sourcing suppliers, negotiating contracts, and managing vendor relationships. Purchasing is one step inside procurement, not a synonym for it.

For instance, buying a laptop from CDW or Amazon.com illustrates the purchasing process. The main activity in the purchasing process is to complete the purchase transaction.

A buyer can finalize the transaction by issuing a purchase order to the vendor, placing an order through a website, or simply calling the vendor.

Whether an organization issues a purchase order depends on its maturity. A small company might not have a formal purchase order process, while a growing company typically issues purchase orders to vendors.

Importance Of Purchasing In Business

Purchasing is crucial for maintaining operational efficiency and managing business spending effectively.

It ensures that the right products and services are procured at the right prices, contributing to cost savings and supporting the long-term goals of the organization.

A well-defined purchasing process aligns with the overall corporate strategy and supports effective financial management.

Key Differences Between Purchasing And Procurement

While often used interchangeably, there is a significant difference between procurement and purchasing.

Purchasing is a subset of procurement, focusing specifically on the transaction of buying goods and services.

In contrast, procurement encompasses the broader process of identifying needs, sourcing potential suppliers, negotiating contracts, and managing supplier relationships.

Differences:

Purchasing: Involves the act of acquiring goods and services.

Procurement: Encompasses the entire process from identifying needs to managing supplier relationships and ensuring compliance with organizational policies.

 

Examples of purchasing

Purchasing covers any business buy, from routine supplies to large one-off orders. Common examples:

• Office and facility supplies — reordering printer toner, coffee, or cleaning supplies from Staples or Grainger.
• IT equipment — buying laptops and monitors from CDW for a new hire.
• Lab or production inputs — a biotech ordering reagents from Thermo Fisher against a project budget.
• MRO items — maintenance parts from McMaster-Carr to keep equipment running.
• Services — engaging a contractor or software subscription through a purchase order.

In each case the purchasing process is the same: a need is identified, a request is raised and approved, a purchase order is issued, and the goods or services are received and matched to an invoice.

Steps In The Purchasing Process

The purchasing process varies from company to company. A small company might not have a process at all, while a large company might have a highly bureaucratic process.

Here are the key steps in the purchasing process:

1. Need Identification

The first step is determining what needs to be purchased and why. For example, a new laptop may be needed for a new hire.

2. Requesting Quotes

This step involves obtaining quotes from different potential suppliers to assess the best value. Quotes can be obtained formally or informally through vendor websites.

3. Purchase Order Approval

The purchase order approval process ensures that a manager or appropriate person approves the purchase. This step is critical for budget checks and verifying the necessity of the purchase.

4. Issue Purchase Order Using Purchase Automation

After purchase approval, a buyer can issue a purchase order to the vendor. While optional for small companies, larger firms typically use purchasing systems for this purpose.

It’s good to know that having a purchasing automation process in place can truly help your organization have a smooth sailing process.

5. Track Purchase Order Lifecycle

Tracking the purchase order through its lifecycle involves monitoring order acknowledgments and shipment tracking.

Once received, a Goods Receipt Note (GRN) is created to assist the Accounts Payable team with the three-way matching process.

Roles And Responsibilities in Purchasing

An operation or dedicated purchasing team is responsible for purchasing functions. The size and complexity of the organization often dictate whether there is a dedicated purchasing department.

Purchasing Managers

Purchasing managers oversee the purchasing process, ensuring compliance with organizational policies and strategic objectives.

Buyers

Buyers in purchasing are responsible for sourcing products and negotiating contracts. Their role includes evaluating suppliers and making purchasing decisions.

Purchasing Agents

Required Education And Certifications

While education requirements can vary, many positions in purchasing prefer candidates with a background in business or finance. Certifications in procurement or supply chain management can enhance career prospects.

The Formal Solicitation Process

The formal solicitation process involves inviting bids for products and services. This structured approach allows organizations to evaluate multiple suppliers and select the best options based on predetermined criteria.

Vendor Management Strategies

Effective vendor management strategies are crucial for building strong vendor relationships. Organizations should regularly assess supplier performance and engage in open communication to maintain healthy partnerships.

Benefits of Group Purchasing

Group purchasing allows organizations to leverage collective buying power, resulting in cost savings and improved supplier terms. By collaborating with other entities, organizations can access volume buying power and better pricing.

Challenges In the Purchasing Process

Several challenges can arise in the purchasing process, including managing supplier relationships, ensuring compliance with procurement policies, and navigating conditions of scarcity.
