A purchasing manager needs to keep stock available, control costs and maintain good supplier relationships. But supplier information is scattered across emails, approvals take too long, and purchasing decisions rely on spreadsheets that are already out of date.
The result can be costly: stockouts, excess inventory, rushed orders and spending outside approved processes.
A structured procurement process helps businesses avoid these problems by creating a clear workflow for identifying requirements, selecting suppliers, approving purchases and reviewing supplier performance. For inventory-based businesses, it also depends on knowing what the business is likely to need before an order is placed.
This guide explains the procurement process, its key steps and stages, common challenges and how better planning and automation can support more informed procurement decisions.
What is the procurement process?
The procurement process encompasses all the steps an organisation takes to identify, evaluate and acquire the goods and services it needs.
It starts before an order is placed and continues after goods or services have been received. Depending on the organisation, procurement can include identifying requirements, evaluating and negotiating with suppliers, obtaining internal approval, creating purchase orders, receiving goods, processing payment and reviewing supplier performance.
Procurement is therefore broader than simply buying something.
Procurement vs purchasing: What is the difference?
Procurement and purchasing are closely related, but they are not interchangeable.
| Procurement | Purchasing |
|---|---|
| Covers the wider process of acquiring goods and services | Focuses on the transaction itself |
| Includes planning and identifying requirements | Includes placing and processing orders |
| Covers supplier evaluation, selection and negotiation | Usually begins once a supplier and requirement are established |
| Considers supplier relationships, risk and performance | Focuses more closely on completing the purchase |
| Strategic and operational | Primarily transactional |
Purchasing is one component of procurement. An effective procurement strategy considers the wider relationship between demand, suppliers, inventory requirements, cost and business objectives.
This makes procurement an important part of broader supply chain management.
Types of procurement
Procurement can be divided into two broad categories: direct procurement and indirect procurement. The distinction depends on how the goods or services being purchased contribute to the organisation’s operations and end products.
| Type | What it covers | Examples |
|---|---|---|
| Direct procurement | Goods and materials directly connected to the products a business sells or produces | Raw materials, components, finished goods for resale and packaging |
| Indirect procurement | Goods and services needed to run the business but which do not become part of the product sold | Office supplies, software, professional services, facilities and equipment |
Direct procurement is particularly closely connected to inventory management. Businesses need to determine how much stock or material they will require, when it will be needed and when orders should be placed with suppliers.
Demand forecasting, inventory planning, lead-time management and replenishment are therefore important inputs into direct procurement decisions.
AGR is primarily relevant to procurement decisions involving inventory and physical goods. It helps businesses understand future demand and translate it into inventory and replenishment requirements before purchase orders are created.
Key stages of the procurement process workflow
The exact procurement process varies according to the size, structure and needs of a business. However, most procurement workflows can be broken into seven core stages.
1. Need recognition and specification
The procurement process starts when the business identifies a requirement for a product or service.
The team needs to establish exactly what is required, how much is needed and when it is needed. Specifications may also include quality requirements, delivery conditions, budgets or other criteria suppliers must meet.
For inventory-based businesses, this stage should be informed by more than current stock levels. Demand forecasting can help businesses anticipate future requirements so procurement decisions reflect expected demand rather than simply responding to shortages after they occur.
Clear requirements make the later stages of procurement easier and reduce the risk of unnecessary or incorrect purchases.
2. Supplier evaluation, negotiation and selection
Once requirements are clear, procurement teams identify and evaluate potential suppliers. Price matters, but the decision should also consider factors such as quality, reliability, lead times, capacity and service levels.
Negotiation is an important part of this stage, covering areas such as pricing, payment terms, minimum order quantities and delivery schedules. But effective procurement starts well before the negotiation itself. As Keith Wright, author of The Power of Professional Procurement, explains, good procurement starts with understanding what the business actually needs and making better commercial decisions.
Strong negotiation is not simply about securing the lowest unit price. The goal is to agree terms that work for the wider business and support a dependable supply relationship.
Better visibility into future purchasing requirements can also strengthen these conversations. When buyers understand how much they are likely to need over the coming months, they can give suppliers greater visibility and potentially negotiate more favourable prices, quantities or delivery terms.
Once the preferred supplier and terms have been agreed, the procurement process can move towards internal approval and purchasing.
3. Purchase requisition and internal approval
The next stage is to formally request approval for the purchase.
A purchase requisition typically records what needs to be purchased, the quantity, expected cost, supplier and reason for the purchase. It is then routed to the appropriate person or department for approval.
Clear approval processes help organisations control spending and ensure purchases are authorised before commitments are made to suppliers.
4. Purchase order creation
Once a purchase is approved, a purchase order can be created and sent to the supplier.
The purchase order records important information such as product descriptions, quantities, agreed prices, delivery dates and payment terms.
Accurate purchase orders give both parties a clear record of what has been agreed and reduce the risk of misunderstandings later in the process.
5. Receipt of goods or services
When the order arrives, the organisation checks that the supplier has delivered what was agreed.
For physical inventory, this may involve confirming quantities, checking products for damage and ensuring the correct items have been received. Any discrepancies should be identified and resolved quickly.
Receipt information also needs to be accurately recorded so inventory data reflects what is actually available.
6. Invoice approval and payment
The supplier submits an invoice for the goods or services provided.
The organisation verifies that the invoice matches the agreed purchase and confirms that the goods or services have been received. Once the necessary checks and approvals have been completed, payment can be processed according to the agreed terms.
7. Record keeping and supplier performance review
The procurement process does not end when the invoice is paid.
Businesses should retain accurate records of orders, invoices, supplier agreements and other relevant documentation. This information supports financial reporting, audits and future procurement decisions.
Supplier performance should also be reviewed over time. Procurement teams can assess measures such as delivery reliability, lead-time performance, product quality and pricing to understand whether suppliers continue to meet expectations.
This creates a feedback loop. Supplier performance data can inform future purchasing and inventory planning decisions rather than each procurement cycle starting from scratch.
Common challenges in the procurement process
Even a well-defined procurement workflow can become inefficient when teams lack visibility, reliable data or consistent processes. Common challenges can affect everything from supplier relationships to inventory availability and working capital.
Rogue or dark spending
Rogue spending occurs when employees purchase goods or services outside approved procurement processes or suppliers.
This makes spending harder to track and can prevent organisations from taking advantage of negotiated supplier agreements. Clear purchasing policies, approval processes and better visibility can help bring more spending under control.
Manual data entry and errors
Procurement often involves information moving between spreadsheets, emails, ERP systems and supplier documents.
Manual re-entry increases the likelihood of incorrect quantities, duplicate orders and outdated information. It also takes time away from more valuable procurement activities.
Connecting systems and automating routine processes can reduce this administrative burden.
Supplier risk and unreliable lead times
A supplier may quote a standard lead time, but actual delivery performance can vary considerably.
If procurement decisions rely on outdated or overly optimistic lead times, orders may be placed too late to maintain the required stock levels.
Tracking actual supplier performance gives teams a more realistic view of how long replenishment takes and helps them account for variability when planning future orders.
Internal approval bottlenecks
Lengthy or unclear approval processes can delay purchases even when the requirement itself is straightforward.
These delays are particularly problematic when inventory is already approaching a critical level. Clear responsibilities and appropriate approval workflows help purchases move through the organisation without unnecessary waiting.
Poor visibility between procurement and inventory
Procurement teams need an accurate view of stock levels, incoming orders and future requirements.
When procurement and inventory planning operate separately, buyers may place orders without understanding what is already available or on the way. This can result in duplicate purchasing and excess stock.
Shared data helps purchasing decisions reflect the organisation’s actual inventory position.
Poor demand visibility
Procurement teams need to know not only what inventory the business currently holds, but what it is likely to need in the future. Without reliable demand forecasts, buyers may order too much, too little or too late.
Poor demand visibility can lead to excess stock, stockouts and unnecessary last-minute purchasing. Reliable forecasting gives procurement teams a clearer view of future requirements, helping them plan purchases earlier and align orders more closely with expected demand.
How automation supports better procurement decisions
Automation can make procurement more efficient, but it can support very different parts of the process.
General procurement workflow tools typically automate transactional tasks such as approvals, purchase order processing and invoice management. These systems help businesses move purchases through the procurement process efficiently once a requirement has been identified.
Inventory planning and replenishment automation happens earlier. It helps determine what needs to be ordered, how much is required and when the order should be placed.
For businesses managing inventory, this is a critical part of procurement. A smooth purchasing workflow cannot compensate for an order based on inaccurate demand assumptions, outdated lead times or poorly calculated stock requirements.
Inventory planning software can strengthen procurement decisions by bringing together:
- Demand forecasting: Predict future requirements using historical demand, trends, seasonality and other relevant information.
- Inventory positions: Account for current stock and incoming orders before recommending additional purchases.
- Safety stock: Maintain an appropriate buffer against uncertainty without simply increasing stock across the board.
- Supplier lead-time data: Factor in how long inventory takes to arrive and adjust plans as lead times change.
- Replenishment rules: Calculate when and how much to order based on demand and inventory requirements.
- Exception management: Highlight items that need planner attention while allowing routine replenishment decisions to be automated.
This creates a clearer connection between inventory planning and procurement. Instead of waiting for stock to run low and then deciding what to buy, teams can identify future requirements earlier and give suppliers better visibility into upcoming needs.
Better forward visibility can also support supplier negotiations. Purchase plans give procurement teams a clearer picture of expected volumes and timing, which can help them discuss pricing, delivery schedules and supplier capacity from a more informed position.
The result is not simply a faster procurement workflow. It is a better-informed one, with purchasing decisions based on what the business is likely to need rather than what has already happened.
How AGR supports smarter procurement planning
AGR strengthens the planning that happens before a purchase order is created. By connecting demand forecasts with inventory levels, supplier lead times and replenishment requirements, AGR helps teams make more informed purchasing decisions.
With AGR, businesses can:
- Generate SKU-level demand forecasts using statistical and AI-driven forecasting
- Optimise safety stock based on demand and supply uncertainty
- Use supplier and lead-time data to improve purchasing decisions
- Calculate replenishment requirements and recommended order quantities
- Automate routine ordering while directing planners towards exceptions that need attention
- Create forward-looking purchase plans that can support better supplier coordination
AGR works alongside your existing ERP, adding a dedicated planning and inventory optimisation layer to support the decisions that feed into the procurement process.
This helps procurement and inventory teams move away from reactive purchasing towards a more forward-looking approach based on expected demand and actual inventory requirements.
