SharePoint Purchase Request & Approval Workflow: Complete Guide for 2026

A SharePoint purchase approval workflow captures purchase requests and automatically routes them to the appropriate approvers based on rules such as purchase amount, department, budget, or other business requirements. A typical workflow follows this pattern: Submit request → Validate request → Determine approval path → Collect approvals → Notify requester → Authorize purchase → Retain the record Organizations can build a SharePoint purchase approval workflow using Microsoft 365 capabilities such as SharePoint and Power Automate, or use a dedicated SharePoint workflow platform for more complex forms, routing, dashboards, and business processes.

• A SharePoint purchase approval workflow routes purchase requests to the appropriate approvers.
• Approval rules can be based on purchase amount, department, budget, vendor, or other business requirements.
• Simple purchase approvals can often be handled with Microsoft 365’s built-in capabilities.
• Power Automate can add conditional routing, notifications, reminders, escalation, and integrations.
• A SharePoint workflow platform can provide reusable forms, workflow logic, dashboards, and approval processes for organizations managing multiple business workflows.
• A complete SharePoint procurement workflow can extend beyond approval to include purchase orders, receiving, invoice matching, and other purchasing activities.
• The workflow should maintain an audit trail showing what was requested, who approved it, when decisions were made, and what happened afterward.

What Is a SharePoint Purchase Request Workflow?

A SharePoint purchase request workflow is an automated process for collecting, reviewing, approving, and tracking requests to purchase goods or services. Instead of sending a purchase request through email or a series of manual forms, employees submit the request through a structured form. The workflow determines which approvals are required and routes the request accordingly. For example, a company might configure its workflow so that:

• Purchases under $500 require department manager approval.
• Purchases from $500 to $5,000 require manager and finance approval.
• Purchases from $5,000 to $25,000 require manager, finance, and director approval.
• Larger purchases require additional executive approval.

These thresholds are only an example. Each organization should establish its own approval rules based on its budgets, internal controls, delegation-of-authority policies, and regulatory requirements.

The Standard Purchase Request and Approval Process

Although purchasing processes vary between organizations, a typical SharePoint purchase approval workflow includes these steps:

1. Request submission: An employee submits information about the item or service, vendor, estimated cost, business justification, and other required details.
2. Request validation: The workflow checks that required information has been provided.
3. Rules-based routing: The workflow determines the required approval path based on factors such as cost, department, budget, or purchase type.
4. Manager approval: The appropriate manager reviews the request.
5. Finance or additional approval: Higher-value or specialized purchases may require additional approvals.
6. Approval or rejection: The requester is notified of the decision.
7. Purchase authorization: Approved requests move to the purchasing or ordering process.
8. Reconciliation and closeout: The organization records the purchase, invoice, payment, or other final information needed to close the request.

The important part is that the requester does not have to determine which approvals are required. The workflow applies the organization’s rules automatically.

How to Build a SharePoint Purchase Approval Workflow

1. Create the Purchase Request Form

Start by defining the information employees need to provide. A purchase request form might include:

• Requester
• Department
• Item or service
• Vendor
• Estimated cost
• Business justification
• Cost center
• Required-by date
• Budget information
• Supporting documents or quotes
• Additional notes

Only collect information that is actually needed for the decision. A form that asks for unnecessary information can make the purchasing process harder to use.

2. Store Purchase Requests in SharePoint

A SharePoint List can provide a structured location for storing purchase requests and their status. Common fields include:

• Request ID
• Requester
• Department
• Vendor
• Amount
• Status
• Current approver
• Approval level
• Submission date
• Approval date
• Rejection reason
• Purchase order number
• Completion date

Keeping the request and its status in a structured system also makes it easier to report on pending and completed purchases.

3. Define the Approval Rules

The workflow should determine the approval path from defined business rules. Rules can be based on:

• Dollar amount
• Department
• Cost center
• Vendor
• Purchase category
• Budget
• Type of expense
• Contract requirements

For example, a $300 office supply purchase may require only a manager’s approval, while a $15,000 software purchase could require manager, finance, and director approval.

4. Route the Request to the Correct Approvers

Once the workflow determines the required path, it sends the request to the appropriate person or group. Approval can happen sequentially or in parallel. Sequential approval means each approval happens in a defined order. For example: Manager → Finance → Director Parallel approval means multiple approvers can review the request at the same time when their decisions do not depend on one another. The appropriate approach depends on the organization’s purchasing policies.

5. Add Reminders and Escalation

A workflow should account for what happens when an approver does not respond. Possible actions include:

• Sending a reminder after a defined period
• Sending additional reminders
• Escalating the request to another person
• Reassigning an approval
• Notifying a manager when an approval remains pending

These rules help prevent approved purchases from getting stuck in someone’s inbox.

6. Notify the Requester

The requester should be able to see what is happening without emailing the purchasing team for an update. Notifications can communicate:

• Request received
• Approval required
• Request approved
• Request rejected
• Additional information required
• Purchase completed

For organizations using Microsoft Teams, approval and status notifications can also be incorporated into Teams-based processes.

7. Track the Request and Report on Activity

A useful purchase approval workflow should provide visibility into the process. Finance or purchasing teams may want to see:

• Requests awaiting approval
• Requests by department
• Requests by dollar amount
• Average approval time
• Approved versus rejected requests
• Purchases by vendor
• Requests that have been escalated
• Completed purchases

Reporting requirements should be considered when designing the workflow rather than added as an afterthought.

8. Maintain an Audit Trail

The workflow should retain a record of important events, including:

• Who submitted the request
• What was requested
• The requested amount
• Who approved or rejected it
• When each decision occurred
• Any comments or rejection reasons
• Changes to the request
• The final outcome

An audit trail can make it easier to answer questions about how a purchase was authorized and when decisions were made.

Example: $8,000 Software Purchase

Consider an employee requesting an $8,000 annual software subscription. A SharePoint purchase approval workflow could handle the request like this:

1. The employee submits the purchase request form.
2. The request is stored in SharePoint.
3. The workflow checks the purchase amount and department.
4. Because the purchase exceeds the organization’s manager-only threshold, the request is routed to the department manager.
5. After manager approval, the request is routed to finance.
6. A director provides the additional approval required for purchases above the defined threshold.
7. The requester receives an approval notification.
8. Purchasing creates the purchase order.
9. The completed request retains the approval history for future reference.

The exact approval path should be based on the organization’s own purchasing policies.

Three Ways to Build a SharePoint Purchase Approval Workflow

Organizations generally have three approaches to creating a purchase approval workflow around SharePoint and Microsoft 365.

Option 1: SharePoint and Microsoft 365 Approval Capabilities

For relatively simple processes, organizations can use SharePoint or Microsoft Lists together with Microsoft 365 approval capabilities. This approach can work well when the process has:

• A straightforward request form
• One or a small number of approval steps
• Limited routing requirements
• Basic status tracking
• Few exceptions

As the process becomes more complex, organizations may need additional automation and customization.

Option 2: SharePoint and Power Automate

Power Automate can extend SharePoint with automated approval workflows. It can be used for:

• Conditional routing
• Multi-level approvals
• Notifications
• Reminders
• Escalations
• Teams integration
• Updating SharePoint records
• Connecting the process with other systems

Power Automate is particularly useful when the organization needs workflow logic that goes beyond a basic approval process. More complex implementations can require conditions, expressions, branching, error handling, custom connectors, or additional Microsoft Power Platform components. The ongoing maintenance requirements should be considered when designing the workflow.

Option 3: A SharePoint Workflow Platform

A dedicated workflow platform built for SharePoint can provide forms, workflow logic, approvals, dashboards, and other capabilities within a common environment. This approach can make sense for organizations that:

• Need multiple business workflows
• Have complex approval rules
• Want reusable workflow components
• Need sophisticated forms and dashboards
• Want business analysts to manage workflows without building individual automation flows
• Are replacing legacy forms or workflow applications

The best approach depends on the complexity of the process, the organization’s technical resources, and how many workflows it expects to maintain.

SharePoint vs. Power Automate for Purchase Approval Workflows

SharePoint and Power Automate are often used together rather than as completely separate alternatives.

The goal is not to choose a technology based on features alone. Consider the complexity of the purchasing process, the number of workflows you need to support, who will maintain them, and how much customization is required.

Purchase Request vs. Purchase Order

A purchase request is an internal request asking for permission to purchase a good or service. A purchase order (PO) is a formal document used to authorize an order with a supplier. They are related but serve different purposes. A typical process might look like: Purchase request → Internal approval → Purchase order → Supplier fulfillment → Receipt → Invoice matching → Payment A SharePoint purchase approval workflow can handle the request and approval portion of this process. A broader procurement workflow can extend further into purchasing, receiving, invoice processing, and reconciliation.

What Is a SharePoint Procurement Workflow?

A SharePoint procurement workflow automates one or more processes involved in sourcing and purchasing goods or services using SharePoint and related Microsoft technologies. Procurement is broader than purchase approval. Depending on the organization, procurement can include:

• Purchase requisitions
• Supplier selection
• Vendor management
• Purchase approvals
• Purchase orders
• Receiving
• Invoice matching
• Payment
• Supplier records
• Contract-related processes

A purchase approval workflow can therefore be one component of a larger SharePoint procurement workflow. For organizations that manage multiple purchasing processes, using a common workflow environment can provide more consistent forms, routing rules, permissions, reporting, and records.

Common Mistakes to Avoid

Making Every Purchase Follow the Same Approval Path A $100 office supply purchase and a $50,000 capital purchase may have very different approval requirements. Use rules to route purchases based on amount, department, category, or other relevant criteria. Creating Too Many Approval Steps Every additional approval introduces another point where the request can wait. Only require approvals that serve a legitimate business, financial, compliance, or operational purpose. Keeping Approval Rules Outside the Workflow If employees need to consult a separate document or ask someone which approvals are required, the process is still partially manual. Where appropriate, put approval thresholds and routing rules directly into the workflow. Forgetting Reminders and Escalation An automated workflow can still become a bottleneck if requests simply sit with an approver. Define what should happen when an approval remains pending. Giving Finance No Visibility Finance and purchasing teams should be able to identify pending, approved, rejected, and completed requests without searching through email. Ending the Workflow at Approval Approval is not necessarily the end of the purchasing process. Depending on the organization, the workflow may also need to track purchase orders, receipts, invoices, or other completion information. Trying to Automate Everything at Once A practical approach is to start with a well-defined purchasing process and expand it after the core workflow is working reliably.

Example Purchase Approval Thresholds

The following is an illustrative example, not a recommended purchasing policy:

Actual thresholds should be determined by each organization’s purchasing policies, budget structure, delegation-of-authority rules, and regulatory requirements. The important part is not the specific dollar amounts. It is that the approval rules are defined clearly enough for the workflow to apply them consistently.

When Does a SharePoint Workflow Platform Make Sense?

Organizations often start with SharePoint and Power Automate because those technologies are already part of Microsoft 365. As the number and complexity of workflows grow, however, maintaining forms, routing logic, permissions, notifications, dashboards, and individual automation flows can become an ongoing development and administration task. A SharePoint workflow platform is another approach. Instead of creating each business process independently, organizations can use a common environment for:

• Forms
• Workflow logic
• Approvals
• Notifications
• Escalations
• Dashboards
• Permissions
• Business process records

This can be particularly useful when purchase approvals are only one of several business processes the organization wants to automate.

Frequently Asked Questions

Can you build a SharePoint purchase approval workflow without Power Automate?

Yes. Simple purchase approval processes can use SharePoint and Microsoft 365 approval capabilities without Power Automate. Organizations with more complex routing, notifications, escalation, and integration requirements can also use a dedicated SharePoint workflow platform. The right approach depends on the complexity of the workflow and how many business processes the organization needs to automate.

Can SharePoint route purchase requests based on dollar amount?

Yes. A purchase workflow can use the requested amount as a routing condition. For example, a workflow might send purchases below a defined threshold to a department manager while routing higher-value purchases through additional finance or executive approvals.

Can SharePoint send purchase approval notifications in Microsoft Teams?

Yes. SharePoint-based purchasing processes can be connected with Microsoft Teams to provide approval and status notifications. Power Automate can also be used to automate Teams notifications as part of a SharePoint workflow.

Can SharePoint handle multiple approval levels?

Yes. Multi-level approval processes can be implemented with SharePoint and Microsoft automation technologies. For example, a request might move from a department manager to finance and then to a director based on the purchase amount.

What information should a purchase request form include?

A purchase request form commonly includes the requester, department, item or service, vendor, estimated cost, business justification, required-by date, cost center, budget information, and supporting documentation. The exact fields should reflect the organization’s purchasing policies and approval requirements.

What is the difference between a purchase request and a purchase order?

A purchase request is an internal request for permission to make a purchase. A purchase order is a formal document authorizing an order with a supplier. A purchase request can therefore be approved before a purchase order is created.

Can Power Automate create a purchase approval workflow in SharePoint?

Yes. Power Automate can automate approval workflows using SharePoint data. A flow can evaluate request information, route the request to the appropriate approvers, send notifications, update the SharePoint record, and perform additional actions after approval.

What is a SharePoint procurement workflow?

A SharePoint procurement workflow is an automated process that supports one or more procurement activities using SharePoint and related Microsoft technologies. It can include purchase requests, approvals, purchase orders, vendor processes, receiving, invoice matching, and other purchasing activities.

The Bottom Line

A SharePoint purchase approval workflow gives organizations a structured way to collect purchase requests, apply approval rules, route requests to the right people, and maintain a record of decisions. Simple processes may be handled with SharePoint and Microsoft 365 capabilities. Power Automate can add conditional routing, notifications, reminders, escalation, and integrations. A dedicated SharePoint workflow platform can provide a broader environment for organizations managing complex or multiple business workflows. The most effective workflow is not necessarily the one with the most automation. It is the one that applies the organization’s purchasing rules consistently, gives employees visibility into their requests, gives finance the information it needs, and keeps the process easy to maintain.
