Power Automate approval workflows: A guide to automating business approvals

Business approvals often rely on emails, spreadsheets, Teams messages, and manual follow-up. As approval volume grows, these processes can become difficult to track, slow down decisions, and create inconsistent handoffs between employees and departments.

Microsoft Power Automate can turn these manual approval processes into structured workflows that automatically route requests, collect decisions, and move work forward. This guide explains how Power Automate approval workflows work, the types available, when to use them, how to create them, and common examples across finance, sales, operations, and document management.

What is Power Automate?

Microsoft Power Automate is a workflow automation platform within Microsoft Power Platform. It enables organizations to automate tasks and processes that span different applications and services. Power Automate includes cloud flows for processes triggered automatically, manually, or on a schedule, as well as desktop flows for automating desktop and web tasks. For business approval processes, cloud flows are typically the most relevant.

Power Automate can connect Microsoft applications such as Dynamics 365, SharePoint, Teams, and Outlook with many other cloud services through prebuilt or custom connectors. A trigger starts the flow, such as the creation of a purchase request or document, and actions determine what Power Automate does next. Those actions can include sending notifications, updating records, creating tasks, transferring data, and requesting approvals.

What are Power Automate approval workflows?

Power Automate approval workflows are automated processes that route a request to one or more people for a decision and then continue the business process based on their response. They combine automation with human oversight, helping organizations create consistent approval processes for transactions, documents, requests, and other business decisions.

An approval workflow can begin when an employee submits a request, a document is uploaded, a record changes, or another defined event occurs. Power Automate can gather information from the connected application, send the request to the appropriate approver, capture the response, and take different actions based on the decision.

For example, a purchase request could automatically go to the requester’s manager and then move to finance when the amount exceeds a defined threshold. Once approved, Power Automate could update the request status, notify the employee, and start the next step in the purchasing process. This connects the approval directly to the broader workflow instead of relying on employees to track responses and move the process forward manually.

How do Power Automate approval workflows work?

Power Automate approval workflows work by connecting a business trigger, approval request, human decision, and automated next step into one process. While the details vary by use case, most approval workflows follow five core steps.

1. Trigger event: The workflow starts when a defined event occurs, such as a request being submitted, a document being uploaded, or a record being created or changed.
2. Gather information: Power Automate collects the relevant request details from connected applications so the approver has the information needed to make a decision.
3. Route for approval: The workflow sends the request to the appropriate manager, finance team, or other approver based on defined business rules.
4. Capture response: The approver reviews the request and submits a response, such as approve, reject, or another configured option.
5. Next action: Power Automate uses the response to continue the process automatically. It can update a record, notify users, create another approval, or start the next business step.

Benefits of Power Automate approval workflows

Power Automate approval workflows help organizations replace manual, inconsistent approval processes with structured automation. This can improve speed, visibility, and control while reducing the amount of follow-up required from employees.

• Faster approval cycles: Requests automatically reach the right decision-makers instead of waiting for employees to route emails or follow up manually.
• Less administrative work: Power Automate can handle routing, notifications, status updates, and follow-up actions that employees would otherwise complete themselves.
• More consistent processes: Approval rules are built into the workflow, helping requests follow the same process each time defined conditions are met.
• Better visibility: Approval requests, responses, comments, and outcomes can be tracked as part of the workflow instead of being scattered across emails and conversations.
• Stronger business controls: Organizations can require the appropriate authorization before purchases, expenses, discounts, documents, or other transactions move forward.
• Connected business processes: Approval decisions can trigger actions across Dynamics 365, SharePoint, Teams, Outlook, and other connected applications.
• Scalable approval rules: Workflows can route requests based on factors such as amount, department, request type, or other business data as processes become more complex.

The value of Power Automate approval workflows goes beyond digitizing approvals. They connect the decision to the broader business process so requests can move from submission to approval and completion with less manual intervention.

When should you use Power Automate approval workflows?

Power Automate approval workflows are a good fit when a business process requires human authorization before the next step can occur. They are especially useful when approvals happen often, involve multiple people or systems, or follow rules that can be clearly defined.

A strong candidate for automation is a process currently managed through email, spreadsheets, Teams messages, or manual follow-up. If employees spend time figuring out who should approve a request, checking its status, or updating another system after a decision, Power Automate can help streamline the process.

Organizations should consider approval automation when they need to:

• Route requests to specific people based on business rules
• Require authorization before transactions continue
• Standardize approval processes across teams or locations
• Reduce approvals managed through email or manual follow-up
• Coordinate multiple levels of approval
• Notify employees when a decision is made
• Update connected systems after approval
• Improve visibility into approval status and responses

Not every process needs an approval workflow. If an action can be completed safely using predefined rules without human judgment, a standard automated workflow may be more efficient. Approval workflows add the most value when a person genuinely needs to review, evaluate, or authorize a request.

Types of Power Automate approval workflows

Power Automate supports several approval structures for different business requirements. The right option depends on how many people need to review a request, whether approvals must happen in a specific order, and what type of response the process requires.

• Everyone must approve: Every assigned approver must approve the request before it can move forward. If one person rejects it, the approval can be completed as rejected.
• First to respond: The first assigned approver to submit a decision determines the outcome. This works well when several people are authorized to make the same decision and only one response is needed.
• Custom responses: Approvers can choose from options beyond Approve or Reject, such as Need more information or Request changes. This is useful when the decision is not strictly yes or no.
• Sequential approvals: The request moves through approvers in a defined order. Each approval can determine whether the request continues to the next person in the sequence.
• Parallel approvals: Multiple approval paths run at the same time, allowing different teams or stakeholders to review a request independently. In Power Automate, this is typically built using parallel branches rather than selected as a standalone approval type.

How to create a Power Automate approval workflow

Creating an effective Power Automate approval workflow starts with understanding the business process before building the flow. You need to define what triggers the approval, who should review it, what information they need, and what should happen after each possible response.

A typical Power Automate approval workflow can be created through the following steps:

1. Define the approval requirements. Identify what needs approval, who should review it, what information they need, and what should happen after each possible response.
2. Create the flow and choose a trigger. Define the event that begins the workflow, such as a submitted form, new SharePoint item, changed Dynamics 365 record, or uploaded document.
3. Connect the required applications. Add the connections Power Automate needs to retrieve information and perform actions across the systems involved in the process.
4. Add the approval action. For most standard approval workflows, use Start and wait for an approval, which creates the request and pauses the flow until the approval criteria are met. More advanced workflows can use Create an approval and Wait for an approval separately when other actions need to occur while the approval remains open.
5. Configure the approval. Select the appropriate approval type, assign the approvers, and provide the request details, links, attachments, or other information they need to make a decision.
6. Define what happens next. Add conditions and actions that determine what the workflow should do after an approval, rejection, custom response, or other outcome.
7. Test and monitor the workflow. Test each possible path, confirm that requests reach the correct approvers, and verify that notifications and downstream actions work as expected.

AI tools like Copilot can make this process easier by helping users create and modify cloud flows with natural language. You can describe the approval process you want to automate, and Copilot can suggest the trigger, actions, and flow structure needed to build it. Users can then continue working with Copilot to add steps or make changes, reducing the amount of manual configuration required while still keeping control over the final workflow.

Common Power Automate approval workflow examples

Power Automate approval workflows can support repeatable approval processes across finance, sales, operations, human resources, and other departments. The strongest use cases have a clear trigger, defined approval requirements, and a specific action that should happen after the decision.

Purchase order and purchasing approvals

Purchase approvals often depend on the amount being spent and who is responsible for the budget. An organization may require a manager to approve every purchase request, while purchases above a defined threshold also require finance or executive approval.

• Trigger: An employee submits a purchase request.
• Approval requirements: The employee’s manager must approve the request. Higher-value purchases are also routed to finance or another senior approver based on the amount.
• Next action: Power Automate updates the request status, notifies purchasing, and starts the next step in the purchasing process.

Rand Group has used Power Automate for this type of process in real-world Microsoft environments. For Petroplex Acidizing, our team configured Power Automate workflows for purchase order approvals and other operational processes as part of a broader Microsoft Dynamics 365 implementation.

Expense approvals

Expense approvals help organizations enforce spending policies before employee expenses are reimbursed or posted. Approval requirements may vary based on the expense amount, category, employee, or department.

• Trigger: An employee submits an expense report with the required details and supporting documents.
• Approval requirements: The employee’s manager reviews the expense, with additional finance approval required when the amount or expense type meets defined criteria.
• Next action: Power Automate records the decision, notifies the employee, and moves an approved expense to the next step in the reimbursement or accounting process.

Sales quote and discount approvals

Sales organizations may require approval when a quote includes discounts, pricing, or commercial terms outside standard guidelines. Different approval levels can be applied based on the size of the discount or value of the deal.

• Trigger: A sales quote or discount exceeds a defined threshold or falls outside standard pricing rules.
• Approval requirements: The request is routed to a sales manager, finance leader, or executive based on the discount percentage, deal value, or other defined criteria.
• Next action: Power Automate records the decision, updates the sales record, and notifies the sales representative so the opportunity can move forward.

Document approvals

Contracts, policies, proposals, marketing materials, and other documents may require review before they can be finalized or published. Some documents may need one approver, while others require several departments to review them in sequence or at the same time.

• Trigger: A document is uploaded, updated, or submitted for review in a connected application such as SharePoint.
• Approval requirements: The document is routed to the required reviewers based on its type, department, or other business rules.
• Next action: Power Automate records the responses, updates the document status, and notifies the appropriate users when the review is complete.

Power Automate approval workflow best practices

Effective Power Automate approval workflows start with clear business rules and a simple process for both requesters and approvers. The goal is to automate the right process, not add technology to an inefficient one.

• Start with the business process. Define the approval requirements, decision points, exceptions, and desired outcome before building the workflow.
• Keep approval chains simple. Require approval only from people who genuinely need to make a decision. Unnecessary approval levels can create delays.
• Use business rules for routing. Route requests dynamically based on factors such as department, amount, location, or manager instead of creating separate workflows for every scenario.
• Give approvers the right information. Include the details, documents, links, and context needed to make a decision without requiring users to search across multiple systems.
• Plan for exceptions. Define what should happen after rejections, missing information, unavailable approvers, and other situations that fall outside the standard approval path.
• Use Copilot, testing, and monitoring to improve the workflow. Copilot can help build and refine flows, but approval logic should always be reviewed and tested. After deployment, monitor flow runs, delays, and failures to identify opportunities for improvement.

Power Automate should not simply recreate every step of a manual approval process. Automation is an opportunity to remove unnecessary steps, improve controls, and create a process that is easier to manage as the business changes.
