Approval Workflow Software: Real-World Use Cases and Trends

Yoom Team
Yoom Team

Automation and AI are changing how businesses work. But even as AI takes on more tasks, human approval remains an important part of many business processes.
Approval workflow software helps businesses manage the processes in a structured way
, from collecting requests and checking information to routing them to the right approvers and carrying out the next steps. Some tools also use AI to check requests, identify missing information, and handle routine tasks before a request reaches a person for a final decision.

So, when do businesses rely on human judgment, and when can AI handle the work instead? How are companies combining AI and human review in their approval workflows? And what do real-world workflows reveal about the latest trends in approval automation?

In this article, we'll explore real-world approval workflow data from Yoom, examine how businesses use AI and human review together, and compare approval workflow software for different business needs.

Best Approval Workflow Software: 4 Tools to Consider

The best approval workflow software depends on how your business handles requests, which apps your team uses, and how much control you need over the approval process.

Some tools focus on simple approvals within Slack or Microsoft Teams. Others are designed for complex business processes or companies that rely heavily on Microsoft 365.

Here are four options to consider.

1.

Yoom

: Best for Approvals Across Multiple Business Apps

Yoom is a no-code workflow platform that connects business apps and helps teams manage work across different tools. Users can build workflows visually without writing code.

How it handles approvals

Yoom can start an approval workflow when someone submits a form or updates a record in a connected app.


For example, a workflow can extract the total amount from an invoice PDF, check the relevant information, and send an approval request to a manager through Slack, Microsoft Teams, or email.

Once the manager approves the request, Yoom can continue the workflow by updating Salesforce, sending a document for electronic signature, or recording the details in a spreadsheet.

Key features

  • Visual workflow builder that does not require coding
  • Connections between multiple business apps
  • Approval steps and rules for routing requests to different people
  • AI Workers that can help read documents and extract information
  • Automated actions after an approval or rejection


Best for:
Operations, Finance, and IT teams that want to connect approval processes with the other apps they use across the business.

Pricing: A free plan is available. Paid plans start at approximately $16 per month.

2.

Approveit

: Best for Simple Approvals in Slack and Microsoft Teams

Approveit is an approval management tool focused on helping teams handle requests through communication apps.


How it handles approvals

Teams can send internal requests to Slack, Microsoft Teams, or email and track their status. This makes it easier for managers to review requests without relying entirely on long email conversations.

Microsoft Power Automate

: Best for Businesses Using Microsoft 365

Microsoft Power Automate helps businesses connect apps and automate repetitive tasks. It works closely with Microsoft products, including SharePoint, Microsoft Teams, and Dynamics 365.

How it handles approvals

A business can create a workflow that sends a document stored in SharePoint or OneDrive to a manager for review. Managers can use Microsoft Teams to review and respond to supported approval requests.


After the decision, the workflow can update a record, notify the requester, or start another task.

Key features

  • Integrations with Microsoft 365 apps
  • Approval workflows through Microsoft Teams
  • Connections to SharePoint, OneDrive, and other business systems
  • Automated actions based on approval decisions

Best for: Organizations that already use Microsoft 365 and want to manage approvals within their existing software environment.

Pricing: A 30-day trial is available. Power Automate Premiumplans start at $15 per user per month.


What the Data Reveals: How Businesses Use Approval Workflows

We analyzed active approval workflows on Yoom to understand how businesses handle approval requests.

The data shows where requests begin, which departments use approval workflows most often, and how businesses notify managers when a decision is needed.

A typical automated approval workflow follows these steps:

  1. Receive a request: An employee submits a form or updates a record in a business app.
  2. Prepare the information: The system collects relevant details, such as invoice amounts or customer information.
  3. Ask for approval: The manager receives a notification in Slack, Microsoft Teams, or email.
  4. Record the decision: The manager approves or rejects the request.
  5. Complete the next step: The system updates a spreadsheet, notifies the requester, or starts another process.

This approach keeps people involved in important decisions while reducing the manual work needed to manage each request.


1. Where Do Approval Requests Start?

Approval requests don't always begin in large enterprise systems. Our analysis of more than 88,000 workflows shows that many start with everyday business tools, such as online forms, databases, and scheduled tasks.

Here are the most common starting points in the dataset.

  • Online Forms (32.7%)
    Employees submit requests through tools such as Google Forms, Typeform, or internal forms. These requests might include expense claims, time-off requests, and purchase orders. Once a form is submitted, the workflow can send the request to the appropriate manager automatically.
  • Scheduled Tasks (21.8%)
    Some approval workflows run at set times, such as every day or every week. For example, a workflow can collect unpaid invoices every Friday and send them to a manager for review.
  • Database and Status Changes (17.8%)
    A workflow can start when information changes in a database or CRM system. For example, when a sales opportunity reaches the contract negotiation stage, the system can notify the legal team that approval is needed.
  • Manual Requests (17.8%)
    Employees can also start a workflow themselves when they need approval for a specific situation.
  • Notifications from Other Business Apps (9.8% combined)
    Some workflows start when another app sends a notification that an event has occurred. For example, a change in one system can trigger an approval request in another.

These examples show that approval workflow software can work with the tools a business already uses, rather than requiring every request to start in a separate approval portal.


2. Which Departments Use Approval Workflows Most?

Some business decisions need more careful review than others. Financial transactions, employee information, and contracts often require approval before a business can take the next step.

Our analysis shows that Finance and HR account for 70% of the approval workflows in the dataset.

  • Finance, Accounting, and Invoicing (45%)
    Common examples include invoice approvals, expense reimbursements, purchase orders, and payment checks.
  • HR and Recruiting (25%)
    Common examples include job offer approvals, time-off requests, employee onboarding, and attendance corrections.
  • Sales and CRM (15%)
    Common examples include discount approvals, sales stage changes, and customer information updates.
  • Legal and Contracts (10%)
    Common examples include contract reviews, NDA approvals, and vendor agreement approvals.
  • General Administration and IT (5%)
    Common examples include hardware requests, software access requests, and internal document approvals.


Why Do Finance and HR Approval Workflows Matter?

Finance and HR teams often handle sensitive information and important business decisions. For example, Finance teams may need to check whether expenses follow company rules, while HR teams need to make sure employee requests meet internal policies.

These checks don't always have to be done by people. AI can also review requests by using a company's internal knowledge, such as expense policies, HR guidelines, and other internal rules.

The best approach depends on what needs to be checked and how much risk is involved.

  • Use AI for routine checks: AI can answer common questions about company policies, check requests against internal guidelines, and identify missing information.
  • Keep human review for decisions that require stricter control: For example, a company may want a manager to make the final decision on large expenses, sensitive HR requests, or cases where an incorrect decision could have serious consequences.


Both approaches can be useful, and they can also work together. An automated approval workflow can use AI to check a request first, then send it to a manager only when human review is required.

Even when a manager needs to approve a request manually, the rest of the process can still be automated. The workflow can collect the necessary information, identify the right approver, send a notification, and carry out the next steps once a decision is made.


This helps solve two common problems:
employees no longer have to wonder who they should contact for approval, and managers can review requests through familiar tools at a time that works for them, without having to search across different systems or respond immediately.

3. How Long Do Approval Workflows Take?

Based on Yoom's workflow data:

  • Average approval time: 1 hour and 1 minute
  • Median approval time: Approximately 1 second

These results suggest two common patterns: some managers approve requests as soon as they receive a notification, while others review requests between meetings or at a time that works for them.

Approval workflow software helps reduce the time spent finding the right approver, sharing information, and following up manually. Even when a manager needs more time to make a decision, the workflow can handle the steps before and after approval automatically.


4. Where Do Managers Receive Approval Requests?

A workflow needs to reach the person who can make the decision. If managers overlook notifications or have to open another system to review each request, the approval process can still be slow.

Our workflow data shows that more than 90% of active approval workflows send requests to real-time business chat tools, such as Slack and Microsoft Teams.

In addition, 37.8% of workflows include an email notification. Email can provide a record of the request or reach people who do not regularly use chat tools.

Whether managers approve requests through email or chat tools, they can review and approve them with a single click in tools they already use. This reduces the need to switch between systems and helps them focus on reviewing each request, potentially reducing the chance of overlooking important details.

When Should AI Handle a Task, and When Is Human Approval Needed?

AI can help process information in an approval workflow, but not every task should be handled by AI alone.

To understand how businesses divide work between AI and people, we analyzed the actual actions recorded in Yoom workflows.

The data reveals a clear pattern: AI is commonly used to extract, organize, and transform information, while people handle approval decisions, final checks, and situations that require individual judgment.

AI: Processing and Organizing Information

AI is used for tasks such as:

  • Extracting information from files and text
  • Cleaning up and transforming data
  • Correcting text extracted through OCR
  • Translating documents and summarizing long text

Human: Making Decisions and Checking Important Details

Human review is used for tasks such as:

  • Approving employee requests
  • Checking important details, such as addresses and phone numbers
  • Deciding whether a message should be sent
  • Reviewing inconsistent records and deciding how to correct them


AI is useful when a task involves processing large amounts of information or converting it into a consistent format. People are still important when a decision requires context, when an error could have serious consequences, or when someone needs to take responsibility for the outcome.


The Growing Trend of Combining AI and Human Review

The data also shows that workflows using AI often include additional steps, such as conditional routing and repeated actions. This allows businesses to combine AI processing with human approval in a single workflow.

For example, an automated approval workflow can use AI to check a request before sending it to a manager for final approval. If information is missing or something needs to be corrected, the workflow can send the request back to the applicant. If everything looks correct, it moves to the manager for a final decision.


Consider an expense approval workflow:

  1. Collect the request: An employee submits an expense claim and attaches a receipt.
  2. Check the information with AI: AI extracts the amount, date, and vendor from the receipt, then checks the details against the submitted form and company guidelines.
  3. Return requests that need corrections: If information is missing or the details do not match, the workflow sends the request back to the employee for correction.
  4. Request human approval: If the information passes the checks, the workflow sends the request to a manager, who decides whether to approve or reject it.
  5. Complete the next steps: Once approved, the workflow records the expense and notifies the employee.

In this approach, AI handles routine checks and identifies requests that need attention, while the manager focuses on the final approval decision. This can reduce manual checking and back-and-forth communication without removing human oversight.

The goal of approval workflow software is not to replace every human task with AI. It's to make the entire approval process more efficient by using AI for routine checks, involving people when their judgment is needed, and automating the steps in between.

■Overview
This AI worker automatically determines the appropriate approval route based on the request details and the rules you set. It automates the entire process—from sending approval requests and handing them off to the next person in charge to notifying requesters when requests are rejected and saving and recording the final outcome. This significantly reduces the effort required to manage internal approval rules.

■Preparation
To ensure that the AI worker can determine approval routes according to your company's rules, prepare a document that outlines your approval rules in advance, such as “Department manager approval is required for amounts of ¥100,000 or more.” You can create the document using tools you already use, such as Google Docs or Microsoft Word. Add the document to the AI worker’s “Skills” or provide it directly in the chat, and the AI worker will read and use the information in its processing.
In addition, set the people responsible for approvals as “Teammates” in advance so the AI worker can automatically send approval requests to the approvers it identifies.

■How to Set Up the AI Worker
Simply give instructions in the chat to automatically configure and update the AI worker to match your operations. First, customize the “Skills” and “Tools” so the AI worker can execute processes correctly.
  • What are “Skills”?
    They are the instructions the AI worker follows to perform tasks. For detailed setup instructions, see “[AI worker] How to Create Skills (formerly Manuals).”
  • What are “Tools”?
    These are the tools the AI worker uses to perform tasks. Simply tell the AI which tools your company uses regularly, and you can freely configure where data is retrieved from and where it is sent.
For more information about the basic AI worker settings, see “[AI worker] Basic Setup Guide.”

■Notes
  • The number of AI workers that can run simultaneously, the number of AI workers you can create, and the AI models available to you vary depending on your plan.
  • The apps and operations available within an AI worker are subject to the same usage limits as Workflow.
  • Please note that AI workers consume tasks during test runs just as they do during production runs. For details, see “[AI worker] How Task Execution Counts Are Calculated.”

■Overview
Each time laws are amended, confirming “Do any changes affect our internal work rules?” and “Which provisions should be changed, and how?” requires specialized knowledge and significant time. Missing any updates can also create operational risks, which may feel like a heavy burden.
This AI worker automatically compares legal changes with your company’s regulations and tells you exactly what to change, by when, and how. It eliminates the hassle of complex review processes and creates an environment where you can update your regulations smoothly.

■Who this AI worker is for
  • HR and labor management professionals who spend significant time comparing their company’s work rules and wage regulations against legal amendments
  • HR and General Affairs teams who want to carefully manage risks by preventing missed updates or overlooked changes and assessing the impact of each change
  • Professionals who want to organize the sections requiring updates and compile proposed revisions before consulting an expert

■How to configure the AI worker
Simply give instructions in chat, and the AI worker will automatically configure and update itself to match your company’s operations. First, customize the “Skills” and “Tools” so the AI worker can process tasks correctly.

■Overview
Compare and analyze attendance data across departments and locations. AI identifies and reports areas with sharp increases in overtime, uneven paid leave usage, and high risk of overwork. It calculates risk scores based on month-over-month and cross-location comparisons, then clearly highlights the departments and employee categories that require priority review. Even if your organization has not defined review criteria, you can proceed with analysis using provisional benchmarks based on general trends, helping you improve labor management and prevent missed actions.

Three Ways to Build an Approval Workflow Using Yoom

Building an approval workflow takes some initial effort. You need to decide what information to collect, who should review each request, what happens when a request is rejected, and which steps can be handled automatically. The more complex your process, the more planning and setup it may require.

However, you don't have to build everything from scratch. Yoom is an all-in-one business automation platform that connects the apps your team already uses and helps automate repetitive tasks across departments.


Yoom offers three ways to build workflows, depending on your needs and how much customization you want.


Option 1. Start with a Template

If you want to automate a common approval process quickly, start with a ready-made template. Choose one that matches your needs, then adjust it to fit your team's approval rules.

For example, you could use a template to collect expense requests, notify the right manager when a request is submitted, or update a business app once a request is approved.

Templates give you a starting point, so you don't have to plan and configure every step yourself. You may still need to adjust the workflow to match your approval rules and existing processes.

Option 2. Let AI Worker Help Build Your Workflow

If you know what you want to automate but aren't sure how to build it, describe your goal in natural language. Yoom's AI Worker can help you turn your idea into an automated workflow.


For example, you could describe a process that checks submitted expense information, returns requests with missing details to the applicant, and sends complete requests to a manager for final approval.

This approach can help you get started without having to figure out every technical detail on your own. You may still need to review the workflow and adjust it to match your company's approval rules.

Option 3. Build a Custom Workflow

If a template or AI-assisted setup doesn't fully meet your needs, you can build a custom workflow using Yoom's customization features.

Connect the apps you already use and configure each step to match your process. For example, you could collect a request through a form, check the submitted information, route it to different approvers based on the request type or amount, and notify the applicant once a decision has been made.

You can also combine app integrations with AI, OCR, and RPA to handle different types of work within the same workflow.

This option gives you more control over complex approval rules and processes that are specific to your business. However, it may require more time to design, configure, and test than starting with a template.

Start Small and Improve Your Workflow Over Time

Approval workflow automation isn't just about connecting apps. It also involves deciding how requests should move through your organization, which checks can be automated, and where human judgment is needed. Setting this up takes some initial effort, but a well-designed workflow can reduce repetitive work and make the approval process easier to manage over time.

You don't need to automate every step at once. Start with one recurring approval task, learn what works for your team, and expand from there.

With Yoom, you can start with a template, use AI Worker to help build a workflow, or create a custom process that fits your needs.
