In a multi-level approval workflow, a request moves through a defined sequence of two or more approval stages. Different approvers can be involved depending on factors such as department, request type, value, location, risk level, or organizational role.
Multi-stage approvals, tiered approvals, sequential approvals, or approval chains. A software access request, for example, might first require approval from the employee’s manager, then the application owner, and finally IT or Security before access is provisioned.
What is a multi-level approval process?
A multi-level approval process defines several checkpoints that must be completed before an action is authorized.
A simple workflow might look like this:
Request submitted → Manager approval → Department approval → Finance approval → Final action
However, multi-level approval workflows do not always have to follow the same path.
More advanced processes can use conditional routing. For example:
- Purchases below $1,000 require manager approval only.
- Purchases between $1,000 and $10,000 require manager and Finance approval.
- Purchases above $10,000 also require approval from a department head or executive.
- Access to standard applications may require one approval, while access to sensitive systems requires Security approval as well.
This makes multi-level approval particularly useful for organizations where different requests carry different levels of cost, risk, or responsibility.
Why are multi-level approvals important?
As organizations grow, relying on informal approvals through email, chat, or verbal confirmation becomes increasingly difficult to manage.
Multi-level approvals provide a structured way to make sure the right people are involved before important actions are taken.
Stronger governance
Approval stages establish clear decision-making responsibilities. Employees know who needs to approve a request, while administrators can verify that the required authorization took place.
Better risk management
Sensitive or high-impact requests can be reviewed by multiple stakeholders before they are executed.
For example, giving an employee access to confidential financial data may require approval from their manager, the data owner, and IT Security.
Improved compliance and auditability
Many business processes require organizations to demonstrate who approved an action and when.
A structured approval process creates a traceable record of requests, decisions, comments, timestamps, and resulting actions.
Better control over spending
Multi-level approvals are commonly used to prevent purchases or expenses from being authorized without the appropriate level of financial oversight.
Reduced dependence on individual employees
When approval logic is formally defined, organizations are less dependent on employees remembering who should approve what.
Common multi-level approval use cases
Multi-level approvals can be used anywhere a business decision requires authorization from several stakeholders.
Access requests
An employee requests access to an application, Google Group, Shared Drive, folder, system, or dataset. For IT teams handling this at scale, see IT access request approvals.
The approval chain might include:
Employee → Manager → Resource owner → IT or Security
Once all required approvals are completed, access can be provisioned.
Purchase requests
Employees submit requests for software, equipment, services, or other business purchases.
Approval levels can change based on the purchase amount.
For example:
Requester → Manager → Budget owner → Finance → Executive approval
Expense approvals
Expense claims may require approval from a manager before being reviewed by Finance.
Higher-value expenses can automatically require additional approval.
Employee onboarding
Hiring or onboarding processes can require approval from several teams before accounts, software licenses, devices, or system permissions are created.
Leave requests
Leave may require approval from an employee’s manager and, depending on the organization, HR or another department.
Additional approval levels can be triggered for extended leave or specific types of absence.
Contract approvals
Contracts may need to be reviewed by the business owner, Finance, Legal, Procurement, or senior management before they can be signed.
Document approvals
Policies, proposals, reports, marketing materials, financial documents, or other business content may need to pass through several reviewers before publication or distribution.
Vendor approvals
New vendors may require approval from Procurement, Finance, Security, Legal, and the relevant business owner.
IT change requests
Infrastructure changes, application changes, administrative permissions, or security configurations may need approval from system owners and IT leadership before implementation.

Operations
Operations teams often manage processes that cross several departments, making multi-level approvals particularly useful for procurement, facilities requests, vendor management, operational changes, and internal service requests.
What are the challenges of multi-level approval processes?
Adding more approval stages can improve control, but it can also introduce operational friction if the process is managed manually.
Approval bottlenecks
A request may remain unresolved because one approver has not responded.
When several approvals are required, a delay at any stage can hold up the entire process.
Approvers do not know when action is required
Approval requests can easily disappear inside crowded email inboxes or chat channels.
Requesters may then need to manually remind approvers.
Complex routing rules
The correct approval path may depend on:
- Department
- Request type
- Cost
- Location
- Employee role
- Resource owner
- Risk level
- Business unit
Managing these rules manually quickly becomes difficult.
Approver availability
An approver may be on leave, unavailable, or no longer responsible for the relevant process.
Without delegation or escalation rules, requests can become stuck.
Too many unnecessary approvals
Poorly designed approval chains sometimes send every request through the same number of stages, even when additional approval provides little value.
This creates unnecessary administrative work.
Limited visibility
Requesters may not know whether their request is waiting for a manager, Finance, IT, or another stakeholder.
Administrators may also struggle to identify where requests are being delayed.
Inconsistent processes
Different employees may follow different approval routes for the same type of request.
This can lead to inconsistent decision-making and weak governance.
Missing audit trails
Approvals conducted through separate emails, messages, spreadsheets, and verbal conversations can be difficult to reconstruct later.
Changes made while approval is in progress
This is especially risky in document approval workflows. If the original document remains editable while people are reviewing it, the content can change after one or more approvers have already approved it. Different approvers may then be reviewing different versions, and the final document may no longer match what was actually approved.
To avoid this, the document should be locked for editing during the approval process or the workflow should create a fixed version or snapshot that becomes the official version under review.
Manual work after approval
Receiving approval is often only one part of the process.
Someone may still need to manually create an account, update a spreadsheet, change permissions, generate a document, send a notification, or update another system.
How automation helps manage multi-level approvals
Approval workflow software allows organizations to define the entire approval process in advance and automatically coordinate each stage.
Instead of manually forwarding requests between stakeholders, the workflow determines who should approve the request, sends the approval request, records the response, and decides what should happen next.
Automatically route requests to the right approver
Approval workflows can determine the appropriate approver dynamically based on information contained in the request.
For example, the workflow could identify:
- The requester’s manager
- The relevant department head
- The owner of a Google Group
- The owner of a Shared Drive
- A Finance approver based on purchase value
- A Security approver for sensitive access
This avoids maintaining a single static approval chain for every request.
Create conditional approval paths
Not every request needs the same level of scrutiny.
Automation allows approval stages to be added only when predefined conditions are met.
For example:
If software cost < $1,000 → Manager approval
If software cost ≥ $1,000 → Manager + Finance approval
If software cost ≥ $10,000 → Manager + Finance + Executive approval
Send automated reminders
If an approver does not respond within a defined period, the workflow can automatically send reminders instead of relying on the requester to follow up.
Escalate overdue approvals
Requests can be escalated to another person if the original approver does not respond within a specified timeframe.
Support approval delegation
Approval workflows can route requests to alternative approvers when the primary approver is unavailable.
Run approvals sequentially or in parallel
Some processes require one approval before the next person can review the request.
Others can request approval from several stakeholders simultaneously.
Automation can support both models.
For example:
Sequential:
Manager → Finance → Security
Parallel:
Manager + Application owner + Security
The workflow proceeds once the required approval conditions have been met.
Keep requesters informed
Automated notifications can tell requesters when:
- Their request has been received
- An approval has been granted
- Additional information is required
- A request has been rejected
- The process has been completed
Maintain an approval audit trail
Automated approval workflows can record:
- Who submitted the request
- Who was asked to approve it
- When the approval request was sent
- Approval or rejection decisions
- Comments
- Timestamps
- Actions performed after approval
This creates a much clearer record than approvals spread across email threads and chat messages.
Automate what happens after approval
One of the biggest advantages of approval automation is that the process does not have to stop once approval is granted.
The same workflow can continue and perform the required business action.
For example, after an access request is approved, an automated workflow could:
- Add the employee to the required Google Group.
- Grant access to a Shared Drive.
- Update an internal tracking system.
- Notify the requester.
- Record the completed action for audit purposes.
This turns an approval workflow into an end-to-end business process rather than simply a digital approval form.
Sequential vs parallel multi-level approvals
There are two common ways to structure multi-level approval workflows.
Sequential approval
Approvers review the request one after another.
For example:
Manager → Finance → Department Head
The second approval request is only sent after the first approver has approved the request.
Sequential approval is useful when later approvers should only review requests that have already passed earlier checks.
Parallel approval
Several approval requests are sent at the same time.
For example:
IT + Security + Application Owner
The workflow waits until the required approvers have responded.
Parallel approvals can significantly reduce processing time when approvers do not depend on each other’s decisions.
Many business processes combine both approaches.
For example:
Manager approval → IT + Security approval in parallel → Provision access
How to design an effective multi-level approval workflow
A good approval workflow should provide appropriate oversight without adding unnecessary friction.
Before building the process, define:
- What triggers the approval workflow?
- Which requests require approval?
- Who should approve each type of request?
- Which approvals should be sequential?
- Which approvals can happen in parallel?
- What conditions require additional approval levels?
- How long should an approver have to respond?
- What happens if an approver does not respond?
- Who should receive escalated requests?
- What happens when a request is rejected?
- What should happen automatically after final approval?
- What information needs to be retained for auditing?
The objective should not be to add as many approval stages as possible. It should be to involve the right decision-makers while keeping the process efficient.
Multi-level approval workflow example
Consider an employee requesting access to a sensitive application.
Step 1: Request
The employee submits an access request containing the application, requested role, business justification, and duration of access.
Step 2: Manager approval
The employee’s manager confirms that the access is required for the employee’s role.
Step 3: Application owner approval
The application owner checks whether the requested permission level is appropriate.
Step 4: Security approval
If the application contains sensitive information, the workflow automatically adds an additional Security approval stage.
Step 5: Provisioning
Once all required approvals are completed, the workflow grants the appropriate access.
Step 6: Notification and audit
The employee is notified, and the approval decisions and provisioning actions are recorded.
Without automation, each of these steps may require separate emails, reminders, administrative actions, and manual record keeping.
With workflow automation, they can operate as one connected process.
Multi-level approvals with Zenphi
Zenphi lets organizations build approval workflows that cover the entire process — from how a request enters the workflow, to who needs to approve it, what happens when an approval expires, and what business action should happen after the final decision.
An approval workflow can start from a Google Form, Jotform, Typeform, an internal portal, or another business process. It can even start directly in Google Chat when a workflow is converted into an enterprise AI agent for Google Chat using Zenphi AI Studio. That gives employees a conversational way to submit requests without introducing another standalone interface.
The approval path does not have to be fixed. Zenphi can evaluate information such as the requester’s department, role, manager, location, requested resource, purchase amount, risk level, or other workflow data and add an extra approval loop only when it is required.
For example, a standard software request may require manager approval, while a request involving sensitive data can automatically add the application owner and Security before the workflow continues.
Not every approval ends with an explicit Approve or Reject response. An approver may simply fail to respond before the expiry date. Zenphi can define what should happen next instead of leaving the request stuck indefinitely.
The workflow can send reminders, route the request to a backup approver, escalate it to a manager or process owner, create a follow-up task, or close the request according to your policy. The escalation path becomes part of the workflow logic rather than something the requester has to manage manually.
Approval does not have to be the end of the workflow. Once the required decision is reached, Zenphi can take action in Google Workspace or external systems automatically.
Depending on the process, the workflow can provision access, update records, create an invoice, process a payment, create and send a purchase order, onboard or offboard an employee, change Google Workspace permissions, generate documents, notify stakeholders, or trigger another connected business process.
This is what turns approval workflow software into more than a digital approval form: the request, approval logic, exception handling, audit trail, and downstream action can operate as one connected workflow.
