Business process automation with Microsoft Power Automate
1. Purchase order and invoice approval
A purchase request can trigger an approval workflow based on its value, department or cost centre. A request above £5,000, for example, can be routed to a department manager and then to finance.
If nobody responds within 48 hours, the workflow can send a reminder or escalate the request. Once approved, the information can be recorded in the finance system and the requester can receive a confirmation.
2. Employee onboarding
A new employee record in an HR system can trigger an onboarding checklist. Power Automate can notify the hiring manager, create tasks for IT, send training information and track whether the required steps have been completed.
The process can also send reminders when an account, device or access request is still pending. This gives HR and IT a shared view of progress without relying on separate spreadsheets.
3. Expense report routing
Expense reports can be sent to the right approver according to the employee's department, cost centre or spending limit. Receipts can be stored in SharePoint, while the approval status is recorded in the finance system.
Power Automate can also flag missing information, notify employees about rejected claims and send approved expenses to the next stage of processing.
4. Contract renewal reminders
A recurring task can check a SharePoint list, CRM or contract management system for agreements approaching their renewal date. Procurement can receive notifications 60, 30 and 7 days before a contract expires.
The workflow can also assign a review task to the relevant owner and record the outcome. This helps teams review terms before an agreement renews automatically.
Companies that need to review how business applications, workflows and system dependencies fit together can work with software architecture consulting before expanding their automation programme.
Workflow automation for approvals, SharePoint and files
Many Power Automate use cases involve Microsoft 365 tools. The main benefit comes from connecting the tools around a defined business process, rather than adding isolated flows without clear ownership.
5. SharePoint document approval and metadata tagging
When a document is added to a SharePoint library, Power Automate can start an approval workflow. It can send the file to the right reviewer, record the decision and notify the author.
The workflow can also add metadata such as department, document type, confidentiality level or retention category. This makes the document easier to search and supports consistent records management.
6. Service-level agreement notifications
A support ticket that approaches its response or resolution deadline can trigger a notification. Power Automate can alert the ticket owner, post a message in Microsoft Teams or notify a service manager when an SLA breach becomes likely.
These notifications are useful when teams already have a ticketing system but need a clearer escalation process. The workflow should use defined thresholds, so users receive alerts that require action rather than constant noise.
7. Email-to-task conversion
An email flagged in Outlook can automatically create a task in Planner, Microsoft To Do or another work-management system. The task can include the sender, subject, due date and a link to the original message.
This workflow helps teams track requests that would otherwise remain in personal inboxes. It works particularly well for internal support, procurement requests and administrative tasks.
8. File automation and retention
Power Automate can monitor files stored in SharePoint or OneDrive and take action when they meet defined conditions. A file may be renamed, moved to an archive library or assigned a retention label after a specific period.
The workflow can also notify an owner when a document is due for review. Clear rules are needed to prevent important files from being moved or deleted by mistake.
Data synchronization and recurring tasks
Power Automate can transfer information between systems and perform actions on a schedule. These use cases require more attention to data ownership, error handling and duplicate records.
9. Data synchronization between systems
A new lead captured in a marketing platform can be sent to a CRM as soon as the required fields are complete. A new customer record can also trigger updates in a finance, support or customer-success system.
The flow should define which system owns each field and what happens when the same record already exists. It should also log failed updates so that teams can investigate missing or conflicting information.
10. Cross-application approval chains
Some requests need several departments to review the same information. A supplier request, budget change or system-access request can move through Microsoft Teams for discussion, Outlook for formal approval and a business application for the final record.
The requester receives status updates while each approver sees the information relevant to their decision. This avoids copying the same data manually between applications.
At this stage, the workflow crosses several systems and may affect customer data, finance records or access permissions. Mantu's software architecture and delivery consulting can help define the right boundaries, ownership and review process before the automation is released.
What to check before creating a Power Automate flow
A simple flow can often be created by a business user. Cross-system or customer-facing automation needs more preparation.
Before building a workflow, define:
The business problem it solves.
The trigger that starts the flow.
The systems and data it can access.
The person responsible for the process.
The expected result and completion time.
The action required when a step fails.
The review date for the flow.
Permissions also need attention. A flow connected to a personal account may stop working when that person changes role or leaves the organization. Shared service accounts, documented ownership and controlled access are safer choices for important processes.
Testing should cover normal cases, missing information, duplicate records, rejected approvals and system errors. A flow that works with one example may still fail when a field is empty or an external system is unavailable.
When Power Automate needs an architecture review
Power Automate is well suited to local process improvements, recurring notifications and simple connections between business tools. Risk increases when a flow becomes responsible for a customer-facing process, synchronizes several systems or handles sensitive information.
Warning signs include:
Several flows performing similar tasks.
No clear owner for a business-critical flow.
Personal credentials used for shared processes.
Data copied between systems without validation.
No record of failed runs or manual corrections.
A workflow that has grown through repeated patches.
Changes in one application regularly breaking another flow.
A flow that synchronizes CRM leads with an ERP system, for example, crosses system boundaries and depends on data structures that can change. It should be reviewed as part of the wider application architecture rather than managed as a small personal automation.
Mantu's software architecture consulting team can help assess these dependencies, define delivery principles and connect automation decisions with the broader architecture roadmap.
Building a controlled automation programme
Power Automate works best when teams agree on a few operating rules before the number of flows grows. Classify flows by business impact, assign an owner to each shared process and keep a record of the systems and permissions involved.
A useful model separates:
Flow category | Typical example | Suggested ownership |
|---|---|---|
Personal productivity | Email-to-task conversion | Individual user |
Departmental process | Expense approval | Team manager |
Cross-system process | CRM to ERP synchronization | IT or architecture team |
Customer-facing process | Account notifications | Controlled delivery team |
The aim is to give teams room to automate while applying more control to flows that affect several systems or business units.
Power Automate use cases deliver the most value when each flow has a clear purpose, a responsible owner and a defined response when something goes wrong. With those conditions in place, workflow automation can reduce manual work without creating a second layer of undocumented processes.
