What is OneList?
OneList is approval management software that brings workflow tasks from SAP and other enterprise systems into a single list that approvers can act on from web, mobile, Outlook or email, and sends each decision back to the system it came from.
What OneList adds
- Every approval task from every connected system, in one place
- The context to decide, alongside each request
- Approval on web, mobile, Outlook, Teams, email and more
What stays in your source systems
- Workflow engines and business rules
- Your delegation of authority (DoA) matrix
- SAP authorizations and the system of record
Approvals stall when they’re spread across SAP and other systems
Approvals stall when every business system sends its own requests, so decision makers switch between systems, hunt through email, and approve without the context they need.
Your approval workflows and delegation of authority (DoA) matrix already live in systems like SAP, ServiceNow, Salesforce and Coupa. What’s missing is one place where approvers see every task waiting on them, with the context to decide.
When the details sit in different systems, some approvers hold the request and others approve without the full picture.

What does a stalled approval cost companies?
Requests left waiting slow the organization down, and requests approved without the full picture create risk.
Operations stop
Late replacement of critical equipment can stop operations.
Sales are lost
A delayed discount approval can lose a sale.
Candidates walk
A slow hiring approval can lose the candidate.
Spend slips through
Approving without the budget or documents in view can commit unplanned spend and create audit risk.
How OneList brings approvals from every system into a single list
OneList connects to each source system through an adapter, shows every open approval task in one place, and sends each decision back to the system it came from.

Tasks sync from your source systems
Adapters bring each task into OneList with its request details, budget, approval history and documents.
Approvers act from anywhere
OneList is available as a web app, native iOS and Android apps, Microsoft Outlook and Teams add-ins, a browser extension, a Windows desktop notifier, AI agents via the OneList MCP server and email. Mobile approvers can work offline, even on a flight, and the app syncs when they reconnect.
Approvers make the decision
Approve, reject, return or take any other action the workflow allows, without logging in to the source system.
Decisions write back
OneList writes each decision back to the source system, which keeps its own rules and remains the system of record.
Approve from any device, with the full context on screen
OneList gives approvers one inbox for all open tasks, a badge count on their phone that shows what’s waiting the moment it arrives, and the same information and actions on every device.

The full picture before you decide
Each task arrives with its request details, line items and documents, so approvers can decide without logging in to SAP.
