The process in plain English
An employee submits an expense claim with receipts. Finance checks it against policy. Compliant claims under a threshold are approved by the line manager; larger ones also need finance approval. Approved claims are paid; non-compliant or rejected claims are returned to the employee to fix or withdraw.
Steps and their BPMN elements
| Step | BPMN element | Lane |
|---|---|---|
| Claim submitted | Start event | Employee |
| Validate receipts vs policy | User task | Finance |
| Policy compliant? | Exclusive gateway | Finance |
| Over threshold? | Exclusive gateway | Finance |
| Manager approval | User task | Manager |
| Finance approval (large) | User task | Finance |
| Approved? | Exclusive gateway | — |
| Reimburse employee | Service task | Finance |
| Return with reason | Send task | Finance |
| Expense paid | End event | — |
| Claim returned | End event | — |
Key modelling points
- Two sequential gateways: policy compliant? then over threshold? — keep them distinct rather than one tangled decision (see common mistakes).
- The return path loops non-compliant claims back — a realistic touch.
- Validation stays a user task; the gateway only routes on its result.

Frequently asked questions
How do you model expense reimbursement in BPMN?
Start when an employee submits a claim, validate receipts against policy with a user task, route by amount and policy compliance through exclusive gateways to the right approver, then pay via a service task. Non-compliant or rejected claims return to the employee with a reason.
