Online food ordering system flowchart
This flowchart follows a food delivery order from the moment a customer places it to one of two endings: delivered or cancelled. It is a good starting point for students drawing a system flowchart for a project or exam, and for developers sketching the order flow of a delivery app.

How the order flows
The diagram has one start point, one decision and two end points. Ovals mark start and end, the diamond is the decision, and rectangles are process steps.
- Customer places order: the flow starts when the customer submits an order.
- Restaurant accepts?: the restaurant decides whether it can take the order.
- Yes branch, step 1: Prepare food.
- Yes branch, step 2: Assign delivery partner.
- Yes branch, step 3: Pick up order from the restaurant.
- Yes branch, step 4: Deliver to customer.
- Yes branch ending: the flow ends at Order delivered.
- No branch: the customer gets a Refund customer step, and the flow ends at Order cancelled.
The decision point
Restaurant accepts? is the only branch in the diagram. The Yes path runs through four steps in a straight line to Order delivered. The No path has a single step, Refund customer, before it reaches Order cancelled. Because the refund happens on rejection, the diagram assumes the customer pays when placing the order.
| Shape | Meaning | Nodes |
|---|---|---|
| Oval | Start / end | Customer places order, Order delivered, Order cancelled |
| Diamond | Decision | Restaurant accepts? |
| Rectangle | Process step | Prepare food, Assign delivery partner, Pick up order, Deliver to customer, Refund customer |
How to adapt it for your project
- Add a payment check after Customer places order if payment can fail.
- Add a decision after Assign delivery partner, such as "Partner available?", with a loop back to retry.
- Split Customer places order into browse menu, add to cart and checkout if you need more detail.
- Add customer-side cancellation as a second path into Refund customer.
Tip: Keep every decision diamond labelled with a clear question and label each outgoing arrow (Yes/No). Examiners and reviewers check that every branch reaches an end oval.
