Record money received
Open the booking and use Received. Pick Payment received, the method, the receipt reference, and when it arrived.
Approve as a second user
Another user with canManagePayments opens the booking, finds the evidence under Settlement approval, and approves it.
Mark paid
Enter the approved reference in Payment and choose Mark paid.
Issue tickets
Choose Issue ticket. One ticket per passenger is created with a coupon per segment.
If the carrier has an active Stripe provider the traveler can instead pay from Manage booking and tickets issue automatically on return from Stripe. For a refund, record "Refund sent", have it approved, then use Record refund. See Payments and refunds.
