Practical notes from the LAM methodology.
Explain the next step
Useful confirmation messages tell customers what happened and what comes next. Failed-payment messages should provide a clear action without exposing technical details or implying a successful order.
Give operations a place in the plan
Refunds, duplicate notifications and subscription changes deserve attention before launch. A payment integration is complete only when the team understands its everyday operation.
