Here is a list of key concepts around Flywire payment plans:
Core Plan Mechanics
| Concept Name | What It Means |
| Installment | A single scheduled payment on the plan (typically monthly). |
| Remaining Balance | What is still owed overall on the plan. |
| Next Due Amount | What must be paid for the current installment period. |
| Missed Installment | An installment Flywire has marked unpaid after the nightly processing rules run. |
| Roll-Up | Adding new eligible balances into an existing payment plan. |
| Autopay | Recurring automatic payments tied to the payment schedule. |
