What Discover Reason Code LP Means
Discover reason code LP — Late Presentment is raised when a merchant submits a transaction for settlement after Discover's permitted time window following the authorization. Discover requires that transactions be presented within a set number of days of the authorization date. Submitting after this window gives the issuer grounds to chargeback the transaction on procedural grounds alone.
LP has one of the lowest merchant win rates of any Discover code. The deadline is procedural and binary — either you submitted in time or you didn't. If the card was expired or the authorization had lapsed, you have almost no defense.
Common Trigger Scenarios
- Batch settlement delay. A transaction sat in an open batch for too long before being submitted for settlement — common with periodic manual batch closings.
- Backlogged offline transactions. Offline or store-and-forward transactions that were authorized without network connectivity and submitted days later.
- Hotel or car rental extended stay. A pre-authorization was taken at check-in but not settled until checkout, which may fall outside the presentment window if the stay was long.
- Manual transaction processing. Paper-based or manual transactions that were keyed in and batched well after the original sale date.
Evidence You Will Need
- Original authorization confirmation — showing the authorization date and approval code
- Settlement submission record — showing the date the transaction was submitted for settlement
- Documentation of unavoidable delay — if a system outage or network issue caused the delay, document it with timestamps

- Leaving batches open for days. The single most common cause of LP chargebacks. Batches should be closed daily or at most every 24 hours.
- No monitoring of transaction age. Without alerts for transactions approaching the presentment window, LP chargebacks are discovered only after they occur.
Response Framework Overview
- Verify the presentment date against the authorization date. Calculate the actual delay and determine if any exception applies.
- Document any extenuating circumstances. System outages, network connectivity failures, or other documented events may support a limited exception claim.
- Accept if the delay is unambiguous. With a ~15% win rate, LP chargebacks are usually better accepted than contested unless a genuine exception exists.
Prevention Tips
- Close batches daily. Daily batch settlement is the single most effective prevention for LP chargebacks.
- Set transaction age alerts. Configure your POS or payment gateway to alert when any transaction approaches the presentment window.
- Review offline transaction procedures. Store-and-forward transactions need special handling protocols to ensure timely submission.
Frequently Asked Questions
What is Discover's presentment window for LP?
Discover requires transactions to be presented within a set number of days of the authorization. The specific window depends on your merchant category and agreement, but is typically 1-3 days for standard retail and up to 30 days for lodging and car rental. Consult your acquirer for your specific limits.
Can I win an LP chargeback if it was only a day late?
The win rate for LP is approximately 15% regardless of how late the submission was. If you missed the window, you missed it. The only viable defenses are documented system failures that prevented timely submission, or a genuine factual dispute about the submission timestamp.
