How long does a merchant have to put your charge through?

Merchants typically have up to 30 days to process a charge, but this can vary based on the payment processor and the terms of the merchant agreement. After a transaction is authorized, merchants may have a set period, often around 7 days, to capture the funds. If they don't process the charge within that timeframe, the authorization may expire, and they would need to re-authorize the transaction. Always check the specific policies of the merchant and the payment processor for precise details.
