Invoice lifetime
Definition
An invoice lifetime is the window during which a crypto invoice holds its quoted exchange rate and remains payable.
Why it matters
The window is finite because the merchant absorbs the price risk. Paying after expiry routes funds to a dead invoice, which then needs manual reconciliation. At ninety minutes, ours comfortably outlasts a Bitcoin confirmation at normal fee levels.
