How does SplitBill automatically calculate net balances?

SplitBill uses an optimized debt simplification algorithm. When expenses are added to a trip, the matrix calculates who paid and who owes, minimizing the total number of transactions needed to settle all debts.

How do I invite friends using their Internal ID?

Every registered SplitBill user has a unique Internal ID (e.g., SB-A1B2C3) visible on their profile. Enter their ID in the workspace or trip invite field to send an instant invitation with live notifications.

What happens when a trip is closed?

Closing a trip locks all expenses, splits, and recorded settlements into read-only mode to prevent modifications. You can still view overview statistics and export PDF or CSV reports anytime.

Can I export trip expense reports?

Yes! Open the Expenses tab on any trip detail page and click the Export dropdown to download a high-resolution PDF statement or an Excel-compatible CSV file.
