Restaurant Bill Itemized

The bill lands on the table, somebody opens the phone calculator, and the haggling starts: an even split punishes the person who had a salad and tap water, but adding items up by hand keeps everyone sitting there for ten minutes. Here you type one line per item, in the format name | amount | who shared it, set the service charge, and the page shows what each person owes with the charge already applied.

Every item is split evenly among the names on that line. The service charge is not divided per head: it multiplies each person's subtotal, so whoever ate more pays more of it. Two details trip people up. Names are matched literally, so Ana and ana end up as two different diners in the list. And the amount field takes a decimal comma but no thousands separator, so type 1234,56 and never 1.234,56.

Check the subtotal shown against the printed bill before charging anyone. Malformed lines are dropped without warning, and a forgotten item shows up only as that gap. Cover charge, corkage or a coupon discount go in as one extra line with the names of whoever shares it. Cents are rounded for display, so the individual shares can add up to one cent less than the total. Nothing leaves your browser.
