If you've got a run of shows on a single contract and you want one invoice per date so your analytics attribute each show to the right month, the way to do it is a multi-date event on one booking, not several separate bookings. This only works when every date has the same buyer.
Set up the multi-date booking
Confirm every date on the run has the same buyer. If buyers differ, each one needs its own booking.
Open the booking and go to the Events tab.
Create the first date in full.
Use Copy on the Events tab to duplicate it, then change only what differs — date, venue, times.
Under Events → Artist & Location, set the venue for each date individually. Each date takes its own venue.
Repeat until every show on the run is on the booking.
Then issue one invoice per date
Go to the Payments tab.
Turn on the itemize toggle. This splits the booking into one invoice per date.
Create and send each invoice as usual: Preview Draft, then Create Invoice in the Document Preview panel, then Send from the invoice row.
Analytics will now attribute each date to its correct month rather than lumping the whole run onto one.
Good to know
Terms and Events are edited separately. That's why the venue can look locked when you're on Terms — venue lives on Events, per date.
Bookings can't be merged after the fact. If you've already created separate bookings for the run, you'll need to rebuild it as one multi-date booking to get per-date invoices.
If every invoice on the run comes out with the same due date, that's a separate quirk of relative due-date rules. See the article on due dates all landing on the same day.
