rsvpBOOK billing reviews the event’s eligible billable activity rather than depending only on activity created during the current billing run. Eligible activity that was not previously billed can therefore be picked up on a later monthly, manual or end-of-event billing pass.
For exhibitor Lead Retrieval, rsvpBOOK tracks what should be billed and what has already appeared on an invoice, so a later run charges only the remaining amount. This avoids charging an already-billed booth or upgrade a second time.
Review the event invoice when a correction, cancellation or refund occurred between billing runs, and contact support when the invoice does not match the event activity you expect.
