Check event rental shortages across inclusive dates

Understand inclusive overlap

A booking ending on the event start date is considered overlapping. That keeps a same-day return and pickup in the review set until a real buffer or handoff plan is recorded.

available = on hand - quantity from overlapping bookings

Read the default shortages

The illustrative event reports 3 short item lines and 41 short units: 30 plates, 10 chairs, and 1 table after overlapping bookings are reserved. The string light row remains available.

The Friday wedding chair booking overlaps the Saturday event range, so its 30 chairs reduce the available chair count.

Resolve a short row explicitly

A shortage is a sourcing prompt. Add a real hold, repair buffer, pickup window, or external supply as a dated row and rerun the check instead of silently substituting a different item.
