The Service History tab shows, for each elevator, whether the maintenance the contract asks for happened, and how many callbacks it had compared with what the contract allows. It answers questions like “which units missed a visit this year?” without adding up tickets by hand.
The tab is on a property’s detail page, an elevator’s page, and a contract’s detail page. Property pages are consultant-only; clients can see the tab on the contracts and elevator pages they can open. Only consultants, and Lift AI admins, can mark a visit as not performed.

​
Open Service History

Open a property, an elevator, or a contract, and select the Service History tab. See Open a property’s details, View an individual lift, or View contract details. The tab has two views, Maintenance visits and Callback/Emergency Visits. Both use the Period dropdown on the tab: Last 12 months (the default, including the current month) or one of the last four full calendar years. This dropdown is separate from the Period in the filter bar. Each grid has one row per elevator and one column per month. Use the search box to find a unit, and select an elevator’s name to open its page in a new tab. On a contract, a Property column shows which building each elevator is in.

​
Read the Maintenance visits grid

The Requirement column shows what the contract asks for, for example “2 visits / 3 months”. Each period is one cell; a period longer than a month spans its months. Each cell shows an icon for its state; hover over it to see the state by name: The Done, Partial, No record, and Not performed columns count each row’s periods in those states. The grid is sorted by No record, so the units with the most unexplained gaps come first. Select a cell to see the detail: what the contract expects, the visits or hours recorded with links to their tickets, and a history of marks and of records arriving.

​
Mark a visit as not performed

When you know a visit didn’t happen, for example the service provider confirmed it was missed, record that so the gap is explained rather than left as No record.
1

Open the period

Select a No record cell. You can only mark a period that no maintenance record has reached.
2

Mark it

Select Mark as not performed. The cell turns to Skipped and the row’s Not performed count goes up.
You can undo this at any time: open the cell and select Remove not performed. If a maintenance record for that period reaches Lift AI later, the record wins and the cell changes to Partial or Done. The mark stays in the cell’s history.

​
Read the Callback/Emergency Visits grid

The Requirement column shows the contract’s yearly limits per elevator, for example “≤3 callbacks” and “≤3 emergency”. Each month cell shows that month’s callbacks, with a red up arrow when there were more than the month before and a green down arrow when there were fewer. The Callbacks column totals regular, deferred, and emergency callbacks over the period, and Emergency counts how many of those were entrapments. A red warning icon next to an elevator’s name means it’s over its contracted callback rate, emergency rate, or both. Hover over the icon to see the unit’s yearly rates against the limits. Select a month cell to see that month’s callback tickets, with links to each one.
