This screen displays all amounts that have been modified or revised in a lease contract: rent, security deposit, utilities, or maintenance fees.

Each row in this table corresponds to a modification or revision.

Impact on the calculation of invoices

When a work order spans multiple periods (before and after a service call), the calculation uses the amounts in the history to determine the corresponding prorated amount.

Example

A rent adjustment took place on November 23, increasing the amount from €1,000 to €1,020.
For a 30-day month:

• 1st to 22nd: €1,000 × 22 days / 30 days = €733.33
• From the 23rd to the 30th: €1,020 × 8 days / 30 days = €272

→ Total = 733.33 + 272 = €1,005.33

The total amount of the invoice is calculated by adding the prorated amounts derived from historical data.

Delete action

A delete option is available in the history table.

• It allows you to permanently remove a line when it is no longer needed in the calculation of invoices.
• The action is visible only to users with the following Profile permission: Resources → Contract → Deleting a historical amount.
• The cancellation is recorded via the main Contract form, as the history form does not have a recording mechanism.
