This guide provides comprehensive instructions on how to manage hire periods and invoices effectively, particularly when it comes to swapping out items or adding new items during an ongoing hire period within the On Hire Invoice system.

If you need to swap out an item during a hire period while maintaining the same invoice, please follow these steps:

1. Utilize the Item-Specific Dates feature to return the original item.

2. After returning the original item, add the new item to the invoice with a Hired-From date that is set to 1 minute after the previous item's return date.

3. Manually trigger Autocalc to ensure that item prices reflect the new dates accurately.

To add new hire items to an invoice mid-hire and charge from a different date/time than the original "Hired From" date/time, follow these steps:

1. Click on the "Show Item Details" text on the On Hire invoice to expand the Invoice Lines and view item line-specific dates.

2. In the Code column, on a new row, search for and select the new item.

3. Enter a Hired From date against the line item for the new item to indicate when it has been put on hire.

4. Optionally, click the AutoCalc link to re-calculate quantities if needed.

It is important to remember that the invoice is typically issued after all items have been returned. Therefore, it is acceptable to leave quantities as they are and re-calculate once everything is returned.

By following these steps, you can efficiently manage item swaps and additions within On Hire Invoices, ensuring accurate invoicing and tracking of hire periods.
