If you've got an instance where visits are being invoiced by actual start time but planned duration, you need to check the settings relating to this and amend them accordingly.
To check these settings please follow these steps:
Click Settings, Finance, Invoice, then Rate Sheet.
Click on the invoice rate sheet, then click Revision.
Check Use Start Time and Use Duration settings.
If both are set to Actual, but the invoice still picks up Planned Duration, you need to check the EMS rule. If the EMS rule hasn't been selected, by default it uses actual start time with planned duration.
To check and select the EMS rule, please follow these simple steps:
Go to Settings, Service User, Funder, Types.
On the General tab, the EMS rule must be selected.
