There is rounding in place that rounds the invoice duration when you roll up your visits into finance manager. The rounding is configured within the purchase order and on the rate that attaches to the visit.
If the invoice duration is calculated in 15-minute increments, where 23 to 37 minutes has a charge duration of 30 minutes, then the bandings would be as follows.
23 to 37 = 30
38 to 52 = 45
53 to 67 = 60
68 to 82 = 75
83 to 97 = 90
98 to 112 = 105
Each finance manager setup is different and is configured based on the needs of your Local Authority. If you have any questions regarding your setup or would like to make any changes, please raise this with your local authority.
