When creating a new depot, you need to apply the invoice cost centre so that invoices and pay runs will link to the selected cost centre.
Setting cost centres to a depot
Navigate to the my company page. From here, click into depots on the top toolbar. Then, select the depot you want to apply a cost centre to.
Once you have selected the depot, scroll down to the cost centre section. Choose the cost centre you want to apply to the depot, then click save.
