You can set up a client's reconciliation when their engagement is set up.
On the reconciliation step of the 'create new engagement' form, the default is to have the reconciliation Disabled.
To enable the reconciliation, click the drop-down and select 'enabled'.
If an engagement has been set up with the reconciliation disabled you can enable it by editing the client on the engagement page.
Click the ellipse button next to activate.
Select 'edit engagement'.
On the Edit engagement form, under reconciliation select 'enabled' to enable the reconciliation for that client.
