You can define the threshold for an Invoice run with the help of Auto Approve Invoices.

When you process an Invoice Run, you can define the Invoices that you want to Auto Approve, by the value of the Invoice Amount.

For example, as an administrator, if you want to automatically approve only selected invoices with an Invoice Amount less than or equal to $1000, you can do by specifying the threshold amount in the Auto Approve Threshold. Conga Billing automatically approves the processing of such Invoices based on the defined threshold.
