To disable sub-billing notarization, make sure that the GC employee's profile includes the Notary option.
Go to Accounting > Approve Sub Billing
Click on the Settings Gear Icon
Check the box that says ‘Do Not Notarize Subcontractor Billing’
This will remove the Liens to Notarize Quick Link from view and will not apply the Notary seal when they Accept Sub Bills under the Digital Lien setting.
If you're a GC who may notarize owner bills but doesn't need to require lien releases from subcontractors, doesn't need to notarize signed liens, or cannot digitally notarize liens in your jurisdiction, you can turn off the sub-billing notarization option.
