Why Lock Invoices?

Your organization may prefer to lock invoices on which partial payments are made (and where the balance amount is due).  In such cases, you may see a 'lock' icon on the invoice. 

Zenoti recommends that you lock invoices to avoid potential fraudulent transactions such as:

  • Swindling the partial amount received through cash payments and deleting the record of such payments from the invoice.

  • Reducing the total due amount by applying discounts, coupons, or campaigns.

  • Today’s Sales window

  • Take Payments window

  • Search Invoice/Receipt Number window

Points to Consider

You cannot unlock invoices:

  • That belong to another center if your organization has a policy of accepting payment only in the center of purchase.

  • If the invoice is under a financial lock period.
