N.B. This is an optional feature, so it will only apply if requested. If you require more protection over the changes that can be made to sales invoices, contact the support team to enable the Invoice Locking feature.
PDF Only Invoices
By default, you have the option to create the invoice document in both Word and PDF. When you have the stricter invoicing controls enabled you will only have the option to generate the invoice as a PDF.
This protects against manual changes being made to the Word version.
The limitation being that you will no longer be able to make any final amends to layout or wording when the invoice is generated from CMAP.
Invoice Editing Disabled
Once an invoice has been created and assigned an invoice number, you will no longer be able to make any changes to the details of the invoice in CMAP. The only option will be to raise a credit for the invoice if changes are required.
As changes will no longer become available after the invoice has been created, there is an additional "Are you sure?" prompt at the point of invoice creation. This will warn the user that if they proceed to create the invoice, they will not be able to make any subsequent changes. If they would like to review the document, instead they should use the "Create Draft" option.
