You can merge multiple invoices by clicking on the checkbox on the left side from the invoice number.

After the field is checked the invoice items will be auto added in your existing invoice that you are currently creating or edit.

Additionaly you can mark the merged invoices as cancelled instead of deleting because merging invoices will create gaps in invoice numbers. Please do not merge invoices if you want no gaps in your invoice history. You also have the option of manually adjusting invoice numbers if you want to fill the gaps.

Cancelled invoices are excluded from the reports and overdue reminders are disabled.
