At times the estimate you have sent a client is invoiced in parts, over time. For each part, a new invoice is created. You can link an Estimate to more than one invoice for your convenience.
Avaza allows you to link the estimate to one or more invoices. Navigate to Quotes/Estimates > Click on the Estimate you want to link invoices to.
In the drop-down menu labeled Actions, click on ‘Link to Invoices’.
You will then see a list of Invoices for the same customer that can be linked to the Estimate.
Click on the Invoices you want to link with the Estimate, and click ‘Save’.
