Within Teamwork, you can export invoices from your projects to Blinksale.
To do this, go to the Billing area of your project and and select the invoice you wish to export from the left pane.
You can choose to export both open and completed invoices.
While viewing the invoice, click the Export Invoice option in the bottom left of the invoice.
In the Export options modal, select Export to Blinksale.
The first time you do this, you will be prompted to log in to your Blinksale account.
You can choose a company to associate the invoice to, and set the number of days for the payment due.
When you have completed the export, your invoice will be available to select within your Blinksale account, ready for you to send to customers.
