FreshBooks is an accounting software that
enables you to track invoices, expenses, and
time.
Within Teamwork.com, you can choose
to export an invoice in a project to your
FreshBooks Classic account.
You will first need to enable the FreshBooks integration in your site settings.
Go to the Finance area of your
project and switch
to the Billing tab. Select
the relevant invoice from the left
pane to view it.

Click Export
Invoice in the invoice's
bottom left.
Note: Both
open and completed
invoices can be
exported.

Select the Export to
FreshBooks option and click Export.

You can either log this as a new invoice or
add it to an already created invoice.
