How do I see my previous invoices?

You can view your billing history by accessing your Customer Portal via your billing here: https://app.zincwork.com/company/billing

Scroll down to the bottom, locate the Billing History box, and click on the green "here" button.

You will be taken to a new page and be asked to log in to your Customer Portal where you can view all of your billing history and download a copy of your invoices.
