Go to Billing and scroll to the Invoice History section. Each past payment is listed with the date, amount, plan, and billing period.
Downloading a PDF
Each invoice row has a download icon. Click it to get the PDF invoice directly. You can also click the external link icon to open the invoice in Stripe's hosted invoice page, which has more detail.
If an invoice is missing
Invoices appear after the payment has processed. If you just upgraded, give it a minute and refresh the billing page. If a past invoice isn't showing, use the Sync button at the top of the billing page to re-fetch data from Stripe.
Invoice details
Invoices show the plan name, billing period, and the amount paid. They come from Stripe and include Stripe's standard invoice information. If you need additional business details on your invoices (VAT number, company name, etc.), you can add those in the Stripe customer portal under Billing Information.
To open the portal, go to Billing → Manage Subscription.
