Who sells the subscription?
Paddle.com is our online reseller and the merchant of record. Paddle takes the payment, adds the right VAT or sales tax, issues the invoice and handles refunds. EMMA Aerospace Consulting provides the service.
Can my organization pay by invoice?
Yes, for Teams and API billed yearly. Write to us with the number of seats and your billing details and we send an invoice.
Are prices shown with tax?
Prices are in US dollars and exclude VAT, GST and sales tax. Paddle adds the tax that applies where you are and shows the full amount before you pay. Businesses in the EU with a valid VAT number are charged without VAT under the reverse charge.

Do universities get a discount?
