- where do i find the invoice of my current subscription? (100 stops - month)
- what is the difference between business and normal subscription, and why is the business subscription more expensive?
When you upgrade via PayPal you will not receive an invoice, as the payment is made on beforehand, but you will receive a receipt via email. See our docs.
Business subscriptions are more expensive because they involve more costs and more work. Business users generally require more resources, requests and support.
