Invoice-based billing allows you to pay for your Cloudsmith account as an invoice rather than via debit/credit cards. This is a convenient option for larger organisations or where there are strict requirements in how vendors are paid. It also tends to be much cheaper than other payment methods.
Access Entitlements (Advanced)
Like basic entitlements, advanced entitlements allow you to control who has read-only access to your repositories, to download packages and assets. However, you can also limit what access an entitlement has by search, or you can limit how long a token is valid for by time. As a vendor, you can power your license-based distribution with tokens that are dynamically created via the API, based on your customer needs.
Restrict or grant access to your packages based on geographical location, IP ranges or specific IP addresses. If you need to add physical location security to your package management, then Geo/IP Restriction is what you need.
