## What you can do here
Choose manual issuance, WooCommerce or a verified backend to deliver [licenses](/docs/v1/start/glossary#license) after confirmed purchases.

Start with [manual issuance](/docs/v1/guides/manual-issuance) if you only want to send keys. Use the native WooCommerce connector for its combined import; advanced provider recipes require a trusted verification backend. KDPika platform billing is separate from your [customer](/docs/v1/start/glossary#customer)'s purchase.
