Each price is what the vendor’s own pricing page shows by default. Some vendors default to annual billing and some to monthly, and a few show your local currency instead of US dollars, so the figure on their site may differ from the one here.

Workflow

1. Set up invoicing in Wave — it stays free.
2. Create one Calendly event type on the free plan.

Setup time about 15 minutes
