# Discovery Call with Trellis Work

> 30 minutes with the Trellis Work team. Bring one process that eats your team's week. That is the only preparation needed. You walk us through how the work moves today. We tell you whether an agent can take it, which of your systems it would run inside, and what it would take to find out. No deck. No discovery invoice. If it is not a job we can take, we will say so on the call.

- Required fields: `name` (Your name), `email` (Email address)
- Optional fields: `notes` (Additional notes), `guests` (Add guests)
- `name` and `email` go in `attendee` and `guests` is a list of emails; every other field goes in `bookingFieldsResponses` under its name.
- `location` is optional; without it the booking uses the event’s first location.
