See Pricing for the current tiers. In short:
- Free — song list, gigs, invoicing and the super calculator.
- Paid plans — setlist building, higher song and stem limits, and the full playback manager.
To change plan, open Billing and pick your tier. If you hit a stem limit while uploading, the dialog offers an upgrade or a one-off stem pack. Discount vouchers and complimentary access codes are applied at checkout.
