GBP is the primary sticker. USD is parity, not an FX conversion. Both numbers are canonical.
Sales Lab is a three-month term. Cascade Pro is included, and the floor is invoiced (no card at sign-up). Self-serve sign-up lands shortly; until then we create your Cascade account with Pro the same day, so you start on day one either way.
DIY follows the Podcast signup flow. It uses the same intake chassis with the DIY tier selected, then billing and onboarding continue from that record.
Foundation is invoice-billed. No card at signup. Your first invoice prorates to the billing date you elect (the 1st or the 15th). Cancellation in term is governed by the Engagement Letter.
VAT is applied where it is due. The full refund and cancellation language sits in the Engagement Letter for invoice-billed tiers and in the Stripe checkout terms once self-serve checkout is live.
