The idea
An opening proposal, open to a different shape.
Two things up front. First, this is a starting point for a conversation, not a take-it-or-leave-it offer, every number, term and surface below is open to discussion, and if a completely different shape works better for you (different price, fewer surfaces, longer or shorter term, performance bonus instead of a flat fee, anything) I would much rather hear it than have you walk away. Second, the maths I have used to land on the number, modelled honestly: one Shop-tab visit per active user per month, 10% click into a product, 5% conversion at £85 AOV. At today's 64 WAU (~250 MAU during a season) that is roughly £100/month gross referred to you, below the £150 fee, which is the honest read at today's scale. At 1,000 MAU (a modest September restart), ~£425/month. At 5,000 MAU (launch-week pace sustained through a season), ~£2,100/month. The symmetric exit below is how the downside is bounded if September never lands.
Excludes VAT. The 2,500 MAU renegotiation trigger and the 100 MAU exit clause are mirror images of each other, designed so both sides can ask to revisit if reality moves materially in either direction. MAU is reported from PostHog and the dashboard is shared monthly so the numbers are not my word against yours.
