Shops rated 4.2 stars or higher are covered by the BarberOne guarantee: 30 five-star reviews in your first 90 days, or every month after is free until you get there. Shops under 4.2 can still run BarberOne — the system works exactly the same, without the 90-day promise.
One shop per area gets BarberOne. When you subscribe, you name 3 competitors who are blocked from using BarberOne while your subscription is active — we don't sell to them and we don't pitch them. First shop to pay in an area wins its picks.
At a typical £25 cut, two new customers a month cover the subscription. First place on Google Maps brings far more than two.
