What’s inside
7 guides, in reading order.
The Profit Is in the Second Sale
Winning a new customer costs everything upstream: being found, trusted, chosen. The second sale costs almost nothing, and that is where the profit is.
Onboarding That Earns the Second Job
The gap between 'yes' and 'settled in' is where second sales are won or lost. Designing the first experience so returning becomes the client's default.
Staying in Touch Without Spamming
Between their needs, you are either the name in their head or nobody. A quiet, useful rhythm of contact: rare, relevant and helpful.
Winning Back Lapsed Customers
The cheapest revenue there is: people who chose you once and quietly went dormant. One honest message, the right list, and what silence usually means.
Turning Customers Into Referrers
Turning delight into introductions, on purpose: who refers, the moment to invite it, and the habit of closing the loop that makes people do it again.
Growing the Clients You Already Have
An existing client trusts you, and there is a natural moment to offer more. Why a deeper relationship is the real prize, and how to offer without pushing.
The Audience You Own
Platforms rent you their audiences and can change the rent. Your own list of clients and referrers is the one channel nobody can take away.
Every guide in it is free to read on this site. The guidebook is the same words, laid out to read in one sitting or to send to someone.
