The Ledger and the Shopkeeper

A trade book on building a merchant rail for shops the platforms skipped — written from the release log rather than the pitch deck. Part one is the gap: the forty-tab panic, and why the obvious answer is wrong. Part two is the machine: a shop in one link, a statement that can be recomputed, quotas as a design material, the first hundred prospects, and the number that could not be dialled. Part three is the rules: never hold the money, never lie in the copy, never post to your customers. Part four is the craft — what broke, in five failure classes, and the uncomfortable arithmetic that follows.
