E-commerce Fundamentals

The first book got your store open. This one teaches you to run it.

E-commerce Fundamentals is the advanced follow-on to Intro to E-commerce — written for store owners whose shelves are stocked and whose first sales have landed, and who now want the storekeeper's craft: reading the three numbers that steer a store (sessions, conversion rate, average order value) with a real month worked end to end, operating the pricing ladder with a repricing cadence and deliberate holds, grading suppliers on a monthly scorecard and replacing the failures without customers feeling the swap, building product pages that answer a stranger's six questions, and judging advertising by profit per sale instead of applause — break-even cost per click included.

It goes deeper on keeping customers — the arithmetic of the second order, bundles and ladder follow-ons, post-purchase offers, and a service-recovery playbook for when things go wrong anyway — then turns to money discipline: payout lag versus supplier charges, a reserve sized from your own numbers, and the subscription audit that hunts fee creep. It closes with scaling without breaking trust: the second-store math, hiring chores without outsourcing judgment, and the cracked-foundation list that says 'not yet.'

No jargon without a translation, no hype, no get-rich-quick promises — because there aren't any honest ones.
