Business

Margin, markup, marketplace fees and what an ad click is really costing you.

The gap between what something sells for and what you actually keep, in as many pieces as it comes apart into. Margin and markup are the pair that does the most damage: a 50% markup is a 33% margin, and pricing a product as though those two numbers are interchangeable is how a shop ends up losing money on every sale it celebrates.

Pricing, fees, spend, and paperwork

Pricing is margin, discount, break-even, unit price and the free-shipping threshold — that last one answering what the threshold costs you against what it earns back in larger baskets. Fees are the eBay and general marketplace calculators plus VAT, which sits here rather than under Finance because it is a trader’s obligation with a reclaim on the other side of it. Personal sales tax stays with Finance.

Advertising is CPM, CPC and CPA, ROAS, lifetime value, conversion rate, email open rate and newsletter growth: spend in, and an honest answer about what came back out. Then the paperwork — business cards, certificates, Gantt charts, seating charts and both signature generators — which produces a document rather than a number. Two date tools live here for the same reason: range overlap and the data retention date are contract questions wearing a calendar’s clothes.
