CRM and sales glossary

This glossary explains the words that come up when a small business starts managing customers, sales and invoices in one place: what each term means, how it is usually calculated and where it shows up in day-to-day work.

Every entry links to a short guide that gives the definition first, then an example and the common mistakes. Examples are hypothetical and rounded, never real customer data. New terms are added as they are published, so the list keeps growing.
