- The module switch — Marketplace is optional, and needs Accounts on (§0.6); the marketplace operator profile starts with it on.
- The seller fields — the flag, status and tier on supplier records (§13.5) are the module's register configuration: tiers are your own labels, so name them once and use them consistently — commission rules match on the words.
- Commission rules — the standing price of your platform (§13.5): the house rule every marketplace needs, plus the tier and category rules above it.
- The chart — the commission income account your postings credit, and each seller's payables control account on their supplier record (Chapters 7 and 4), decide where the module's money stands in the books.
- Number sequences — the MKL- and MKO- numbers come from the company's number sequences (Chapter 16).
- Permissions — listings, rules, orders (record, post, reverse) and the seller pipeline actions are separately grantable.
Configuration mechanics live in the Implementation Manual; what the settings do is what is written here.
