Custom Object & Data Model Extension — Extending the billing system's schema with your own objects and fields — project hierarchies, regulatory attributes, unusual account structures. Custom objects flow through to invoicing and the report builder, so extensions behave like native data instead of sidecar spreadsheets.
Custom Object & Data Model Extension lives in the Platform & Intelligence phase of Grow Revenue — the stage where you retain, expand, and compound revenue on the platform. In the corpus tool index this phase maps to the Analytics and Data platform and Cost & FinOpscategories.
No product category maps cleanly onto this module yet — companies typically build it in-house or cover it with adjacent tooling. See who builds vs buys across the corpus.
