Because a group bought through five subsidiaries looks like five mid-sized customers. Nobody notices it is the largest relationship you have until somebody adds it up by hand for a board pack.
A hierarchy links company records as parent and child to any depth, so subsidiaries stay separate operating records while the group can be read as one customer.
Each company keeps its own deals, tickets and invoices. Reporting can be run at the node or rolled up through it, and the rollup is a view of the same rows rather than a second set of totals.
Cavendish Group holds four subsidiaries. Individually the largest is a £40,000 account; rolled up the group is £310,000 across eleven deals, with two subsidiaries buying nothing at all.
It is a commercial hierarchy, not a legal one. It records how you sell to and report on a group, and makes no claim about ownership or consolidation for statutory accounts.
Books can consolidate billing or keep it separate per entity, pipeline reports roll up through it, and Desk can escalate on group standing rather than on the size of the entity raising the ticket.
