Centralized billing

Centralized billing is a system in which all charges incurred across multiple services are consolidated rather than being billed separately. 

It simplifies companies’ payment processes by grouping travel-related expenses into a single invoice. Instead of employees or departments handling separate payments for flights, hotels, ground transportation, and other travel services, all charges are collected through one central account, typically managed by a travel management company (TMC).

At the end of a billing cycle (weekly or monthly), the TMC sends an invoice to the client company, listing all transactions.
