What is CBMS (Central Billing Monitoring System)?

CBMS is the Inland Revenue Department's system for monitoring the invoicing activity of businesses permitted to bill electronically. Taxpayers the Department names must send invoice data to it at the moment each invoice is issued.

A shopkeeper in a light blue shirt sits at the counter of a busy general store, hands folded, with a card machine on the counter and shelves of stationery and packed goods behind him.

The Electronic Billing Procedure 2074 defines CBMS. It is the system the Department built to keep continuous watch on the invoicing activity of businesses that hold permission to bill electronically.

It brings two duties. First, billing software has to be built so that invoice data can be stored on the Department’s central server through a web service or web API. Both are ways for one system to send data to another over the internet. Second, taxpayers the Department names have to send that data at the time each invoice is issued, not in a batch at month end. For a cloud system, the tax office checks that this connection is in place before it grants permission.

Separately, the Department may connect any electronic billing system to CBMS and may inspect or test the system, the device and the vendor at any time.
