What is automated, where AI helps, who signs off
Automation for the routine. A person on every decision that matters.
The reliable spine
The non-AI spine is deterministic, auditable matching, kept that way precisely because billing must be defensible: plan vs invoiced vs collected vs gateway-settled, or approved time vs invoice vs collected vs realized forex, returning a clean break list.
Where AI helps
AI is limited to matching records that do not line up cleanly across the chain and flagging the breaks for a person; statutory and revenue-recognition treatment stays prepared for the firm's CA, never auto-posted.
Who signs off
A named person signs off anything touching money, a customer promise, a regulated filing, a payment, a price, a credit decision or a people decision.
