The loudest AI story in finance is job loss. The quieter story is more useful. AI is acting like a torch in a dark room. It is revealing how much of accounts and finance runs on undocumented process.
Most teams do not have a single “accounts payable process”. They have ten versions of it. It changes depending on who receives the invoice, who is on leave, which supplier it is, and how urgent the request feels. Everyone still gets bills paid, most of the time. That creates a dangerous illusion. If the outcome happens, the process must be fine.
AI breaks that illusion because it cannot automate what you cannot describe.
If you are reading the Xero practice study as a finance leader, the takeaway is not that AI will replace bookkeepers. The takeaway is that the firms adopting AI fastest already have something in place that most SMEs do not. They have documented workflows, consistent coding rules, and clear handoffs. AI makes them faster because the system is stable enough to automate.
In a business, the pain shows up immediately. The moment you try to introduce automation, approvals, or even basic workflow rules, you hit the same question again and again.
What actually happens today.
That is what AI exposes. The work is not complicated. It is just inconsistent.
Why undocumented process is the real risk
Undocumented process creates cost and risk at the same time.
It creates cost because every invoice requires a fresh set of decisions. Who approves. What budget it hits. What evidence is needed. Which email thread holds the context. Every decision becomes an interruption. Interruptions are the hidden tax on finance teams.
It creates risk because change is invisible. Bank details are updated in a hurry. A new supplier gets onboarded without a second check. An approval happens because someone wants to clear their inbox. Fraud loves ambiguity. So do errors.
When you rely on “how we usually do it”, you do not have a control. You have a habit.
Light takeaway. Start with AP.
If you want a practical starting point, start with accounts payable. AP is often the easiest process to document and automate because it is repetitive, rule based, and high volume. It also sits directly on cash leaving the business.
A simple AP process should be able to answer these questions without debate.
