Why We Recommend Hitting “Pause” on Xero JAX
You may have noticed—or will soon notice—a new feature popping up in your accounting software: Xero JAX (Just Ask Xero).
JAX is Xero’s new generative AI assistant. One of its most touted features is the ability to automatically code and reconcile your bank transactions. The promise is enticing: fully automated bookkeeping that saves you hours of admin time.
However, while the technology is impressive, we strongly advise against using the fully automatic coding features at this stage.
Here is why relying on JAX for your bank reconciliation could cost you more in the long run.
The Problem with “High Confidence”
JAX is designed to handle “high-confidence” matches, aiming to automate roughly 80% of your bank lines. In accounting, less than 100% accuracy isn’t enough to keep the tax office happy.
If you turn on “hands-off” automation, you face two distinct risks:
-
Silent Errors: If you stop reviewing the “Reconciled” page because JAX is doing it for you, incorrect matches will sit unnoticed. This leads to misstated revenue, wrong expense categories, and incorrect GST claims.
-
The Complexity Trap: AI struggles with nuance. JAX is prone to making mistakes or skipping items entirely when dealing with:
The Hidden Cost to Your Business
The most dangerous aspect of automated coding is that the issues usually don’t show up until month-end, year-end, or (worst case scenario) during an audit.
Cleaning up messy data is significantly more expensive than entering it correctly the first time.
If JAX miscodes your transactions throughout the year, your accountant will need to spend considerable time unpicking and fixing the file before they can lodge your tax return. This additional labor will inevitably lead to higher accounting fees for your end-of-year work.
Our Recommendation
Technology is moving fast, and AI will eventually be a massive asset for small businesses. But for now:
-
Do not enable fully automatic reconciliation/coding without consultation.
-
Maintain human oversight: Even if JAX suggests a match, cast a human eye over it to ensure the GST and account codes are correct.
-
Stick to Bank Rules: Traditional Xero “Bank Rules” that you set up are still the safest way to automate recurring transactions because they follow strict logic, not guesses.
We want to help you keep your accounting fees down and your data accurate. “Set and forget” is not a strategy that works for bookkeeping just yet.
