Introducing Mayday AIR: Close month end on autopilot
For decades, cars kept getting smarter and faster, but the driver still had to do the hard work. The engine handled more power, but humans still steered, braked, and navigated.
Now, in Silicon Valley, self-driving technology is showing what’s possible when machines take control of the hardest parts of the journey, letting you sit back, supervise, and step in only when needed.
Month-end accounting has followed a similar path. Tools like Excel, Xero, and QuickBooks Online made bookkeeping faster and more powerful, the engine got better, but finance teams are still left navigating the hardest calculations at month end.
That’s why today, we’re delighted to formally reveal Mayday AIR (Artificially Intelligent Recognition), the automation layer built to close your month end on autopilot.
How AIR powers Mayday, today
AIR is the technology that powers Mayday’s newest products, Deferred Revenue and Prepayments, as well as existing products BRAG and Balancer.
In each, AIR runs quietly behind the scenes, completing complex calculations in the background, surfacing recommendations in real time, and reducing your month-end adjustments down to a single click.
Here's how it works:
Deferred Revenue & Prepayments
From your central inbox, AIR scans transactions across your group, flags those that require Deferred Revenue or Prepayment treatment, and automatically generates the correct schedule based on the transaction description.
Instead of spending hours every month hunting for relevant transactions, simply review, approve and post journals in one click to Xero or QuickBooks Online.

BRAG (Bank Rec Across the Group)
In BRAG, AIR performs intelligent cross-entity matching, helping you reconcile bank feed items in one entity to bills/invoices in another, directly from Xero's bank rec dashboard.
By surfacing the right matches instantly, AIR cuts out the manual search and saves hours of time. From there, simply review, approve, and post straight to Xero in one click.

Balancer
In Balancer, AIR cross-checks your intercompany loan accounts and immediately flags any discrepancies between them.
You’ll instantly be able to identify the transaction that unbalanced the accounts and rectify the posting asymmetry.
Simply post your FX adjustment journals, or set the interest rate that should apply and AIR will auto-calculate the adjustment for you, so you can one-click post straight to Xero or QuickBooks Online.

How AIR decides what’s best for your accounts
Every decision AIR makes follows a simple pattern: First, it applies the universal rules of accounting, then it fine-tunes the decision to match the way you work. This two-layer approach ensures that every recommendation is both technically correct and contextually relevant for your business.
1) AIR applies the universal rules of accounting
AIR first applies proven accounting logic to reach an initial decision. Examples:
- Should this transaction get deferred revenue treatment?
- Should these two transactions be matched?
This first layer is pre-trained on a mix of manually generated and synthetic examples, plus datasets explicitly provided by customers with consent. It is never trained on private customer data without consent.
2) AIR tailors recommendations based on your business context
Next, AIR tailors recommendations based on what is typical of your specific accounting files. To do this, the system makes a real-time judgement based on the actions you have taken in Mayday beforehand.
The customer's data is not taken out of the production system to pre-train a model, and customers' data is not inter-mingled to make these decisions.
How Mayday AIR can transform your month end
Month end can often feel like searching for a needle in a haystack. Which payments need to be deferred or prepaid? Which transaction has thrown your intercompany loans out of balance? Where can I find the match for those tricky cross-entity reconciliations?
With Mayday AIR, the answers surface instantly. By combining accounting principles with automation and your unique business context, AIR takes the heavy lifting out of month end. The payoff: less spreadsheet stress, fewer errors, and a faster month-end close.
But don’t just take our word for it, read below how our customers are using Mayday to transform their month end:
