ChatGPT Apps will end finance jobs and change Office of the CFO forever
I used the new ChatGPT Apps SDK to build a set of finance apps that show how CFOs will manage the entire close, forecast, and reporting process from a single chat.
Imagine you open ChatGPT on a Monday morning. And no Excel crash waiting to happen. You type:
“I want to do my month end close...”
ChatGPT activates the Trial Balance Loader App
This Substack is reader-supported. To receive new posts and support my work, consider becoming a free or paid subscriber.
Within seconds, you can see:
Revenue is mapped cleanly and with high confidence.
OpEx across EU entities still has a few unmapped lines.
There’s likely a rounding or FX imbalance to investigate.
There are no CSVs or ERP screens and no loading delays either. The data comes to you in your workspace and with issues already triaged.
This is the future of the finance system of record. The model orchestrates the apps. The human orchestrates the insight. You don’t think about where to click.
You just say:
“Load my TB.”
Sam Altman doesn’t want you to jump between tabs, juggle dashboards, or export files. He wants people to give interface, memory and continuous workflow.
OpenAI is building the operating system of work.
2026 is the year AI stops being something the FP&A analyst plays with and becomes the foundation of the finance stack.
By the end of this letter, you’ll see why the future of finance is different than you think.
Let’s dive in.
Why 2026 is The Most Pivotal Year for Finance
Every finance generation gets one reset.
ERP in the 2000s.
Cloud in the 2010s.
AI in 2026.
This isn’t about hype. It’s about timing.
All the ingredients are ready.
Data integration, secure models, and CFOs who’ve run out of patience for manual work. By 2026, every major ERP, BI, and planning platform will have an AI layer baked in.
Boards will expect answers on demand. Not in QBRs.
Investors will ask, “What is the scenario if sales dip 8%?” and expect an answer before the coffee gets cold. Finance teams that still rely on spreadsheet chains will look ancient. Teams that embrace conversational workflows will look prophetic.
In 2026, apps in ChatGPT will tie everything together through conversation.
OpenAI isn’t worth half a trillion because it talks well. It’s worth that because it’s quietly rebuilding how the world works. You don’t get to a $1 trillion IPO by selling chatbots.
Think of ChatGPT not as a chatbot but as a workspace that can run apps directly in conversation.
Say:
“Spotify, play focus music.” ChatGPT opens the Spotify app and plays it.
Say:
“Canva, build a slide deck.” It opens Canva and starts designing.
Now replace those with finance verbs:
“Forecasting App, model a 10% cut in marketing.” “Expense App, show me vendors over $50K.” “Close App, reconcile cash and AR.”
That’s the leap. You will move from outcome over application.
You won’t care which system it uses, only that it delivers. ChatGPT will have hundreds of apps behind the scenes to complete your task. You’ll ask once, and it will decide what to call forecasting models, data warehouses, and BI connectors. then return a single answer you can act on.
Today that entry point is chat. Soon it will be voice. Eventually, interfaces we haven’t even invented yet, smart glasses, ambient agents, and AI terminals that listen and act.
The medium will change but the principle won’t:
Finance will move from screens to speech, from clicks to commands. You’re running your office instead of typing prompts. These apps might sit on top of your real data, your real systems.
They may not replace QuickBooks or NetSuite.
But they will speak to them.
And they let you work the way your brain works: conversationally.
The friction in finance is distance. Distance between knowing and doing. Between questions and data. Between insight and action.
And apps in ChatGPT will close that gap.
You ask and it executes.
No more “let me pull that.” No more “give me a day.”
It’s finance without friction.
As simple as that.
You can simply say in the chat to run the reconciliation
Imagine after you successfully loaded and matched the trial balance. Then you can run the reconciliation and select the CFOOffice.io Reconciliation workbench app.
The Reconciliation Workbench App launches instantly in the same workspace.
I’m not opening the ERP or logging into bank portals and exporting CSVs.
You interact with the app by just clicking in the app card or keep chatting if you want to.
The app matches transactions automatically, flags three exceptions, and even proposes the correcting entries.
Then I simply reply:
“Go ahead and post the proposed journal entries.”
…and it posts them.
The chat interacts back with the app.
But the point is bigger than one or two apps.
Imagine what is possible.
The Bottom Line
ChatGPT Apps will become the new front end of finance.
You’ll run month-end closes from a single chat, combine multiple apps, read emails, browse the web, and pull live data.
All inside one continuous workspace.
And 2026 is the breakpoint.
OpenAI can get bigger than Google and Microsoft.
Those who experiment now will define what the modern CFO office looks like. Wait, and you’ll still be formatting slides while someone else is running their close in chat.
The spreadsheet built accuracy.
The conversation will build advantage.
And that’s all for today.
See you on Thursday!
