ChatGPT vs Copilot 
👉 Download my 100 ChatGPT Tips: https://lnkd.in/e6VC4Rhq

Which GenAI should you actually use: ChatGPT or Copilot?
That’s a question I get a lot

That’s why I created this guide for you.

Here are my clear rules on which one to choose:

1 - INDIVIDUALS & SMALL BUSINESSES

You’re an individual or small business, not fully in Microsoft or Google?

Recommendation: ChatGPT (take the Teams license if you’re a small business; it has enterprise-grade security and is SOC2 Type II compliant).

It has the best functionalities, best interface, and always ships innovative models first.

Drawback: it's not yet fully connected with your business data (though it's improving with connectors to Google Drive, Calendar, OneDrive, and Outlook).

This is the one I use for my team and me.


2 - BUSINESSES USING MICROSOFT

You guessed it: Copilot.

Why?
Because Copilot 365 with Microsoft 365 brings AI directly to your work data.

This is Copilot’s most underrated feature and the main reason to choose it if you’re a Microsoft shop.

Try this:
Step 1. Switch to "Work" mode
Step 2. Type "/" in Copilot and access a doc
Step 3. Enter the file name
Step 4. Ask Copilot to perform a task on it
Step 5. AI works with real context from your files

That’s a huge advantage over ChatGPT or tools not connected to your work data, where you need preliminary steps to provide context

If you already trust Microsoft with Outlook and Excel online, Copilot makes perfect sense:
- No extra vendor to manage
- Your confidential info stays in Microsoft’s security graph (the same Copilot uses)
- No separate user/license management (it’s tied to Microsoft 365)

And Copilot is just getting started
I got insights from Microsoft Teams telling me that they are working to integrate AI deeper, with more promising features coming soon

Bottom line
Choose based on where your work lives, not the hype
Tell me which one is your favorite one and why

Atomic Habits for Finance
👉 Download my 48 Laws of Power applied to Finance: https://lnkd.in/edgY7bWe

What if the real difference between an average finance team
and a world-class one wasn’t talent… but habits?

Most teams try to “work harder” during closing, forecasting, or budgeting.
But the truth?

Finance improves in the same way individuals do
through tiny, consistent behaviors that compound over time

That’s why I built this cheat sheet: to translate Atomic Habits into Finance habits you can start today

Here’s what’s inside:

1. How Atomic Habits actually work
Identity, systems, and tiny gains matter more than intensity.
A finance team that sees itself as reliable and data-driven behaves differently.

2. The 4 Laws applied to Finance
#1: Cue – Make it obvious
– Clear dashboards
– Daily stand-ups
– Simple finance scorecards
– Habit stacking during closures and POs

#2: Craving – Make it attractive
– Temptation bundling (variance analysis + coffee)
– Social groups that celebrate clean and on-time data
– “Forecast accuracy leaderboard” for business units
– Motivation rituals in meetings

#3: Response – Make it easy
– Smaller, more frequent forecasting cycles
– Pre-built templates for P&L, variance, board packs
– Standard naming conventions
– The 2-minute rule: if it takes <2 minutes, do it now

#4: Reward – Make it satisfying
– Show reduced cycle times and error drops
– Visible payoff dashboards
– Track on-time submissions & forecast accuracy trends
– Reward behaviors that stick

1% daily improvement
A finance team improving 1% per day becomes 37× better after one year
Tiny process improvements beat massive transformation projects

How to break bad habits
– Make them invisible (remove distractions)
– Make them unattractive (highlight cost of errors)
– Make them difficult (add friction to bad habits)
– Make them unsatisfying (reinforce consequences)

Finance excellence isn’t built in Q4 but it’s built in the daily routines you repeat all year

💬 Which habit are you implementing first?

CFOs are done waiting for perfect systems

They’re building scrappy, smart, and scalable automation themselves

Here are 3 ways finance teams are scaling with AI (without waiting for IT)

1. Traditional Automation

 Handle repetitive tasks with simple scripts
→ Beginner:
 Use Google Apps Script to clean & format data in Sheets
 • Set it once, it runs forever
 • No coding background needed
 • Saves hours cleaning reports
→ Advanced:
 Use Python to merge and format multiple CSVs
 • Auto-merges files from folders
 • Removes duplicates
 • Saves hours each month on reporting


2. AI Workflows

Use Custom GPTs to categorize your expenses
Steps:
 • Create a Custom GPT (role = expense categorizer)
 • Upload your CSV
 • GPT assigns categories like "Office Supplies" or "Travel"
 • Refine for edge cases
 • Download a categorized report for your accounting system
Result: No more manual tagging or spreadsheet hunting


3. AI Agents

Automate credit card categorization with no clicks
→ Tools: N8N + OpenAI API
 • Detects new CSVs with transactions
 • Cleans + standardizes the data
 • Uses AI to categorize based on vendor description
 • Final file is mapped automatically
Great for:
 • Expense categorization
 • Invoice extraction
 • Report generation
 • Finance chatbots
