Supplier prices change every week, and usually, they go up without anyone telling you. If you aren't checking your invoices every week, your profit margins are slowly bleeding out.
The Secret: Use AI as your Auditor. Instead of you spending hours on a calculator, let AI scan your invoices and alert you to price hikes.
The "Invoice Auditor" Workflow
- Snap a Photo: Take a clear photo of your invoice from last week and your invoice from this week.
- Upload to AI: Use an AI with "Vision" (like Gemini or ChatGPT) and upload both photos.
- Run the Prompt: Copy and paste the prompt below.
The Prompt:
*"I am uploading two photos of invoices for my restaurant. One is from last week, and one is from today.
Your Task:
- Compare the unit prices of every item on both invoices.
- Create a list of any items that have increased in price.
- Calculate the percentage increase for those items.
- Tell me the total 'extra cost' this week based on the quantities I purchased today compared to last week's prices.
Be precise and highlight any price hike over 5% in BOLD."*
Why This Matters
- Immediate Leverage: When you see that your cooking oil went up by 12% in one week, you can call your rep immediately and ask for a credit or find a new supplier.
- Stop the Bleeding: Finding a $0.50 increase on an item you buy 100 of every week saves you $200 (R3,500) per month.
- Time back: This audit takes 60 seconds instead of 60 minutes.
