Short answer

How can I use AI to calculate product discounts?

Your AI uses the calculate_increase_by tool to determine new price points after applying percentage changes. This allows you to run bulk discount simulations or calculate final checkout prices instantly. You get exact figures for every SKU or coupon you feed it.

The results you get.

Where your price updates land.

The AI processes your pricing requests and delivers these specific results.

CALCULATED

New price points

The AI runs the math on your original prices. You get a list of the exact new values after the discount is applied.

PROMOTIONS

Coupon impact

Input your coupon percentages to see how they affect your margins. The AI calculates the reduction for each item.

REVIEWS

Human verification

The AI presents the final numbers for your review. You decide if the discounts are correct before applying them to your store.

LOGS

Price history

Keep track of the changes made. The AI provides the delta between the old and new prices for your records.

The workflow

What your AI does when the pricing data arrives.

The AI takes your raw price data and applies the logic you request.

  1. Ingest price lists

    Your agent reads your current product pricing from a sheet or database. It identifies the base prices that need adjustment.

  2. Apply reductions

    The AI calculates the specific amount to subtract from each item based on your percentage rules. It handles the math for every single line item.

  3. Simulate markups

    If you need to raise prices instead of lowering them, the AI performs the inverse calculation. This helps you find the right price to hit a specific margin.

  4. Finalize values
