Short answer

How do I find the pre-tax price from a total?

Your AI uses the inside calculation method to work backward from a gross price to find the tax base. You'll get the exact product value before taxes are added. The breakdown of these values follows.

The results you get

Where your data lands

Once you provide a total price, your AI produces these specific outcomes.

CALCULATION

The tax base value

The AI isolates the net product price. You get the exact number used for the tax calculation.

VERIFICATION

Tax amount isolation

The AI identifies the specific tax portion included in the total. This shows you exactly how much tax was applied.

DATA

Grossed-up totals

The AI confirms the relationship between the net and gross values. You get a clear view of the pricing structure.

REVIEW

Human verification needed

The AI provides the math, but you must check the final figures against your local tax laws. You decide if the calculation meets your accounting needs.

The workflow

What your AI does when the price arrives.

The AI takes your gross total and runs the math through the connector's logic.

  1. Identify the total

    Your AI reads the gross price you provided in the chat.

  2. Isolate the base

    The AI runs the specific math to pull the tax out of the total.

  3. Validate the math

    The AI checks the result to ensure the tax base and tax amount sum back to your original total.

    calculate_tax_base

  4. Present the breakdown

    The AI gives you the net price and the tax amount separately.
