What does Apply tax after discount mean?

When enabled, tax % applies to the amount left after your discount. When disabled, the tool follows the pre-discount path you are modeling in this UI. Always align with how your company posts discounts in its GST return workflow.

When should I use Item-level vs Simple?

Simple is one basket or one headline concession. Item-level is for catalogs where each line has different base amounts and rebates—typical in distributor negotiations.

Can I mix percent and rupee discounts?

In Item-level each row chooses % or ₹. That supports mixed commercial terms on the same quote table.

Is this official GST advice?

No—it is a calculator to support commercial math. Treatment of discounts (especially post-supply) can have GST nuances; rely on your CA for compliance.

Can procurement teams use it backward from supplier quotes?

Yes—buyers model net payable after rebates to compare vendors, then record outcomes in their ERP.

Why are the three tiles useful?

They separate gross, net-after-discount, and the rupee value of the concession so you can sanity-check margin impact before approving a deal.

How to use

Use the form above, then follow these steps.

Compute discounted payables with GST awareness.

1. Start in Simple for a single Amount, Tax %, and one Discount—fast for headline promotions. Switch to Item-level when every row has different amounts and rebates (typical in negotiated B2B quotes).
2. For each discount, set Type to % or ₹. Percent scales with the line; rupees is a fixed cut from that line (or from the simple amount).
3. Enable Apply tax after discount if your workflow applies GST on the post-discount net; disable if your model taxes pre-discount amounts. Match whatever your finance team expects for that transaction.
4. In Item-level, use Add Item until every discounted position is modeled. The Amount after discount column updates per row; Remove drops a line.
5. Read the three tiles—Amount, Amount after discount, Discount (difference)—for a quick sanity check while negotiating.
6. Optionally click Generate Output to mirror a text snapshot in the Output column in addition to the live totals in the form.
