For Training

Use this to teach the change to clinic staff or internal teams. It's short by design — the fix is small.

Learning objective

After this, a learner can (1) find the discount percentage on the invoices screen, and (2) explain in one sentence why the number changed and why the new one is correct.

The one idea to teach

"Total" on an invoice is the amount after the discount. To express the discount as a percentage, you must add the discount back to get the original price, then divide. That's exactly what the fix does.

Step‑by‑step: see it yourself

  1. Log in and go to Finances → Invoices.
  2. Click Show Analytics at the top of the table.
  3. Find the Discount tile — a money amount with a small percentage under it.
  4. Click the Discount tile to filter to only discounted invoices.
  5. Note the Total and Discount amounts. Add them together — that's the

pre‑discount price.

  1. Confirm the tile's percentage equals Discount ÷ (Total + Discount) × 100.

See the walkthrough for annotated screenshots of each step.

Worked example (use this in a session)

Filtered to discounted invoices in the sandbox:

ValueAmount
Discount₺2,373.25
Total (after discount)₺18,301.75
Pre‑discount price (Total + Discount)₺20,675.00
Percentage shown11.5 %

Ask the group: "What would the old, wrong version have shown?" Answer: 2,373.25 ÷ 18,301.75 = 13.0 % — too high, because it divided by the already‑reduced total.

A one‑invoice illustration

Expand a single invoice row (the +) to show the building blocks:

  • Subtotal ₺500 − Discount ₺75 + Tax ₺63.76 = Total ₺488.76

Point out that the ₺75 discount is already gone from the ₺488.76 total, which is why you can't just divide by the total.

Common misconceptions to pre‑empt

  • "The discount amount changed." No — only the percentage's math changed.
  • "This affects all the tiles." No — only the Discount tile.
  • "The old number was closer to reality." No — the old number was inflated;

the new one is the true percent off (exact when there's no tax).

Quick check (2 questions)

  1. Why do you add the discount back before calculating the percentage?

(Because Total already has the discount subtracted.)

  1. On web and mobile, is the number the same now?

(Yes — both use the corrected formula.)
