How to Show Item Quantities and Taxes on Invoices

The Quantity and tax sub-section in the Visual Editor controls whether total item quantity and per-item tax details appear on your invoice. You can display a total quantity summary row at the bottom of the items table, show the tax rate for each line item, and show the calculated tax amount per item. These fields help ensure your invoices meet tax compliance requirements and give customers full transparency on how taxes are applied.

Open the Quantity and tax settings

1. Open the Invoice Falcon app from your Shopify Admin.
2. Click Templates in the left navigation menu.
3. Click on the template you want to customize (or click Edit on the template row).
4. Scroll to the Visual editor section and click the Open visual editor button.
5. In the left panel, click the Items information section to expand it.
6. Scroll past the Product details and Pricing and discounts sub-sections to find the Quantity and tax sub-section.

Available quantity and tax fields

Each field has a checkbox to toggle it on or off. Check the fields you want to display, then click Save changes.

Show total qty

• Adds a Total items summary row at the bottom of the items table (in the table footer).
• Displays the total number of items across all line items in the order (e.g., if you have 1 + 2 + 3 items, it shows "6").
• The row shows the label "Total items" on the left and the total quantity number on the right, aligned with the Quantity column.
• Useful for orders with many line items where a quick count helps with packing and fulfillment verification.
• Off by default.

Show item tax rate

• Adds a Tax column to the items table, next to the Unit Price column (or Discount column if enabled).
• Displays the tax rate(s) applied to each line item as a percentage (e.g., "VAT 10%", "VAT 5%").
• If an item has multiple tax lines (e.g., state tax + county tax), each rate is listed on a separate line within the cell.
• The column header uses the translated label "Tax" (or the equivalent in your invoice language).
• On by default.

Show item tax amount

• Adds a Tax amount column to the items table, next to the Tax rate column.
• Displays the calculated tax amount for each line item with the currency symbol (e.g., "$58.65"). If no tax applies to an item, it displays "$0.00".
• The column header uses the translated label "Tax amount" (or the equivalent in your invoice language).
• On by default.

Where quantity and tax fields appear on the invoice

• Show total qty — appears as a footer row at the bottom of the items table, below the last line item. It spans across columns with the label "Total items" and the total count aligned under the Quantity column.
• Show item tax rate — adds a column to the items table header and each row. The column appears after the Unit Price column (or after the Discount column, if the discount column is enabled).
• Show item tax amount — adds a column to the items table header and each row. The column appears after the Tax rate column.

Enable or disable quantity and tax fields

1. In the Quantity and tax sub-section, check or uncheck the fields you want to show or hide.
2. Review the live preview on the right — the items table updates immediately to show or hide the columns and footer row.
3. Click Save changes at the top of the Visual Editor.

Known limitations

• Tax data comes from Shopify — tax rates and amounts are calculated by Shopify based on the store's tax settings and the customer's location. You cannot override tax values from within Invoice Falcon.
• Multiple tax lines per item — if a line item has multiple taxes (e.g., federal + provincial), all rates are stacked in the Tax column cell. This may make the cell taller for items with complex tax structures.
• Items with no tax show $0.00 — when the Tax amount column is enabled, tax-exempt items display "$0.00" rather than being blank.
• Total qty counts line item quantities — the total quantity is the sum of all line item quantities in the order. It does not count unique products — it counts total units ordered.
• Per-item tax vs. order-level tax — this section controls per-line-item tax display. The overall tax total shown in the Order total section is controlled by a separate setting.
• Settings are per-template — quantity and tax settings are saved independently for each template.

Troubleshooting

FAQs

Q: Which fields are on by default?
A: Show item tax rate and Show item tax amount are on by default. Show total qty is off by default.

Q: Can I show the tax rate without the tax amount (or vice versa)?
A: Yes. Each field is independent. You can enable one without the other depending on what level of tax detail you need on your invoices.

Q: Is the total quantity the same as the number of line items?
A: No. The total quantity is the sum of all quantities across line items. For example, an order with 3 line items (qty 1, qty 2, qty 3) shows a total quantity of 6, not 3.

Q: Does the per-item tax affect the tax total in the Order total section?
A: No. These are separate settings. The per-item tax columns show tax applied to each line item. The Order total section has its own tax display setting that shows the overall tax for the entire order.

Q: Can I change the tax column header label (e.g., from "Tax" to "VAT")?
A: Yes. Go to the Labels section in the Visual Editor and update the Tax and Tax amount label text to your preferred terminology.
