Quantity Edits allows customers to increase the quantity of line items already in their order and pay for the additional products in one click. For example, a customer who ordered one hoodie can bump it to two and pay the difference instantly, no support ticket required.
You'll find this at App Blocks > Quantity Edits.
This block has a single toggle to enable or disable quantity increases.
Setting | Description |
Allow customers to increase product quantities | When enabled, customers can increase the quantity of any line item in their order and pay you for the additional products in one click. For example, a customer who bought 1x protein powder can increase it to 3x and pay for the extra 2 units immediately. |
💡 Tip: This is a great revenue driver. Customers who forgot to add extras or want to stock up can do so without placing a separate order, which means more revenue per order and lower shipping costs for you.
When a customer completes their purchase, the order editing block appears on the thank you page and order status page. If Quantity Edits is enabled, they'll see the option to increase the quantity on any product in their order. The flow is simple:
Customer sees the order editing block on their thank you page or order status page.
They select the item they want more of and increase the quantity (e.g. from 1 to 3).
They're prompted to pay the difference for the additional items.
Payment is captured in one click and the order is updated in Shopify.
✅ Example: A customer orders 1x candle ($35). Right after checkout, they realise they want two more as gifts. They use the order editing block on their thank you page, increase the quantity to 3, and pay $70 for the extra candles. The order is updated in Shopify with the new quantity and payment, no new order created.
This block controls increasing quantities only. If you also want customers to be able to decrease quantities (remove items or reduce quantities), you'll need to enable Order Downgrades in your settings. Order Downgrades handles all scenarios where the order value goes down, including quantity reductions.
You can customise every text label your customers see when editing quantities. Click the Translate button in the top-right corner of the Quantity Edits page to open the translations panel. Change any default text to match your brand's tone of voice, and set different translations for each language your store supports.

• A boutique changes "Save" to "Confirm changes" to make the action feel more deliberate.
• A premium brand customises the loading messages to "Updating your order...", "Almost there...", and "All done!" to match their friendly tone.
