Upsell with Pareto Volume Discount on Shopify POS

Pareto now works inside Shopify POS, so your store staff can see your Quantity Break tiers at the register, upsell customers to the next tier, and apply the same discounts your online store gives.

What it does

The Pareto Volume Discount extension adds three things to Shopify POS:

• A tile on the smart grid. It shows the cart state at a glance, for example "3 discounts ready", "2 upsell chances" or "$214.50 applied". Tapping it opens the Pareto screen.
• A Volume discount block on product pages. Open any product that has an active Quantity Break or One Discount campaign and the full tier table is listed, for example "Buy 3+ · $11.96/ea · -20%". The tier the cart already qualifies for is tagged "current" or "applied", and the block shows how many units are already in the cart.
• A "View Pareto offer" action on cart line items. Tap a line in the cart to see that product's offers, the next tier, and an Apply button.

The extension works on both POS Pro and POS Lite, with one difference:

• POS Pro: Shopify applies your Pareto discounts automatically. The extension shows what is already applied and what the customer could get next.
• POS Lite: Shopify does not run automatic discounts, so the cart would normally be sold at full price. Pareto calculates the same discount your online store would give and staff apply it from the Pareto screen in one tap.

How to set it up

The extension does not appear by itself after installing Pareto. You need to add the Pareto tile to your smart grid once. There are two ways to do it.

Option 1: From the Shopify admin (all locations)

Use this if you have several locations and want the same smart grid everywhere.

1. In your Shopify admin, go to Sales channels > Point of Sale.
2. In the Customize the in-store experience section, click Edit next to POS app.
3. In the Smart grid section, choose the smart grid template you use, then click Add tile.
4. Click Embedded Apps and select Pareto Volume Discount.
5. Click Save.
6. Back in the Point of Sale channel, click Edit Point of Sale, open the Apps section in the editor menu bar, and turn on the Pareto Volume Discount extension for the product details and cart line item surfaces. Click Save.

Option 2: From the Shopify POS app (this location only)

Use this to set up a single device quickly. You need to be the store owner or have the Customize smart grid staff permission.

1. On the POS home screen, tap Add tile in the smart grid.
2. Select Pareto Volume Discount from the list of apps.
3. Tap Save.

After either option, open Shopify POS on your device. The Pareto tile appears on the home screen and the Volume discount block appears on product pages.

Your Pareto discount method must be set to Automatic (Pareto settings). Offers are not available on POS when Manual discount mode is on.

How staff use it at the register

1. Tap the Pareto Volume Discount tile on the home screen to open the Pareto screen.
2. Under Ready to apply, tap Apply all to add every qualifying discount to the cart in one go. The cart updates with the discounted prices and a toast confirms how much was saved.
3. Under Upsell opportunities, each row shows what to add to reach the next tier, how much more the customer pays and how much more they save. Tap Add N to add those units to the cart.
4. Under Order discount progress, the screen shows how much more the customer needs to spend to unlock an order level discount.
5. Under Applied, staff can review every Pareto discount currently on the cart, including discounts Shopify applied automatically.
6. You can also tap a cart line item and choose View Pareto offer to see that product's tiers, apply its discount, or add units to reach the next tier.

Important notes

• Pareto never overwrites an existing discount. If a line already has a discount from Shopify, a discount code or a manual staff discount, Pareto only displays it and does not apply another one.
• When the cart quantity changes, Pareto recalculates the tier and updates or removes the applied discount so the cart price always matches your campaign rules. A toast tells staff when a line moves to a different tier or no longer qualifies.
• Shopify POS allows only one cart level discount at a time. If the cart already has a cart discount, Pareto shows a Compare discounts option so staff can keep the current one or replace it with the Pareto order discount.
• Tier thresholds count all variants in the campaign scope combined, the same as your online store.
• Campaigns that target specific customers only apply once a customer is added to the cart.
• Not supported on POS: weight based pricing, order discounts that exclude some products, and offers priced in a currency different from the POS location.
• All amounts are shown in the currency of your POS session. Very large carts show offers for the first 250 lines only.
