# Using Dollarlabs Ultimate Discounts With Downpay (Partial Payments) This guide walks you through how to create two common discount setups when using **Downpay partial payment products** with **DollarLabs Ultimate Discounts**: 1. **Buy X → Get Y at 10% off — 1:1 scaling** 2. **Apply discounts only when the product is purchased *****in full***** (no selling plan)** These setups are not supported by Shopify’s native discounts, but they work seamlessly with our discount engine. {% embed url="" %} *** ### **Before You Begin** Make sure your Downpay products are already configured.\ If not, refer to Downpay’s [setup guides](https://docs.downpay.app/en/article/quick-start-1dtrqcp/) or contact their team. *** ## **1. Buy X, Get Y Discount (1:1 Matched Quantity)** #### **Goal** When a customer buys: * **1 unit of “Downpay 50%”**,\ they should get * **1 unit of “Downpay 25%” at 10% off** This must scale **1:1**.\ If the customer buys 3 units of 50%, then up to 3 units of 25% get 10% off. *** ### **Step-by-Step Setup** #### **Step 1: Create a Unified Discount** * Go to **Ultimate Discounts → Unified Discounts → Create → General Discount** * Name it: **Buy X Get Y** * Select **Percentage → 10% off** *** #### **Step 2: Create Cart Groups** You need two cart groups: 1. **Buy X Group** * Add the product: *Downpay 50%* 2. **Get Y Group** * Add the product: *Downpay 25%* *** #### **Step 3: Add the Trigger Condition** Set rule: > “Discount applies only if the customer has **at least 1 unit** from the **Buy X** group in the cart.” This ensures the Get Y discount only activates when Buy X is present. *** #### **Step 4: Set the Discount Target** * Set **Target = Get Y group**\ This tells the discount engine which items should receive 10% off. *** #### **Step 5: Enable 1:1 Matching** By default, Shopify will discount *all* units in the Get Y group.\ To prevent this: 1. Click the **settings toggle** next to the discount percentage. 2. Enable **Max Quantity**. 3. Set matching to **Dynamic**. 4. Set maximum limit source: > **Cart Group = Buy X → Quantity Sum** This means: * If the cart has 1 unit of Buy X, only 1 unit of Get Y gets 10% off. * If the cart has 3 units of Buy X, up to 3 units of Get Y get 10% off. *** ### **How It Works in the Cart** * 1× Downpay 50% + 1× Downpay 25% → 10% discount applies * If customer adds more 25% products without increasing 50%, extra units become full price\ (the app splits line items automatically) *** ## **2. Discount Only for Full-Payment Purchases (No Selling Plan)** #### **Goal** Apply a discount only when the product is purchased **without a selling plan** (i.e., full payment).\ If the product is purchased as a partial payment (Downpay plan), **no discount applies**. Perfect for: * Incentivizing full-price purchases * Avoiding discount stacking with partial payments *** ### **Step-by-Step Setup** #### **Step 1: Duplicate the Previous Discount** * Disable the earlier BXGY * Click **Duplicate** to reuse the structure * Rename it: **Buy in Full Discount** *** #### **Step 2: Remove the Get Y Group** This discount applies only to the **same product** when purchased in full. *** #### **Step 3: Add Rule: “Purchased without Selling Plan”** Add conditions: 1. **Product ID is...** (select the desired product) 2. **Selling Plan = None**\ Meaning: the customer selected "Buy in Full" *** #### **Step 4: Set Discount** * Choose discount type (example: **20% off**) * Set discount target to **Buy X group** *** ### **How It Works in the Cart** * Cart contains partial payment versions → **No discount** * Customer adds the “Pay in Full” version → **Only that product gets the discount** * Partial payment and full payment versions are treated independently *** ## **Summary** #### **Discount 1: Buy X Get Y (1:1 Match)** * Perfect for pairing partial payment products * Ensures discount is proportional to the paid deposit product * Automatic line item splitting ensures accurate enforcement #### **Discount 2: Discount Only for Full-Payment Items** * Encourages full payment * Prevents unwanted discounting on Downpay partial payment plans * Works based on Selling Plan logic Both discount setups are impossible using Shopify’s default discount tools — but DollarLabs Ultimate Discounts makes them easy and reliable. *** ## **Need Help?** If you want help replicating these setups or configuring more advanced rules (limits, exclusions, multi-tier logic, etc.), reach out to us via: * In-app chat * We're always happy to help you build the exact discount logic your store needs. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
