Configure product offers

Quick start

To get started, follow these steps:

1. Sign in to the FastSpring app.
2. Go to Catalog > choose Products, Bundles, or Subscriptions.
3. From that list, select the item you want to add offers to. The details page opens, showing the Related Offers section.

Next, scroll down to the Create a cross-sell offer or Create an upsell offer section to set up your offer.

Create a cross-sell offer

Use cross-sells to recommend complementary products when a customer adds an item to their cart.

1. On the details page, open the Related Offers section and click Add > Product Offer.
2. Select Cross-sell as the Offer Type.
3. (Optional) In Display, enter a customer-facing message.

   Use the language dropdown to add translations.

4. Choose a Placement number from the dropdown to control the order in which offers appear at checkout.

   This only applies if you configure two or more options for the product.

5. In the Products field, start typing the name of the product you want to offer.

   Tip: To offer a special price on the cross-sell, first create a private product variation for that item, then select it here.

6. (Optional) Select Preselected to auto-add the cross-sell to the cart.
7. Click Save.

Once saved, the cross-sell will appear on your web checkout each time a customer selects the associated product.

Recommendations

• Only cross-sell products that are already public in your store.
• Keep cross-sells under 50% of the driving product's price.
• Limit the number of cross-sells to avoid overwhelming customers.

Create an upsell offer

Use upsells to encourage customers to choose a higher-value product at checkout.

1. On the details page, open the Related Offers section and click Add > Product Offer.
2. Select Upsell as the Offer Type.
3. (Optional) Enter a Display message.
4. Choose a Placement number from the dropdown to control the order in which offers appear at checkout.

   This only applies if you configure two or more options for the product.

5. In Products, select the upsell product.
6. Click Save.

Once saved, the upsell will appear on your web checkout each time a customer selects the associated product.

Recommendations
