Cross-sell sources
In Cartsaver → Settings → Cross-Sell, the app asks you to pick a source for the products shown to customers in the WhatsApp cross-sell message after a verified order. This is the most important decision for the feature: a good source lifts your conversion rate, a poor one makes customers ignore the message.
The three options
Section titled “The three options”1. Manual Selection
Section titled “1. Manual Selection”You hand-pick up to 10 products. Every customer who triggers cross-sell sees the same list.
Best for:
- Promoting seasonal items or high-margin SKUs.
- Launching a new product.
- Small catalogues where you know exactly what to feature.
Trade-off: customers may see a product they already bought. Cartsaver only filters duplicates automatically in Shopify Recommendations mode.
2. Collection
Section titled “2. Collection”You pick a Shopify collection, and Cartsaver randomly chooses up to 10 products from it for each customer.
Best for:
- Medium-sized catalogues.
- Automatic variety without manual work.
- Stores that already maintain collections like “Best sellers” or “On sale”.
3. Shopify Recommendations
Section titled “3. Shopify Recommendations”Cartsaver uses Shopify’s official product-recommendations engine to choose the most relevant items for the current order, in one of two intents:
- Related — similar items (same category, similar price). Great for showing alternative colours or sizes.
- Complementary — items that pair with the order (e.g. a phone case with a phone). Great for raising average order value.
Best for:
- Catalogues of 50+ products.
- Stores that want high-quality recommendations without manual curation.
How 10 products are distributed across line items
Section titled “How 10 products are distributed across line items”In Shopify Recommendations mode, if the order has 5 different products, Cartsaver distributes up to 10 recommendations with a cap of 2 per line item, skipping duplicates and products already in the cart.
Switching sources without losing settings
Section titled “Switching sources without losing settings”Cartsaver stores each source’s configuration independently. If you switch from Manual Selection to Collection and back, your original product picks are still there.
Final activation
Section titled “Final activation”After picking a source, make sure the main switch Enable Cross-Sell at the top of the page is on, then save.
Verify it works
Section titled “Verify it works”- In Settings → Cross-Sell, the main switch shows Enabled and the selected source name appears at the top (“Source: Manual Selection / Collection / Shopify Recommendations”).
- After placing and verifying a test order, you receive a WhatsApp message with product recommendations within minutes.
- In Cartsaver → Cross-Sell → Statistics, the “Messages sent” counter increases by 1 after each verified order.
