Selling online isn’t just about listing products—it’s about crafting an experience and optimizing your catalog to drive revenue. One of the most effective ways to boost order value and improve customer satisfaction is to sell complementary products. Whether you’re in fashion, home decor, electronics, or wellness, offering relevant add-ons can significantly elevate your store’s success.
In this comprehensive Syncee guide, we’ll show you how to strategically sell complementary products, test new ideas with dropshipping, and scale your product selection without upfront risk. If you’re looking to increase your revenue and enhance customer loyalty, this guide is for you.
Why You Should Sell Complementary Products
If you’re not already offering add-ons or related items, you’re missing out on untapped revenue. When you sell complementary products, you’re encouraging customers to buy more in a single transaction. It’s one of the most powerful techniques to increase average order value (AOV).
For example:
- A shopper buying a yoga mat may also purchase a water bottle and resistance bands.
- Someone adding a laptop to their cart could also be interested in a case, mouse, or keyboard cover.
These combinations feel natural to shoppers—and that means more conversions for you.
Advantages of Complementary Sales
With dropshipping, adding and testing new product combinations is low-risk. There’s no need to purchase inventory in advance. This makes it easier than ever to sell complementary products tailored to your customers’ habits.
What Makes Dropshipping Ideal?
- No inventory storage needed
- Fast product testing and validation
- Easy removal of slow-selling items
- No capital tied up in stock
With Syncee, you can import quality products into your online store in seconds from a global pool of pre-vetted suppliers. This flexibility empowers you to experiment with bundles and discover which items sell well together.
How to Identify Complementary Products
Understanding your customers’ buying habits is key to success. When planning to sell complementary products, start by analyzing what your customers typically buy and consider what naturally goes with it.
1. Analyze Your Current Catalog
Use data to understand your bestsellers. What pairs well with them? Look at:
- Purchase history
- Abandoned cart patterns
- Product categories with cross-over appeal
2. Browse Syncee’s Product Recommendations
Syncee’s product search engine and curated collections make it easy to find matching products. For example, if you’re selling skin care, Syncee helps you discover facial rollers, headbands, and other beauty accessories that customers might love. Look for products in chosen categories like skincare and find items.
Strategies to Sell Complementary Products
Once you’ve identified add-on items, the next step is implementing them in your store. Here are proven ways to effectively sell complementary products found on Syncee:
Create Product Bundles
Bundle frequently bought-together items into kits in your online store. For instance:
- Pet grooming kits
- Kitchen essentials sets
- Skincare bundles (cleanser + toner + serum)
Find products on Syncee and use other useful apps for bundle selling.
Highlight Add-Ons in Product Descriptions
In your product listings, suggest complementary items. Example: “Pair this dress with our matching necklace or heels for a complete look.”
Add Syncee Products with Smart Pricing Rules
Use Syncee’s automated pricing and margin tools to ensure your complementary products are profitable. Set different rules for different product groups by creating more import lists to reflect added value.
Use Shopify Apps to Support Cross-Sells
If you’re using Shopify with Syncee, integrate upsell or cross-sell apps that highlight complementary items during checkout or on product pages.
Example Niches

3. Home Decor

Best Practices to Sell Effectively
To truly succeed in using this strategy, here are some best practices to help you sell more and build a better store:
Use Visuals Wisely
Show complementary items side by side in product photos, carousel images, or lifestyle shots.
Include Clear CTAs
Use calls-to-action like:
- “Complete the set”
- “Get the matching item”
- “Upgrade your kit”
Track Bundle Performance
Monitor which bundles or add-on recommendations convert best. Use Shopify or Google Analytics to refine your strategy.
Seasonal and Thematic Promotions
Tie your complementary items into seasonal promotions. For example, offer “Summer Essentials” or “Holiday Gift Packs” that combine multiple items.
