Referral and affiliate programs are often grouped together because both offer rewards for bringing in customers. However, it’s important to note that they operate in different ways.
A referral program typically starts with existing customers who have already purchased and trust the product. They usually recommend it to someone they know personally. On the other hand, an affiliate program begins with distribution partners, such as creators, publishers, or community operators, who have an audience to promote the product to. While both are based on trust, the approach varies.
So, when should merchants consider adding an affiliate program on top of a referral program?
We analyzed a random selection of Shopify programs on ReferralCandy that generated sales between June 1, 2025, and May 31, 2026. The question we asked ourselves was: does adding an affiliate program after establishing a referral program increase the benefits?
Referral + Affiliate
- 55.2% of successful programs had a revenue share of 5% or more
- The median referral revenue share was 5.6%
Referral Only
- 30.5% of successful programs had a revenue share of 5% or more
- The median referral revenue share was 3.3%
The Impact
- Programs with both referral and affiliate were 1.8 times more likely to reach a revenue share of 5% or more
- They had a 68% higher median revenue share compared to referral-only programs
- Affiliate programs are most effective after the referral program has proven successful
Affiliate Programs Are More Than Just Campaigns
Looking at the overall success rate of programs may not be the best way to evaluate the benefits. In most cases, merchants should not rush to add an affiliate program from day one. The key question is how adding an affiliate program impacts revenue once the referral program is already generating measurable results.
Among successful programs, those with both referral and affiliate components were 1.8 times more likely to achieve a revenue share of 5% or more. Their median referral revenue share was 5.6%, compared to 3.3% for referral-only programs. Additionally, their median referral order rate was higher at 6.1% versus 3.5%.
Achieving a 5% revenue share is significant. For a store with $1 million in annual revenue, this would translate to $50,000 in revenue attributed to referrals. Not every store may reach this level, but the key takeaway is that affiliate programs are most beneficial once the referral system is already effective.
This indicates that the benefit is not just about running more campaigns. Affiliate programs attract a different audience compared to referral programs. While referral programs rely on customers sharing with people they know, affiliate programs incentivize partners to promote the brand to a wider audience.
Adding Affiliate Programs When Audience Dynamics Change
Merchants should not introduce an affiliate program simply because they have a referral campaign in place. If the primary advocates are regular customers making personal recommendations, starting with a referral program is more straightforward, easier to explain, and closer to the customer relationship.
An affiliate program becomes relevant when the brand has partners who can reach a broader audience beyond their immediate circle. These partners could be creators, niche publishers, ambassadors, consultants, community leaders, or customers who consistently refer and seek additional benefits. At this stage, the program requires different strategies, such as trackable links, commission-based rewards, partner management, and incentives for ongoing promotion.
The data validates this approach. Programs with a dedicated affiliate component outperformed referral-only programs in terms of success metrics. Simply running more non-affiliate campaigns did not yield the same results.
Start with Referral, Add Affiliate When Ready
For most merchants, beginning with a referral program is the ideal starting point. It demonstrates that customers are willing to share, the offer is compelling, and word-of-mouth can lead to measurable revenue. Once the referral program is established, adding an affiliate program extends the reach to partners who engage more actively in promoting the brand.
Timing is crucial. Introducing an affiliate program too early can result in managing another ineffective campaign. However, when there is evidence that customers are enthusiastic about discussing the brand, adding an affiliate program creates a secondary growth opportunity based on the existing trust and success of the referral program.
The focus should not be on complexity but on expanding distribution. When customers or partners can introduce multiple individuals to the brand simultaneously, an affiliate program becomes a valuable addition alongside the referral program.
