The Best Affiliate Networks for Merchants
Most merchants who join legacy affiliate networks pay 20-30% in platform overrides without guaranteed affiliate recruitment. You still have to source affiliates yourself. This article breaks down why expensive networks like ShareASale and Impact may not deliver ROI, and shows you the math behind building an in-house program instead.
The Hidden Costs of Legacy Affiliate Networks
Affiliate networks charge a percentage of commission, usually 20-30%. On top of that, you handle recruitment, support, and payment processing. The network itself does not fill your affiliate roster.
Impact charges 30% on all commissions. ShareASale takes 20-25%. Commission Junction (CJ) ranges from 20-35%. These are your baseline costs before any affiliate joins your program.
What you actually get for these fees:
- A dashboard to manage affiliates
- Payment processing infrastructure
- Some basic fraud detection
- Network-wide affiliate access (if they decide to join your program)
What you don't get:
- Guaranteed affiliate recruitment
- Active sourcing of high-performing publishers
- Direct relationships with top-tier affiliates
- Control over commission rates or partner terms
Most merchants discover this gap within 6 months. They sign the network contract, build a dashboard, then wait for affiliates to apply. Few do.
The Cost Comparison: Network vs In-House
Here's a real scenario. You generate $100,000 in affiliate sales monthly.
Using a Legacy Network (Impact/ShareASale)
Commission paid to affiliates: $10,000 (10% standard) Network override (30% of commissions): $3,000 Payment processing fees: $500 Total cost: $13,500 Your net from affiliate channel: $86,500
Using In-House Software + Direct Recruitment
Commission paid to affiliates: $10,000 Software cost (mid-tier SaaS): $500-800/month Payment processing: $300-500 Staff time (part-time recruitment): $1,000-2,000/month Total cost: $12,000-13,500 Your net from affiliate channel: $87,000+
The difference narrows when you account for staff time. But here's the key difference: with in-house, you own the affiliate relationships. You control commission rates. You can negotiate exclusive terms with top performers. Networks don't allow this.
Top Affiliate Networks for Merchants (Ranked by Use Case)
Network Option 1: ShareASale
Best for: Merchants with $500K+ annual affiliate revenue Cost: 20-25% override Affiliate pool: 40,000+ Support: Dedicated account management at higher tiers
ShareASale works if you already have affiliate relationships or you're willing to invest heavily in recruitment. The network attracts established publishers. New or niche merchants typically see low organic application rates.
Network Option 2: Impact
Best for: Enterprise merchants ($1M+ affiliate revenue) Cost: 30% override (negotiable at scale) Affiliate pool: 100,000+ Support: Full-service partner management
Impact positions itself as a managed service. They take a larger cut but assign people to help with recruitment and optimization. This matters only if you have the budget to justify it.
Network Option 3: Commission Junction (CJ)
Best for: Established brands with existing affiliate networks Cost: 20-35% override Affiliate pool: 50,000+ Support: Tiered based on volume
CJ is the middle ground between ShareASale and Impact. It works best when you already have publisher relationships or deep pockets for marketing spend.
In-House Option 1: Refersion
Best for: E-commerce merchants under $2M affiliate revenue Cost: $99-299/month + 5% commission fee (optional) Setup time: 1-2 weeks Affiliate pool: You recruit directly
Refersion is built for Shopify stores. The tracking is solid. The real work is finding affiliates. This is where most merchants fail.
In-House Option 2: LeadDyno
Best for: SaaS and B2B merchants Cost: $249-999/month Setup time: 2-3 weeks Affiliate pool: You recruit directly
LeadDyno handles complex commission structures and multi-tier payouts. Better for recurring revenue models.
Why Merchants Choose In-House Programs
In-house programs scale affiliate revenue faster because you control recruitment. You don't compete with thousands of other brands for the same pool of network affiliates.
Specific advantages:
Direct relationship building. You contact top publishers directly. You negotiate exclusive rates. You build rapport. Networks don't allow this.
Commission flexibility. You offer 5% to weak performers and 20% to top tier. Networks force uniform rates or tiered structures that don't reward your best partners.
Faster payment and support. You pay affiliates how you want, when you want. You can offer weekly payouts or real-time incentives. Networks batch payments monthly.
Data ownership. You keep all affiliate, referral, and customer data. Networks control this. If you leave, you lose your affiliate list.
Cost at scale. At $500K+ monthly affiliate revenue, in-house costs drop to 2-5% total while networks keep taking 20-30%.
The Real Bottleneck: Finding Affiliates
Software is not the problem. Plenty of platforms track affiliate sales well. The problem is finding affiliates worth recruiting.
Most merchants make this mistake: they build a program and wait for affiliates to apply. Few do.
Successful programs actively source affiliates. You find:
- Influencers in your niche
- Bloggers covering your industry
- YouTube creators with relevant audiences
- Newsletter owners with engaged subscribers
- Industry publications and comparison sites
These publishers are not browsing your network for new programs. You have to find them, contact them directly, and give them reason to join.
This is where most in-house programs fail. Merchants underestimate the work required. They need a way to identify and contact these affiliates at scale.
How to Build an Affiliate Program Without Expensive Networks
Step 1: Choose Your Software
Pick one of these based on your business model:
- Refersion (e-commerce)
- LeadDyno (SaaS/B2B)
- Tapfiliate (multi-vendor)
- Ambassador (influencer-focused)
Budget $300-1,000/month for solid, mid-tier software.
Step 2: Set Commission Rates
Don't copy what networks suggest. Set rates based on your customer lifetime value (CLV) and average order value (AOV).
If CLV is $500, paying 10-15% is defensible. If CLV is $50, you need lower rates or higher volume.
Example commission structure:
Performance tier: 0-50 referrals = 5% Performance tier: 51-200 referrals = 10% Performance tier: 200+ referrals = 15%
Exclusive partners (top 5-10 affiliates): negotiate custom rates
Step 3: Recruit Affiliates Directly
This is the work. You have three options:
Option A: Manual outreach. Spend 10-15 hours weekly finding and contacting potential affiliates. Low cost, slow scaling.
Option B: Hire a part-time recruiter. $2,000-3,000/month. Faster but requires good training.
Option C: Use affiliate discovery tools to identify high-intent publishers already promoting competitors, then contact them. Fastest method.
Step 4: Manage Relationships
Once recruited, keep top performers engaged:
- Monthly check-ins to discuss performance
- Exclusive offers or commission boosts for top tier
- Monthly reporting with actionable data
- Support resources (creative assets, landing page copy)
- Quarterly bonuses for growth
Networks automate this poorly. In-house allows real relationship management.

Frequently Asked Questions
Q: Do I have to choose between networks and in-house?
A: No. Many merchants run both. They use networks to access a broad affiliate pool cheaply, but build in-house programs for their best partners. This gives you the safety net of network affiliates while investing in direct relationships.
Q: How long does it take to recruit enough affiliates for an in-house program?
A: If you recruit manually, expect 3-6 months to get 20-30 active affiliates. If you use discovery tools or hire a recruiter, 1-2 months is realistic. The bottleneck is always finding the right publishers.
Q: What if no one applies to my program?
A: Most merchants experience this in the first 2-3 months. Your job is to find affiliates, not wait for them. Look for publishers already in your space. Contact them directly. Offer a rate high enough that it's worth their time.
Q: Are network-only affiliates worth the override cost?
A: Network-wide affiliates work if you have high margins and large transaction volumes. For most merchants, the best performers are those you recruit directly because you can offer custom terms.
Q: What happens if I leave a network?
A: You lose access to that affiliate pool. You keep the sales data from your program but not the publisher contact information. This is why ownership matters for long-term growth.
