The best Shopify referral apps turn your existing customers into a free acquisition channel — no ad spend required. Paid ads keep getting more expensive every quarter, but your happiest customers are already telling friends about your store. You're just not tracking it or rewarding it.

That's what referral and affiliate apps fix. They turn word-of-mouth into a measurable, scalable sales channel. The Shopify App Store has dozens of options, though, and most merchants pick the wrong one because they confuse referral programs with affiliate programs. They're not the same thing. The app you need depends on which one you're actually building.

What's the Difference Between Referral and Affiliate Programs?

A referral program turns existing customers into advocates. They share a link with friends and family — people they actually know — and earn a reward when someone buys. Rewards are usually store credits, discounts, or free products. The relationship is personal.

An affiliate program recruits third-party promoters — bloggers, influencers, TikTok creators, review sites — who drive traffic through their content. They don't need to be customers. They earn cash commissions on every sale they generate. The relationship is transactional.

Get this distinction clear before you install anything. It'll save you from paying for features you don't need.

Some apps handle both. Others specialize in one. Here's what to look for based on your situation:

You want customers sharing with friends → referral-focused app

You want creators and influencers promoting your products → affiliate-focused app

You want both → an all-in-one app that does referral + affiliate (most of the apps below)

The 7 Best Shopify Referral and Affiliate Apps

Every app below was verified on the Shopify App Store in April 2026. Ratings, pricing, and features reflect what's live right now — not what a marketing page claims.

1. UpPromote — Best All-Around for Most Stores

Rating: 4.9/5 (3,200+ reviews) · Pricing: Free plan available, paid plans from $29.99/month · Installs: 60,000+ stores

UpPromote covers both affiliate and referral programs in a single app. You can recruit affiliates through a marketplace, create referral links for existing customers, set up multi-tier commissions, and track everything from one dashboard. The free plan handles up to 200 affiliate orders per month, which is enough for stores just getting started.

What makes UpPromote stand out is the onboarding. Most affiliate apps dump you into a blank dashboard and expect you to figure it out. UpPromote walks you through setting up your first program in under 15 minutes. The affiliate portal is clean enough that your partners won't need a tutorial either.

Best for: Stores that want referral + affiliate in one app and don't want to fight the learning curve.

Watch out for: Pricing adds up if you're running multiple programs at scale. The Professional plan at $89.99/month is where most growing stores land.

2. ReferralCandy — Best for Pure Referral Programs

Rating: 4.9/5 · Pricing: From $29/month + 10.5% success fee (Basic), lower fees on higher plans · Free trial: 14 days

ReferralCandy has been in the referral game longer than most competitors. It does one thing well: it automates the refer-a-friend loop. A customer buys, gets a referral link, shares it, and both the referrer and the new customer get rewarded. The whole flow runs without you touching it after setup.

The catch is the commission-based pricing. On the Basic plan, you pay $29/month plus 10.5% of every referral sale. That's fine when you're doing low volume, but it gets expensive fast. The Scale plan ($249/month + 1.5% fee) is more cost-effective once you're generating significant referral revenue.

Best for: Established stores that want a polished, set-and-forget referral program. If you're not interested in building an affiliate network with external partners, ReferralCandy keeps things simple.

Watch out for: The percentage-based fees. Calculate your expected referral revenue before committing — a flat-fee app might save you hundreds per month at higher volumes.

3. GoAffPro — Best Free Option for Affiliate Programs

Rating: 4.8/5 (1,800+ reviews) · Pricing: Free plan (unlimited affiliates), Premium $29/month

GoAffPro's free plan is surprisingly complete. You get unlimited affiliates, a branded affiliate portal, analytics, post-checkout popups for affiliate recruitment, and welcome emails. Most other apps lock at least half of those features behind a paywall.

The premium plan at $29/month adds multi-level marketing structures, advanced analytics, and more customization. But for a store that just needs a working affiliate program without spending anything upfront, the free plan covers it.

Best for: Budget-conscious stores that want to launch an affiliate program at zero cost. Also good for stores that need multi-level (MLM-style) commission structures.

Watch out for: The interface isn't as polished as UpPromote or ReferralCandy. You'll trade design for savings.

4. BixGrow — Best Budget All-in-One

Rating: 4.9/5 (1,200+ reviews) · Pricing: Free plan available (up to 30 affiliates), paid plans scale up · Installs: 29,000+ stores

BixGrow combines affiliate and referral programs at a lower price point than UpPromote. The free plan limits you to 30 affiliates, but includes referral program features, auto-generated coupon codes, and multi-language support.

Where BixGrow shines is for stores selling across TikTok, Instagram, and YouTube. It's built for social commerce-style affiliate marketing — think micro-influencers with small but engaged audiences. The auto-apply coupon at checkout (available on the Scale plan) removes a common friction point where customers forget to enter the affiliate's code.

Best for: Small to mid-sized stores that want affiliate + referral without paying $30+/month from day one.

Watch out for: The 30-affiliate limit on the free plan is tight. You'll outgrow it quickly if your program gains traction.

5. Social Snowball — Best for Influencer-Heavy Brands

Rating: 4.9/5 · Pricing: From $99/month + 3% of affiliate revenue (Snow Day plan)

Social Snowball takes a different approach. Instead of waiting for affiliates to apply, it turns every customer into a potential affiliate at the point of purchase. Right after checkout, customers see an offer to become an affiliate — no separate sign-up flow, no waiting for approval.

This works especially well for DTC brands running influencer programs. The app tracks TikTok and Instagram creators, handles store credit payouts (which cost you less than cash commissions), and provides accurate influencer ROI tracking. If you're already spending on creator partnerships, Social Snowball helps you measure what's actually converting.

Best for: Brands doing $50K+/month that run influencer programs and want to automate affiliate recruitment from their existing customer base.

Watch out for: Pricing starts at $99/month plus 3% of affiliate revenue. This isn't for stores testing the waters — it's for stores ready to invest in word-of-mouth as a real channel.

6. Smile.io — Best for Referrals Inside a Loyalty Program

Rating: 4.8/5 · Pricing: Free plan available (under 200 orders/month), Starter $49/month, Growth $199/month

Smile.io isn't primarily a referral app — it's a loyalty platform that includes referrals as one of three modules (alongside points and VIP tiers). If you're already thinking about building a loyalty program and want referrals baked in, Smile.io handles both without adding a second app to your stack.

The referral feature lets customers share links across social media, email, and direct messages. Both the referrer and the friend get rewarded. It's clean and straightforward, but it doesn't offer the depth of a dedicated referral app — no multi-tier commissions, no affiliate recruitment tools.

Best for: Stores that want loyalty points, VIP tiers, and referrals in a single app. If referrals are one piece of a broader retention strategy, Smile.io makes sense.

Watch out for: The referral features alone don't justify Smile.io's price. You're paying for the full loyalty suite. If you only need referrals, a dedicated app is more cost-effective.

7. Affiliatly — Most Affordable Paid Option

Rating: 4.3/5 · Pricing: From $16/month (up to 50 affiliates) · Free trial: 90 days

Affiliatly is the cheapest paid affiliate app on this list, and it comes with a 90-day free trial — the longest of any app here. The dashboard is straightforward: you create affiliate links, set commission rates, track sales, and process payouts. No bells, no whistles.

The lower rating (4.3 vs. 4.8+ for competitors) reflects a more basic feature set and less polished interface. But for stores that want a simple affiliate program without free-plan limitations, the pricing is hard to beat. The Pro Unlimited plan at $129/month gives you unlimited affiliates, orders, and payouts.

Best for: Stores that want a straightforward, low-cost affiliate program and don't need advanced features like multi-tier commissions or influencer tracking.

Watch out for: Fewer integrations and less active development compared to UpPromote or BixGrow. The 90-day trial gives you plenty of time to test before committing.

How to Pick the Right App for Your Store

Skip the feature comparison spreadsheet. Answer these three questions instead:

1. Referral program, affiliate program, or both? Referrals only → ReferralCandy or Smile.io. Affiliates only → GoAffPro's free plan. Both → UpPromote or BixGrow.

2. What's your monthly budget? $0 → GoAffPro or BixGrow free plans. Under $30/month → Affiliatly or UpPromote free tier. $30–100/month → UpPromote or ReferralCandy. $100+/month → Social Snowball.

3. How many affiliates do you expect? Free plans cap at 30–200 affiliates or orders. If you're recruiting aggressively, you'll hit those limits within months.

Set Up Your Program Before You Install

The app you pick matters less than the program you design. Before installing anything, decide these four things:

Commission structure: Percentage of sale (10–20% is typical for affiliates) or flat fee? Store credit or cash?

Cookie duration: How long after someone clicks a referral link does the affiliate still get credit? 30 days is standard. Shorter windows hurt your affiliates' motivation.

Reward for both sides: Referral programs work best when both the referrer and the friend get something. A 10% discount for both is a common starting point.

Minimum payout threshold: Don't set it too high. If affiliates need to generate $100 before they see any money, most will quit before they get there. $25 keeps people engaged.

Get these decisions made first, then pick the app that supports your structure at a price you can sustain. Every app on this list offers a free plan or trial — install one, run it for 30 days, and look at the data before committing to a paid plan.
