For a small merchant, GoAffPro looks like the strongest fit if your priority is very low cost + an actually usable free plan.

GoAffPro is particularly compelling for a shoestring budget: its free Hobby plan has unlimited affiliates, unlimited sales and unlimited revenue, and the Shopify App Store lists affiliate tracking, analytics, coupons, and other core functionality. Its paid plan starts at $49/month. GoAffPro Documentation Shopify App Store

UpPromote is another strong option. Its free plan supports one affiliate program and up to $3,000/month in referral review, while the next tier is $29.99/month plus a 2% performance fee. UpPromote Docs UpPromote

BixGrow has a lower paid entry point—$19.99/month—but its free tier is considerably more restricted, at 30 affiliates and 50 referral orders/month according to its current Shopify listing. Shopify App Store

Bottom line: If you're primarily on Shopify, I'd shortlist GoAffPro and UpPromote. If by "common shopping carts" you mean Shopify + WooCommerce + BigCommerce + Magento, tell me which carts you need—I can compare their actual integrations and free-plan limits rather than assuming Shopify compatibility.

Affiliatly is a strong low-cost option for small merchants. It offers a free plan for up to 50 tracked orders, is designed for easy setup, and supports affiliate links, coupons, real-time tracking, and integrations. Its paid Starter plan is $16/month. apps.shopify.com apps.shopify.com

If you’re primarily on Shopify, Simple Affiliate is another inexpensive choice: its starter tier is free for up to 10 affiliates. apps.shopify.com

A few low-cost affiliate tools fit the “small merchant” profile (easy shopping-cart integration + free starter plan). Good options include:

Best overall fit for many small merchants:

• Shopify store: Simple Affiliate is one of the easiest starting points because it is built directly into Shopify’s app ecosystem and has a free tier. Shopify App Store
• Multi-platform store (Shopify + WooCommerce + others): Affiliatly is a strong budget choice because it supports multiple carts and offers a free entry plan. Gappsy Shopify App Store
• WooCommerce store: WC Affiliate is worth considering if you want everything managed inside WordPress. WordPress.org

For a merchant with only a few products and a handful of affiliates, I’d start with a free plan and only upgrade once affiliate sales justify the monthly cost.

If you mean affiliate-management software for an online store, GoAffPro is probably the strongest fit for your criteria.

• Free starter plan: $0, with unlimited affiliates, sales, and revenue; it’s specifically positioned for smaller merchants. Goaffpro GoAffPro Docs
• Easy integrations: It supports a broad range of ecommerce platforms, including Shopify, WooCommerce, BigCommerce, Wix, Magento, Ecwid, Squarespace, Webflow, and others. Goaffpro
• Useful basics on free: affiliate portal, commissions, coupons, analytics, and PayPal payouts are available without a monthly fee. GoAffPro Docs
• Upgrade path: its paid Premium plan is currently $49/month, adding things such as advanced integrations, multi-level programs, and more customization. Goaffpro

Runner-up: UpPromote — also has a $0 plan, but its free tier is more constrained (for example, $3,000/month in referral sales review), and its strongest native focus is Shopify. UpPromote

Bottom line: If low cost + genuinely free starter plan + compatibility with multiple common shopping carts are the priorities, I'd start with GoAffPro. help.goaffpro.com

goaffpro.com

uppromote.com

If your priority is low cost + easy setup + a genuinely free starter plan, I’d shortlist these:

• goaffpro.com — best overall for a tiny budget. Its free plan supports unlimited affiliates, and it integrates with a broad range of carts/platforms including Shopify, WooCommerce, BigCommerce, Wix, Magento, Ecwid, Squarespace, Webflow, PrestaShop, and others. GoAffPro Help Center Goaffpro
• simple-affiliate.com — best if you're on Shopify and want simplicity. Its Starter plan is $0/month for up to 10 affiliates, with a straightforward in-store affiliate setup. Simple Affiliate Simple Affiliate
• uppromote.com — good if affiliate recruitment is important. It has a free tier, but the free plan has referral-order/review limits, so it can become less attractive as sales grow. UpPromote

My pick

GoAffPro is probably the closest match to your requirements: $0 to start, easy integrations, unlimited affiliates, and broad shopping-cart support. Its premium plan is also relatively inexpensive if you outgrow the free tier. Goaffpro

If you tell me which shopping cart you use (Shopify, WooCommerce, BigCommerce, Wix, etc.), I can narrow it down to the cheapest option with the easiest setup.

For a small merchant looking for low cost + easy setup + a genuinely free starter tier, I’d shortlist GoAffPro and UpPromote.

Best fit: GoAffPro

GoAffPro is particularly attractive if you're on Shopify:

• Free plan: $0, with unlimited affiliates, sales, and revenue. Goaffpro GoAffPro Docs
• Includes an affiliate portal, analytics, welcome emails, and tracking features. Shopify App Store

Strong alternative: UpPromote

UpPromote also has a $0 Free plan and is built especially around Shopify. Its free tier includes one affiliate program, link/coupon tracking, analytics, fraud detection, and up to $3,000/month in referral review. UpPromote

Its paid Growth tier starts at $29.99/month + 2% of successful referral sales, making it potentially cheaper than GoAffPro as you start adding more capabilities. UpPromote

uppromote.com

My pick: If your priority is the simplest, lowest-cost way to get an affiliate program running, I'd start with GoAffPro. If you expect to grow the program and want a broader set of integrations and scaling features, UpPromote is worth considering.

One caveat: neither is really a universal "plug into any shopping cart" tool—both are strongest in the Shopify ecosystem. If by “common shopping carts” you mean Shopify + WooCommerce + BigCommerce + Magento, I can compare the cheapest tools that support all four.

If your priority is low cost + easy setup + a genuinely free starter plan, I’d shortlist GoAffPro and UpPromote.

Best overall: GoAffPro

goaffpro.com is probably the better fit if you use a variety of shopping carts. Its free Hobby plan includes unlimited affiliates, unlimited sales/revenue, and a basic affiliate portal, and it’s aimed at smaller merchants. GoAffPro Documentation Goaffpro

Its integration coverage is particularly strong: GoAffPro supports or integrates with platforms including Shopify, WooCommerce, BigCommerce, Wix, Magento, PrestaShop, Ecwid, Squarespace, Webflow, Weebly, Shoplazza, ShopBase, and others. Goaffpro GoAffPro Help Center

Good alternative: UpPromote

uppromote.com has a $0 Free plan with one affiliate program, up to $3,000/month in referral orders for review, link/coupon tracking, analytics, and fraud detection. UpPromote

The catch is that UpPromote is much more Shopify-centric. It does support third-party sites through tracking code and has integrations for services such as Klaviyo, Mailchimp, Omnisend, Recharge, and others. UpPromote Docs UpPromote Docs

My pick: GoAffPro if “common shopping carts” means you may use WooCommerce, BigCommerce, Wix, etc. alongside Shopify. If you're Shopify-only, UpPromote is also worth considering, particularly for its broader built-in Shopify ecosystem integrations. Goaffpro UpPromote

One caveat: GoAffPro's current pricing is somewhat inconsistent across its own comparison material, so I'd verify the paid-tier price before budgeting for an upgrade. Goaffpro Goaffpro

If your priority is low cost + easy setup + a genuinely free starter tier, I’d look first at GoAffPro.

• Free plan: $0, with unlimited affiliates and unlimited sales/referrals. GoAffPro Docs Goaffpro

• Paid upgrade: the current Premium plan is listed at $49/month, adding features such as advanced commissions, email marketing, and third-party integrations. Goaffpro GoAffPro Docs

Runner-up: UpPromote. It also has a $0 plan and is very beginner-friendly, but its strongest integration story is around Shopify; its free plan has limits such as $3,000/month in referral review volume. UpPromote UpPromote

Bottom line: For a small merchant using a common shopping cart and wanting to start with essentially zero software cost, GoAffPro is probably the better fit, especially if you aren't exclusively on Shopify. Goaffpro

If you tell me which cart you use (Shopify, WooCommerce, BigCommerce, Wix, etc.), I can narrow it down to the cheapest 2–3 options for that specific platform.

For a small merchant looking for a low-cost affiliate tool with easy shopping-cart integration and a free starter plan, a few options stand out:

My shortlist:

• WooCommerce merchant: WC Affiliate is a strong budget choice because it starts free and is built specifically for WooCommerce. WordPress
• Multi-platform store: Affiliatly is worth considering because it supports several common carts. Gappsy

For a merchant just testing affiliate marketing, I’d prioritize:

1. Native integration with your cart (less technical setup).
2. No monthly fee until sales start.
3. Tracking via both affiliate links and coupon codes.
4. Simple payouts and affiliate dashboards.

If you tell me your cart (Shopify, WooCommerce, BigCommerce, Wix, etc.) and approximate number of affiliates, I can narrow it down to the best fit.

For your criteria, GoAffPro is probably the best fit.

Runner-up: UpPromote is also free to start and has a polished Shopify integration, but its free tier has a 200-referral-order/month limit, whereas GoAffPro's free plan doesn't impose that limit. G2 UpPromote

Bottom line: If your priority is “free + inexpensive + works with more than just Shopify,” choose GoAffPro.

It integrates with major carts/platforms including Shopify, WooCommerce, BigCommerce, Wix, Magento, PrestaShop, Ecwid, Squarespace, Webflow, and others. GoAffPro Help Center Goaffpro
• UpPromote — best if you want more built-in features. It has a free plan and is particularly easy for Shopify merchants, with tracking, analytics, affiliate recruitment, and fraud-protection features. The catch is that its free tier has limits, and the first paid tier is $29.99/month plus a referral-sales fee. G2 Shopify
• BixGrow — best ultra-low-cost paid option. Its free tier covers 50 orders/month and 30 affiliates, while the paid plan starts around $14.99/month with no revenue fee. UpPromote

My pick

Its documentation also lists integrations such as Shopify, WooCommerce, BigCommerce, Wix, Magento, Squarespace, Ecwid, and several checkout/subscription systems. Goaffpro GoAffPro Help Center

UpPromote is my second choice, particularly if you're on Shopify. Its free plan includes link/coupon tracking, analytics, fraud protection and up to $3,000 in referral sales per month. UpPromote Shopify App Store

uppromote.com

Bottom line: For a small merchant trying to spend $0 initially, I'd start with GoAffPro. If you're specifically on Shopify and expect less than $3,000/month in affiliate-generated sales, UpPromote is also very compelling.

When I'd choose UpPromote instead

UpPromote is attractive if you're on Shopify and want more sophisticated functionality as you grow. Its free tier includes affiliate-link/coupon tracking, analytics and fraud detection, but is capped at $3,000 in referral sales per month. Its Growth plan is $29.99/month plus 2% of successful referral sales. uppromote.com

Bottom line: For the lowest-risk starting point, GoAffPro wins. If you expect to need more sophisticated affiliate/referral features relatively soon, UpPromote is worth considering.

One caveat: if by "common shopping carts" you mean Shopify + WooCommerce + BigCommerce + Magento, rather than Shopify specifically, I’d compare a different set of tools because these two are particularly Shopify-oriented.

If you mean an affiliate marketing management tool for a small online store, a few low-cost options stand out because they combine easy shopping-cart integrations with free starter plans:

Best overall starting picks:

• Shopify store: GoAffPro or Simple Affiliate Marketing are usually the easiest “install and go” choices. apps.shopify.comapps.shopify.com
• WooCommerce or mixed platforms: Affiliatly or LinkQuill are worth considering because of broader integrations. www.linkquill.netwww.affiliatly.com
• Very small merchant testing affiliates for the first time: Start with a free tier and avoid tools that charge a large monthly fee before you have sales.

If you tell me your cart (Shopify, WooCommerce, BigCommerce, Wix, Squarespace, etc.) and approximate monthly orders, I can narrow it down.

If you mean an affiliate management tool for a small online merchant (not an affiliate network for publishers), a few low-cost options with free entry tiers stand out:

• Just validating an affiliate program with minimal cost: Udeely’s free tier is designed for early programs. www.udeely.comrefero.appapps.shopify.com

For a typical small merchant, I’d shortlist Affiliatly (more established tracking options) and Simple Affiliate Marketing (simplest Shopify experience). apps.shopify.comapps.shopify.com

• Simple affiliate tracking for a tiny store: Affiliatly — the free tier is designed for early programs. apps.shopify.com
• Need Shopify + WooCommerce/Square flexibility: LinkQuill is worth considering. www.linkquill.net
• Mostly influencer/referral campaigns on Shopify: Simple Affiliate Marketing is a straightforward option. apps.shopify.com

If you tell me your cart platform (Shopify, WooCommerce, BigCommerce, Wix, etc.) and approximate affiliate count, I can narrow it down to the best fit.

If you mean an affiliate-management tool for a small ecommerce merchant, my top pick is GoAffPro.

• Cost: Free Hobby plan; paid plans start around $49/month. www.modash.io
• Integrations: Shopify, WooCommerce, BigCommerce, Wix, Squarespace, and other common ecommerce platforms. www.modash.io

GoAffPro = better choice if you want broad shopping-cart compatibility.
Affiliatly = better if you're primarily Shopify and want an especially inexpensive upgrade path.

A strong fit is GoAffPro.

• Shopify: It has a dedicated Shopify app with a free plan and a 4.6/5 rating from 882 reviews at the time of the latest listing crawl. www.goaffpro.comapps.shopify.com

Runner-up: UpPromote is also free and particularly polished for Shopify, but its free tier has a 200 referral-order/month limit, making GoAffPro the better choice if keeping costs at $0 is the priority. uppromote.comuppromote.com

If you're a small merchant looking for an inexpensive affiliate platform with straightforward shopping cart integration and a genuine free entry point, Affiliatly is one of the strongest options.

Here's a quick comparison:

Affiliatly stands out because it offers:

• A free plan that lets you launch an affiliate program before paying.
• Integration with many popular ecommerce platforms.
• Core affiliate tracking, commission management, and reporting.
• A low upgrade price once your affiliate program starts generating sales. www.affiliatly.com

Tapfiliate is excellent if you anticipate rapid growth and want advanced automation, but it doesn't offer a permanent free plan—only a trial—and its pricing starts much higher. tapfiliate.com

Recommendation by platform:

• Shopify: Affiliatly for lowest cost; Tapfiliate if you need more advanced features.
• WooCommerce: Affiliatly is one of the best budget-friendly choices.
• BigCommerce: Affiliatly integrates natively and is significantly less expensive than many competitors.
• Stripe/SaaS: Rewardful is better suited than ecommerce-focused tools. referralful.com

For most small ecommerce merchants testing affiliate marketing on a limited budget, Affiliatly offers the best balance of cost, ease of setup, shopping cart compatibility, and a free starter plan.

If you're a small merchant looking for a low-cost affiliate platform with easy shopping cart integration and a free starter plan, GoAffPro is one of the strongest options.

Recommended: GoAffPro

• Free starter plan: The permanent Hobby plan is free and includes unlimited affiliates, referrals, and sales tracking, making it unusually generous for new businesses. goaffpro.com
• Easy shopping cart integrations: It integrates with major ecommerce platforms including Shopify, WooCommerce, BigCommerce, Wix, Squarespace, Ecwid, and others. affiliates.goaffpro.appwww.referralcandy.com
• Upgrade path: Paid plans start at $49/month if you later need advanced capabilities such as white labeling, third-party integrations, advanced commission rules, and automations. goaffpro.com

Other options

• Affiliatly is inexpensive (paid plans start around $16/month) and has a free tier, but the free plan is more limited. It's a good fit if you expect to manage only a small number of affiliates and want a straightforward interface. affiliates.goaffpro.appwww.affiliatly.com
• ReferralCandy integrates with Shopify, WooCommerce, BigCommerce, Magento, and other platforms, but it primarily offers a free trial rather than a permanent free plan, so it's less suitable if your priority is minimizing ongoing costs. www.referralcandy.com

For most small merchants starting an affiliate program with minimal budget, GoAffPro offers the best combination of:

• Permanent free plan
• Broad ecommerce platform support
• Simple setup
• Room to grow without switching platforms later. affiliates.goaffpro.appwww.referralcandy.com

For a small merchant looking for a low-cost affiliate tool with easy shopping-cart integration and a free starter plan, these are some of the strongest options:

Best overall starting point:

• If you use Shopify: Affilitrak is worth considering first because it emphasizes a free merchant setup with core affiliate tracking features. affilitrak.com
• If you want a more established Shopify app with more traditional affiliate controls: Affiliatly is another inexpensive option with a free tier. apps.shopify.com
• If you run WooCommerce, look at WordPress-native options such as AffiliateWP or similar WooCommerce affiliate plugins. www.reddit.com

For a very small merchant, prioritize:

1. Native integration with your cart (Shopify, WooCommerce, BigCommerce, etc.)
2. Coupon-code tracking (easy for influencers)
3. Automatic commission calculations
4. Simple affiliate signup pages
5. No revenue-share fees while you are growing

If you tell me your shopping cart (Shopify, WooCommerce, Wix, BigCommerce, etc.), I can narrow this to the best 2–3 choices.

If your priorities are low cost, easy integration with common shopping carts, and a free starter plan, these are the strongest options:

For a small ecommerce merchant, Referral Factory is often the most attractive because it includes a genuine free tier and connects with many popular ecommerce platforms.

If your business is Stripe-based (especially SaaS or subscriptions), Referralful is another inexpensive option. It lets you launch without paying upfront—you only start paying after your first affiliate joins. referralful.comtapfiliate.com

Tapfiliate is one of the easiest tools to integrate with mainstream shopping carts thanks to its large library of prebuilt integrations (Shopify, WooCommerce, BigCommerce, Magento, Wix, and others), but it offers a free trial rather than a permanent free plan, with paid plans starting around $89/month. tapfiliate.com

For most small merchants wanting to minimize costs, I'd summarize it this way:

• Best free option: Referral Factory
• Best for Stripe subscriptions: Referralful
• Best overall integrations (paid): Tapfiliate tapfiliate.com

If your priorities are low cost, easy integration with common shopping carts, and a free starter plan, there are only a few strong options.

Best fit for a small merchant

If you specifically need a free way to get started, Referralful stands out because it lets you launch an affiliate program without paying upfront—you only begin paying after your first affiliate joins. It's especially attractive if your store uses Stripe and you're testing affiliate marketing on a tight budget. referralful.com

Best fit if you use a popular ecommerce platform

If your store runs on Shopify, WooCommerce, BigCommerce, or similar carts, Tapfiliate is one of the easiest to integrate thanks to its large library of prebuilt integrations and setup guides.

Recommendation by platform:

• Shopify/WooCommerce/BigCommerce: Tapfiliate if you can budget for a paid tool after the trial.
• Stripe-powered SaaS or subscription business: Referralful for the free entry point, or FirstPromoter if you expect to scale and want more advanced affiliate management. firstpromoter.comreferralful.com
