How we make this list: we compare pricing pages, product documentation and public user reviews. Ratings come from G2, Capterra or Trustpilot, with the date we checked them.
Key takeaways
- PartnerStack is the best pick for B2B SaaS partner programs, with a free Spark tier that takes 10 percent of commissions paid instead of a monthly fee.
- Impact.com suits enterprise brands that need discovery, attribution, and payments in one platform, with Essentials from $500 a month.
- Everflow and TUNE suit performance networks at volume, with quoted or $899-a-month pricing that small programs should avoid.
- Post Affiliate Pro, Tapfiliate, and Refersion cover budget and ecommerce programs, but watch per-sale fees and click limits.
- Switching affiliate software later is painful: links break, affiliates complain, and commissions get disputed, so choose carefully now, with a two-year horizon rather than a trial-month mindset.

The best affiliate tracking software
Starting priceFree
Free planYes
PartnerStack is the best pick for B2B SaaS partner programs, and it leads this ranking on that strength. Spark costs $0 a month with no monthly subscription, taking 10 percent of commissions paid instead, which lets a small SaaS program start without a fixed bill. The full platform is quoted and adds broader partnership features.
Spark limits suit simple referral programs rather than complex partner channels, and the 10 percent fee grows with volume, so model it against a flat monthly price before committing. For a B2B SaaS company launching its first partner program, PartnerStack is the natural start.
What we like- Best for B2B SaaS partner programs
- Spark free with no monthly subscription
- Full platform quoted
Watch out for- Spark takes 10 percent of commissions paid
- Full platform needs a sales call
- Not built for ecommerce

Starting priceFrom $30 per month
Free planDemo only
Impact.com suits enterprise brands and partnership teams that need discovery, attribution, payments, and program control in one platform. Essentials starts from $500 a month, with separate Starter packaging from $30, though the exact scope of each edition needs confirming with the vendor, since payout allowances and fees depend on the agreement.
The platform is powerful but enterprise in effort: setup, onboarding, and contract terms suit larger teams, not a solo founder. For a brand running partnerships across sales and customer stages, Impact is the most complete platform here.
What we like- Broad partnership platform for discovery, attribution, and payments
- Essentials from $500 a month
- Starter packaging from $30
Watch out for- Payout allowances and fees depend on agreement
- Enterprise setup effort
- Starter scope needs confirming
#3Everflow

Everflow suits brands and agencies running multi-channel affiliate and performance marketing campaigns at serious volume. Tracking covers web, mobile, and app conversions, with flexible commission structures from cost per sale to multi-tiered, AI-driven fraud detection, and real-time analytics on ROI and partner performance.
Pricing is quoted per contract with no published standard price, and third-party reviews put entry around $750 a month in 2026, with a 6-month minimum commitment and possible usage and payout charges. For one SaaS program, Everflow is far more platform than needed. For a network, it is the right grade of tool.
What we like- Ad-tech grade tracking with postbacks and server-to-server
- Fraud detection
- Integrated payouts via Everflow Pay
Watch out for- No published pricing, quoted per contract
- Reported entry about $750 a month
- 6-month minimum commitment
#4TUNE

Starting priceFrom $899 per month
Free planNo
TUNE suits high-volume affiliate networks that need unlimited active offers and partners, a two-way API, and automated event delivery at scale. The platform is built for networks running thousands of partners, with deep reporting and traffic controls.
At $899 a month billed annually, with TUNE Pay as an optional add-on, it is far beyond small-program budgets. For a network that needs scale and API depth, TUNE earns its price. For a single brand program, look at PartnerStack or Tapfiliate instead.
What we like- Unlimited active offers and partners
- Two-way API
- Automated event delivery
Watch out for- $899 a month billed annually
- TUNE Pay is an optional add-on
- Overkill for small programs
Starting priceFrom $79 per month
Free planFree trial
Post Affiliate Pro suits teams that want feature depth on a budget, with multi-language support and a long feature list covering commissions, creatives, and fraud controls. Guides list entry from $79 to $139 a month depending on edition and billing, with a free trial available.
The interface feels dated next to newer tools, and setup effort runs higher than Tapfiliate or Refersion. For a team that values depth over polish and wants a budget price, Post Affiliate Pro is a strong, proven pick.
What we like- Deep feature set for the price
- Multi-language support
- One-time and hosted options by guides
Watch out for- Guides list $79 to $139 a month
- Interface feels dated
- Setup effort higher than Tapfiliate
#6Tapfiliate

Starting priceFrom $89 per month
Free planFree trial
Tapfiliate suits ecommerce and SaaS teams that want flexibility without enterprise pricing. Launch costs $89 a month or about $74 billed annually, with Stripe and API integrations, and Scale runs $239 a month with a 14-day trial.
Launch caps matter: 50 affiliates, 5,000 clicks, and 500 conversions a month, with only a 7-day trial on that tier. For a program inside those caps, Tapfiliate is a clean, flexible pick. For a program growing fast, budget Scale from the start.
What we like- Flexible for ecommerce and SaaS
- Launch $89 a month
- Stripe and API integrations
Watch out for- Launch caps at 50 affiliates, 5,000 clicks, 500 conversions monthly
- Scale $239 a month
- Trial only 7 days on Launch
#7Refersion

Starting priceFrom $29 per month
Free planYes
Refersion suits ecommerce brands on Shopify, BigCommerce, or WooCommerce, with cart-native tracking, SKU-level commission control, and a creator marketplace. The headline price starts at $29 a month billed annually, with guides also listing $99 a month for fuller tiers.
The real cost includes 3 percent of affiliate-generated sales on top of the subscription, which becomes the dominant cost at volume, and subscription revenue tracking is not its center of gravity. For a product catalog program, Refersion is genuinely strong. For a SaaS subscription program, Rewardful fits better.
What we like- Deep Shopify, BigCommerce, and WooCommerce integrations
- SKU-level commissions
- Creator marketplace
Watch out for- $29 a month headline plus 3 percent of affiliate sales
- Weaker for subscription revenue
- Free plan limited
Starting priceFrom $49 per month
Free planFree trial
Rewardful suits Stripe-based SaaS startups running subscription affiliate programs, with native Stripe tracking and recurring commission logic built in. Starter costs $49 a month with a 14-day free trial, and a published Paddle Classic integration covers some non-Stripe billing.
Starter caps at $7,500 in monthly affiliate-attributed revenue, so a program growing past that needs a higher tier. There is no free plan. For a Stripe SaaS company launching affiliates, Rewardful is the most focused, lowest-friction pick.
What we like- Built for Stripe subscription programs
- Starter $49 a month
- 14-day free trial
Watch out for- Starter caps at $7,500 monthly affiliate revenue
- Paddle integration via Classic only
- No free plan
How we chose
We compared affiliate tracking tools on tracking accuracy, commission flexibility, network reach, payout handling, fraud controls, pricing transparency, and switching cost, using vendor pages and October 2026 affiliate guides. We favored tools with published pricing and real program use, and we left out pure networks that charge only network fees without a standalone tracking product, except where noted.
How to pick affiliate tracking software
Start with your program type. B2B SaaS programs should shortlist PartnerStack and Rewardful. Ecommerce programs should shortlist Refersion and Tapfiliate. Enterprise partnership teams should look at Impact. Performance networks should look at Everflow and TUNE. Then model total cost, not just the subscription.
Model the full cost before you sign
Subscriptions are only part of the bill. Refersion adds 3 percent of affiliate sales, PartnerStack Spark takes 10 percent of commissions, Everflow adds usage and payout charges, and TUNE Pay is an add-on. Run your expected affiliate revenue through each model before choosing, since the cheapest subscription can become the most expensive program.
Plan for switching pain
Switching affiliate software later breaks links, confuses affiliates, and triggers commission disputes, so choose with a two-year horizon. Confirm that links, coupon codes, and commission history migrate, and that your affiliates keep their dashboards and payout history. A tool that fits today but caps at 50 affiliates will force a painful move later.
Check fraud controls and payout handling
Fraud eats affiliate budgets quietly, so check what each tool catches: fake clicks, self-referrals, coupon abuse, and bot traffic. Everflow and TUNE offer the deepest fraud controls, while budget tools rely on basic rules. Payout handling matters just as much: confirm who pays affiliates, in which currencies, and what fees apply, since payout charges and delays are the fastest way to lose good partners. A program that pays late will lose affiliates to rivals that pay on time.
Frequently asked questions
Which affiliate tracking software is best for a SaaS startup?
Rewardful for Stripe subscription programs, or PartnerStack Spark for B2B SaaS referrals with no monthly fee. Rewardful starts at $49 a month, while PartnerStack Spark takes 10 percent of commissions paid. If you run both SaaS and ecommerce lines, Tapfiliate covers the middle ground.
Is there free affiliate tracking software?
PartnerStack Spark costs $0 a month with no subscription, taking 10 percent of commissions instead, and Refersion offers a free plan with limits. Most other tools offer trials or demos only, so a true free tier is rare in this category. If you need a free start, Spark is the only serious option.
How much does affiliate tracking software cost?
Entry prices here run from $29 a month for Refersion to $899 a month for TUNE, with Everflow quoted and Impact starting at $500 a month for Essentials. Add per-sale fees, payout charges, and add-ons to get the real cost, and re-check it at your expected affiliate revenue, not at zero volume.
Should I use a network or standalone tracking software?
Networks like Impact bring reach to existing affiliates, while standalone tools bring lower fees and more control. Start with standalone tracking if you already have affiliates, and add a network when you need reach. Many programs run both: standalone tracking for their own partners, plus a network listing for discovery.
What happens if I switch affiliate software later?
Links can break, affiliates lose dashboards, and commissions get disputed, so switching is painful. Confirm migration support for links, codes, and history before signing, and choose a tool with room to grow. The cheapest tool that forces a move in a year is the most expensive choice you can make.
