Best Affiliate Marketing Software in 2026

impact.com is a partnership-management platform that handles affiliate programmes alongside influencer and creator partnerships, customer referral programmes and retail media. It was co-founded by a team that includes Roger Kjensrud, its co-founder and chief technology officer, and says technology partners that integrate with it can reach more than a million active partnerships. It also serves agencies, offering white-label reporting and partner operations across client programmes.

impact.com publishes four plans in US dollars. Starter, for brands starting their partnerships channel or spending up to US$300,000 a year on marketing, costs US$30 a month plus 2.5% of revenue and is available only for stores on Shopify, WooCommerce, BigCommerce, Adobe Commerce and Square. Essentials, for brands with up to US$2m a year in e-commerce revenue, costs US$500 a month and includes up to US$2,500 a month in partner payouts. Pro, for brands with US$2m to US$15m in e-commerce revenue, costs US$2,500 a month and includes up to US$14,300 a month in partner payouts. Enterprise, for brands above US$15m or with multi-channel operations, is custom-priced. Add-ons include Creator Premium, Advocate Premium, Optimize, AI Search Visibility and Brand Safety tools.

Its strength is scope: one contract can cover affiliates, influencers and referral programmes with shared tracking and payments. Its limitations are complexity for small teams, a revenue-share fee on Starter, and payout minimums built into the higher plans.

PartnerStack is a partner-management platform for B2B companies, particularly software vendors, that run affiliate, referral, reseller and other performance-based partner programmes. It describes itself as an AppDirect company, and its pricing page shows customers such as Apollo, monday.com, PandaDoc, Aircall, CallRail and Gorgias.

PartnerStack sells three plans with no published prices; pricing depends on programme size, features and support and is confirmed in a demonstration. Launch includes either affiliate link tracking or lead and deal registration, access to the PartnerStack Marketplace for partner discovery, the PartnerStack AI and MCP Connector, partner payments, onboarding, training and enablement tools and CRM integrations. Growth adds advanced CRM and marketing-automation integration support, a learning management system for partners, partner challenges and incentives, MDF management and payments and advanced partner segmentation. Enterprise adds full link tracking together with lead and deal registration, custom workflows and integrations, a designated customer-success manager with executive sponsorship and semi-annual business reviews, partner introductions and recruitment support, and priority support. All plans include guided onboarding, with no caps on partners or internal users; implementation typically takes weeks.

Its strength is its focus on B2B partnerships, including resellers and MDF, which most affiliate tools lack. Its limitations are the absence of public prices and the fact that the Launch plan offers only one tracking model.

TUNE is a partner-marketing platform for advertisers and affiliate networks. It launched its first product, HasOffers, in 2009 as a white-label solution that allowed anyone to manage an affiliate network, and describes itself as one of the first cloud-based SaaS platforms for affiliate marketing. In 2018 its Attribution Analytics product was acquired by Branch; in 2019 it retired the HasOffers name; and in 2020 TUNE was acquired by Constellation Software.

TUNE publishes pricing for advertisers. The Scale plan costs US$1,500 a month paid annually and includes 2,500 conversions a month, marketplace access (with additional network and processing fees), a customer-success manager, email, chat and phone support, and fee-based partner payments and onboarding. Custom contracts support more than 2,500 conversions a month and add developer-team support. Features include a secure custom application and tracking domain, campaign management, promo codes, advanced targeting, mobile, mobile-web and desktop tracking, advanced commissioning, a partner API, real-time reporting, partner invoicing, proactive fraud prevention, funnel metrics, a two-way API, performance automation and programme migration. TUNE lists SOC 2 Type II and SOC 1 Type II accreditation and GDPR compliance.

TUNE's strengths are its tracking depth and maturity with networks. Its limitations are a high entry price, a conversion cap on Scale and extra fees for payments and marketplace use.

Everflow is a partner-marketing platform used by brands, networks, agencies and publishers, which it asks about separately when quoting. It describes itself as a bootstrapped company and states that it holds SOC 2 certification and runs on Google Cloud infrastructure.

Everflow does not publish prices: its pricing page asks for monthly affiliate payout levels, from none up to more than US$1m, and returns a personalised quote. It requires a six-month commitment on its plans. Every plan includes a one-time onboarding service with its customer-success team covering setup, team training and first-conversion tracking, free data migrations from other networks and platforms (including API-based migrations from TUNE, CAKE and HitPath), and ongoing support through live chat, email, tickets and scheduled calls. Its platform modules are described as tracking everything, directly managing partners, attributing user activity, discovering relevant partners, optimising traffic sources and getting more from advertising. Everflow also runs an agency partner programme and pays referral fees of up to US$4,000 for leads.

The free migration from TUNE, CAKE and HitPath shows Everflow's main market: performance marketers moving off older tracking systems. Its limitations are the lack of public pricing and the six-month minimum commitment, which make it less suited to companies testing an affiliate channel for the first time.

Refersion is an affiliate-marketing platform for e-commerce brands. It says more than 60,000 brands have registered, that it has managed 6.6 million affiliates, processed more than 614,000 orders daily, tracked US$2bn in affiliate revenue and handled US$366m in affiliate commissions; these are company figures. Refersion has been acquired by Pantastic, according to a press item on its own site, and has launched unified payments for affiliate payouts.

Refersion publishes four tiers. A free listing places a brand in the Refersion Marketplace, where it can publish a percentage-of-sale offer that affiliates can view and apply to. Launch, for new brands, costs US$39 a month (US$29 on annual billing) plus 3% of affiliate-driven sales and includes one-click payouts via PayPal and percentage-of-sale or subscription commissions. Growth, for brands nearing US$1m in gross merchandise value, costs US$199 a month (US$159 annually) plus 2% of affiliate-driven sales and adds advanced commissions, new-versus-returning-customer commissions and multi-store management. Scale, for brands above US$1m GMV a year, adds premium support, white-glove onboarding, a Slack channel and early feature access.

Refersion's strengths are its marketplace and e-commerce focus. Its limitations are the percentage fee on affiliate sales, which grows with programme success, and the fact that advanced commission rules require the Growth plan.

Tapfiliate is self-service affiliate tracking software for SaaS, e-commerce and subscription businesses. It runs its own marketplace of active affiliates and offers its interface in English, German, Spanish, French and Portuguese.

Two plans are published. Launch costs US$89 a month, or US$74 a month billed annually, and covers up to 50 affiliates, 5,000 clicks and 500 conversions a month and one team member; overages cost US$1.50 per 1,000 clicks and US$15 per 1,000 conversions. Scale, the most popular plan, costs US$179 a month, or US$149 billed annually, with unlimited affiliates and programmes, 100,000 clicks and 10,000 conversions a month, five team members, advanced affiliate and commission management, and overages of US$1 per 1,000 clicks and US$10 per 1,000 conversions. An enterprise tier is tailored. Both self-service plans have a 14-day free trial. In November 2026 Tapfiliate ran a promotion offering two years for the price of one to new customers.

Tapfiliate's strengths are clear published limits and overage rates. Its limitations are the low affiliate and conversion caps on Launch, overage charges that can make costs unpredictable for fast-growing programmes, and the need for the Scale plan for multiple programmes.

Post Affiliate Pro is affiliate software that says it has supported thousands of companies since 2005. Alongside software for a single company's affiliate programme, it sells affiliate network software for running a network, and offers plugins and integrations to extend the product.

The pricing page lists three self-service plans, each with a free trial. Starter, for small businesses beginning affiliate marketing, costs US$89 a month and includes 10,000 tracking requests a month, unlimited affiliates, more than 125 plugins, advanced reporting, fraud protection, a customisable interface and themes, full setup and integration of up to two hours, an AI assistant and lifetime support. Pro, for a simple affiliate programme, costs US$139 a month and raises the limit to one million tracking requests a month with more than 220 integrations. Ultimate, its most popular plan, costs US$269 a month for six million tracking requests and adds performance rewards, multiple administrators, a lifetime referrals manager, site replication and forced-matrix multi-level structures. Custom configurations are available on request.

Post Affiliate Pro's breadth and its support for multi-level and network models are its strengths. Its limitations are a very low tracking-request cap on Starter, setup assistance capped at two hours on that plan, and the fact that multi-administrator access requires Ultimate.

Rewardful is affiliate and referral software for SaaS and subscription businesses, built around integration with Stripe and more than 20 other tools. It is a small company: its about page says it has eight years of growth and 13 employees in nine countries.

Every plan includes a 14-day free trial, unlimited affiliates and a 0% transaction fee on affiliate-attributed revenue. Pricing is tiered by how much revenue affiliates generate: Starter costs US$49 a month for up to US$7,500 a month in affiliate-attributed revenue; Growth, the most popular plan, costs US$99 a month for up to US$15,000; and Enterprise starts at US$149 a month for up to US$30,000 a month on its entry tier, with higher usage moving to higher tiers. Annual billing gives two months free (Starter US$490 a year, Enterprise from US$1,490). Prices are in US dollars, excluding tax.

Rewardful's advantages for SaaS are recurring-commission handling, direct Stripe integration and the absence of a revenue share, so a successful programme does not raise fees except at tier thresholds. Its limitations are its focus on Stripe-centric subscription businesses, a small team, and revenue-based tiers that push growing programmes into higher plans.

FirstPromoter is affiliate and referral management software for SaaS companies, which it says are used by more than 3,000 SaaS businesses. It competes directly with Rewardful on pricing tied to affiliate revenue.

FirstPromoter publishes monthly and yearly plans. Starter costs US$49 a month, or US$490 a year, for programmes generating up to US$5,000 a month in revenue from affiliates. Business, its most popular plan, costs US$99 a month for up to US$15,000 a month in affiliate revenue. Enterprise costs US$149 a month, or US$1,490 a year, for programmes above US$15,000 a month. A 14-day free trial requires no credit card. Server-to-server notifications for media buyers are available only on the highest tier. The company cites customers such as CustomGPT, which it says has generated more than US$1m in revenue from affiliates since joining in 2023, a company-reported case study.

FirstPromoter is a strong fit for SaaS companies that want straightforward recurring-commission tracking without a revenue share. Its limitations are that its lowest revenue threshold is below Rewardful's, that server-side tracking is reserved for the top plan, and that it is designed for subscription software rather than e-commerce.

LeadDyno is affiliate-management software that markets itself to health and wellness, SaaS and fashion and lifestyle businesses. Its plans include unlimited clicks and conversions, automated link tracking, commissions and partner communications, and it offers a 30-day free trial, longer than most competitors here.

LeadDyno prices its plans by the number of active affiliates and programme complexity. Lite costs US$49 a month and includes 50 active affiliates, one reward structure, one commission plan, one affiliate group, an affiliate dashboard, 18 months of reporting and fraud prevention. Essential costs US$129 a month for 150 active affiliates, three commission plans and two affiliate groups. Advanced, for growing an established programme, costs US$349 a month and adds features such as multi-level marketing, a customisable affiliate sign-up form, a custom affiliate dashboard domain and the ability to restrict affiliate codes to specific products for Stripe and Shopify. Higher tiers add historical data export, unlimited team members, customer-lifecycle commissions, custom setup of up to 16 hours, priority support and personalised reporting. Annual billing saves 15%.

LeadDyno's unlimited clicks and conversions make costs predictable. Its limitations are the low active-affiliate caps on lower plans and the jump in price from Essential to Advanced for features such as MLM and product-restricted codes.

UpPromote is an affiliate and influencer marketing app built primarily for Shopify stores, including Shopify Plus merchants, and offers a free influencer search tool alongside its affiliate features. Its pricing combines a monthly subscription with a performance fee on successful referral sales that declines as plans get more expensive.

The Free plan costs nothing and includes one affiliate programme, review of up to US$3,000 of referral sales a month and one coupon per affiliate. Growth costs US$29.99 a month (US$299.90 a year) plus 2% of successful referral sales and adds unlimited programmes. Professional costs US$89.99 a month (US$899.90 a year) plus 1.5% of successful referral sales and adds unlimited coupons per affiliate and anti-leak discount protection. Enterprise carries a 1% performance fee and adds unlimited staff accounts and multi-store sync. The performance fee applies only to sales from approved referrals tracked in the app. Other features include a referral marketplace listing and store-credit payment of commissions.

UpPromote's free plan makes it easy for a small store to start a programme. Its limitations are the percentage fee on referral sales in paid plans, its dependence on Shopify, and coupon and staff limits on lower tiers.

GoAffPro is affiliate-marketing software for online stores that offers a free plan with unlimited affiliates, sales and revenue. It integrates with Shopify, BigCommerce, WooCommerce, PrestaShop, Wix, Webflow, Ecwid, Squarespace, Magento, Weebly, Square and Shoplazza, which makes it one of the more platform-agnostic store tools in this list.

The Hobby plan is free and is recommended for merchants with fewer than 100 daily orders, with a basic affiliate portal. Premium costs US$49 a month and is recommended for stores with more than 100 daily orders; it fully unlocks the admin panel and adds a branded affiliate portal, targets and bonuses, multiple groups and sign-up pages, multi-level marketing, a membership-fees plugin, a tax plugin, a payout scheduler, server-to-server callbacks and third-party integrations. Business starts at US$99 a month and adds automations, custom compensation plans, MLM level compression, vanity subdomain links and fraud-management tools. Enterprise adds a dedicated account manager, custom mobile apps for affiliates and custom features. GoAffPro publishes API documentation and a GitHub presence for developers.

GoAffPro's free tier and absence of a revenue share make it the cheapest option here for small stores. Its limitations are the basic portal on the free plan, the need for Business to access fraud tools, and less brand recognition among affiliates than marketplace-based platforms.
