How this ranking works
One method for every tool. We compared documented features and published prices; we did not run hands-on tests. Value carries the most weight.
Full methodThis list is for SaaS founders and growth leads setting up their first affiliate or referral program who need to know how the bill will grow as affiliates bring in revenue. Most SaaS affiliate tools now price by tiers of affiliate-attributed revenue, a few charge a flat fee with no revenue cap, and the larger partner platforms quote after a demo. We compared documented features and published prices on each vendor's own pages, and scored value at 40%, features at 35% and ease of use at 25%. Value here means what the entry plan includes, how quickly the price climbs with affiliate revenue, and what extra fees sit on payouts. The starting price is the cheapest paid plan in USD that a SaaS company can buy. Where a vendor did not publish a USD price we could confirm, the price is marked as pending.
The verdict
FirstPromoter gives a new SaaS program the most at the entry price: $49 per month covers up to $5,000 a month in affiliate revenue, 1,000 affiliates, 3 campaigns, unlimited team members and multi-tier commissions. Rewardful costs the same $49, allows $7,500 a month in affiliate revenue and takes 0% of that revenue, which makes it the easiest Stripe setup to recommend. Partnero is the pick if you want a flat fee: $49 per month billed annually with unlimited partners, transactions and revenue. Tolt starts higher at $99 but includes automatic payouts and covers up to $20k a month. Cello is built for in-app user referrals and has a free partner plan. Reditus adds a marketplace of B2B SaaS affiliates, Tapfiliate and Post Affiliate Pro meter clicks and tracking requests, and PartnerStack and impact.com are sales-led platforms for larger partner programs.

Best forSaaS founders who want the most features and unlimited team seats at a $49 entry price.
FirstPromoter ranks first because its $49 Starter plan includes more than any other entry plan here. The pricing page lists Starter at $49 per month or $490 per year for up to $5,000 a month in revenue from affiliates, with up to 1,000 affiliates, 3 campaigns and unlimited team members. Starter already has coupon codes synced in Stripe, sub-ID tracking, cookie life of up to 9999 days, recurring and lifetime commissions, double-sided rewards and multi-tier commissions across up to 3 levels. Billing connects to Stripe, Paddle, Chargebee, Recurly and Braintree, and mass payouts go out by PayPal, Wise, Stripe, crypto or bank transfer in 190 currencies. The trade-off is the revenue cap: past $5,000 a month you move to Business at $99, which covers up to $15,000. A custom dashboard domain, a custom email domain and VAT-compliant self-billed invoices for EU companies also start on Business.

- ✓14-day free trial with no credit card required
- ✕Starter is capped at $5,000 a month in affiliate revenue, lower than Rewardful's $7,500

- ✕Custom dashboard domain and custom email domain need Business at $99 per month
- Pricing model:

- Affiliates on entry plan:
- Up to 1,000
- Team members:

Bottom line: FirstPromoter is the strongest all-round start for a SaaS affiliate program, with seats, campaigns and multi-tier commissions included at $49. Plan for Business at $99 once affiliates pass $5,000 a month.

Best forFounders who want a flat monthly fee that does not rise with affiliate revenue.
Partnero is the clearest answer for founders who do not want their software bill to grow with affiliate revenue. Its pricing page lists Starter at $49 per month billed annually or $59 billed monthly, and says all plans include unlimited partners, transactions and revenue with no overage fees. A program that grows from $2,000 to $40,000 a month in affiliate revenue pays the same Starter fee, where revenue-tier tools would move it up several tiers. Starter includes a ready-made partner portal and signup pages, email templates, link, coupon and referral tracking, automated PayPal and Wise payouts and plug-and-play integrations such as Stripe and Shopify. Affiliate, referral, influencer and newsletter programs all work on Starter. The limits are on seats and programs: Starter has 1 program and 1 team member, extra seats cost $29 per user per month, and advanced commission structures, messaging and approval workflows come with Partner at $159 per month billed annually.
- ✓Flat fee with no revenue cap or overage fees
- ✓Longest free trial on this list at 30 days, with all features
- ✓Every program type is available on Starter
- ✕Starter includes 1 program and 1 team member
- ✕Extra seats cost $29 per user per month
- ✕Advanced commission structures need the Partner plan at $159 per month billed annually
- Pricing model:
- Flat fee, unlimited revenue
- Entry plan cap:
- No revenue cap
- Team members on Starter:
- 1, extra seats $29 per user per month
- Programs on Starter:

- Free trial:

Bottom line: Partnero is the best value once affiliate revenue is large or unpredictable, because the fee stays flat. Small teams should price in extra seats before choosing it.

Price

Best forStripe-billed startups that want the fastest setup and a 0% transaction fee.
Rewardful is the simplest way to put an affiliate program on top of Stripe billing. Its pricing page says it starts at $49 per month, that every plan includes a 14-day free trial and unlimited affiliates, and that it takes a 0% transaction fee on affiliate-attributed revenue. Starter covers up to $7,500 a month in that revenue, Growth at $99 covers up to $15,000 and Enterprise starts at $149 with tiered pricing above that. Annual billing gives 12 months for the price of 10. Every plan includes all integrations, REST API access, multiple currencies, first or last-touch attribution, coupon tracking, double-sided incentives and self-referral fraud detection. The two-way Stripe sync shows affiliate data inside the Stripe dashboard and adjusts commissions when a referred customer upgrades, downgrades or cancels. Starter is limited, though: 1 campaign, up to 2 team members, and no branded portal, custom domain or private campaigns, which arrive on Growth.
- ✓0% transaction fee on affiliate-attributed revenue on every plan
- ✓Highest entry revenue cap among the $49 plans at $7,500 a month
- ✓Unlimited affiliates and visitors on every plan
- ✕Starter allows 1 campaign and up to 2 team members
- ✕A branded affiliate portal and custom domain need Growth at $99 per month
- ✕Optional Managed Payouts carry a 3% processing fee
- Pricing model:
- Tiers by monthly affiliate-attributed revenue
- Entry plan cap:
- Up to $7,500 a month in affiliate-attributed revenue
- Transaction fee:
- 0%
- Team members on Starter:
- Up to 2
- Free trial:
- 14 days on every plan
Bottom line: Rewardful is the easiest pick for a Stripe-billed SaaS that wants to launch in an afternoon and keep 100% of affiliate revenue. Budget for Growth if you want a branded portal.

Best forSaaS teams that want affiliate payouts, invoices and tax forms handled for them.
Tolt costs more at the start than Rewardful or FirstPromoter, but its entry plan stretches further and takes payouts off your plate. The pricing page lists Growth at $99 per month billed monthly for up to $20k a month in partner revenue, with unlimited affiliates and referrals, a branded portal on your own domain, 5 programs, 5 team members and custom commissions with double-sided rewards. Every plan pays affiliates for you by PayPal, Wise, bank or wire, generates affiliate invoices and collects W-9 and W-8 forms before a first payout, with 1099 filing. That service costs 2% of what is paid out. Billing syncs both ways with Stripe, Paddle and Chargebee, and an in-app referral widget lets users share from inside your product. Pro at $199 per month covers up to $50k and adds Radar fraud protection, unlimited programs and seats, and removes the Powered by Tolt link. Annual billing gives 2 months free.
- ✓Entry plan covers up to $20k a month in partner revenue
- ✓Payouts, affiliate invoices and US tax forms included on Growth
- ✓Imports affiliates, links and commission history from other platforms
- ✕Highest self-serve entry price among the revenue-tier tools at $99
- ✕Payouts cost 2% of what is paid out
- ✕Radar fraud protection needs Pro at $199 per month
- Pricing model:
- Tiers by monthly partner revenue
- Entry plan cap:
- Up to $20k a month in partner revenue
- Transaction fee:
- 2% of payouts
- Team members on Growth:
- 5
- Free trial:
- 14 days, no credit card
Bottom line: Tolt is the pick when tax forms and payouts are the part of affiliate management you most want to hand off. Compare the 2% payout fee with doing payouts yourself.

Best forProduct-led SaaS teams that want users to refer from inside the app.
Cello is different from the rest of this list because it starts with your own users rather than outside affiliates. Its pricing page splits plans into user referrals and partner referrals. User referral plans start at $65 per month, shown at 32% off, for up to $10K in referral ARR with unlimited referrals, 1 campaign, all integrations and features, and 0% transaction costs; Grow at $200 covers up to $50K. Partner referrals have a free plan with 1 campaign, 5 transacting partners and 5% transaction costs, and Plus at $80 per month raises that to 25 partners at 3.5%. The product is an SDK for web and mobile that gives every user a personal referral link without a separate sign-up, with a custom launcher in your menu, a floating button and contextual prompts at moments of success. Conversions come in through Stripe or Chargebee webhooks, HubSpot forms or Salesforce. The trade-off is setup: it needs developer time to embed the SDK.
- ✓Free partner plan with 5 transacting partners and unlimited referral ARR
- ✓0% transaction costs on user referral plans
- ✓Referral UI lives inside your product on web and mobile
- ✕Partner plans charge 5% transaction costs on Free and 3.5% on Plus and Pro
- ✕The Start plan allows 1 campaign
- ✕Needs an SDK install, which is more work than a tracking script
- Pricing model:
- User referrals by referral ARR; partner plans with transaction costs
- Entry plan cap:
- Up to $10K referral ARR on Start
- Transaction fee:
- 0% on user referrals; 5% on free partner plan
- Free plan:
- Partner referrals, 1 campaign, 5 transacting partners
- Mobile SDK:
- iOS, Android, Flutter, React Native
Bottom line: Cello is the best choice when your customers, not bloggers, are the likely referrers. The free partner plan is a low-risk way to test outside affiliates too.

Best forB2B SaaS teams that need help finding affiliates, not just tracking them.
Reditus is built for B2B SaaS companies whose real problem is finding affiliates who reach their buyers. The pricing page says teams can recruit from a network of 28,000+ B2B SaaS affiliates and run an in-app referral program in the same platform. The Growth plan includes the in-app referral program, the full affiliate toolkit, automated payouts, unlimited advocates and affiliates, the Affiliate Finder, multiple affiliate tiers, campaigns, fraud detection with auto-reject, API and webhook access and UID tracking that works without emails. Growth covers up to 60K ARR, and Scale Up raises that to 360K ARR on an annual-only plan that adds a marketplace listing, a vetted affiliate database and a dedicated account manager. Reditus also offers free migration that keeps existing affiliate links working. The page lists plan prices without a currency symbol from our location, so we mark the price as pending rather than assume dollars. Done-for-you program management is sold separately.
- ✓Affiliate discovery built in, aimed only at B2B SaaS
- ✓Unlimited advocates and affiliates on every plan
- ✓Free white-glove migration on every plan
- ✕Pricing page does not show a currency, so we could not confirm a USD price
- ✕Growth covers up to 60K ARR before an upgrade

- Pricing model:
- Tiers by referral ARR

- 28,000+ B2B SaaS affiliates

Best forTeams that sell on both Stripe and a store platform and want one tracker.
Tapfiliate prices by plan and usage rather than affiliate revenue, which can work for a SaaS with high-value deals and modest traffic. Its pricing page lists Launch at $89 per month, or $74 per month on annual billing, with 1 program, 50 affiliates, 1 team member, 5,000 clicks and 500 conversions a month. Above those limits, Launch charges $1.5 per 1,000 extra clicks and $15 per 1,000 extra conversions. Launch includes 30+ integrations such as Stripe and Shopify, real-time reporting, recurring commissions, coupon tracking and affiliate payment methods. Scale at $179, or $149 annually, raises limits to 150 affiliates, unlimited programs, 100,000 clicks and 10,000 conversions, and adds multi-level commissions, automated payouts through Trolley, deeplinks and short links. Full white label sits on Enterprise. The 50-affiliate cap on Launch is the limit a growing SaaS program is likely to hit first.
- ✓Covers SaaS and ecommerce with the same tracking
- ✓No revenue cap; limits are on clicks and conversions
- ✓14-day free trial on every plan
- ✕Launch caps you at 50 affiliates, 1 program and 1 team member
- ✕Overage fees of $1.5 per 1,000 clicks and $15 per 1,000 conversions on Launch
- ✕Automated payouts and MLM need Scale at $149 per month billed annually
- Pricing model:

- 5,000 clicks and 500 conversions a month
- Affiliates on entry plan:
- 50
- Team members on Launch:
- 1
- Free trial:

Bottom line: Tapfiliate fits SaaS companies that also sell through a store and want one tracker for both. Its 50-affiliate entry cap makes it a poor fit for open, high-volume programs.

Best forTeams that need complex commission rules or plan to run their own affiliate network.
Post Affiliate Pro has the deepest commission and network options on this list, at the cost of a steeper setup. Its pricing page lists Starter at $89 per month or $79 per month billed annually, with 10,000 tracking requests a month, unlimited affiliates, more than 125 plugins, advanced reporting, fraud protection and up to 2 hours of setup and integration help. Tracking requests count impressions, events, clicks and sales, so a SaaS with heavy link traffic will outgrow Starter quickly; Pro at $129 annually raises the limit to 1M and adds more than 220 integrations. Ultimate adds performance rewards, multiple administrators, a lifetime referrals manager and forced matrix commissions, and Network supports multiple merchant accounts for running your own affiliate network. Some features are add-ons, such as multiple currencies at $19 per month and the lifetime referrals manager at $9 per month on lower plans. The product predates the Stripe-first SaaS tools and feels more like general affiliate software.
- ✓Unlimited affiliates and no revenue-based tiers
- ✓Setup and integration help included, up to 2 hours on Starter
- ✓30-day free trial
- ✕Starter allows only 10,000 tracking requests a month
- ✕Several features are paid add-ons, such as multiple currencies at $19 per month
- ✕Interface and setup are more involved than the SaaS-first tools here
- Pricing model:
- Flat plans with tracking request limits
- Entry plan cap:
- 10,000 tracking requests a month
- Affiliates:
- Unlimited
- Multiple currencies:
- Add-on, $19 per month
- Free trial:

Bottom line: Post Affiliate Pro is worth it for programs with unusual commission rules or network ambitions. A typical SaaS starting out will get going faster with a Stripe-first tool.

Best forVenture-backed B2B SaaS companies running several partner types at once.
PartnerStack is a partner relationship platform rather than a self-serve affiliate tracker, and its pricing reflects that. The pricing page lists Launch, Growth and Enterprise plans but no prices, and its FAQ says pricing is based on program size, feature needs and level of support and is confirmed during a demo. Launch includes either affiliate link tracking or lead and deal registration, access to the PartnerStack Marketplace, partner payments built for B2B SaaS sales cycles, onboarding and enablement tools, CRM integrations and an AI assistant with an MCP connector. Growth adds advanced integrations, a learning management system for partner training, partner challenges, MDF management and advanced segmentation. Enterprise unlocks link tracking, lead and deal registration together, plus custom workflows and a designated CSM. The FAQ says there is no limit on partners and that most teams are running in weeks. For a founder testing affiliates for the first time, that is a lot of platform.
- ✓Marketplace for getting discovered by B2B partners
- ✓Covers affiliates, referral partners and co-selling in one platform
- ✓No limit on the number of partners
- ✕No published prices; plans are confirmed during a demo
- ✕Launch includes affiliate link tracking or deal registration, not both
- ✕Implementation takes weeks for most teams, by PartnerStack's own FAQ
- Pricing model:
- Quoted after a demo
- Entry plan cap:
- Not published
- Partners:
- No limit
- Setup:
- Guided onboarding on all plans
- Free trial:

Bottom line: PartnerStack belongs on the shortlist once partners are a planned revenue channel with a dedicated owner. It is overkill for a first affiliate test.

Best forLarger companies that want access to a big partner marketplace and advanced attribution.
impact.com is the heaviest platform here and is priced for companies already spending real money on partners. Its pricing page says all plan prices are in USD and starts self-serve at $30 per month plus 2.5% of revenue, but that Starter tier is available only for ecommerce platforms such as Shopify, WooCommerce and BigCommerce, so it does not apply to a typical SaaS billed through Stripe. The realistic SaaS entry point is Essentials at $500 per month, which includes up to $2,500 a month in partner payouts and requires a minimum of $2,500 a month in processed payouts. Essentials includes all tracking and reporting, the partner marketplace, multi-domain programs, dedicated support, and creator and customer referral modules. Pro at $2,500 per month adds API-based tracking, custom commission rates and Data Lab analytics. The platform lists discovery across 250K+ partners, payouts in 70+ currencies and cookieless cross-device attribution.
- ✓Largest partner marketplace on this list
- ✓Affiliate, creator and customer referral programs in one platform
- ✓Published USD tiers, which is rare for enterprise partner platforms
- ✕The $30 Starter tier is only for platforms such as Shopify and WooCommerce, so SaaS teams start at $500
- ✕Essentials requires a minimum of $2,500 a month in processed partner payouts
- ✕API-based tracking needs Pro at $2,500 per month
- Pricing model:
- Monthly fee with included partner payouts
- Entry plan cap:
- Up to $2,500 a month in partner payouts on Essentials
- Transaction fee:
- 2.5% of revenue on Starter
- Partner network:
- 250K+ partners
- Payout currencies:
- 70+
Bottom line: impact.com makes sense for a SaaS that already pays partners thousands a month and wants a large marketplace. Early programs will pay far less with the self-serve tools above.
What to check before you pay
Decide between revenue tiers and a flat fee
Rewardful, FirstPromoter, Tolt, Cello's user referral plans and Reditus price by how much revenue your affiliates bring in. Rewardful Starter covers up to $7,500 a month, FirstPromoter Starter up to $5,000, Tolt Growth up to $20k and Reditus Growth up to $60K ARR, and each moves you up a tier when you pass the cap. Partnero charges a flat fee with unlimited revenue, and Tapfiliate and Post Affiliate Pro meter clicks, conversions or tracking requests instead.
Look for fees on top of the subscription
Rewardful takes 0% of affiliate-attributed revenue, and its optional Managed Payouts carry a 3% processing fee. Tolt charges 2% of what it pays out to affiliates. Cello's partner plans charge 5% transaction costs on the free plan and 3.5% on Plus and Pro. impact.com Starter adds 2.5% of revenue to its $30 monthly fee and is only available for ecommerce platforms such as Shopify and WooCommerce.
Check the billing integration first
SaaS revenue usually runs through Stripe, Paddle or Chargebee, and the tool needs to see renewals, upgrades and refunds to pay recurring commissions correctly. FirstPromoter lists Stripe, Paddle, Chargebee, Recurly and Braintree. Tolt syncs both ways with Stripe, Paddle and Chargebee. Rewardful calls itself a Premier Stripe Partner and shows its data inside the Stripe dashboard.
Count seats, campaigns and affiliates
Entry plans differ more on limits than on tracking. FirstPromoter includes unlimited team members on every plan and caps Starter at 1,000 affiliates and 3 campaigns. Rewardful Starter allows up to 2 team members and 1 campaign. Partnero Starter includes 1 program and 1 team member, with extra seats at $29 per user per month. Tapfiliate Launch allows 1 program, 50 affiliates and 1 team member.
FAQ
What is the best affiliate software for SaaS in 2026?
FirstPromoter ranks first for a new SaaS program: $49 per month covers up to $5,000 a month in affiliate revenue with unlimited team members and multi-tier commissions. Rewardful is second at the same $49 with a $7,500 monthly cap and a 0% transaction fee.
Is flat pricing or revenue-based pricing cheaper for affiliate software?
Revenue-based tiers are cheaper while affiliates bring in little: Rewardful and FirstPromoter both start at $49 per month. Once affiliate revenue grows, a flat fee wins, because Partnero charges $49 per month billed annually with unlimited revenue while Rewardful moves to $99 above $7,500 a month.
Is there free affiliate software for SaaS?
Cello's partner referrals plan is free with 1 campaign and 5 transacting partners, and charges 5% transaction costs. The other tools on this list offer free trials instead: 14 days for Rewardful, FirstPromoter, Tolt, Tapfiliate and Reditus, and 30 days for Partnero and Post Affiliate Pro.
Do affiliate platforms take a cut of revenue or payouts?
Some do. Rewardful takes 0% of affiliate-attributed revenue but charges 3% on its optional Managed Payouts, Tolt charges 2% of what it pays out, and Cello's partner plans charge 3.5% to 5%. impact.com's Starter tier adds 2.5% of revenue.
Which affiliate tool works best with Stripe?
Rewardful calls itself a Premier Stripe Partner and shows affiliate data inside the Stripe dashboard. FirstPromoter, Tolt, Partnero and Tapfiliate also integrate with Stripe, and FirstPromoter and Tolt add Paddle and Chargebee.
