Running an affiliate program is one of the most reliable ways for a SaaS company to grow. You only pay when someone actually brings you a customer, and your happiest users often turn into your best promoters. Choosing the right affiliate software for SaaS is what turns that potential into predictable, repeatable growth.
The tricky part is choosing the software. SaaS has needs that generic affiliate tools miss: recurring commissions, clean billing sync, accurate tracking that survives ad blockers, and a real plan for paying affiliates around the world.
This guide compares 8 of the best affiliate software platforms for SaaS in 2026. We look at pricing, features, payouts, and tax handling, so you can find the one that fits how you work. Every tool here has genuine strengths, and we will be honest about the trade-offs too.
TL;DR: the top 3 for most SaaS teams
- Rekomi is the best all-in-one. It tracks referrals, pays your affiliates for you, and handles their tax forms, starting at $19/mo.
- Rewardful is the simplest pick if you bill on Stripe or Paddle and want a clean, fast setup.
- FirstPromoter is great for teams that want deep SaaS analytics like MRR and churn alongside their program.
Why affiliate marketing works so well for SaaS
Before the tools, it helps to know why this channel suits SaaS in particular.
- It is low risk. You pay commissions only after a real customer signs up, so your cost is tied directly to results.
- It rewards recurring revenue. With subscriptions, an affiliate can earn on every renewal, which keeps them motivated to send you customers who stick around.
- It scales with trust. People believe recommendations from creators, consultants, and other founders far more than ads.
- It compounds. Each new affiliate becomes a small, ongoing growth channel, and good programs grow quietly in the background.
For B2B SaaS especially, partners like agencies, consultants, and integration providers can become some of your highest-quality referral sources. The right software makes all of this easy to run.
What to look for in affiliate software for SaaS
Not all affiliate tools are built with subscriptions in mind. As you compare options, weigh these factors:
- Recurring commission tracking. Your revenue renews monthly, so your software should track and pay on renewals, upgrades, and downgrades, not just the first sale.
- Billing integration. A direct Stripe or Paddle connection keeps commissions accurate and saves you manual reconciliation.
- Reliable tracking. First-party tracking and custom domains hold up far better than old-school third-party cookies, which browsers and ad blockers increasingly block.
- Payouts. Some tools only track commissions and leave you to pay every affiliate by hand. Others pay them for you, which saves real time as you grow.
- Tax handling. If you pay affiliates, you may need W-9 and W-8 forms and year-end filing. Built-in handling removes a compliance headache.
- Affiliate program management. Look for clean dashboards, approval controls, fraud protection, and an easy portal your affiliates will actually enjoy using.
- Recruitment help. A few platforms include a network or marketplace so affiliates can discover you, not just the other way around.
- Fair, predictable pricing. Check the entry price, what is locked behind higher tiers, and any fees on payouts or tracked revenue.
A quick tip: list your top three must-haves before you start comparing. It keeps you focused on what matters for your stage rather than chasing the longest feature list.

The 8 best affiliate software platforms for SaaS
1. Rekomi
Rekomi is an all-in-one affiliate, referral, and partner platform built for SaaS. What sets it apart is that it does not stop at tracking: it also pays your affiliates for you and handles their tax forms, so the whole program runs in one place.
Best for: SaaS teams that want tracking, payouts, and tax compliance handled together, without paying affiliates by hand or chasing paperwork.
Pricing: Starts at $19/mo (Starter), with Growth at $39/mo and Pro at $99/mo, plus a 14-day free trial. Instead of charging a fee on all your revenue, Rekomi takes a flat 3% on affiliate payouts (2.5% on Enterprise), and that take only applies when affiliates actually earn.
Standout features:
- Done-for-you payouts through Stripe Express, so affiliates onboard once and get paid automatically
- Built-in tax-form collection (W-9, W-8BEN, W-8BEN-E) and year-end handling, included rather than an add-on
- First-party tracking with custom domains that stand up to ad blockers
- A free branded affiliate portal on your own subdomain, even on the starter plan
- All commission models, including recurring, one-time, percentage, and flat
- One-click migration from 6 platforms, so switching is easy
- Modern extras like an AI co-pilot that turns customers into affiliates and a hosted server for AI tools
Payouts and tax: This is Rekomi’s biggest edge. Most tools make you pay affiliates and gather tax forms yourself, or charge extra for it. Rekomi builds both into the platform. PayPal payouts are rolling out to join the live Stripe Express rail.
Reviews: As a newer platform, Rekomi has fewer public reviews than the veterans, so the best way to judge it is the free trial and how well it fits your workflow.
Keep in mind: Because pricing includes a take-rate on payouts, very high-volume programs may want to compare it against a pure flat-fee tool. Payouts also run through Rekomi by design, which is what makes the all-in-one model work, so it is less suited to teams who want to pay affiliates entirely their own way.
Bottom line: If you want the least operational work, where tracking, payouts, and tax all live together at a low starting price, Rekomi is the strongest all-in-one choice for SaaS.
2. Rewardful
Rewardful is a long-time favorite for SaaS founders who bill on Stripe or Paddle. It is known for a fast, no-code setup and accurate recurring-commission tracking that reads straight from your billing data.
Best for: Stripe or Paddle SaaS teams that want a simple, dependable program up and running quickly.
Pricing: Starts at $49/mo (Starter), with Growth at $99/mo and Enterprise from $149/mo, plus a 14-day trial. There is no fee on the subscription itself.
Standout features:
- One-click Stripe and Paddle setup with no developer work
- Accurate tracking of renewals, upgrades, and cancellations
- First-party cookie tracking
- Coupon-code tracking for influencers
- A branded affiliate portal with a custom domain on higher tiers
Payouts and tax: You can pay affiliates yourself via PayPal and Wise at no Rewardful fee, or use its newer Managed Payouts service, which adds tax-form collection and year-end filing for a 3% fee.
Reviews: Well regarded on G2 and Capterra, with reviewers consistently praising its ease of setup and responsive support.
Keep in mind: It is built specifically for Stripe and Paddle, so it is not the right tool for large ecommerce catalogs. Tax handling and fully managed payouts come at the extra 3% rather than being included.
Bottom line: A safe, polished choice for Stripe-based SaaS that values simplicity and speed.
3. FirstPromoter
FirstPromoter is built for SaaS teams that love data. Alongside the usual affiliate features, it surfaces metrics like MRR and churn so you can see how your program affects real subscription revenue.
Best for: Data-driven SaaS teams that want analytics depth.
Pricing: Starts at $49/mo, with a 14-day trial. Higher tiers scale with the revenue you track.
Standout features:
- Deep SaaS metrics including MRR and churn
- Integrations with Stripe, Paddle, Chargebee, and more
- Flexible commission rules and rewards
- One-click managed payouts
- Fraud detection tools
Payouts and tax: It offers managed payouts and supports tax-form handling, which is a real plus for a tool at this price.
Reviews: Strong ratings on G2 and Capterra, with analytics depth often called out as a highlight.
Keep in mind: Some features, like custom domains and certain automations, have historically sat on higher tiers, so check that your must-haves are on the plan you want.
Bottom line: Pick FirstPromoter if program analytics and subscription insight matter as much as the affiliate features themselves.
4. Tapfiliate
Tapfiliate is a flexible platform that works for both SaaS and ecommerce. If you run more than one type of program, its adaptability is a strength.
Best for: Teams that want one tool across SaaS and ecommerce, with room to customize.
Pricing: Starts at $89/mo billed monthly, with a lower effective rate on annual billing, plus a free trial.
Standout features:
- Affiliate, referral, and influencer programs in one place
- Multiple programs with different rules
- A customizable affiliate portal
- A wide range of integrations
- Detailed reporting
Payouts and tax: Payouts and tax forms are handled through its Trolley integration rather than fully native, which works well but is an extra piece to set up.
Reviews: Solid ratings overall, with flexibility and integrations frequently praised.
Keep in mind: Lower tiers have caps on clicks and conversions with overage fees, and deeper customization can need some hands-on setup.
Bottom line: A solid, flexible choice, especially if you run both SaaS and ecommerce programs.
5. Partnero
Partnero stands out for letting you run affiliate programs and customer referral programs side by side, which is handy when you want both word-of-mouth and partner growth.
Best for: Teams that want affiliate and referral programs together.
Pricing: Starts at $49/mo billed annually, with a generous 30-day trial.
Standout features:
- Affiliate, referral, and even newsletter referral programs
- Clean, customizable portals
- Stripe and Paddle integrations
- Flexible commission options
- Built-in payouts
Payouts and tax: Partnero pays affiliates and supports tax-form handling. Self-managed PayPal and Wise payouts are free; its optional managed-payout service costs 7%.
Reviews: Highly rated by its users, with a smaller but enthusiastic review base as it grows.
Keep in mind: It is growing fast, so a few advanced features are still maturing compared with older tools.
Bottom line: A strong all-rounder, and a great pick if referrals and affiliates both matter to you.
6. Tolt
Tolt is a newer, modern affiliate platform that has earned fans for its clean design and quick setup. It focuses on doing the core SaaS affiliate job well, without clutter.
Best for: Teams that want a simple, modern, good-looking tool.
Pricing: Starts at $69/mo (Basic), with a 14-day trial.
Standout features:
- A polished, easy-to-use interface
- Fast Stripe-native setup
- Recurring commission tracking
- A branded affiliate portal
- Affiliate payouts and tax handling from the Growth plan
Payouts and tax: Tolt’s automated payouts and tax forms come in from the Growth plan; the Basic plan is manual payouts only, and automated payouts carry a 2% fee.
Reviews: Early reviews are very positive, especially on design and ease of use, though it has fewer total reviews than older tools.
Keep in mind: As a younger tool, its feature set is leaner than the veterans, which is part of the appeal but worth knowing if you need advanced options.
Bottom line: A great fit if you value a clean, modern experience and want to launch fast.
7. Reditus
Reditus is a B2B SaaS affiliate platform with a twist: it includes a marketplace where you can be discovered by affiliates already looking to promote SaaS tools.
Best for: B2B SaaS teams that want help finding new affiliates, not just managing them.
Pricing: Starts at $99/mo (Startup), with a free trial.
Standout features:
- A B2B affiliate marketplace for discovery
- Stripe integration and recurring tracking
- A self-serve affiliate experience
- Lead and commission tracking
- A public listing to attract partners
Payouts and tax: Reditus handles affiliate payouts, though automated payouts carry a processing fee (about 5% by card, 2% by invoice). It does not handle tax forms, so you will manage that side yourself.
Reviews: Positive reviews within its B2B niche, with the marketplace often cited as the main draw.
Keep in mind: The marketplace is most valuable for B2B tools, and the lack of tax handling is a gap if compliance is a priority.
Bottom line: Choose Reditus when affiliate discovery is your main challenge and you want a built-in audience of B2B promoters.
8. PartnerStack
PartnerStack is the enterprise option. It is a full partner ecosystem platform with a large B2B network, built for companies running affiliate, referral, and reseller programs at scale.
Best for: Funded B2B SaaS building a serious, multi-type partner program.
Pricing: Custom, quote-only pricing, typically aimed at larger budgets. You book a demo to get numbers.
Standout features:
- A large B2B partner network for recruiting
- Affiliate, referral, and reseller programs together
- Robust automation and workflows
- Strong reporting and partner management
- Built-in payouts and tax handling
Payouts and tax: PartnerStack pays partners and handles tax forms, as you would expect at the enterprise level.
Reviews: Strong, high-volume ratings on G2, especially from larger B2B SaaS teams.
Keep in mind: It is the most expensive option here and can be more than a small team needs. Setup is more involved, and pricing is not public.
Bottom line: The right call for larger B2B SaaS companies that want a complete partner ecosystem and have the budget to match.
How to find affiliates for your SaaS
Great software is only half the job; you also need people to promote you. A few proven ways to recruit affiliates:
- Start with your customers. Your happy users already love the product, so invite them first. Some tools, like Rekomi, even have an AI co-pilot that helps turn customers into affiliates.
- Reach out to creators and consultants in your space who already talk to your audience.
- Use a network or marketplace. Platforms like Reditus and PartnerStack let affiliates discover you, and Rekomi includes network access so your program can be found.
- Make joining easy. A clean, branded signup page and a simple portal lower the barrier for new affiliates.
If you are wondering how to find affiliates for a B2B SaaS product specifically, focus on partners with aligned audiences: agencies, integration partners, and industry consultants tend to convert best.
How to choose the right one for you
There is no single best tool, only the best fit for your situation. A few quick guides:
- You are a solo founder or early-stage: Start where the entry price is low and the work is minimal. Rekomi ($19/mo, with payouts and tax handled) or Rewardful are easy first programs.
- You bill on Stripe and want the simplest setup: Rewardful or Tolt.
- You care most about analytics: FirstPromoter.
- You want payouts and tax fully handled for you: Rekomi keeps it all in one place and included in the price.
- You run both SaaS and ecommerce, or affiliate and referral: Tapfiliate or Partnero.
- You need help finding affiliates: Reditus for its B2B marketplace.
- You are enterprise: PartnerStack.
Common mistakes to avoid
A little care up front saves a lot of cleanup later. Watch out for these:
- Ignoring payouts and tax. Tracking is easy; paying affiliates across countries and handling forms is the part that eats your time. Decide early whether you want that handled for you.
- Picking on price alone. A cheap tool that makes you pay every affiliate by hand can cost more in hours than a slightly pricier all-in-one.
- Overlooking tracking quality. If your tracking misses sales, affiliates lose trust and stop promoting you. First-party tracking matters.
- Setting commissions you cannot sustain. Model your margins first, especially for recurring commissions that pay out for the life of a customer.
- Making it hard to join. Friction at signup quietly kills programs. Keep onboarding simple.
Frequently asked questions
What is affiliate software for SaaS?
It is a tool that tracks who refers new customers to your SaaS, calculates commissions on those sales (including recurring ones), and helps you manage and pay your affiliates. Good SaaS-focused software connects to your billing so commissions stay accurate over time.
What is the difference between affiliate software and an affiliate program?
Your affiliate program is the offer itself: the commissions, rules, and partners. Affiliate software is the platform that runs it, handling tracking, dashboards, and payouts. You design the program, and the software powers it.
How much does affiliate software for SaaS cost?
Entry plans usually run from about $19 to $99 per month. Some tools also charge a fee on payouts or the revenue they track, and enterprise options are custom-priced. Rekomi starts at $19/mo and takes 3% on affiliate payouts only when affiliates earn.
Do these tools pay my affiliates for me?
Some do and some do not. Rekomi, FirstPromoter, Tolt, Partnero, and PartnerStack offer built-in or managed payouts. Rewardful and Tapfiliate handle payouts through self-managed options or an add-on or integration. Always check whether tax forms are included too.
What about taxes and 1099 forms?
If you pay affiliates, you may need to collect tax forms and file year-end documents. Rekomi includes tax-form collection and handling in its pricing. Others, like Rewardful, offer it as a paid add-on, and a few do not handle it at all, so confirm before you launch.
How do I find affiliates for my SaaS?
Start with your existing customers, reach out to creators and consultants in your niche, and consider a tool with a built-in network or marketplace so affiliates can find you. For B2B SaaS, agencies and integration partners are often your best source.
How do I start a SaaS affiliate program?
At a high level: set your commission and rules, pick your software, create a signup page, recruit your first affiliates, and track results. If you want the full walkthrough, see our guide on how to start a SaaS affiliate program.
