Affiliate Tracking Software for Sellers: Rewardful vs FirstPromoter vs Tapfiliate vs PartnerStack (2026)

This guide is for the other side of affiliate marketing: you sell a SaaS product or digital product, and you want to start paying other people to refer customers to you. The four tools below all track referrals and pay your affiliates — but they meter the bill in completely different ways, and that difference matters more than the feature lists.

Last updated: November 2026 · Prices in USD, checked against vendor pricing pages in November 2026 · How we compare: this guide is based on publicly available vendor information, not hands-on testing. We have not run a live affiliate program on these tools for this review, and there are no paid placements.

Affiliate Disclosure: Some links on this page are affiliate links. If you sign up through them, we may earn a commission from the vendor at no extra cost to you. This is how the site is funded. It does not change which products we include or the facts we publish — every price and feature below is taken from the vendors' own public pages. One clarification that matters on this topic: any commission you pay your affiliates is set by you, inside whichever tool you choose. That rate is your business decision, not something this site receives or influences.

Prices are USD, before tax, as published by the vendors in November 2026 (Prices checked November 2026). Annual billing lowers several of these: Rewardful and FirstPromoter charge 10 months for a year, and Tapfiliate's annual rates are shown in the table. None of the figures above include the commissions you choose to pay your own affiliates, or your payment processor's fees — those are separate and usually larger. Plans change — always confirm the current price and limits on the vendor's site before you buy.

What the software actually costs at three program sizes

The headline monthly price is the least informative number on these pricing pages, because each tool raises it on a different trigger. The table below is simple arithmetic on the published prices above: monthly billing for 12 months, software fees only. It excludes the commissions you pay your affiliates (you set those, and you would owe them on any tool) and your payment processor's fees.

Affiliate-driven revenueRewardfulFirstPromoterTapfiliate
$2,000/month (just launched)Starter: $49 × 12 = $588/yearStarter: $49 × 12 = $588/yearLaunch: $89 × 12 = $1,068/year ($888 billed annually), assuming an average referred order of $50 — about 40 conversions, inside the caps
$10,000/month (program is working)Growth: $99 × 12 = $1,188/year — the $7,500 ceiling pushes you upBusiness: $99 × 12 = $1,188/year — the $5,000 ceiling pushes you upStill Launch: $1,068/year if you stay within 50 affiliates and 500 conversions (about 200 conversions at a $50 average) — revenue alone does not move this price
$40,000/month (scaling)Enterprise starts at $149/mo but its entry tier covers up to $30,000 — so $1,788/year is a floor, not the total; the tier above is not publishedEnterprise from $149/mo — again, $1,788/year is a floorScale: $179 × 12 = $2,148/year ($1,788 billed annually), assuming conversions stay within 10,000/month

The percentage-fee fork. Among these four, the only published "low monthly price plus a percentage" offer is PartnerStack Spark: $0/month plus 10% of the commissions you pay out. Set that against a $49/month flat plan and the break-even is exact: 10% of payouts equals $49 when you pay out $490/month to affiliates. Below $490/month in payouts, Spark is the cheaper software bill; above it, the flat $49 plan is cheaper — and Spark also excludes recruiting from the PartnerStack network, so the comparison is never price alone. The same lens applies inside Rewardful: its optional Managed Payouts at 3% of payouts means fully automating $1,000/month of affiliate payouts costs $30/month on top of your plan, versus $0 if you send PayPal or Wise payouts yourself.

How to read a small program's real burden. At $500/month of affiliate-driven revenue, a $49 tool is already 9.8% of that revenue in software fees alone, before the commissions you set and processor fees. "Only $49 a month" is only cheap relative to a program that is already producing. Conversely, at launch the revenue ceilings of Rewardful and FirstPromoter are rarely the binding constraint — your billing provider and whether you can recruit anyone at all will decide things first.

The four tools in detail

Rewardful — for SaaS that bills on Stripe and wants to launch this week

Rewardful is affiliate and referral tracking built specifically around Stripe: connect your Stripe account and it follows referred customers through trials, upgrades, downgrades, cancellations and refunds, adjusting commissions to match, with a two-way sync that surfaces affiliate data inside Stripe itself. Paddle is the only other billing platform supported. Starter ($49/mo) covers up to $7,500/mo in affiliate-attributed revenue with unlimited affiliates but just 1 campaign and 2 team members. Growth ($99/mo) raises the ceiling to $15,000 and adds unlimited campaigns, a branded affiliate portal, custom domain and private campaigns. Enterprise (from $149/mo) starts at up to $30,000/mo on its entry tier. Every plan charges a 0% transaction fee, annual billing costs 10 months, and there is a 14-day trial. One caution from the vendor's own ecosystem: multiple sources describe the Paddle support as Paddle Classic only, so if you bill through Paddle Billing, verify before you commit.

STRENGTHS (per published specs)

  • Deepest Stripe fit of the four, including two-way sync into the Stripe dashboard
  • 0% transaction fee at every tier — the price is the subscription, full stop (unless you opt into Managed Payouts)
  • Unlimited affiliates from the cheapest plan; you are metered on results, not headcount

TRADE-OFFS

  • Stripe or Paddle only — any other billing setup rules it out entirely
  • The better your program works, the sooner you are moved up a tier; budget for Growth, not Starter
  • No marketplace: Rewardful tracks and pays affiliates you recruit yourself
See Rewardful plans

FirstPromoter — for subscription businesses whose billing is not (only) Stripe

FirstPromoter runs affiliate, referral and influencer programs for subscription businesses, and its defining choice is breadth of billing integrations: it reads billing events natively from Stripe, Paddle, Chargebee, Recurly and Braintree, so commissions follow renewals, upgrades, refunds and cancellations in whichever system actually charges your customers. Commission structures are the most flexible of the self-serve three: percentage or flat, recurring or lifetime, tiered rates, multi-tier commissions up to three levels, and double-sided rewards. Starter ($49/mo) covers up to $5,000/mo in affiliate-driven revenue, 1,000 affiliates and 3 campaigns. Business ($99/mo) covers up to $15,000 and lifts the affiliate and campaign caps. Enterprise (from $149/mo) covers programs above that. The pricing page lists no fee on payouts, and the 14-day trial needs no card.

STRENGTHS (per published specs)

  • Five native billing providers — the widest coverage here for subscription tracking
  • Commission design (tiered, multi-level, per-plan rates, cost-per-lead) goes furthest of the self-serve tools
  • Same $49 entry point as Rewardful, with no payout fee listed

TRADE-OFFS

  • Starter's $5,000/mo revenue ceiling is the tightest here — a program that works will leave this tier fast
  • No marketplace or partner discovery: recruitment is entirely on you
  • Depth of commission rules means more setup decisions before you can launch
See FirstPromoter plans

Tapfiliate — for sellers whose sales do not all happen in one billing system

Tapfiliate is the generalist of the four: 30+ pre-built integrations (Shopify, WooCommerce, BigCommerce, Stripe and more) plus a JavaScript pixel, REST API and server-to-server postback tracking, so a store, a subscription product and a landing page can feed one affiliate program. Its pricing logic is also the odd one out — a flat subscription with no percentage of sales, where the tiers are fenced by usage instead of revenue. Launch ($89/mo, $74/mo billed annually) allows 50 affiliates, 1 program, 5,000 clicks and 500 conversions a month, with overage billed per extra 1,000 clicks or conversions. Scale ($179/mo, $149/mo billed annually) raises those to 150 affiliates, unlimited programs, 100,000 clicks and 10,000 conversions, and adds multi-level commissions and automated payouts. Enterprise is custom. High-ticket digital products, which generate few conversions per dollar of revenue, can stay on Launch far longer than the revenue figures alone would suggest.

STRENGTHS (per published specs)

  • Revenue growth does not raise your software bill — only usage counts do
  • One program can track store orders and subscription sales side by side
  • Flat pricing is the easiest of the four to forecast a year ahead

TRADE-OFFS

  • Most expensive entry point here ($89/mo monthly billing) before you have proven the channel
  • Launch's 50-affiliate and 500-conversion caps are a different kind of ceiling — low-ticket, high-volume products hit them early, plus overage
  • Recruitment help means inviting your own customers; there is no managed B2B partner network behind it
See Tapfiliate plans

PartnerStack — for B2B SaaS buying a partner ecosystem, not just tracking

PartnerStack is a partner relationship management platform for B2B software companies: affiliate, referral, reseller, co-sell and influencer programs in one system, with partner onboarding, enablement, lead and deal registration, CRM integrations and automated payouts. Its decisive difference from the other three is the Marketplace — a network of more than 100,000 active B2B partners (the vendor's own pages cite figures in the 117,000+ range) who can discover and apply to your program, instead of you recruiting every partner yourself. The trade is transparency and weight: the main platform's Launch, Growth and Enterprise plans publish no prices at all — pricing is based on program size, feature needs and support level, and is confirmed during a demo, with guided onboarding on every plan. Separately, Spark is a self-serve entry point at $0/month plus 10% of the commissions you pay out, with simple Stripe sale tracking — but Spark accounts explicitly cannot recruit from the PartnerStack network, so it is not a cheap way into the marketplace.

STRENGTHS (per published specs)

  • The only real answer here to "we have no affiliates yet" — a B2B partner marketplace plus recruitment tooling
  • Covers partner types the trackers do not: resellers, co-sell and deal registration alongside affiliates
  • No cap on partner count, and Spark gives a $0-subscription way to test simple referral tracking

TRADE-OFFS

  • No published pricing for the main platform — you cannot budget or compare totals without a sales process, and any payout fee is settled in that process too
  • Guided implementation measured in weeks is a different commitment from a 14-day self-serve trial
  • For a single affiliate program run by a small team, most of the platform is capacity you will not use

How to choose in four steps

STEP 1

Start with your billing provider, not features

Tracking lives or dies on the connection to whatever charges your customers. Stripe-only narrows you to all four; Chargebee, Recurly or Braintree points to FirstPromoter; Shopify or WooCommerce orders point to Tapfiliate; anything outside a tool's list rules that tool out completely, however good its dashboard looks.

STEP 2

Decide who recruits the affiliates

Rewardful, FirstPromoter and Tapfiliate are tracking and payout infrastructure: the partners have to come from your audience, customers and outreach. If your plan depends on a network finding partners for you, that is PartnerStack's marketplace — and the main reason to accept its quote-only pricing.

STEP 3

Price the year at your size, not the entry month

Run your expected affiliate revenue through each ladder before you compare: revenue-metered tools step up as you succeed, Tapfiliate steps up on headcount and conversions, and percentage offers step up with every payout. Then add the cost nobody lists first: the commissions you will set, which dwarf the software fee on any working program.

STEP 4

Trial with ugly billing events, not a clean signup

Use the 14-day trials to push a referred test customer through a trial period, an upgrade, a downgrade and a refund. That sequence — not the first click — is where affiliate tracking breaks, and it is exactly what the billing-synced tools claim to handle. PartnerStack's equivalent check happens in the demo: ask what the full first-year cost is, including any fee on payouts.

FAQ

What exactly am I paying for with affiliate tracking software?

Three jobs: attributing a customer to the affiliate who referred them, calculating the commission you owe under the rules you set, and running the payouts and affiliate-facing portal. You are not paying for the commissions themselves — those are set by you and paid to your affiliates on top of the software fee, along with your payment processor's charges. None of these tools changes what your product earns; they administer the program you design.

Will one of these tools bring me affiliates and sales?

With one partial exception, no — and any tool that implied otherwise would be overselling. Rewardful, FirstPromoter and Tapfiliate assume you recruit your own partners from your customers and audience. PartnerStack's marketplace is the exception: partners can discover your program there, though the vendor's own materials still frame results around active program management, not the listing alone. No tool on this page guarantees referred revenue.

Why does PartnerStack not publish its price?

Its pricing page states that pricing is based on partner program size, feature needs and level of support, with the final plan confirmed during a demo. That is why this guide lists it as quote-only rather than repeating third-party estimates as if they were vendor prices. PartnerStack does publish one price: Spark, its self-serve entry tier, is $0/month plus 10% of the commissions you pay out — but Spark cannot recruit from the PartnerStack network.

Which is the cheapest way to start a first program?

On published prices, Rewardful and FirstPromoter both start at $49/mo with 14-day trials, and that buys a real program if your billing setup fits. Spark's $0 subscription is cheaper still while your monthly payouts to affiliates stay under about $490 (where its 10% payout fee reaches $49), but it is a lighter tool with no network recruiting. The honest catch at this scale: the software fee is the small part — your time recruiting partners is the real cost of a first program.

I searched for a "Rewardful alternative" — what actually differs among the alternatives?

Usually one of three things. Billing coverage: FirstPromoter adds Chargebee, Recurly and Braintree to Rewardful's Stripe/Paddle pair. Pricing meter: Tapfiliate charges by affiliates, clicks and conversions instead of affiliate revenue, so its bill does not rise when your referred sales do. Scope: PartnerStack adds a recruiting marketplace and reseller/co-sell programs, at quote-only pricing. If none of those is your reason for switching, the honest answer is that the tools overlap heavily and the switch may not change your results.

Why are there no hands-on scores or "we tested it" claims here?

Because this guide is compiled from the vendors' published specifications and pricing, not from running live programs on each platform. Where a judgment appears — for example, that a $49 fee is 9.8% of a $500/month program's referred revenue — it is arithmetic on published numbers, shown with its working so you can redo it with your own figures.
