For a solo founder selling digital downloads, I’d separate the choice into two cases:

My shortlist

LemonSqueezy Lemon Squeezy Docs Rewardful FirstPromoter### What I'd choose as a solo founder

If you're just starting and revenue is relatively low: Lemon Squeezy.

You don't pay a monthly subscription for ecommerce, and it handles digital downloads, payments, and sales-tax/VAT compliance. Its standard transaction fee is 5% + $0.50, with an additional 3% on affiliate-referred orders. LemonSqueezy Lemon Squeezy Docs Lemon Squeezy Docs

So, for example, on a $30 digital product sold through an affiliate:

• Lemon Squeezy base fee: $2.00
• Affiliate platform fee: $0.90
• Affiliate commission, say 30%: $9.00
• You retain roughly $18.10 before other applicable costs/taxes

That's considerably easier to stomach when you're doing only a handful of sales per month because there's no $49 monthly bill.

Once affiliate sales become substantial, Rewardful becomes interesting. It charges $49/month on its Starter plan and 0% transaction fee, with the plan covering up to $7,500/month in affiliate-attributed revenue. Rewardful

The catch is that Rewardful is particularly designed around Stripe/recurring-billing businesses, although it does support one-time Stripe charges. Rewardful Help Center Rewardful Help Center

The break-even consideration

If you're already using Stripe, I'd think about it this way:

Rewardful: $49/month regardless of affiliate sales
Lemon Squeezy: no monthly fee, but takes an additional 3% of affiliate-referred orders.

Ignoring Lemon Squeezy's normal payment/platform fee for a moment, the 3% affiliate surcharge reaches $49 when you have about $1,633/month in affiliate-attributed sales.

So if you're doing $500/month from affiliates, Lemon Squeezy's extra affiliate fee is only ~$15.

If you're doing $5,000/month from affiliates, that 3% is ~$150/month, making a fixed-fee affiliate platform much more attractive.

One important distinction

If by "referral" you mean customers referring friends rather than recruiting affiliates/influencers, I'd look at this somewhat differently. You can often structure a simple referral program with a discount/reward rather than paying for a full affiliate-management platform.

If you tell me (1) what you use to sell the downloads now (Gumroad, Shopify, Stripe, WooCommerce, your own site, etc.), (2) your typical product price, and (3) roughly how much you expect to sell per month, I can calculate the actual fees for 3–5 options and tell you where the break-even points are.

For a solo founder selling digital downloads, I’d look at Referralful first if your checkout is Stripe: it starts at $19.99/mo, has 0% transaction fees, and includes unlimited affiliates/clicks. Referralful

Other options:

• FirstPromoter — $49/mo, 0% transaction fee; more established. FirstPromoter
• Rewardful — $49/mo, 0% transaction fee, but primarily SaaS/Stripe-oriented. docs.affitor.com
• Lemon Squeezy — useful if you want checkout + merchant-of-record together, but affiliate referrals add 3% on top of its platform fee. docs.lemonsqueezy.com

For low/early revenue, Referralful is the cost-conscious choice.

If you’re a solo founder selling digital downloads, I’d avoid platforms that take a percentage of every sale. A flat monthly fee is usually much cheaper once you have any meaningful affiliate volume.

My shortlist

Current published pricing puts FirstPromoter at $49/month for up to $5k/month in affiliate revenue, Rewardful at $49/month for up to $7.5k, and Tolt at $69/month for up to $10k. FirstPromoter Referly Affitor

For your situation, I'd look first at FirstPromoter or Rewardful.

• Rewardful — particularly attractive if your checkout is Stripe or Paddle. Its $49 plan has a $7,500/month affiliate-revenue limit and explicitly advertises a 0% transaction fee. Referly
• FirstPromoter — $49/month, up to $5,000/month in affiliate revenue, and supports Stripe, Paddle and Chargebee. Its pricing page doesn't state a transaction fee. FirstPromoter
• Tolt — worth considering if you expect to grow past $7.5k/month in affiliate sales fairly quickly, but automated payouts carry a 2% fee on applicable plans. Affitor
• Affitor — interesting if you're very early because there's no monthly subscription until you hit $10k in affiliate revenue, but then it takes 3.5% of affiliate-driven sales. Affitor

One important wrinkle for digital downloads

The checkout platform matters more than the affiliate platform. If you're selling PDFs, templates, ebooks, courses, presets, Notion templates, etc., tell me what you're using for checkout—Gumroad, Lemon Squeezy, Shopify, WooCommerce, Stripe, Payhip, Podia, etc.

I can then narrow it down to the 2–3 cheapest options for your exact setup, including what you'd actually pay at, say, $1k / $5k / $10k monthly sales.

For a solo founder selling digital downloads, I would avoid expensive affiliate networks and prioritize platforms with either:

• a flat monthly fee
• 0% revenue share
• easy setup (Stripe, Lemon Squeezy, Gumroad, Shopify, etc.)
• simple affiliate links + coupon tracking

The best choice depends on your sales volume and checkout stack.

My shortlist

What I’d pick by situation

If you make <$1k/month from affiliates

Use something with almost no fixed cost:

• Referralful — attractive because it starts free and avoids revenue-share fees. Referralful
• Or even start manually with coupon codes + a spreadsheet if you only have a handful of affiliates.

If you expect affiliates to become a serious channel

Use a flat-fee tool:

• Partli — $29/mo and no percentage cut is appealing for a growing creator business. Partli
• FirstPromoter — a more established option if you use Stripe/Paddle. Affitor Docs

If you sell through Gumroad, Lemon Squeezy, Shopify, etc.

Your checkout matters more than the affiliate tool. Some affiliate platforms integrate deeply with certain payment systems, so pick based on where your digital downloads are sold.

Platforms I would probably avoid as a solo founder

• Enterprise partner platforms like PartnerStack or impact.com — usually built for larger companies and can be expensive. Affitor Docs
• Anything taking 5–10%+ of every affiliate sale forever unless it brings you a marketplace of affiliates you cannot reach yourself.

My recommendation

For a typical solo creator selling PDFs, templates, courses, presets, plugins, or other downloads:

1. Starting out: Referralful or Partli
2. Making consistent affiliate revenue: FirstPromoter
3. High volume: move to a flat-fee system where you keep 100% of affiliate-attributed revenue

A useful rule: if you expect affiliates to generate more than ~$2k–$5k/month, avoid percentage-of-revenue pricing because the software bill can grow faster than the value you receive.

If you tell me what you sell (templates, ebooks, courses, software, etc.) and your checkout platform (Gumroad/Lemon Squeezy/Stripe/Shopify/etc.), I can narrow it to the best 1–2 options.

If you're a solo founder selling digital downloads, I'd avoid the big affiliate networks and expensive SaaS affiliate platforms. You probably want something that:

• costs little or nothing before you have affiliate sales
• doesn't take a big percentage of every sale
• gives affiliates unique links/coupons
• handles tracking and payouts without you building it yourself

My shortlist

My pick for you: Lemon Squeezy if you're starting from scratch. It is specifically built for digital products, has no monthly ecommerce fee, handles payments and sales-tax obligations as merchant of record, and includes affiliate functionality. Its base transaction fee is 5% + $0.50, and affiliate-referred orders add 3%. LemonSqueezy Lemon Squeezy Docs

The important catch: the 3% affiliate fee is on top of the normal transaction fee. So it's not the cheapest once you're doing meaningful volume. Lemon Squeezy Docs

If you already have your own checkout

Then I'd look at FirstPromoter.

It's currently $49/month for up to $5,000/month in affiliate revenue, with no additional transaction percentage listed. FirstPromoter

For example, if affiliates generate $5,000/month:

• FirstPromoter: $49/month
• Lemon Squeezy's affiliate fee alone: $150/month
• Plus Lemon Squeezy's normal transaction fees

So FirstPromoter becomes considerably more attractive once you're getting real affiliate volume.

What I'd do in your situation

Under ~$1,000/month in affiliate-driven sales:
Use Lemon Squeezy. Don't pay $49/month just to have an affiliate system.

$1,000–$3,000/month:
Still probably Lemon Squeezy for simplicity, unless you're already using Stripe/another checkout.

$3,000–$10,000+/month:
I'd seriously consider FirstPromoter or another flat-fee affiliate tracker. At that point, avoiding a percentage-of-revenue fee matters.

There's also an interesting newer pay-as-you-grow option, Affitor, which currently advertises $0/month and a 3.5% fee only after the first $10,000 of affiliate-generated revenue. I'd treat that as a promising budget option rather than my default recommendation, since it's a newer product. Affitor Documentation

One other important distinction: if by "referral" you mean customers referring friends rather than recruiting affiliates/influencers, I'd choose a somewhat different tool. For a digital-download business, I can give you the cheapest setup for both customer referrals + affiliates, including the actual math at $1k/$5k/$10k monthly sales.

If you’re a solo founder selling digital downloads, I’d optimize for low fixed cost + no percentage of every affiliate sale. You probably don’t want an affiliate platform taking another 2–5% on top of your payment processor.

My picks

Current 2026 pricing comparisons put LinkJolt at $19.99/month with 0% revenue fees, Rewardful at $49/month with 0%, and FirstPromoter at $49/month with no stated additional transaction fee. Affitor Documentation LinkJolt

What I'd do in your position

If you're already using Stripe: I'd start with LinkJolt.

At ~$20/month, you're not giving up a percentage of every sale. Its current integrations include Stripe, Lemon Squeezy, Gumroad and several other checkout systems, and its entry plan tracks up to $5,000/month in affiliate sales. LinkJolt

If you want the safest/more established choice: Rewardful. It's $49/month and advertises 0% transaction fees. The downside is that its entry tier caps affiliate-attributed revenue at $7,500/month. Affitor Documentation Builtplain

If you haven't chosen your checkout platform yet: I'd seriously consider Lemon Squeezy. It has affiliate functionality built in, so you don't need another SaaS subscription. However, affiliate-referred orders incur an additional 3% fee on top of its normal platform fee. Lemon Squeezy Docs Lemon Squeezy Docs

For example, on a $30 digital product with a 30% affiliate commission:

• Sale: $30
• Affiliate: $9
• Your gross before payment/platform costs: $21
• With a 3% affiliate-platform surcharge: another ~$0.90
• With a flat $20/month affiliate tool: essentially $0 extra per sale once you've covered the subscription.

That distinction becomes important as your affiliate sales grow.

One I'd avoid for your specific goal

Gumroad is wonderfully simple, but if your primary objective is keeping your take rate low, it's not my first choice. Its direct-sale fee is already substantial, and its affiliate functionality doesn't eliminate that underlying fee. Gumroad does let you set affiliate commissions from 1–75% and handles tracking/payouts for you. Gumroad

My ranking for a solo digital-download business:

1. 🥇 LinkJolt — best economics at low volume
2. 🥈 Rewardful — best established/simple option if $49/mo is fine
3. 🥉 FirstPromoter — good alternative to Rewardful
4. Lemon Squeezy — best if you want checkout + affiliate system together
5. Gumroad — best for absolute simplicity, not lowest fees

If you tell me what you're selling, your typical price ($10/$30/$100/etc.), where you currently take payment (Stripe/Gumroad/Lemon Squeezy/etc.), and roughly how many sales/month, I can calculate the actual dollars you'd keep with each option and tell you which is cheapest.

If you're already using Stripe: I'd start with LinkJolt.

At ~$20/month, you're not giving up a percentage of every sale. Its current integrations include Stripe, Lemon Squeezy, Gumroad and several other checkout systems, and its entry plan tracks up to $5,000/month in affiliate sales. LinkJolt

If you want the safest/more established choice: Rewardful. It's $49/month and advertises 0% transaction fees. The downside is that its entry tier caps affiliate-attributed revenue at $7,500/month.

If you haven't chosen your checkout platform yet: I'd seriously consider Lemon Squeezy. It has affiliate functionality built in, so you don't need another SaaS subscription. However, affiliate-referred orders incur an additional 3% fee on top of its normal platform fee.

For example, on a $30 digital product with a 30% affiliate commission:

For a solo founder selling digital downloads, I’d avoid platforms that take a permanent percentage of every sale unless they’re also handling checkout, taxes, affiliates, and delivery. Your best choice depends on whether you need just affiliate tracking or an all-in-one store + affiliate system.

Best low-cut options

My shortlist for your situation

1. Best overall: Payhip + built-in affiliates

If you sell:

• ebooks
• templates
• Notion packs
• PDFs
• design assets
• mini-courses

I’d start here. You avoid paying for a separate affiliate SaaS, and you only upgrade when revenue justifies it.

2. Lowest long-term cost: Stripe + Referralful (or similar)

If you already have your own website and checkout:

• You keep control of your customer relationship.
• Affiliates get tracking links.
• You avoid giving away 5–10%+ forever.

Referralful advertises a free setup period and then a low monthly plan with 0% payout fees. Referralful

3. Best if you expect affiliates to become a major channel: FirstPromoter / Rewardful

Worth considering when you have:

• dozens of affiliates
• recurring revenue
• higher-priced products ($100+)

For a $9–$49 download, the economics usually don’t justify expensive affiliate software.

What I would avoid as a solo creator

• Gumroad as your main business long-term — fantastic for starting, but a percentage cut compounds. Contra
• Enterprise affiliate platforms — overkill until you have significant volume.
• Anything charging both monthly fees + a percentage of affiliate-generated revenue unless it provides major value.

A practical setup I’d choose

For a first $0–$10k/month digital download business:

1. Store: Payhip or Lemon Squeezy
2. Affiliate commission: 30–50% (digital products have high margins)
3. Recruit: - newsletter creators
4. YouTubers
5. niche bloggers
6. community owners
7. Pay affiliates monthly through PayPal/Stripe

Once affiliates are driving meaningful revenue, move to a dedicated tracker.

If you tell me:

• your product price ($5, $29, $99, etc.)
• whether you already have a website/Stripe
• whether affiliates are one-time commissions or recurring

I can narrow it down to the cheapest setup.

If you're a solo founder selling digital downloads, I'd optimize for low fixed cost + zero/very-low percentage fee, because paying 10–20% of every affiliate sale can get expensive quickly.

My shortlist

Current 2026 comparisons put Rewardful at $49/month with a 0% transaction fee, while FirstPromoter is also $49/month and Tolt is $69/month. Referly Affitor

What I'd choose

If you're using Stripe: I'd start with Rewardful.

At $49/month and 0% of affiliate revenue, it's particularly attractive once you're generating meaningful affiliate sales. Its entry plan currently covers up to $7,500/month in affiliate-attributed revenue. Referly

If you're very early and don't want another $49/month bill: look at RefVenue or a revenue-based option like Affitor. Affitor has a $0 starting price and only charges 3.5% on affiliate-driven sales after the first $10k, which can make more sense while you're validating whether affiliates will actually generate sales. Affitor refVenue

One important caveat: if your digital downloads are already sold through Gumroad, Lemon Squeezy, or Podia, check their built-in affiliate functionality before paying for a separate platform. For a solo founder, eliminating another subscription is often more valuable than having sophisticated affiliate software. Framekit

My rule of thumb

• <$1k/month affiliate sales: don't pay $50–$100/month if you can avoid it.
• $1k–$5k/month: revenue-based or very cheap software can make sense.
• $5k+/month: a flat $49/month platform with 0% revenue cut becomes very attractive.
• $10k+/month: definitely avoid platforms taking 3–5%+ of every affiliate sale unless their extra functionality is genuinely valuable.

If you tell me where you currently sell the downloads (Gumroad, Shopify, Lemon Squeezy, Stripe, Etsy, your own site, etc.) and roughly your monthly sales, I can narrow this down to the cheapest 2–3 options for your exact setup.

My rule of thumb

For a solo founder selling digital downloads, I’d avoid big affiliate networks that take a percentage of every sale. You usually want either:

1. A flat monthly fee + 0% revenue cut, or
2. A small per-sale fee only when you make money

Here are the best fits:

My recommendation by stage

If you’re making <$2k/month

• Use your existing checkout platform’s built-in affiliate/referral tools if available.
• Otherwise, look at Anderro because the low monthly cost makes sense for testing affiliates. Anderro

If you’re using Stripe + your own website

• Pick Rewardful or Tolt.
• You keep your margins and pay affiliates only their commission.

If you want affiliates to actively discover and promote your products

• Consider a marketplace-style option, but expect tradeoffs. Some marketplaces bring traffic but take a larger revenue share.

What I’d avoid

• ❌ Platforms taking 10%+ of every sale forever just for affiliate tracking
• ❌ Enterprise affiliate networks like Impact.com unless you already have significant affiliate volume
• ❌ Paying $100+/month before you know affiliates can generate sales

For most solo founders, the sweet spot is:

Your own checkout + Stripe + Rewardful/Tolt/Anderro + 20–40% affiliate commission.

That way your affiliate only costs you when they actually bring revenue.

If you tell me what you sell (Notion templates, ebooks, design assets, courses, software, etc.) and what checkout you use (Gumroad, Lemon Squeezy, Stripe, Shopify, Payhip, etc.), I can narrow it to the best 1–2 options.

If you’re a solo founder selling digital downloads, I’d avoid platforms that take a percentage of every sale unless they’re free until you have meaningful revenue.

My shortlist

Current pricing comparisons put Rewardful and FirstPromoter at the low end of the paid market, while Tolt and Referly cost more. Affitor Documentation Referly

What I'd choose for you

If you're selling through Stripe: I'd pick Rewardful.

It's $49/month, has 0% transaction fees, unlimited affiliates, and a 14-day trial. The main catch is that the $49 plan covers up to $7,500/month in affiliate-generated revenue; after that, you move up a tier. Rewardful Rewardful Help Center

That's attractive for a solo founder because you're paying a predictable software fee rather than giving the platform a percentage of every sale.

If your digital downloads are low-volume right now, though, I would not immediately spend $49/month. I'd look at a pay-as-you-grow option such as Affitor, which currently has a $0/month starting tier and takes 3.5% only on affiliate-driven sales after the first $10k. Affitor Documentation Affitor Documentation

One important distinction

There are really two different costs:

1. Platform fee — what the affiliate software takes.
2. Affiliate commission — what you pay the person who referred the customer.

For example, with a $30 digital product and a 30% affiliate commission:

• Customer pays: $30
• Affiliate gets: $9
• You keep: $21
• Rewardful gets: $0
• Stripe/payment processing still applies.

So I'd prioritize 0% platform transaction fees, especially once you're doing meaningful volume.

My ranking for a solo digital-download business:

1. 🥇 Rewardful — best if Stripe + you're ready to spend ~$49/mo
2. 🥈 FirstPromoter — best alternative if you need more flexibility
3. 🥉 Affitor — best if you're still validating the affiliate channel and want minimal upfront cost
4. Referly — interesting if you sell through multiple commerce platforms
5. Tolt — good, but harder to justify for a very small solo operation

One caveat: Rewardful is primarily positioned around SaaS/subscription businesses, so your actual checkout platform matters a lot. Rewardful

If you tell me what you're using to sell the downloads (Gumroad, Lemon Squeezy, Shopify, WooCommerce, Stripe, Payhip, your own site, etc.) and roughly your monthly sales, I can narrow this down to the cheapest option for your exact setup, including the actual dollars you'd pay at $1k/$5k/$10k monthly revenue.

One important distinction

There are really two different costs:

For a solo founder selling digital downloads, I’d avoid platforms that take a percentage of every affiliate-driven sale on top of paying the affiliate. The best setup is usually:

1. A checkout platform with built-in affiliates (simplest)
2. A low-cost affiliate tracking tool connected to Stripe (best margins)
3. A self-hosted affiliate plugin (lowest long-term cost if you have a site)

Here are the options I’d shortlist:

My ranking for your situation:

🥇 Best overall: Payhip + affiliates

If you sell things like:

• Notion templates
• ebooks
• design assets
• spreadsheets
• presets
• guides
• downloadable files

Payhip is hard to beat because you don’t have to build checkout, file delivery, or affiliate tracking yourself. SellRamp

🥈 Best margin: Stripe + Referralful/Rewardful

If you already have:

• your own website
• Stripe checkout
• email list

A dedicated affiliate tool usually saves money because you pay affiliates their commission, but the software doesn’t take another percentage of each sale. Referralful advertises no payout transaction fees and a low entry price after affiliates join. Referralful

🥉 Best “I don’t want to deal with taxes”: Lemon Squeezy

For international digital sales, merchant-of-record platforms can be worth the fee because they handle sales tax/VAT complexity. The tradeoff is giving up some margin.

What I would avoid

• Gumroad if your main concern is margins. It is convenient, but the fee structure can get expensive as revenue grows.
• Enterprise affiliate platforms charging $100+/month before you have affiliates generating sales.

A simple rule:

• <$1k/month revenue: Payhip or Referralful
• $1k–$10k/month: Stripe + Rewardful/Referralful
• $10k+/month: Dedicated affiliate software + your own checkout

If you tell me:

1. what kind of downloads you sell (templates, ebooks, software, courses, etc.),
2. your current checkout (Stripe, Shopify, Gumroad, none), and
3. expected monthly sales,

I can narrow it to the cheapest setup.

If you tell me:

1. what kind of downloads you sell (templates, ebooks, software, courses, etc.),
2. your current checkout (Stripe, Shopify, Gumroad, none), and
3. expected monthly sales,

I can narrow it to the cheapest setup.

If you’re a solo founder selling digital downloads, I’d avoid expensive affiliate SaaS unless you already have meaningful affiliate revenue.

My picks

My recommendation: Lemon Squeezy if you want everything in one place; Referralful if you already use Stripe.

1. referralful.com — best economics

This is particularly attractive for a solo founder. It's free until your first affiliate joins, then starts at $19.99/month, with 0% transaction/payout fees. The Starter plan supports up to $7,500/month in affiliate-attributed revenue and unlimited affiliates/clicks. Referralful Referralful

The catch: it's built around Stripe, so it's best if you're already selling through Stripe rather than wanting a complete digital-download storefront.

2. lemonsqueezy.com — probably the simplest overall

For digital downloads, this is compelling because Lemon Squeezy handles checkout, payments, tax/VAT as merchant of record, and affiliates.

The base platform fee is 5% + $0.50 per transaction, with no monthly fee. Affiliate-referred orders add another 3%. LemonSqueezy Lemon Squeezy Docs

So, for example, on a $20 digital product with a 30% affiliate commission, you're roughly looking at:

• $20 sale
• $6 affiliate commission
• $1.50 platform fee (5% + $0.50, before applicable extras)
• $0.60 affiliate fee
• ~$11.90 remaining before taxes/payment-specific extras

That's quite reasonable for a solo creator, especially because you aren't paying $50–$100/month before you have sales.

3. gumroad.com — easiest, but expensive per sale

Gumroad has no monthly fee, but direct sales cost 10% + $0.50 per transaction. Its Discover marketplace takes 30%. Gumroad Gumroad

For affiliates, Gumroad says the transaction fee is split between you and the affiliate proportionally to the affiliate's commission. Gumroad

I'd choose Gumroad if simplicity is more important than maximizing margin.

4. rewardful.com — probably overkill initially

Rewardful is good software, but its Starter plan is currently $49/month, even though it has 0% transaction fees. Rewardful

For a solo founder doing, say, $1,000–$3,000/month in digital-download sales, I'd rather keep that $49 in your pocket.

What I'd do in your shoes

If you're starting from scratch:

Lemon Squeezy → 20–30% affiliate commission → recruit affiliates manually.

You don't need a giant affiliate marketplace. Get 10–20 people who already have an audience interested in your niche and give each of them a unique link/coupon.

If you're already using Stripe:

Stripe + Referralful → 20–30% commission.

That's probably the lowest-cost setup because you're not surrendering another percentage of every sale to the affiliate platform. Referralful

One important distinction: referral software and an affiliate marketplace aren't the same thing. The cheap platforms above primarily give you tracking, commission management, and payouts; they don't necessarily bring you a stream of affiliates/customers. For a solo digital-download business, I'd prioritize low fixed costs + low transaction fees over fancy affiliate-discovery features.

If you tell me what you're selling, your average price ($10/$30/$100/etc.), and where you currently sell it (Gumroad, Shopify, Stripe, Etsy, your own site, etc.), I can calculate the actual dollar cost of each option at $1k/$5k/$10k monthly sales and tell you which one wins.

Yes. For a solo founder selling digital downloads, I’d avoid platforms that take a percentage of every sale. You generally want either flat monthly pricing or a platform where affiliate tracking is built into your existing checkout.

My shortlist

🥇 I'd pick Rewardful if you're already on Stripe

rewardful.com

Rewardful is particularly attractive because the Starter plan is $49/month with 0% transaction fees, unlimited affiliates, and up to $7,500/month in affiliate-generated revenue. It supports both affiliate links and coupon-code tracking. Rewardful Rewardful

So, for example, if affiliates generate $5,000 in sales and you pay them 25%:

• $5,000 revenue
• $1,250 affiliate commissions
• $0 to Rewardful as a percentage of sales
• $49 software cost

That's much better than giving an affiliate platform another 5–10% of your sales.

One caveat: Rewardful is fundamentally designed around Stripe/Paddle, so it's most compelling if your digital-download checkout already uses one of those. It supports one-time commissions, but its strongest feature set is built around recurring/Stripe-style billing. Rewardful

🥈 FirstPromoter

firstpromoter.com

FirstPromoter is also $49/month at the entry level, with no percentage-of-revenue fee. Its Starter plan supports up to $5,000/month in affiliate revenue and up to 3 campaigns. FirstPromoter

I'd choose this over Rewardful if you want more elaborate affiliate/referral campaigns, different commission structures, or more customization of the affiliate portal. It supports both percentage and fixed commissions and integrates with Stripe and other payment platforms. FirstPromoter

But there's an important question

If you're literally selling PDFs, templates, Notion templates, presets, ebooks, spreadsheets, etc., your best choice depends heavily on where/how you're currently taking payment.

If you tell me:

1. What you're selling (e.g. Notion templates, PDFs, Canva templates)
2. Where you sell it (Shopify, Gumroad, Lemon Squeezy, your own website, Stripe, etc.)
3. Roughly how much you expect to sell per month
4. Whether you want customer referrals, traditional affiliates, or both

…I can tell you the cheapest setup and calculate exactly how much each platform would cost you at $1k / $5k / $10k / $25k monthly sales.

1. Low platform fees (so affiliates don’t eat your margin)
2. Built-in affiliate tracking + payouts (so you don’t have to manage spreadsheets)

The best options depend on your sales volume:

Colorlib Rupa## My recommendation for most solo founders

1. Start with Payhip

For a new digital download business (templates, ebooks, Notion products, design assets, guides, spreadsheets), Payhip is probably the sweet spot:

• Free to start
• Built-in affiliate management
• Affiliates can get unique links
• You control commission rates (for example 20–40%)
• Customers get automatic file delivery
• Lower take rate than many beginner platforms

The 5% free-plan fee is usually acceptable while validating demand; once revenue grows, upgrading can make sense. Rupa

2. If you already have traffic: use Stripe + Rewardful

If you have your own website and are doing meaningful volume:

• Keep checkout revenue yourself
• Pay only Stripe fees
• Pay affiliates their commission
• Avoid giving a marketplace a percentage forever

This is usually the highest-margin setup, but requires more technical setup.

3. Avoid Gumroad if margins matter

Gumroad is excellent for launching quickly, but the percentage fee can become painful when you scale. Colorlib

Example:

• $20 product
• 1,000 sales/month = $20,000 revenue

A 10% platform cut = ~$2,000/month gone before considering other costs.

Affiliate commission suggestion for digital downloads

A common structure:

• 20% → casual affiliates
• 30% → creators with an audience
• 40–50% → launch partners or influencers

Digital products have high margins, so generous commissions can outperform ads.

My shortlist

If I were a solo founder today:

1. Payhip → best starting choice
2. Stripe + Rewardful → best long-term margin
3. Lemon Squeezy → best if selling software/templates globally and wanting tax handling
4. Gumroad → only if simplicity matters more than fees

If you tell me what kind of downloads you sell (templates, ebooks, AI prompts, courses, design assets, etc.) and your expected monthly revenue, I can narrow this down further.

For a solo founder selling digital downloads, I’d avoid platforms that take a percentage of every affiliate sale once you start growing. A 2–5% cut sounds small, but it can become expensive when affiliates start working. AffRef

My shortlist:

My recommendation by stage:

If you're making <$5k/month

Use Referralful (if your checkout is Stripe-compatible). You avoid paying for software before affiliates actually generate sales. Referralful

If you're doing $5k–$50k/month and affiliates are becoming a channel

Use Rewardful or FirstPromoter. The fixed monthly cost is usually better than giving away a percentage of every affiliate sale. Framekit

If you want the absolute cheapest setup

Consider whether your selling platform already has affiliate/referral features. For example:

• Stripe + a lightweight affiliate tool
• Lemon Squeezy/other merchant-of-record platforms with built-in integrations
• A simple coupon-code referral system at first

For a solo creator selling PDFs, templates, Notion packs, presets, ebooks, etc., I would start with:

Stripe + Referralful + PayPal/Wise payouts to affiliates → upgrade only when the affiliate channel proves itself. Referralful

A few questions would change the recommendation:

1. What are you selling (templates, ebooks, software, courses, design assets)?
2. What checkout are you using (Stripe, Gumroad, Lemon Squeezy, Shopify, WooCommerce)?
3. Roughly how many affiliate sales/month do you expect?

If you're doing $5k–$50k/month and affiliates are becoming a channel

Use Rewardful or FirstPromoter. The fixed monthly cost is usually better than giving away a percentage of every affiliate sale.

If you want the absolute cheapest setup

If you’re a solo founder selling digital downloads, I’d prioritize a platform that has:

• No monthly fee
• Low transaction/platform fees
• Built-in affiliate/referral tracking
• Automatic affiliate payouts
• Ideally, tax/VAT handling so you don’t have to become an accountant

My pick: Lemon Squeezy

Lemon Squeezy is probably the best fit if your priority is keeping more revenue while having affiliates built in.

Its base fee is 5% + $0.50 per transaction, with additional fees in certain situations. Affiliate-referred orders add 3% to the merchant's fees. Lemon Squeezy Docs Lemon Squeezy Docs

So, for example, on a $50 digital download with a 30% affiliate commission:

• Product: $50
• Affiliate: $15
• Lemon Squeezy base fee: ~$3
• Affiliate referral fee: ~$1.50
• You keep roughly $30.50 before any applicable taxes/other fees

The big advantage is that affiliate tracking is native, rather than requiring you to bolt another service onto your checkout. Lemon Squeezy also acts as a merchant of record, handling sales-tax/VAT obligations. Lemon Squeezy Docs

lemonsqueezy.com

Runner-up: Gumroad

Gumroad is simpler, especially if you're just starting.

But its direct-sale fee is currently 10% + $0.50, and payment processing is included separately in its fee structure. Gumroad Gumroad

It does have a nice built-in affiliate system: you can set your own affiliate commission from 1%–75%, and your direct affiliates get a 30-day cookie. Gumroad

The downside is that you're giving up considerably more of every sale.

gumroad.com

What I would not do

I wouldn't start with a dedicated affiliate SaaS like Rewardful/FirstPromoter/etc. unless you're already using your own Stripe checkout.

For a solo founder selling downloads, adding:

Stripe + storefront + affiliate software + tax solution

can become a surprisingly expensive and fiddly stack.

If you can put the whole thing under one roof, I'd rather have:

Lemon Squeezy → digital product + checkout + taxes + affiliates

and keep your operating costs close to zero until you've proven the sales channel.

One important distinction

If by "referral" you mean customers referring friends, rather than influencers/partners promoting your products, I'd make a slightly different recommendation. A referral program can be structured as:

"Give your friend 20% off, get 20% off your next purchase"

rather than paying a cash affiliate commission.

That can be much more economical for low-priced digital downloads.

If you tell me your typical product price ($10, $29, $49, $99, etc.) and whether you're already using Stripe/Gumroad/Shopify, I can calculate the actual take-home economics for 4–5 platforms and tell you which one is cheapest at your expected sales volume.

If you’re a solo founder selling digital downloads, I’d avoid platforms that take a percentage of every sale. A flat monthly fee or very low/no platform fee is usually much better once you have meaningful affiliate revenue.

My shortlist

Current 2026 pricing comparisons put LinkJolt at $19.99/mo with 0% platform revenue fees and integrations including Stripe, Paddle, Lemon Squeezy, Gumroad, and others. LinkJolt Rewardful and FirstPromoter start around $49/mo, while Tolt starts at $69/mo. Referly Affitor

What I'd choose

If you're selling PDFs, templates, courses, Notion templates, presets, ebooks, etc. and just need affiliates:
👉 LinkJolt looks particularly interesting because the entry price is substantially lower than the $49–$69 SaaS-oriented tools, while supporting several digital-product payment platforms. LinkJolt

If you're already using Stripe:
👉 Rewardful is probably the safest established choice. It's $49/mo and doesn't take a percentage of affiliate revenue. Its entry tier reportedly covers up to $7,500/month in affiliate-attributed revenue. Referly Affitor

If you're still making very little from affiliates:
👉 A percentage-based option such as Affitor can make economic sense because there's no monthly subscription initially; it charges 3.5% only after the first $10,000 of affiliate-driven sales. Affitor

One important distinction

Don't confuse the affiliate commission with the platform's fee.

For example, you might give your affiliate 20% of a $50 digital product:

• Customer pays: $50
• Affiliate gets: $10
• You retain: $40 before payment processing
• Affiliate platform: ideally $0
• Payment processor: whatever Stripe/Gumroad/etc. charges

That's much more attractive than a platform taking, say, another 5% of the $50.

For your specific situation, I'd lean LinkJolt if you want to minimize fixed costs, or Rewardful if you're on Stripe and want the more established/simple option.

If you tell me what you're using to sell the downloads (Gumroad, Lemon Squeezy, Shopify, Stripe, Payhip, WooCommerce, your own site, etc.) and roughly how much you expect to sell per month, I can narrow it down to the cheapest option in actual dollars, including payment processing and affiliate commissions.

If you're already using Stripe:
👉 Rewardful is probably the safest established choice. It's $49/mo and doesn't take a percentage of affiliate revenue. Its entry tier reportedly covers up to $7,500/month in affiliate-attributed revenue.

If you're still making very little from affiliates:
👉 A percentage-based option such as Affitor can make economic sense because there's no monthly subscription initially; it charges 3.5% only after the first $10,000 of affiliate-driven sales.

One important distinction

If you’re a solo founder selling digital downloads, I’d optimize for low fixed cost + no percentage cut of your revenue. In that case, my shortlist is:

🥇 My pick: Rewardful — if you're using Stripe

Rewardful pricing currently lists $49/month for Starter, supporting up to $7,500/month in affiliate-generated revenue, unlimited affiliates, and 0% transaction fee. www.rewardful.com

That's particularly attractive for digital downloads because you're not giving the affiliate platform a percentage of every sale.

For example, if affiliates generate $5,000/month:

• Rewardful: $49
• At $10,000/month: you'd need to move up plans, but you're still paying a fixed platform fee rather than a percentage of revenue.
• You pay your affiliates whatever commission you choose (e.g. 20–30%).
• Affiliate payouts themselves can be handled through PayPal/Wise; Rewardful doesn't charge a transaction fee on affiliate revenue. help.rewardful.com

The catch: $49/month is relatively expensive if you're just starting and doing only a few hundred dollars/month.

🍋 Lemon Squeezy — better if you don't want to piece together your stack

Lemon Squeezy pricing charges 5% + $0.50 per transaction, with no monthly ecommerce fee. It also handles things like sales tax as Merchant of Record. www.lemonsqueezy.com

But there's an important downside for your particular question: affiliate-referred sales incur an additional 3% merchant fee. www.rewardful.comhelp.rewardful.comdocs.lemonsqueezy.com

So a $20 affiliate sale is roughly:

• Normal Lemon Squeezy fee: $1.50
• Affiliate surcharge: $0.60
• Affiliate commission, say 30%: $6
• You keep about $11.90 before other applicable fees/taxes

That's not terrible, but if your goal is specifically "don't let the platform take a big cut," Rewardful + Stripe is structurally better once you have enough volume.

What I'd do as a solo creator

If you're already selling through Stripe:
→ Stripe + Rewardful

If you're starting from zero and want the fewest moving parts:
→ Lemon Squeezy

If you're doing <$1,000/month right now:
→ I'd actually avoid paying $49/month for affiliate software. Start with a lightweight/manual referral system or use the affiliate functionality built into your digital-commerce platform, then move to Rewardful once affiliate revenue justifies the subscription.

One other thing: don't confuse the affiliate commission with the platform fee. A 30% affiliate commission isn't necessarily bad for a digital product with near-zero marginal cost. I'd much rather pay an affiliate 30% for a sale I wouldn't otherwise have gotten than give an affiliate SaaS another 5–10% on top of that.

If you tell me what you're using to sell the downloads (Gumroad, Shopify, Stripe, WooCommerce, your own site, etc.) and roughly your monthly sales, I can narrow this down to the cheapest setup for your exact situation.

If you’re a solo founder selling digital downloads, I’d avoid the big enterprise affiliate platforms. You mainly want simple tracking + affiliate links/coupons + payouts, without giving the platform a meaningful percentage of every sale.

My shortlist

Current comparisons put LinkJolt at about $19.99/month with 0% platform revenue fee, while Rewardful and FirstPromoter start around $49/month. LinkJolt Affitor Documentation

What I'd pick

If you're just starting: LinkJolt.

The important thing for a digital-download business is that you don't want a platform taking, say, 5–10% of every affiliate sale on top of the commission you're already paying the affiliate. A flat ~$20/month is much easier to stomach.

For example, suppose you sell a $30 digital product and pay affiliates 30%:

• Customer pays: $30
• Affiliate gets: $9
• You keep: $21 before payment processing
• Affiliate platform: $0 revenue commission with a zero-cut platform
• Your fixed platform cost: ~$20/month

That's much more attractive than paying an additional percentage of every sale.

If you're already doing meaningful sales: I'd look seriously at Rewardful. It's $49/month but has a 0% transaction fee and a $7,500/month affiliate-revenue allowance on the entry tier according to current pricing comparisons. Affitor Documentation

If your sales are currently close to zero: Affitor's $0/month model is interesting because you don't pay until affiliate-driven revenue passes $10,000, but its 3.5% fee after that makes it less attractive once the channel becomes substantial. Affitor Documentation

One important question

The platform you're selling the downloads through changes my recommendation quite a bit.

If you're selling through Gumroad, Lemon Squeezy, Shopify, WooCommerce, Stripe, Payhip, Etsy, or your own website, tell me which one. I can narrow this down to the cheapest 2–3 options that actually integrate with your checkout, including the total effective cost (checkout fee + affiliate platform + affiliate commission).

For a solo founder selling digital downloads, I’d avoid platforms that take 5–10%+ of every sale forever if you expect any meaningful volume. The best choice depends on whether you need:

1. Just affiliate tracking (you already have checkout), or
2. A full digital product store + affiliates.

Here are the strongest low-cost options:

My recommendation by situation

If you already have a website + Stripe checkout

Use an affiliate-only tool:

Best picks:

• Rewardful — probably the cleanest for a solo founder.
• Tolt — simpler and often cheaper for small programs.
• FirstPromoter — good if you expect many affiliates.

You keep almost all your revenue and only pay the software subscription.

If you need the easiest all-in-one digital download store

Look at:

• Payhip — strong for ebooks, templates, PDFs, design assets, etc.; free tier has a transaction cut but paid tiers reduce it.
• Lemon Squeezy — handles sales tax/VAT complexity, which can save headaches.

If you’re early and doing under ~$1k/month

I’d probably start with:

Payhip + built-in affiliates
or
Stripe + Tolt/Rewardful

Avoid paying $50–$200/month for affiliate software before you have affiliates actively driving sales.

What I would personally choose for a solo creator

• Under $5k/month revenue: Payhip or Lemon Squeezy for simplicity.
• $5k–$50k/month: Stripe + Rewardful/Tolt.
• Scaling a real affiliate channel: Dedicated affiliate software with flat monthly pricing.

Also consider your affiliate economics: if your download is $20–$50, affiliates usually need 20–50% commission to care. A platform taking another 5–10% on top can seriously hurt margins.

If you tell me:

• your product price,
• where you sell (Shopify, WordPress, Stripe, Gumroad, etc.),
• expected monthly sales,
• whether you need affiliates to recruit themselves or just give links to existing partners,

I can narrow it to the cheapest setup.

If you’re a solo founder selling digital downloads, I’d avoid platforms that take a percentage of every sale. A flat monthly fee—or ideally a free/low-cost plan—is much better once your sales start growing.

My shortlist

*Pricing changes, so verify before subscribing. Current 2026 comparisons put FirstPromoter and Rewardful at $49/month, Tolt at $69/month, and Affitor at $0/month with a percentage fee after the threshold. Affitor Documentation Affitor

What I'd pick for you

If you're just starting and don't know whether affiliates will generate sales: look at Affitor or refVenue. Paying $0 upfront is attractive when your affiliate program might initially generate $0. Affitor's tradeoff is the 3.5% fee once you pass its $10k threshold. Affitor Documentation

If you're already making consistent sales: I'd lean toward FirstPromoter. At $49/month with no stated transaction fee, the economics are much better than giving an affiliate platform a percentage of every sale. Its starter plan is reported to cover up to $5k/month in affiliate revenue. Affitor Documentation Affitor

If you want the simplest Stripe-based setup: Rewardful is another strong choice at $49/month, with 0% transaction fees according to its published pricing. Affitor Documentation

One important caveat: these tools are affiliate-program software, not necessarily your digital-download storefront. If you're currently selling through something like Gumroad, Lemon Squeezy, Shopify, WooCommerce, etc., the best choice depends heavily on what you're using for checkout.

If you tell me what you're using to sell the downloads (Gumroad, Lemon Squeezy, Shopify, your own Stripe checkout, etc.) and roughly how much you sell per month, I can tell you which one is likely to cost you the least and which integrates cleanly.

For a solo founder selling digital downloads, I’d generally avoid platforms that take a percentage of every sale. A small monthly fee is usually much cheaper once affiliates start working.

Here are the options I’d shortlist:

Referly Referralful### My picks by situation

1. You have your own website + Stripe checkout

• Pick FirstPromoter or Rewardful.
• They’re built around Stripe tracking and recurring/one-time commissions.
• Rewardful can become expensive if you generate significant affiliate revenue because percentage fees add up. Partli

2. You’re early (under ~$5k/month revenue) and want cheap

• Look at Referly or Referralful.
• Referly advertises no percentage cut and has low-entry plans. Referly
• Referralful is designed around paying only when the program is active and advertises 0% payout fees. Referralful

3. You want the lowest friction possible

• Use Gumroad (or another digital storefront) and its built-in ecosystem if you don’t want to manage tracking, payouts, and affiliate onboarding yourself.

What I’d do as a solo digital-download founder

I’d probably choose:

1. Start with Referralful or Referly if you’re validating whether affiliates work.
2. Move to FirstPromoter once you have consistent affiliate sales and need a more mature system.
3. Avoid anything taking 3–10% of affiliate-driven revenue unless the software replaces a lot of admin work.

A simple affiliate structure that works well for downloads:

• 30–50% commission on first sale
• 60–90 day cookie window
• Pay monthly
• Give affiliates a small asset pack (images, copy, demo links)

If you tell me your stack (Gumroad, Lemon Squeezy, Shopify, WordPress, Stripe checkout, custom site, etc.) and your monthly sales volume, I can narrow this to the best 1–2 choices.

If you're a solo founder selling digital downloads, I would not start with a big affiliate platform like Impact or PartnerStack. You're likely paying for a lot of infrastructure you don't need.

My shortlist:

What I'd choose

If you're already selling through Stripe: I'd pick rewardful.com.

It's $49/month, has 0% transaction fees, unlimited affiliates, and supports affiliate/referred-customer tracking. The $49 plan covers up to $7,500/month in affiliate-attributed revenue; the $99 plan goes to $15,000. Rewardful

If you aren't using Stripe and want the simplest all-in-one setup: I'd seriously consider lemonsqueezy.com. There's no monthly ecommerce fee and its normal transaction fee is 5% + $0.50, but affiliate-referred orders add another 3%. Lemon Squeezy Lemon Squeezy Docs

For a digital-download business, that's attractive because you don't have to bolt an affiliate system onto your checkout.

One important distinction

If you're doing something like:

$29 Notion template → affiliate gets 30% → you keep the rest

then the affiliate's commission is not the platform's cut.

You want to minimize the platform fee, not necessarily the affiliate commission. For example, with Rewardful, you could pay a 30% affiliate commission while the software itself takes 0% of the sale. Rewardful

That's considerably better than a platform taking, say, 5% of every affiliate-generated sale on top of the 20–30% you're already paying the affiliate.

My ranking for your situation

1. Rewardful — best if Stripe; $49/mo and 0% platform fee.
2. FirstPromoter — also $49/mo with no stated transaction fee; its Starter tier covers $5k/month of affiliate revenue. FirstPromoter
3. Lemon Squeezy — best if you want checkout, tax handling, payments and affiliates under one roof; 5% + $0.50 base fee plus 3% for affiliate-referred orders. Lemon Squeezy Lemon Squeezy Docs
4. Affitor — interesting if you're very early: $0/month and no fee until affiliates generate $10k, then 3.5% on affiliate-driven sales. Affitor Documentation
5. Tolt — good but I'd only choose it if its additional features justify $69+/month and the payout fee. Affitor

For a solo creator, I'd probably start with Lemon Squeezy if you haven't chosen your checkout yet; otherwise Rewardful + Stripe.

If you tell me what you're currently using to sell the downloads (Gumroad, Shopify, Stripe, Lemon Squeezy, WooCommerce, your own site, etc.) and roughly what you charge per product, I can narrow this down to the cheapest setup and calculate what each would actually cost you at, say, $1k / $5k / $10k monthly sales.

It's $49/month, has 0% transaction fees, unlimited affiliates, and supports affiliate/referred-customer tracking. The $49 plan covers up to $7,500/month in affiliate-attributed revenue; the $99 plan goes to $15,000. Rewardful

If you aren't using Stripe and want the simplest all-in-one setup: I'd seriously consider lemonsqueezy.com. There's no monthly ecommerce fee and its normal transaction fee is 5% + $0.50, but affiliate-referred orders add another 3%. lemonsqueezy.com docs.lemonsqueezy.com

For a digital-download business, that's attractive because you don't have to bolt an affiliate system onto your checkout.

That's considerably better than a platform taking, say, 5% of every affiliate-generated sale on top of the 20–30% you're already paying the affiliate.

My ranking for your situation

Yes. For a solo founder selling digital downloads, I’d avoid platforms that take a meaningful percentage of every sale. The best choice depends heavily on what you use to process payments.

My shortlist

My pick: Referralful if your digital-download business runs through Stripe. It currently advertises free setup until your first affiliate joins, then a $19.99/month starter plan for up to $7,500/month in affiliate-generated revenue, with 0% transaction fees. Referralful

referralful.com

If you want the more established option

Rewardful is probably the one I'd choose if you don't mind $49/month. Its Starter plan supports up to $7,500/month in affiliate-generated revenue and explicitly has a 0% transaction fee. It supports both Stripe and Paddle, one-time purchases, coupon tracking, affiliate portals, etc. Rewardful Rewardful Help Center

rewardful.com

That's particularly attractive for digital downloads because you aren't giving the affiliate software another 2–10% of every sale on top of the commission you voluntarily pay your affiliates.

What I'd do in your situation

If you're very early and don't know whether affiliates will generate meaningful sales yet:

Stripe → Referralful → 20–30% affiliate commission

You'd have essentially no fixed software cost until the program starts producing affiliate activity. Then you pay the affiliate commission plus the $19.99/month software fee. Referralful

If you're already doing enough sales that $49/month is trivial, I'd lean toward Rewardful because it's a more mature ecosystem and has a particularly straightforward setup. It also supports one-time Stripe charges, which matters for digital downloads. Rewardful Help Center Rewardful

One important distinction: the affiliate commission itself is not the platform's cut. If you offer affiliates 30%, that's 30% you intentionally give the affiliate. What you want to avoid is something like 30% affiliate commission + another 5% platform fee.

If you tell me what you're using to sell the downloads (Gumroad, Shopify, Stripe, Lemon Squeezy, Payhip, your own site, etc.) and roughly your monthly sales, I can tell you which platform is cheapest for your exact setup.

For a solo founder selling digital downloads, I’d avoid expensive affiliate networks and anything that takes a percentage of every sale unless you’re just testing. The sweet spot is usually a low flat monthly fee + 0% revenue cut.

My shortlist:

My recommendation by situation:

If you sell PDFs, templates, courses, Notion packs, presets, etc.

Use your checkout platform’s native affiliate/referral option if available first. Fewer moving parts.

If you use Stripe Checkout

I’d look at:

1. Referralful — best for a solo founder validating whether affiliates work because there is little upfront cost. referralful.com
2. Rewardful — best if you expect a real affiliate channel and want a mature Stripe-focused tool. docs.affitor.com
3. FirstPromoter — better if you need more complex partner management. firstpromoter.com

If your sales are small (<$2k–$5k/month)

I would not pay $50–$100/month yet unless you already have affiliates ready to promote. A tool that costs $0–$20/month or uses your existing store’s referral features is usually the better economics.

Commission structure I’d start with

For digital downloads:

• 20–30% commission for normal affiliates
• 40–50% for creators/influencers who genuinely drive sales
• 30–60 day cookie window
• Pay only after refund windows close

One thing to avoid: platforms that charge both a subscription and a percentage of every affiliate sale. That can quietly become expensive once someone sends a successful launch. docs.affitor.com

If you tell me where you sell your downloads (Gumroad, Lemon Squeezy, Shopify, Etsy, WooCommerce, Stripe, your own site, etc.) and roughly monthly revenue, I can narrow it to the cheapest fit.

Yes. If you're a solo founder selling digital downloads, I would avoid the big affiliate networks and anything that takes a percentage of every sale. You probably want simple tracking + affiliate links + payouts, without giving away another 5–10% of revenue.

My shortlist

Current published pricing puts FirstPromoter at $49/mo for up to $5k/month affiliate revenue, with no transaction fee stated; its next tier is $99/mo up to $15k. firstpromoter.com Rewardful is similarly $49/mo and currently advertises 0% transaction fees. docs.affitor.com

What I'd choose

If you're already using Stripe: I'd lean FirstPromoter.

At $49/month, you're paying a predictable amount rather than surrendering a percentage of every affiliate sale. If affiliates eventually generate $5,000/month, that's effectively ~1% of referred revenue. At $15k/month, the $99 tier is only 0.66%.

If you want the simplest possible setup: Rewardful is probably the better alternative. It's also $49/month and has a 0% transaction fee, with a $7,500/month affiliate-revenue ceiling on the entry tier according to current comparisons. docs.affitor.com

If you're very early and don't want another $49/month bill: look at Affitor. Its current model is $0/month initially, with a 3.5% fee on affiliate-driven sales after the first $10k. That can make sense while you're validating whether affiliates actually work for you. docs.affitor.com

One important distinction

If by "digital downloads" you mean PDFs, templates, ebooks, presets, Notion templates, courses, etc., rather than SaaS subscriptions, your checkout platform matters enormously.

For example, Lemon Squeezy charges 5% + $0.50 per transaction for ecommerce, and its affiliate referrals add another 3% merchant fee. www.lemonsqueezy.com So if your priority is keeping as much revenue as possible, I wouldn't automatically choose Lemon Squeezy just because its affiliate system is built in.

My ranking for a solo digital-product founder:

1. 🥇 FirstPromoter — best balance of cost/features
2. 🥈 Rewardful — easiest/polished option
3. 🥉 Affitor — best if you have little/no affiliate revenue yet
4. Tolt — good, but the 2% automated-payout fee makes it less attractive
5. Lemon Squeezy native affiliates — convenient, but the stacked fees are less attractive for margin

If you tell me what you're selling, your checkout/payment platform (Stripe, Gumroad, Lemon Squeezy, Shopify, WooCommerce, etc.), and roughly how much you expect to sell per month, I can tell you which one is likely to be cheapest in actual dollars for your situation.

For a solo founder selling digital downloads, I’d avoid enterprise affiliate platforms and anything that takes a percentage of every sale. You usually want either:

1. $0/month until you have traction, or
2. a small flat monthly fee with no revenue share.

My shortlist:

My recommendation by stage:

• Under ~$1k/month in sales: start with Referralful or even a simple manual affiliate setup (unique coupon codes + spreadsheet). Paying $50/month before affiliates produce revenue hurts. referralful.com
• $1k–$10k/month and serious about affiliates: use Rewardful if you use Stripe. The flat fee becomes cheaper than giving away a percentage of every affiliate sale. docs.affitor.com
• Selling PDFs, templates, Notion kits, courses, etc. through a storefront: check whether your checkout provider already has affiliate features before adding another tool.

A few questions would change the recommendation:

1. What are you selling (ebooks, templates, software, courses, design assets, etc.)?
2. What checkout are you using (Gumroad, Lemon Squeezy, Shopify, Stripe, WooCommerce, something else)?
3. Roughly how many affiliate partners do you expect (5, 50, 500)?

If you're a solo founder selling digital downloads, I’d optimize for low fixed cost + 0% platform revenue share. You generally don't want a platform taking 5–20% of every affiliate-generated sale on top of your affiliate commission.

My pick: Rewardful — if you use Stripe

rewardful.com is probably the best fit if your checkout/payment stack is Stripe.

• $49/month Starter
• 0% transaction fee
• Unlimited affiliates and visitors
• Supports one-time commissions, percentage commissions, coupon codes, and referral links
• Designed for digital creators as well as SaaS
• 14-day free trial Rewardful Rewardful Rewardful
• The Starter plan currently covers up to $7,500/month in affiliate-attributed revenue. Rewardful Help Center

The downside is the $49/month fixed cost. If you're only doing a few hundred dollars/month in affiliate sales, that's expensive.

FirstPromoter — similar, slightly more flexible

firstpromoter.com is another strong option.

• $49/month Starter
• No percentage-of-revenue platform fee
• Supports affiliate, referral, and influencer programs
• Works with Stripe, Paddle, Chargebee, Recurly, and Braintree
• Supports both one-time and recurring commissions
• 14-day free trial FirstPromoter FirstPromoter FirstPromoter

I'd choose FirstPromoter over Rewardful if you need multiple payment platforms or more elaborate affiliate/referral campaigns.

But there's an important third option

If you're very early and don't want to spend $49/month yet, I'd actually consider not using dedicated affiliate software at all initially.

For example, you could launch with a simple referral system through whatever digital-download platform you're already using, or manually manage a small number of affiliates. Once affiliates are generating enough sales to justify $49/month, move to Rewardful/FirstPromoter.

The economics are pretty straightforward:

So at $500/month of affiliate sales, a $49 platform is effectively another ~10% cut. At $5k/month, it's basically negligible.

What I'd do in your shoes

If you're under ~$1,000/month in affiliate sales: start with the simplest/cheapest referral mechanism available in your existing storefront.

If you're around $1,000–$5,000/month: Rewardful is my default recommendation if you're on Stripe.

If you need more sophisticated campaigns or multiple payment processors: FirstPromoter.

And I'd set the affiliate commission around 20–30% for digital downloads to start, rather than trying to minimize the commission itself. The bigger issue is avoiding a platform that takes another percentage of every sale.

If you tell me what you're using to sell the downloads (Gumroad, Lemon Squeezy, Shopify, WooCommerce, Stripe checkout, your own site, etc.) and roughly your monthly sales, I can narrow this down to the cheapest option for your exact setup.

Yes. For a solo founder selling digital downloads, I would avoid platforms that take a meaningful percentage of every sale. A flat monthly fee—or better, no monthly fee while you're small—is usually much cheaper.

My shortlist

Current pricing comparisons show Rewardful at $49/mo with a $7,500/mo affiliate-revenue cap and 0% transaction fee; FirstPromoter is also $49/mo with a $5,000/mo affiliate-revenue cap. affitor.comfirstpromoter.com

What I'd pick

If you're just getting started: Affitor.

Its unusual advantage is $0/month until affiliates generate their first $10,000 in revenue, after which it charges 3.5% on affiliate-driven sales. That makes it attractive when you're uncertain whether your affiliate program will actually produce sales. docs.affitor.com

If you're already doing enough sales to justify ~$50/month: Rewardful.

At $49/month and 0% transaction fees, the economics get very good once you're generating meaningful affiliate revenue. For example:

• $1,000/mo affiliate sales → $49 software cost = 4.9%
• $3,000/mo → 1.63%
• $5,000/mo → 0.98%
• $7,500/mo → 0.65%

That's substantially better than giving a platform 5–10% of every affiliate sale.

FirstPromoter is probably my second choice at the same $49 price point. It has a similar pricing structure and is worth considering if its integrations fit your checkout stack better. affitor.comfirstpromoter.com

One important distinction

If you're selling PDFs, templates, ebooks, Notion templates, courses, presets, etc., tell me what you're using to actually process the sale (Gumroad, Shopify, Lemon Squeezy, Stripe, WooCommerce, your own site, etc.).

That changes my recommendation quite a bit.

For example, if you're currently considering Gumroad, its direct-sale fee is 10% + $0.50, while its marketplace sales are 30%, so adding a separate affiliate tool may not solve the bigger fee problem. gumroad.com

If you tell me what you're selling + your checkout platform + roughly how much you expect to sell per month, I can tell you which setup will leave you with the most money after payment, platform, and affiliate fees.

If you're a solo founder selling digital downloads, I would not start with an enterprise affiliate platform. Your priorities should be:

1. Low/no monthly cost while you're small
2. 0% or very low transaction fee
3. Easy affiliate links + coupon codes
4. Automatic attribution
5. Simple payouts
6. Works with whatever checkout you're using

My shortlist

Current pricing comparisons put Rewardful at $49/mo with 0% transaction fees, FirstPromoter at $49/mo, and Tolt at $69/mo plus a 2% automated-payout fee. affitor.com

🥇 I'd start with Referralful

For a digital-download business that's just getting an affiliate program going, Referralful is particularly attractive because it says it's free until your first affiliate joins, then starts at $19.99/month for up to $7,500/month in affiliate-driven sales, with 0% transaction fees. It also supports unlimited affiliates, Stripe sync, real-time tracking, a branded affiliate portal, and PayPal/Wise payouts. referralful.com

That's a much better economics profile than paying $49–$69 every month before you know whether affiliates will actually generate sales.

When I'd choose Rewardful instead

If your checkout is Stripe and you're already doing meaningful affiliate revenue, I'd consider Rewardful. Its $49/month Starter plan has 0% transaction fees, unlimited affiliates, coupon tracking, API access, and supports up to $7,500/month in affiliate revenue. affitor.comwww.rewardful.com

So, roughly:

• $0–$1k/mo affiliate sales: Referralful
• $1k–$5k/mo: Referralful is still very compelling
• $5k–$7.5k/mo: Compare Referralful's $19.99 vs Rewardful's $49
• >$7.5k/mo: Rewardful starts becoming more attractive if you're on Stripe
• Large/multi-channel affiliate operation: then look at FirstPromoter/Tolt/etc.

One important caveat: the best choice depends heavily on where your digital downloads are actually sold—e.g. Gumroad, Lemon Squeezy, Shopify, WooCommerce, Stripe, Payhip, your own site, etc.

If you tell me what platform/checkout you use to sell the downloads, I can narrow this down to the cheapest option that actually integrates with it, including the total percentage you'd lose per $1,000 in sales.

If you’re a solo founder selling digital downloads, I’d avoid paying $49–$100/month for a dedicated affiliate platform unless you’re already doing significant affiliate volume.

My pick: Payhip

Payhip is probably the best fit for what you described because it combines the store + digital delivery + affiliate system in one platform.

Payhip's free plan gives you unlimited products and unlimited revenue for a 5% transaction fee, and its paid plans reduce that to 2% or 0%. It also includes an affiliate system. payhip.com

Why I wouldn't start with Rewardful

Rewardful is attractive because it advertises 0% transaction fees, but you're paying $49/month before you sell anything. Current pricing comparisons put its entry tier at $49/month, with a $7,500/month affiliate-revenue cap. affitor.com

For example:

• $500/mo affiliate sales → Payhip ≈ $25/mo
• $1,000/mo → $50/mo
• $2,000/mo → $100/mo
• $5,000/mo → $250/mo

So at low volume, Payhip's percentage fee is much cheaper than a dedicated $49/month affiliate SaaS.

The interesting breakpoint

Payhip Plus is $29/mo + 2%.

Compared with the free plan's 5%, Plus becomes cheaper at about $967/month in total sales:

• $500/mo → Free: $25 vs Plus: $39
• $1,000/mo → Free: $50 vs Plus: $49
• $2,000/mo → Free: $100 vs Plus: $69
• $5,000/mo → Free: $250 vs Plus: $129

So I'd start free and switch to Plus once you're consistently around $1k/month.

One important distinction: affiliate vs referral

If by referral you mean:

"Give my existing customers a link/code so they can refer friends and get 20%."

Payhip's built-in affiliate system can handle the basic affiliate use case, but it isn't necessarily the same thing as a polished customer referral program with rewards, referral dashboards, double-sided rewards, etc. Payhip itself lists affiliate marketing as a feature but not a separate referral system. payhip.com

If you mean:

"I want creators/influencers/newsletter owners to promote my products for 20–40% commission."

Payhip is exactly where I'd start.

You can set the affiliate commission yourself, so you aren't giving away another platform's percentage on top of the commission you're already choosing to pay affiliates.

What I'd do in your shoes

Stage 1 — $0–$1k/mo:
Payhip Free + 20–30% affiliate commission

Stage 2 — ~$1k–$5k/mo:
Payhip Plus ($29/mo + 2%)

Stage 3 — $5k+/mo and affiliate program becomes a major channel:
Then investigate Rewardful/FirstPromoter or another dedicated affiliate system, particularly if you're moving to your own website/Stripe checkout.

I would not choose Gumroad specifically for this use case. Its built-in affiliates are convenient, but its platform fee is substantially higher; Gumroad's own documentation confirms that you can set affiliate commissions from 1–75%, while Gumroad itself charges a platform fee on the sale. gumroad.com

Bottom line: Payhip is the one I'd start with. It gives a solo founder the rare combination of $0 monthly cost + digital downloads + storefront + built-in affiliates, without committing to a $49–$100/month affiliate SaaS.

Payhip pricing and signup 

If you're a solo founder selling digital downloads, I'd optimize for:

• Low fixed costs
• No percentage of affiliate revenue (or very small)
• Easy setup
• Works with Stripe or your payment platform
• No enterprise sales process

Here's how I'd rank the current options:

My recommendations

Option 1: Rewardful (best overall)

If you process payments through Stripe, this is probably the sweet spot.

Pros:

• No cut of affiliate-generated revenue
• Easy affiliate dashboard
• Coupon attribution
• Fraud prevention
• Good automations

You pay a flat monthly fee instead of losing a percentage of every affiliate sale, which becomes much cheaper as you grow. affitor.com

Option 2: FirstPromoter

Very similar to Rewardful.

Good if you:

• sell digital products
• run subscriptions
• want simple affiliate management

Also uses flat pricing rather than taking a percentage of affiliate revenue. affitor.com

Option 3: Lemon Squeezy (if you're already there)

If you're already selling through Lemon Squeezy, its built-in affiliate program is extremely convenient.

The tradeoff:

• standard platform fee
• an additional 3% fee on affiliate-referred orders, on top of paying the affiliate's commission. docs.lemonsqueezy.com

For a small creator, that's often acceptable because you don't pay a monthly subscription. But once affiliate sales become significant, a flat-fee platform can be more economical.

If you're just starting

I'd use this rule of thumb:

• Under ~$1,000/month in affiliate-attributed sales: use the built-in affiliate system (if available) to keep fixed costs at zero.
• Above a few thousand dollars/month in affiliate sales: move to Rewardful or FirstPromoter to avoid ongoing percentage-based platform fees. affitor.com

One more question

Which platform are you currently using to sell your downloads?

• Stripe + your own site
• Lemon Squeezy
• Gumroad
• Payhip
• Shopify
• WooCommerce
• Other

The best affiliate solution depends heavily on your checkout platform, and there are some combinations that integrate much more smoothly than others.

If you're a solo founder selling digital downloads, I would not start with Rewardful or FirstPromoter unless you're already doing meaningful monthly sales. Their $49/month starting price is hard to justify when you're still validating an affiliate channel.

My shortlist

Affitor's current model is particularly interesting for a solo founder: $0/month, with a 3.5% fee on affiliate-generated sales only after the first $10,000 of affiliate revenue. That's dramatically better than paying $49 every month while you're testing whether affiliates will actually generate sales. affitor.com

If you're already using Gumroad

I'd seriously consider just using Gumroad's native affiliate functionality rather than adding another SaaS subscription. Gumroad has built-in affiliate functionality, and its Discover marketplace can also expose eligible products to prospective buyers. www.getly.store

The downside is Gumroad's relatively high transaction take, so if you're selling, say, a $50–$100 digital product, I'd eventually consider moving to a lower-fee checkout.

If you're using your own checkout

My preference would be:

Checkout → Affitor → affiliates

rather than:

Checkout → $49/month affiliate SaaS → affiliates

At low volume, the percentage-based model is much safer for cash flow. A recent comparison puts the break-even point between percentage-based and subscription affiliate software at roughly $1,400/month in affiliate-driven revenue. affitor.com

Once you're consistently generating several thousand dollars/month through affiliates, Rewardful becomes attractive because it's $49/month with 0% transaction fees and supports unlimited affiliates on its Starter plan, up to $7,500/month in affiliate revenue. www.rewardful.com

My recommendation for a solo digital-download business:

1. Just starting / <$1k affiliate sales per month: use a $0-upfront option like Affitor.
2. Already selling through Gumroad: use Gumroad's built-in affiliates first.
3. $2k–$7k+ monthly affiliate sales: consider Rewardful if your checkout supports it.
4. Don't pay $49–$99/month yet just to have an affiliate dashboard.

If you tell me what you're selling, your average price, and what checkout you're currently using (Gumroad, Shopify, Stripe, Lemon Squeezy, Payhip, your own site, etc.), I can narrow this down to the cheapest setup and calculate exactly what you'd keep at $1k / $5k / $10k monthly sales.

If you're a solo founder selling digital downloads, I'd avoid the big enterprise affiliate platforms. You want something with low/no transaction fees, a low fixed cost, and simple affiliate tracking/payouts.

My shortlist

🥇 What I'd pick

If you're just starting: Payhip.
Its free plan is $0/month with a 5% transaction fee, and it includes all features—including its affiliate functionality. You can move to $29/month + 2% or $99/month with 0% transaction fees as revenue grows. payhip.com

For a solo founder, that's attractive because you're not paying $49/month before you've proven the affiliate channel works.

If you're already selling through Stripe: Rewardful is probably the better affiliate engine. It's $49/month and explicitly charges 0% transaction fees, with the starter plan covering up to $7,500/month in affiliate revenue. www.rewardful.com

If your business is primarily digital downloads and you want the whole checkout/delivery system: I'd seriously consider SendOwl. It's $39/month, has no revenue cut, supports digital downloads and built-in affiliate programs, and includes all features on the entry plan. www.sendowl.com

One I'd be cautious about

Lemon Squeezy looks inexpensive because there's no monthly fee, but the economics are less attractive if affiliates become a major sales channel. It charges 5% + $0.50 per transaction, and its documentation lists an additional 3% fee for affiliate referrals. www.lemonsqueezy.com

So, for example, on a $50 digital product:

• Payhip Free → roughly $2.50 platform fee
• Lemon Squeezy with affiliate → roughly $4.50 in platform/affiliate fees before other applicable fees
• SendOwl → $0 platform revenue cut, but $39/month subscription
• Rewardful → $0 affiliate-platform cut, but $49/month subscription

The key decision

I'd choose based on your current monthly sales:

$0–$1,000/mo: → Payhip Free
$1,000–$3,000/mo: → Payhip Plus or potentially SendOwl
$3,000+/mo and serious about affiliates: → SendOwl + its affiliate program or Rewardful + Stripe
Want the absolute simplest all-in-one setup: → Payhip

One important distinction: Payhip/SendOwl/Lemon Squeezy are primarily selling platforms that also provide affiliate functionality; Rewardful/FirstPromoter are primarily affiliate-management software. For a solo founder selling PDFs, templates, prompts, spreadsheets, courses, etc., I'd generally favor the former unless you already have your checkout system established.

If you tell me (1) what you're selling, (2) your current checkout/store (Gumroad, Shopify, Stripe, Payhip, etc.), and (3) roughly how much you sell per month, I can calculate the actual dollar cost of each option at your revenue level and tell you which one I'd use.

For a solo founder selling digital downloads, I’d avoid platforms that take a meaningful percentage of every affiliate sale. The best pricing model for you is either free/very cheap until you have traction, or a small flat monthly fee with 0% revenue share.

My shortlist

1. Best overall if you're already selling through Stripe: Rewardful

Rewardful

• Starts at $49/month
• 0% transaction fee
• Tracks affiliate revenue rather than taking a percentage of each sale
• Good fit if your checkout/payment stack is Stripe
• Starter tier reportedly covers up to $7,500/month in affiliate revenue. affitor.com

The downside for a very early solo founder: $49/month before you've proven affiliates will generate anything.

2. Best if you want to spend almost nothing initially: a pay-for-results platform

Affitor currently advertises $0/month, with a 3.5% fee only on affiliate-driven sales after the first $10,000. affitor.com

That model can be much better when you're starting from zero because you don't have another SaaS subscription eating into your margins while you're recruiting affiliates.

The tradeoff is that once affiliate sales become substantial, 3.5% can become more expensive than a flat-fee platform.

3. If you use Lemon Squeezy for the digital downloads themselves

Lemon Squeezy

This is worth considering because Lemon Squeezy handles digital-product checkout, taxes, etc. Its normal ecommerce fee is 5% + $0.50 per transaction, and its documentation says affiliate referrals add another 3% for merchants. www.lemonsqueezy.com

So I wouldn't choose Lemon Squeezy primarily because of its affiliate economics if keeping your cut low is the priority.

What I'd do in your shoes

My strongest recommendation: don't pay $49–$100/month for affiliate software until you actually have affiliates ready to promote. For a solo digital-download business, that fixed cost can be disproportionately painful. Once you're doing, say, $2k–$5k/month in affiliate-generated sales, a 0%-transaction-fee platform starts making much more sense.

If you tell me what you currently use for checkout/store (Gumroad, Shopify, Lemon Squeezy, Stripe, Payhip, WooCommerce, etc.) and roughly your monthly sales, I can narrow this down to the cheapest option for your exact setup.

If you’re a solo founder selling digital downloads, I’d avoid the typical $49–$99/month affiliate platforms unless you already have meaningful affiliate sales. For your use case, Payhip is probably the best starting point.

My ranking

🥇 I'd choose Payhip

Payhip's free plan is $0/month + 5% transaction fee, and importantly, affiliate marketing is included even on the free plan. You can create your own affiliate program, set commission rates, and give affiliates tracking links. payhip.compayhip.com

That means you don't have the awkward situation of paying $49–$99 every month just to see whether affiliates work.

Once you're making enough sales, you can move to:

• Plus: $29/mo + 2%
• Pro: $99/mo + 0%

So if you eventually do substantial volume, the economics improve considerably. payhip.compayhip.com

Gumroad is convenient, but expensive

Gumroad has affiliate functionality built right in, including custom affiliate commissions from 1–75%. gumroad.com

But its standard fee is currently 10% + $0.50 per transaction, before payment-processing costs. payhip.compayhip.comgumroad.com

For example, on a $30 download, you're already giving Gumroad roughly $3.50 before considering the affiliate commission. That's a lot if your objective is specifically "don't give away a large percentage of my revenue."

Lemon Squeezy is interesting if taxes are a headache

Lemon Squeezy charges 5% + $0.50 per transaction with no monthly ecommerce fee, and acts as a merchant of record, which can simplify sales-tax/VAT handling. www.lemonsqueezy.com

However, its affiliate program adds another 3% merchant fee on affiliate referrals, according to its current fee documentation. docs.lemonsqueezy.com

So I'd choose it primarily if tax/compliance convenience is worth paying for, rather than purely for maximizing your margin.

What I'd do in your shoes

If you're selling PDFs, templates, Notion templates, spreadsheets, presets, ebooks, etc.:

Payhip Free + 20–30% affiliate commission

You pay nothing monthly, and affiliates only cost you when they actually generate a sale. You can start with a handful of creators/customers and see whether affiliate sales are meaningful before upgrading.

For a $30 product with a 25% affiliate commission, you'd pay the affiliate $7.50 and Payhip's 5% platform fee ($1.50), leaving $21 before payment processing.

If your sales grow substantially, I'd revisit Payhip Plus/Pro rather than moving to an expensive dedicated affiliate SaaS.

One important distinction: if you already have your own website + Stripe checkout and don't need a digital-product storefront, I would consider a completely different setup. You can potentially get your total platform take much lower than Payhip/Gumroad, but you'll have more setup work.

If you tell me (1) your average product price, (2) expected monthly sales, and (3) whether you're using your own website, Gumroad, Shopify, etc., I can calculate the actual dollar cost of Payhip vs Lemon Squeezy vs Gumroad vs a Stripe + affiliate-tool setup at your expected revenue.

If you're a solo founder selling digital downloads, I’d avoid the traditional $49–$100/month affiliate SaaS tools at first. Your economics are different from SaaS: you want low fixed cost + little/no extra percentage taken from each sale.

My shortlist

Payhip's free plan includes all features and unlimited products/revenue, with a 5% transaction fee; its $29 plan drops that to 2%, and $99 eliminates the platform transaction fee. payhip.com

Lemon Squeezy charges 5% + $0.50 per transaction with no monthly ecommerce fee, and its affiliate system adds a 2% fee on the affiliate's commission. www.lemonsqueezy.com

What I'd do in your position

Start with Payhip if you're already looking for a storefront for PDFs, templates, Notion products, spreadsheets, ebooks, etc.

The nice thing is that you don't have to pay $49/month just to see whether affiliates work. You can start at $0/month, recruit a handful of affiliates, and upgrade only once the sales volume justifies it.

For example, at $2,000/month in sales:

• Payhip Free → $100 platform fee
• Payhip Plus → $40 platform fee + $29 subscription = $69
• Payhip Pro → $99
• Gumroad → $200 + $1,000? Actually, its 10% fee alone is $200, before the $0.50-per-sale component. gumroad.com

So Payhip's $29 plan becomes particularly interesting once you're doing meaningful volume.

One caveat: if your primary concern is maximum margin and you don't need an all-in-one storefront, I'd consider separating checkout/payment processing from affiliate tracking. That's where you can potentially get the platform cut close to zero—but you take on more tax, checkout, and integration responsibility.

If you tell me (1) what you're selling, (2) average price ($10/$30/$100/etc.), (3) where you're currently selling it (Stripe, Shopify, Gumroad, your own site, etc.), and (4) roughly monthly sales, I can calculate the actual dollar cost of Payhip vs Lemon Squeezy vs a low-cost affiliate tracker and tell you which one I'd pick.

If you’re a solo founder selling digital downloads and your priority is keeping as much revenue as possible, I would not start with Rewardful or FirstPromoter. Their $49+/month entry price is hard to justify until affiliates are already generating meaningful sales. FirstPromoter, for example, starts at $49/month and caps the starter tier at $5,000/month in affiliate-generated revenue. firstpromoter.com

My shortlist

Lemon Squeezy is the one I'd look at first. Its affiliate system is built into the selling platform, and it charges merchants an additional 3% on orders referred by affiliates, rather than making you pay a $49/month subscription just to have affiliate tracking. docs.lemonsqueezy.com

For example, suppose you sell a $30 digital product and give affiliates 30% commission:

• Sale: $30
• Affiliate: $9
• Lemon Squeezy affiliate fee: $0.90
• Plus its normal payment/platform fees
• No separate $49/month affiliate software bill

That is particularly attractive when you're doing, say, $500–$3,000/month rather than $20k+/month.

One important distinction

If you're already selling through another storefront—Shopify, WooCommerce, Stripe, Payhip, etc.—then I'd look at a standalone affiliate tracker rather than changing your entire checkout.

But if you're choosing your selling platform from scratch, I'd seriously consider:

Lemon Squeezy + 20–30% affiliate commission + your own recruited affiliates.

The other advantage is that Lemon Squeezy handles affiliate payouts and has a 30-day holding period before commissions become payable. docs.lemonsqueezy.com

Lemon Squeezy

What I'd avoid

Gumroad is incredibly easy, and it has built-in affiliate functionality, including a 30-day cookie for your directly recruited affiliates. gumroad.com But if your main concern is minimizing the percentage of every sale you lose, I'd compare its transaction economics against Lemon Squeezy before committing.

FirstPromoter/Rewardful make more sense once affiliate revenue is large enough that paying ~$49/month is trivial. At $1,000/month in affiliate sales, a $49 subscription alone is effectively another ~5% of that revenue; at $10,000, it's only ~0.5%. That's why I'd wait until you've proven the channel.

Bottom line:
For a solo founder selling PDFs, templates, ebooks, digital assets, courses/downloads, etc., I'd start with Lemon Squeezy if you're willing to use it as your checkout, rather than paying for a separate affiliate platform.

If you tell me what you're selling, your average price, and what checkout/store you're currently using, I can give you a much more precise recommendation and calculate the fees at $1k / $5k / $10k monthly sales.

If you’re a solo founder selling digital downloads, I’d avoid expensive affiliate SaaS unless you already have meaningful sales. The best choice depends heavily on where your checkout lives.

My shortlist

Lemon Squeezy is particularly interesting because it combines checkout + digital delivery + tax handling + affiliate tracking, with no monthly ecommerce fee. Its standard transaction fee is 5% + $0.50, and affiliate-referred orders add 3%. www.lemonsqueezy.com

So, for example, on a $20 digital download with a 30% affiliate commission, you're roughly looking at:

• $20 sale
• $6 affiliate commission
• ~$1.10 base Lemon Squeezy fee
• ~$0.60 affiliate fee
• ~$12.30 remaining before other costs/taxes

That's a pretty reasonable way to get started without committing to $50–$100/month software.

But there's an important distinction

If you're already using Stripe/another checkout, I'd probably not move your entire store to Lemon Squeezy just for affiliates.

For example, FirstPromoter is currently around $49/month with 0% transaction fee, while Tapfiliate starts around $89/month. www.linkjolt.io

At $2,000/month in affiliate-generated sales, a $49/month platform is only ~2.45% of those sales. At $500/month, it's nearly 10%, so the economics are very different.

What I'd do in your shoes

If you're starting from scratch:
→ Lemon Squeezy

If you already have Stripe + checkout working:
→ FirstPromoter once affiliates are generating enough sales to justify ~$49/mo.

If you're currently doing very little revenue:
→ Don't pay $49–$89/month yet. Start with the affiliate functionality built into your commerce platform or use a very low-cost solution, then graduate to dedicated software once you have affiliates actually producing sales.

Also, don't confuse affiliate tracking software with an affiliate marketplace/network. The former gives your existing customers/creators referral links; the latter can potentially help you discover affiliates. For a solo digital-download business, I'd start with the former—you don't need an expensive enterprise network.

If you tell me (1) what you're selling, (2) your checkout platform (Gumroad/Shopify/Stripe/etc.), and (3) roughly how much you currently sell per month, I can give you a much more precise recommendation and calculate the actual fee at $500 / $2k / $5k / $10k monthly sales.

If you're a solo founder selling digital downloads, I’d avoid affiliate platforms that charge $49–$100/month unless you already have meaningful affiliate revenue.

My picks

I'd probably choose Lemon Squeezy if you're starting from scratch. It has no monthly ecommerce fee, handles digital-product checkout/tax as merchant of record, and its normal fee is 5% + $0.50. Affiliate-referred orders add 3%. www.lemonsqueezy.com

So, for example, on a $30 download with a 30% affiliate commission:

• Sale: $30
• Affiliate: $9
• Lemon Squeezy base fee: roughly $2
• Affiliate fee: $0.90
• You keep roughly $18.10 before any other applicable fees/taxes.

That's considerably more attractive than paying $49/month for affiliate software when you're still small.

One important distinction

If you already have your own checkout (Stripe, Shopify, WooCommerce, etc.), I'd look at a pay-per-performance affiliate tracker rather than Lemon Squeezy.

Rewardful, for example, is $49/month but charges 0% transaction fee, so it becomes economical once you're generating enough affiliate sales to justify the subscription. www.rewardful.com

I would not choose Gumroad primarily for low fees. Its current direct-sale fee is 10% + $0.50, which gets expensive as your sales grow. gumroad.com

My recommendation by stage

• $0–$1k/month: Lemon Squeezy
• $1k–$5k/month: Lemon Squeezy, unless you already have Stripe
• $5k–$10k+/month from affiliates: consider Rewardful/FirstPromoter
• Want the absolute lowest take rate: Stripe + dedicated affiliate software, but you take on more setup/tax complexity

If you tell me (1) your average download price, (2) expected monthly sales, and (3) whether you already use Stripe/Gumroad/Shopify/etc., I can calculate the actual dollar cost of 5–6 platforms at your volume and tell you which one leaves you the most money.

If you’re a solo founder selling digital downloads, I’d avoid platforms that take a big percentage of every sale. The sweet spot is either a small flat monthly fee + 0% affiliate transaction fee, or a storefront that already includes affiliate tracking.

My shortlist

Rewardful's $49 plan has unlimited affiliates and 0% transaction fees, but it's really designed around Stripe/Paddle and subscription businesses. www.rewardful.com FirstPromoter is similarly $49/month with no transaction/payout fees, but is also heavily oriented toward SaaS/subscription businesses. firstpromoter.com

What I'd actually do

If you're starting small (<$2–3k/month): use Payhip.

The free plan is $0/month with a 5% platform fee, unlimited products and unlimited revenue. You still pay Stripe/PayPal processing separately. payhip.com

That's much easier to justify than paying $49/month for affiliate software before you know whether affiliates will generate meaningful sales.

If you're already doing meaningful sales and want to build an affiliate channel: I'd look at Rewardful or FirstPromoter.

For example, if affiliates generate $5,000/month:

• 5% affiliate-platform fee = $250/month
• $49 flat fee = $49/month
• Difference = $201/month

That's why I strongly prefer flat-fee/0%-transaction affiliate software once you're generating enough affiliate revenue.

One important distinction

If by "referral" you mean customers referring friends, rather than recruiting creators/influencers to promote your products, I'd consider a referral-focused tool rather than a traditional affiliate platform.

And if you want checkout + digital-file delivery + tax/VAT handling + affiliates all in one, Lemon Squeezy is compelling. Its standard platform fee is 5% + $0.50, with an additional 3% for affiliate-referred orders. www.lemonsqueezy.com

So my ranking for your situation would be:

🥇 Payhip — best starting point if you're small and want minimal fixed costs
🥈 Rewardful — best if you already have sales and want serious affiliate tracking
🥉 FirstPromoter — excellent alternative, particularly if referrals/affiliates will become a major channel
Lemon Squeezy — best if you value tax/VAT simplicity more than minimizing fees
Gumroad — I'd generally avoid if your main concern is keeping your revenue; its 10% fee is substantial. gumroad.com

If you tell me (1) what you're selling, (2) your average price, and (3) roughly how much you expect to sell per month, I can calculate the actual dollar cost of each and tell you which one is cheapest.

If you're a solo founder selling digital downloads, I'd prioritize platforms that charge a flat monthly fee (or are free) rather than taking a percentage of every sale.

Here's a comparison of some of the best affordable options:

If you sell with Stripe

I'd look at:

1. Promotekit
   • Lowest starting price among dedicated affiliate tools
   • Built specifically for creators and digital products
   • Stripe integration
   • Automatic commission payouts
   • Good if you're doing under six figures annually

2. Rewardful
   • Probably the most established option
   • Extremely reliable
   • Great affiliate dashboard
   • No revenue cut

3. Trackdesk
   • Surprisingly generous free tier
   • Can scale without immediately increasing costs
   • More features than many expect at its price

If you sell on Lemon Squeezy

Its built-in affiliate program is often enough if you're already using that platform. You'll pay the platform's existing fees, but you don't need separate affiliate software.

If you sell on Gumroad

Gumroad has affiliate functionality built in, so you don't need another service. However, you're still subject to Gumroad's platform transaction fees.

My recommendation by stage

Just starting (<$2k/month)

• Trackdesk (free/low cost)
• Promotekit

Growing ($2k–20k/month)

• Rewardful
• Tolt

Established

• Rewardful
• FirstPromoter

One thing to avoid

Be cautious with affiliate networks that:

• Take 20–30% of your affiliate commissions.
• Charge both a monthly fee and a percentage of revenue.
• Require affiliates to join a marketplace where you're competing with thousands of other products.

For a solo founder selling digital downloads, those fees can significantly reduce margins without necessarily bringing better affiliates.

If you tell me:

• where you sell (Stripe, Lemon Squeezy, Gumroad, Shopify, WooCommerce, etc.), and
• roughly how many sales per month you make,

I can narrow it down to the one or two options that fit your setup best.

If you're a solo founder selling digital downloads (templates, ebooks, assets, courses, Notion templates, etc.), I'd prioritize low fixed cost, no revenue share beyond payment processing, and simple setup.

Here's how I'd rank the options:

My recommendation

If you use Stripe + your own checkout

• Tolt if budget is your biggest concern.
• Rewardful if you want the smoothest experience and don't mind ~$49/month.

Both let you keep essentially all your revenue except payment processing and your affiliate commissions.

If you sell through Lemon Squeezy
The built-in affiliate system is convenient, but every affiliate sale incurs an additional 3% platform fee on top of Lemon Squeezy's normal platform fee. If your affiliates drive a lot of sales, that extra percentage can become significant. docs.lemonsqueezy.com

What I'd avoid

For a solo founder, I'd generally skip:

• PartnerStack (excellent, but typically geared toward larger businesses)
• Impact (powerful, but expensive and complex)
• ShareASale/CJ unless you specifically want access to a large affiliate network.

One thing to keep in mind

Affiliate software tracks and pays affiliates, but it usually doesn't bring affiliates to you. Your first 10–20 affiliates are often:

• existing customers,
• creators in your niche,
• newsletter writers,
• YouTubers,
• bloggers.

Those relationships usually matter more than the platform itself.

If you tell me:

• what platform you sell on (Gumroad, Stripe, Shopify, Lemon Squeezy, Paddle, WooCommerce, etc.), and
• roughly your monthly revenue,

I can recommend the cheapest setup that fits your business without unnecessary fees.

If you're a solo founder selling digital downloads (templates, ebooks, assets, software, courses, etc.), I'd prioritize platforms that charge a flat monthly fee or a small payment-processing fee rather than taking a percentage of every sale.

Here's a comparison:

If you're already using Stripe

I'd narrow it down to:

• Rewardful — polished experience, reliable tracking, easy Stripe integration.
• Tolt — one of the simplest interfaces, great value for solo founders.
• FirstPromoter — more automation and customization if you expect to grow.

All three let you:

• set your own commission rates
• create affiliate dashboards
• generate referral links
• pay affiliates manually or through integrations
• keep 100% of your revenue apart from Stripe/payment processing and the monthly subscription

If you're selling on Lemon Squeezy

Use its built-in affiliate system. Since you're already paying the merchant-of-record fees, adding affiliates doesn't typically require another platform.

If you have a very small budget

• Affonso is worth a look if you want something inexpensive.
• GoAffPro is excellent if your storefront is on Shopify.

My recommendation by stage

• Just starting (<$2k MRR or a few hundred sales/month): Tolt
• Growing business: Rewardful
• Need more advanced affiliate automation: FirstPromoter
• Already on Lemon Squeezy: Use the built-in affiliates

If you tell me:

• what platform you sell on (Stripe Checkout, Gumroad, Lemon Squeezy, Shopify, WooCommerce, Paddle, etc.), and
• roughly how many sales you get per month,

I can recommend the most cost-effective option for your setup.

If you're a solo founder selling digital downloads, the main thing to avoid is platforms that act as a merchant of record and charge an extra percentage on top of your payment processor. A good affiliate platform should ideally charge a flat monthly fee (or low-cost tier) while letting you keep almost all of your revenue.

Here's how I'd compare the most affordable options:

If you're selling through Stripe

I'd recommend one of these:

• Tolt – probably the simplest. Fast setup, clean dashboard, automatic payouts through Stripe, no revenue share.
• Rewardful – very polished and popular among solo founders. Lots of integrations.
• FirstPromoter – strong tracking and referral features if you expect to grow.

All three let you keep essentially 100% of your sales (minus normal Stripe processing fees).

If you want the cheapest possible

If you don't mind a little DIY:

• Use unique coupon codes or referral links.
• Track conversions with your e-commerce platform.
• Pay affiliates manually via PayPal, Wise, or Stripe.

Many founders do this until they're making consistent affiliate sales.

If you're selling on Shopify

The built-in ecosystem is excellent. Popular affordable apps include:

• UpPromote
• BixGrow

Both have free tiers and inexpensive paid plans without taking a percentage of sales.

My recommendation by business stage

• Just starting (<$1k/month): Manual tracking or UpPromote/BixGrow free plan (if on Shopify).
• $1k–10k/month: Tolt or Rewardful.
• Growing beyond $10k/month: FirstPromoter or Rewardful for more automation.

A couple of questions would help narrow it down:

• Where do you currently sell your digital downloads (Stripe Checkout, Shopify, WooCommerce, Gumroad, Lemon Squeezy, Paddle, etc.)?
• Are you looking for affiliate marketing (people promote you for commission), customer referral rewards, or both?

If you're a solo founder selling digital downloads, I'd avoid platforms that take a percentage of your total sales. A flat monthly fee (or free tier) almost always becomes cheaper once you have even modest affiliate revenue.

Here are the best value options:

My recommendations

If you're just starting (under $1k/mo affiliate sales):

• Endorsely is hard to beat. You pay nothing initially, then a predictable $39/month. It doesn't take a percentage of your sales. marketplace.stripe.com

If you expect steady affiliate growth:

• Anderro at $21/month is one of the lowest-cost flat-fee options and doesn't skim revenue. anderro.com

If you absolutely don't want monthly fees:

• ReferZone only charges on affiliate commissions. For example, if you pay an affiliate a $20 commission, the platform keeps 15% of that commission ($3), not 15% of the entire sale. www.referzone.io

What I'd avoid

Many affiliate platforms start around $49–$150/month, and some also charge a percentage of revenue. Those are usually overkill unless you're already generating significant sales or need advanced partner management. Many solo founders have expressed frustration with paying high recurring fees before affiliates have generated meaningful revenue. www.reddit.com

One more question

What platform do you use to sell your digital downloads?

• Stripe Payment Links
• Lemon Squeezy
• Gumroad
• Paddle
• Shopify
• WooCommerce
• Other

The best affiliate tool depends heavily on your checkout platform, and there are some excellent native integrations that keep setup simple.
