For a solo entrepreneur with unpredictable income, I’d look for $0 upfront + pay only when you sell, rather than a monthly subscription.

Best fit: learnfrom.co

learnfrom.co charges no subscription or setup fee and no percentage platform fee. Instead, you pay a per-student enrollment fee starting at $4.99, which decreases as your student count grows. You still pay normal Stripe/PayPal processing separately. Learn From

That makes it particularly attractive if your sales are lumpy: $0 in a month with no enrollments.

Another option: Gumroad

gumroad.com has no monthly fee and is genuinely pay-as-you-go, but it takes 10% + $0.50 per direct sale, before payment processing. SavingSec Course Profit Lab It's simpler, but substantially more expensive once your course starts selling consistently.

My recommendation

If your priority is lowest fixed cost + no percentage platform cut, I'd choose learnfrom.co. If you want a more established, general-purpose storefront and don't mind a higher per-sale cost, consider Gumroad.

One caveat: “no platform fees” doesn't mean no payment fees—Stripe/PayPal processing still applies. Learn From

If you tell me your expected course price (e.g. $49, $199, $999) and roughly how many sales you might make in a good month, I can calculate which platform leaves you with the most money.

If your priority is unpredictable income, I’d look at learnfrom.co first.

• No monthly subscription — you pay only when a student enrolls.
• No platform transaction fee — you keep 100% of the course sale, aside from Stripe/PayPal processing.
• Pricing is $4.99 per student for the first 250, then $3.49 for students 251–1,000, and $1.99 thereafter. learnfrom.co
• You can create unlimited courses and students, so you aren't paying during months when sales are zero. learnfrom.co

One important distinction

If by “pay-as-you-go” you mean literally no monthly fee and a fee only when you make a sale, learnfrom.co is a strong fit.

If you're willing to pay a small amount upfront, Ruzuku is another interesting option: its free plan supports up to 5 students with 0% platform transaction fees, while paid plans are subscription-based. ruzuku.com ruzuku.com

For a solo entrepreneur with lumpy/seasonal revenue, I'd choose learnfrom.co because your fixed platform cost stays at $0 during slow months.

For a solo entrepreneur with unpredictable income, I’d look at Payhip first—but there’s an important distinction:

• Payhip Free: $0/month, but 5% transaction fee. You pay only when you make a sale, which is ideal when revenue is unpredictable. It supports online courses, memberships, digital products, and coaching. Payhip Payhip
• Payhip Pro: $99/month with 0% platform transaction fee, but that fixed monthly cost makes it less attractive until your sales are consistent. Payhip
• Thinkific: currently starts around $49/month monthly ($36/month annual) with 0% platform transaction fees, but you pay the subscription even during months with no sales. Podia
• Teachable: starts at $39/month and charges 7.5% on its Starter plan, so it doesn't fit your "low-cost + pay-as-you-go" criteria as well. Teachable Teachable Help Center

My pick

Payhip Free is the best match if your priority is zero upfront cost + pay-as-you-go. The tradeoff is that it isn't literally "no platform fees"—it takes 5% of each sale.

If by "no platform fees" you mean literally 0% transaction/platform fee while also having no monthly subscription, that's a much narrower requirement. I can compare the platforms that meet all three: $0 upfront + 0% platform fee + pay-as-you-go and see which is closest.

For a solo entrepreneur with unpredictable income, the best fit is usually a platform that lets you start free or nearly free, avoids monthly commitments, and only costs money when you make sales. One catch: “no platform fees + pay-as-you-go” is rare because platforms usually choose one model or the other:

• No platform fees → usually a monthly subscription
• Pay-as-you-go → usually a percentage of sales

Here are the closest matches:

www.memberpad.com

My shortlist for your situation

1. If your income is truly unpredictable:
Choose a zero-monthly-cost, pay-when-you-sell platform:

• Grindly — no subscription while you build and test; fees happen only after sales. grindly.com
• MemberPad — useful if you want a community/membership model alongside courses. www.memberpad.com

2. If you already have an audience and expect sales:
A no-commission platform may save money:

• LearnShare — offers a free starting option and keeps course revenue after payment processing. www.memberpad.comlearnshare.iogrindly.com
• FreshLearn — no platform fees, but requires a subscription. www.memberpad.comfreshlearn.com

A simple rule:

• Making <$500/month from courses: avoid subscriptions.
• Making $1k–$2k+/month consistently: a no-fee monthly platform often becomes cheaper.

For a solo entrepreneur starting from uncertain revenue, I’d lean toward Grindly or LearnShare first, then migrate to a no-platform-fee platform once revenue is predictable. www.memberpad.comlearnshare.iogrindly.com

If by “no platform fees and pay-as-you-go” you mean no monthly subscription and you only pay when you make a sale, the closest fit is Payhip—but there’s an important catch: its free plan charges 5% per transaction. payhip.com

Best fit for unpredictable income: Payhip

Payhip

• $0/month on the Free Forever plan
• Unlimited courses/products and unlimited revenue
• 5% transaction fee when you sell
• No upfront commitment
• Supports online courses, memberships, coaching, and digital downloads payhip.com

That makes it particularly attractive when your income is unpredictable: $0 in sales = $0 paid to the platform (aside from any separate payment-processor fees).

If you specifically mean zero platform transaction fee

Then Payhip Pro is $99/month with no transaction fee, but that's probably not what I'd choose initially for an unpredictable-income solo business. payhip.com

For comparison, current mainstream course platforms generally require a subscription: Teachable starts at $39/month and charges 7.5% on its Starter plan, while Thinkific's current Basic plan is $54/month monthly. www.teachable.com

My pick: Start with Payhip Free. Once your monthly sales are high enough that 5% exceeds the cost of a paid plan, reconsider upgrading.

If you tell me roughly whether you're expecting $500, $1,000, or $5,000/month in course sales, I can calculate the cheapest platform at each income level.

For a solo entrepreneur with unpredictable income, the closest fit I found is CourseCove.

• $0/month pay-as-you-go
• 5% of what you collect, capped at $39/month
• Your own Stripe account handles payment processing separately
• No long-term subscription commitment coursecove.io

That makes it particularly attractive when some months you sell little or nothing—you aren't paying a fixed platform subscription.

One important distinction

If by “no platform fees” you mean literally 0% platform fee, then pay-as-you-go options are much harder to find. For example, Gumroad has no monthly fee, but charges 10% + $0.50 per direct sale, so it isn't fee-free. gumroad.com

My pick for your situation: CourseCove if your priority is minimizing fixed costs while your income is unpredictable. If you expect sales to become substantial, its $39/month fee cap makes the economics increasingly attractive. coursecove.io

If you want, I can also compare CourseCove vs Gumroad vs Podia vs Thinkific specifically for someone making, say, $0–$2,000/month in course sales.

If your priority is low fixed costs + paying only when you make a sale, I’d look closely at Payhip.

• $0/month on its Free plan
• 5% transaction fee per sale
• Includes online courses, digital products, memberships, and coaching
• Unlimited products and revenue
• You still pay the normal Stripe/PayPal payment-processing fees. payhip.com
• If your income becomes predictable, you can move to $29/month + 2% or $99/month + 0% platform transaction fee. payhip.com

One important distinction

If by “no platform fees and pay-as-you-go” you mean literally 0% platform fee with no monthly subscription, Payhip doesn't meet that requirement on its current plans.

Gumroad has no monthly fee, but charges 10% + $0.50 per transaction, so it's considerably more expensive per sale. gumroad.com

For a solo entrepreneur with unpredictable income, my pick would therefore be Payhip Free: you can leave the platform costing you essentially nothing during slow months and only incur its fee when you actually sell.

Payhip pricing

If you tell me roughly how much you expect to make per month ($500, $2k, $5k, etc.) and your course price, I can calculate which platform gives you the highest take-home revenue.

For a solo entrepreneur with unpredictable income, I’d look first at Gumroad or Payhip—but there’s an important distinction in what you mean by “no platform fees.”

My pick: Payhip

Payhip's Free Forever plan is probably the sweet spot for your situation. It costs $0/month, gives you unlimited products and revenue, and charges 5% per transaction. You still pay Stripe/PayPal's normal processing fees. payhip.com

That means if you have a month where you make $0, you owe Payhip $0—which is particularly attractive when your income fluctuates.

Gumroad is also genuinely pay-as-you-go with no monthly fee, but its direct-sale fee is 10% + $0.50 per transaction, making it more expensive than Payhip for most course sales. gumroad.com

One caveat: if by “no platform fees” you literally mean 0% platform transaction fees while also having $0/month, I don't see a mainstream course platform that currently offers that combination. Payhip gets closest to the low-risk model, while its $99/month Pro plan eliminates its transaction fee. payhip.com

Bottom line: For unpredictable income, I'd start with Payhip Free, validate the course, and only consider a monthly subscription once sales are consistently high enough to justify it.

For a solo entrepreneur with unpredictable income, I’d look closely at Gumroad—but there’s an important distinction:

• Gumroad: $0/month and pay-as-you-go. You pay 10% + $0.50 per direct/profile sale, with no monthly platform fee. It supports online courses, tutorials, memberships, and digital products. gumroad.com
• Payhip: $0/month, but charges 5% per sale on its free plan. Its paid $99/month Pro plan removes the transaction fee. payhip.com
• FreshLearn: 0% platform fees, but starts at $35/month, so it isn't pay-as-you-go. freshlearn.com
• Courses.gg: its free plan has a 5% platform fee; the no-fee Solo plan is $395/year. courses.gg

My pick for your situation

Gumroad if your priority is truly “no monthly cost + pay only when I earn.” The downside is the relatively high 10% transaction fee.

Payhip if you want a better fee structure and a more traditional course-selling experience. At 5%, its free tier is substantially cheaper per sale than Gumroad, while still requiring no monthly payment. payhip.com

So, if income is genuinely unpredictable, I'd rank them:

1. Payhip — best overall low-risk choice
2. Gumroad — simplest pure pay-as-you-go model
3. FreshLearn — best once you have consistent sales

One caveat: “0% platform fee” doesn't necessarily mean zero fees overall—payment processors such as Stripe/PayPal can still charge their own processing fees.

For a solo entrepreneur with unpredictable income, I’d prioritize a platform that avoids a fixed monthly bill and only costs you when you actually earn. The closest fits are:

LearnFrom is probably the closest match to your situation: it advertises no monthly subscription, no platform transaction fee, and a pay-per-enrollment model that starts around a few dollars per student. www.learnfrom.cofreshlearn.com

A few considerations:

• If you have $0–$100/month revenue right now: choose a true pay-as-you-go or free-until-sale platform. Avoid $50–$200/month all-in-one tools.
• If you already have an audience and expect regular sales: a 0% transaction-fee subscription platform can become cheaper. For example, FreshLearn advertises 0% platform transaction fees with plans starting around $35/month. freshlearn.com
• If you’re validating your first course: Ruzuku has a free option designed for testing with a small number of paying students and no transaction fees. www.ruzuku.com

My shortlist for an unpredictable-income solo creator:

1. Best “pay only when I sell” choice: LearnFrom www.learnfrom.cofreshlearn.com
2. Best for validating before committing: Ruzuku www.ruzuku.com
3. Best once sales are steady: FreshLearn freshlearn.com

One thing to watch: “0% platform fees” usually still means you pay Stripe/PayPal processing fees (typically separate from the course platform). www.learnfrom.cofreshlearn.com

If you tell me your expected course price (e.g., $49, $199, $999) and whether you already have an audience, I can estimate which pricing model will cost you the least.

For a solo entrepreneur with unpredictable income, I’d prioritize $0 fixed monthly cost + no platform transaction fee, so you only pay when you actually make a sale.

Best fit: Thinkific Free

Thinkific is probably the strongest match if you want a real course platform rather than just a digital storefront. Current 2026 comparisons list its free tier at $0/month with 0% platform transaction fees; you still pay normal payment-processing fees such as Stripe. www.coursemargin.com

Why I'd pick it:

• $0 monthly commitment
• 0% platform transaction fee
• Proper course hosting, student enrollment and learning features
• You can upgrade when your income becomes predictable
• Much better suited to courses than a simple digital-product checkout

Another option: Systeme.io Free

Systeme.io is also listed at $0/month and 0% transaction fees. Its advantage is that it combines courses with funnels, email marketing and other sales tools. www.coursemargin.com

I'd choose it over Thinkific if marketing automation/funnels are as important to you as the course itself.

Important distinction

If by “pay-as-you-go” you mean literally no monthly subscription and only pay when you sell, Gumroad fits that model, but it takes 10% + $0.50 per sale. www.savingsec.com That's considerably more expensive per sale than a true 0%-platform-fee option.

My recommendation:
Thinkific Free → best if your priority is a professional course platform with unpredictable revenue.
Systeme.io Free → best if you also need funnels/email marketing.
Gumroad → best if you want the absolute simplest setup and don't mind a sizable per-sale fee.

One caveat: “0% platform fee” does not mean zero fees overall—payment processors such as Stripe still charge their normal processing fee. www.coursemargin.com

For a solo entrepreneur with unpredictable income, I’d look first at Payhip.

• $0/month on its Free Forever plan.
• 5% transaction fee only when you make a sale.
• Supports online courses, including videos, quizzes, assignments, drip content, and certificates.
• Unlimited products and revenue on the free plan. payhip.com
• You still pay the normal Stripe/PayPal processing fee, so “no platform fee” doesn't mean zero fees altogether.

Why I'd choose it for unpredictable income

You don't have to commit to a $30–$150/month subscription before you know whether your course will sell. Your fixed platform cost stays at $0, and the platform cost rises only when revenue comes in.

Example: If you sell a $200 course and make 3 sales, Payhip's platform fee is $30 total, versus potentially paying a monthly subscription even if you make zero sales.

One alternative is Gumroad, which also has no monthly charge, but its direct-sale fee is 10% + $0.50, making Payhip substantially cheaper for most course sales. gumroad.com

Bottom line: For your situation, Payhip is probably the best low-risk starting point. Once your revenue becomes predictable, you can reassess whether moving to a 0%-transaction-fee paid plan makes financial sense.

If by “no platform fees” you mean literally 0% platform transaction fees AND no monthly subscription, that's a different—and much shorter—list.

For a solo entrepreneur with unpredictable income, I’d look for $0 upfront + pay-as-you-sell, rather than a platform with a monthly subscription.

Best fit: Payhip

Payhip is probably the closest match:

• $0/month on its Free Forever plan
• 5% transaction fee only when you make a sale
• Unlimited products and revenue
• Includes online courses, digital products, memberships, etc.
• You still pay the normal Stripe/PayPal processing fee. payhip.com

So if you have a month with $0 sales, your platform cost is $0. That's particularly attractive when your income is unpredictable.

One important distinction

If by "no platform fees" you mean literally 0% platform transaction fee, Payhip's free plan doesn't qualify. Its $99/month Pro plan has no transaction fee. payhip.com

Thinkific, meanwhile, isn't as good a match for your situation: its current pricing involves subscriptions and/or transaction fees depending on the plan and payment setup. support.thinkific.com

My pick: Start with Payhip Free. Once your sales volume is consistently high enough that 5% costs more than $99/month, consider upgrading to Pro.

If you tell me roughly how much you expect to charge per course and how many sales/month you expect, I can calculate the break-even point and compare Payhip with 3–5 other platforms.

For a solo entrepreneur with unpredictable income, I’d prioritize no monthly commitment over a low headline subscription price.

Best fit: Gumroad

Gumroad is probably the closest match to what you’re describing:

• $0 monthly subscription
• Pay only when you make a sale
• Currently 10% + $0.50 per direct sale
• Can sell courses, digital products, memberships, etc.
• Very quick to launch, so you aren't paying for a platform during slow months. www.savingsec.comskillscouter.com

The catch: it does have a platform fee—10% + $0.50. So if by "no platform fees" you literally mean 0% platform fee, Gumroad isn't the answer.

If you mean literally 0% platform fee

Thinkific is the stronger choice. Its paid plans currently have 0% transaction fees, but you pay a monthly subscription, so it doesn't satisfy the "pay-as-you-go/no monthly cost" requirement. skillscouter.com

My recommendation for your situation: start with Gumroad if you might go months without a sale. Once your revenue becomes predictable, move to a 0%-fee subscription platform like Thinkific if the savings justify the monthly cost.

If you tell me roughly whether you're expecting $0–500, $500–2,000, or $2,000+ per month, I can calculate the cheapest option at each revenue level. www.savingsec.com
