If your income is unpredictable, Payhip’s free plan is probably the closest match to what you’re describing: $0/month, no upfront commitment, and pay-as-you-go. It supports online courses as well as digital products. The tradeoff is a 5% transaction fee on the free plan. Payhip Payhip

Gumroad also has no monthly charge and explicitly supports courses, but its direct-sale fee is 10% + $0.50, making Payhip cheaper on each sale under its free plan. Gumroad

One important distinction: if by “no platform fees” you mean literally 0% platform transaction fees, rather than “no monthly subscription,” then Payhip Free doesn't qualify. Thinkific currently offers 0% platform transaction fees when using Thinkific Payments, but you pay a monthly subscription. courseprofitlab.com podia.com

For a solo entrepreneur who might make $0 one month and $1,000 the next, I'd focus on Payhip vs. Gumroad because neither requires you to carry a monthly subscription during slow months.

If by “no platform fees + pay-as-you-go” you mean no monthly subscription and you only pay when you make a sale, the closest fit is Gumroad.

• Gumroad: $0/month; 10% + $0.50 per direct sale. There’s also a 30% fee when a customer discovers you through Gumroad’s marketplace. It supports online courses. Gumroad Gumroad
• Payhip: $0/month, but 5% per sale on its Free Forever plan, plus Stripe/PayPal processing. It supports courses and gives you all features on the free plan. Payhip Payhip
• Thinkific: Some current sources report a $0 plan with 0% platform transaction fees, but pricing/plan availability has changed, so I would verify the current official plan before choosing it. CourseMargin

For unpredictable income

I'd focus on Payhip vs. Gumroad:

So Payhip currently has the lower per-sale platform fee, while Gumroad has the advantage of a very simple creator storefront and marketplace discovery. Payhip Gumroad

If you tell me your course price (e.g. $49/$99/$299) and expected sales per month, I can calculate which one leaves you with more money at your actual income level.

For a solo entrepreneur with unpredictable income, you’ll usually want a platform with:

• $0 upfront or very low monthly commitment
• No platform revenue share/transaction fee
• Ability to upgrade only when sales justify it
• Your own Stripe/PayPal account so you control payouts

A few options that fit:

My shortlist for your situation

1. If you have not validated your course idea yet:

Start with Ruzuku or LearnShare. You can test demand without locking yourself into a large monthly bill. Ruzuku LearnShare

2. If you already have an audience and want a professional setup:

Consider FreshLearn. It offers a more complete “business in a box” approach while avoiding a cut of your sales. FreshLearn

3. If you want the lowest ongoing cost and can handle a simpler setup:

Look at Coursio or Sikhaku. Coursio Sikhaku

One caution: “no platform fees” usually does not mean “no fees at all.” You’ll typically still pay payment processor fees from services like Stripe or PayPal.

For a solo entrepreneur with irregular revenue, I’d generally avoid platforms that require a high fixed monthly payment before you have consistent sales. A good path is: free/low-cost validation → first sales → upgrade only when revenue supports it.

If by “no platform fees + pay-as-you-go” you mean no monthly subscription and you only pay when you make a sale, the best fit is generally Gumroad—but it’s not a traditional full-featured course platform.

• Gumroad: $0/month; you pay 10% + $0.50 per sale. Good for testing a course when income is unpredictable. SavingSec Teachable
• Thinkific Basic: currently about $40/month on annual billing, with 0% platform transaction fees when using Thinkific Payments—but that's not pay-as-you-go. Teachable Course Profit Lab
• Teachable Starter: about $29/month annually + 7.5% per sale, so it isn't truly no-platform-fee either. Teachable
• Podia Mover: about $42/month annually + 5% per sale. Teachable

My pick for your situation

Start with Gumroad if your revenue is genuinely unpredictable. You avoid a recurring bill during months when you sell nothing. The tradeoff is the relatively high 10% fee and fewer dedicated course/LMS features.

If you're expecting consistent course revenue of roughly $800–$1,000+/month, I'd start looking at Thinkific instead: the fixed monthly cost becomes easier to justify, and you keep more of each sale. toolincomelab.com

If you tell me your expected course price and roughly how many sales you might make in a good vs. bad month, I can calculate the cheapest option for your specific income pattern.

If by “no platform fees and pay-as-you-go” you mean no monthly subscription and only pay when you make a sale, Payhip is probably the closest fit for a solo entrepreneur with unpredictable income.

• Payhip: $0/month on its Free plan, unlimited products/revenue, with a 5% transaction fee per sale. That means no fixed cost during months when you make nothing. Podia
• Thinkific: no platform transaction fee on its Basic plan, but it costs $54/month ($40/month annually), so it isn't truly pay-as-you-go. Thinkific
• Teachable: its cheapest plan is $39/month plus a 7.5% transaction fee, so it's less attractive for unpredictable income. Teachable Help Center Teachable
• Podia: starts at $49/month + 5% transaction fee, so again you have a fixed monthly cost. Podia

My pick for your situation

Payhip makes the most sense if your priority is minimizing risk when sales are inconsistent. You can leave the store running at $0/month and only pay the platform when you actually sell something. The trade-off is the 5% fee per sale.

If by “no platform fees” you literally mean 0% fee on each sale, then there isn't a strong low-cost pay-as-you-go option among the major course platforms I found; the 0% options generally require a monthly subscription. Teachable Thinkific

payhip.com Podia

For a solo entrepreneur with unpredictable income, I’d prioritize no monthly subscription + no platform percentage, so you don’t pay during slow months.

A strong fit is learnfrom.co:

• $0 upfront — no subscription or setup fee.
• No platform transaction fee — you keep 100% of course sales, aside from Stripe/PayPal’s normal payment-processing fees.
• Pay-as-you-go — you pay only when a new student enrolls.
• Pricing starts at $4.99 per student, dropping to $3.49 after 250 students and $1.99 after 1,000.
• Unlimited courses and students.
• Stripe and PayPal supported. learnfrom.co

My pick

learnfrom.co is probably the closest match to what you're describing. The important distinction is that it has a per-student fee rather than a percentage of your revenue, while having no monthly bill.

For example, if you make $0 in a month, your platform cost is $0. If you sell a $100 course to one student, the platform fee starts at $4.99, plus the payment processor's fee.

Another option worth looking at is CourseLink.to, which advertises no monthly fees and no platform fees on course sales, although I'd want to verify its exact pay-as-you-go economics before choosing it. courselink.to

If you tell me roughly how much you expect to charge per course and how many students you might get per month, I can compare the cheapest options numerically for your situation.

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

payhip.com offers a Free Forever plan at $0/month, with a 5% transaction fee only when you make a sale. It supports online courses, memberships, digital downloads, and coaching. Payhip Payhip

Why it fits unpredictable income

• $0 fixed monthly cost — no revenue means no platform subscription.
• Pay-as-you-go — you pay the 5% platform fee when you sell.
• Unlimited products and revenue on the free plan. Payhip
• You can sell online courses, not just PDFs or downloads.
• You can upgrade later to $29/month + 2% or $99/month with 0% platform fee if your sales become consistent. Payhip

For comparison, mainstream course platforms such as Thinkific now start around $54/month monthly ($40/month annually), although Thinkific has no platform transaction fee on its Basic plan when using Thinkific Payments. Thinkific Podia

Bottom line: If your priority is “I don't want a bill during months when I make nothing,” Payhip is probably the best fit. The trade-off is that its course-building experience is less specialized than dedicated LMS platforms.

If you tell me roughly whether you expect $0–$500, $500–$2,000, or $2,000+ per month, I can calculate which platform would actually cost you the least.

For a solo entrepreneur with unpredictable income, you probably want to avoid platforms that charge $50–$200/month before you have sales. The best fit is usually a no-monthly-fee or pay-only-when-you-sell model.

Here are the strongest options:

My top pick for your situation: LearnFrom

learnfrom.coWhy it fits a solo entrepreneur with uneven cash flow:

• $0 upfront monthly cost
• Create courses before paying anything
• Pay only when a student enrolls
• No platform percentage taken from your course revenue (payment processors like Stripe/PayPal still charge their normal fees) learnfrom.co

The tradeoff: per-student fees can become more expensive than a subscription once you have many students.

Best alternative: Ruzuku

RuzukuGood if you are validating your first offer:

• Free plan available
• 0% transaction fees
• Can sell courses and connect your own payment processor
• Free tier is limited (for example, by number of paying students) Ruzuku

When to switch to a subscription platform

Once you consistently make enough course revenue to justify a monthly bill, platforms with 0% transaction fees can make more sense. For example, FreshLearn advertises no platform fees and a paid plan starting around $35/month. FreshLearn

Simple rule of thumb:

• $0–$500/month course income: choose pay-as-you-go (LearnFrom/Ruzuku-style)
• $500–$3,000+/month: compare low-cost subscriptions
• $3,000+/month: prioritize branding, email marketing, automation, and student experience

If you tell me your course type (coaching, video lessons, cohort, downloads, membership, etc.) and expected student count, I can narrow it down to the cheapest fit.

If by “no platform fees” you mean no monthly subscription and you only pay when you make a sale, I’d look at Payhip first.

• Payhip Free: $0/month, with a 5% transaction fee. It supports online courses, digital products, memberships, and coaching. Payhip Payhip
• Payhip Plus: $29/month + 2% transaction fee.
• Payhip Pro: $99/month + 0% platform transaction fee. Payhip

For a solo entrepreneur with unpredictable income, the Free plan is attractive because you have no fixed monthly cost when you make $0.

One important distinction

If you mean literally 0% platform fee AND pay-as-you-go/no monthly fee, the mainstream platforms I checked don't really offer that combination. For example, Thinkific Basic has no platform transaction fee when using Thinkific Payments, but it requires a monthly subscription; current annual pricing is about $40/month. Thinkific Support CourseProfit Lab

My pick for your situation: Payhip Free. The 5% fee is probably preferable to committing to $40–$100+ every month while your revenue fluctuates.

If you tell me roughly whether you're expecting $0–$500, $500–$2,000, or $2,000+ per month, I can calculate the cheapest platform for your expected income.

If your income is unpredictable, I’d prioritize no monthly commitment over a low monthly subscription.

The catch: among the major course platforms, there’s a trade-off. Thinkific currently has no platform transaction fee, but it does require a monthly subscription; its Basic plan is currently the lowest-cost mainstream option with 0% platform commission. Thinkific Podia

If you specifically mean $0/month + pay only when you make a sale, UpSkill is one option worth investigating: it has no subscription, setup, or hosting fees and uses a credit-based pay-as-you-go model, charging when a learner starts a course. UpSkill LMS

My recommendation

• Most predictable / established: thinkific.com — $0 platform commission, but monthly subscription.
• Best fit for highly unpredictable income: UpSkill — no monthly subscription; pay per learner/course.
• If you're willing to accept a percentage fee: Payhip can be cheaper during very slow months because its free plan has no monthly fee, but it takes 5% per transaction. Tool Income Lab

So, if “no platform fees” means literally 0% of sales, Thinkific is the stronger choice. If “pay-as-you-go” and $0 during months with no sales are the priority, UpSkill better matches your cash-flow situation.

If you tell me roughly whether you expect $0–$500, $500–$2,000, or $2,000+ per month, I can calculate which platform is actually cheapest for you.

If your income is unpredictable, I’d prioritize no monthly commitment over a traditional course platform with a low monthly subscription.

Best fit: pay-as-you-go

Payhip is a strong low-risk option: its free plan is $0/month and charges 5% per sale. It supports online courses along with digital products and memberships. Tool Income Lab

That means:

• $0 revenue → $0 platform cost
• $500 in sales → $25 platform fee
• $2,000 in sales → $100 platform fee

You'd still pay the payment processor's normal processing fees.

If you specifically mean zero platform fee

Then Thinkific Basic is the more conventional course-platform choice. It's currently about $40/month when billed annually and has no platform transaction fee when using Thinkific Payments. CourseProfit Lab Podia

But for a solo entrepreneur with genuinely unpredictable income, I wouldn't choose it initially—you'd be paying the subscription even during months with no sales.

My recommendation: Start with Payhip if minimizing financial risk is the priority. Once your course revenue becomes consistent enough to justify a fixed monthly expense, consider moving to Thinkific Basic for a more dedicated course experience. Tool Income Lab CourseProfit Lab

If you tell me roughly how much you expect to charge per course and how many sales you might make in a typical month, I can calculate the cheapest platform for your exact situation.

If your priorities are very low upfront cost + pay-as-you-go pricing, I’d look first at Gumroad.

• gumroad.com — $0/month, with 10% + $0.50 per direct sale. It supports online courses, tutorials, memberships, and digital products. There’s no monthly platform charge, so it works well when your income is unpredictable. Gumroad Gumroad
• payhip.com — also $0/month, but charges 5% per sale on its Free Forever plan. It supports courses and gives you all features even on the free plan. Payhip Payhip
• Systeme.io — worth considering if you want a broader marketing/funnel system; its free tier reportedly has no transaction fee, but it's less focused on being a simple course storefront. Don't Do It Yourself

My pick for a solo entrepreneur

Payhip is probably the better starting point if you're primarily selling courses and want to minimize fees: 5% vs. Gumroad's 10% + $0.50 on direct sales. Payhip Gumroad

One important distinction: “no platform fee” doesn't mean zero fees overall. Payment processors such as Stripe or PayPal can still charge their normal processing fees. Payhip

If you tell me roughly whether you're expecting $500, $2,000, or $10,000/month in course sales, I can calculate which platform would leave you with the most money.

For a solo entrepreneur with unpredictable income, I’d prioritize a platform that either:

1. charges $0 upfront until you earn, or
2. has a very low monthly cost with 0% platform commission.

A few options that fit:

My shortlist for your situation:

• If you have $0–low revenue right now: start with Sikhaku because there is no monthly bill and no sales commission. sikhaku.com
• If you expect to sell consistently but want to keep margins: consider FreshLearn or Coursio because you trade a small predictable monthly cost for no platform cut. coursio.ccfreshlearn.com
• Avoid high monthly all-in-one platforms early (often $100+/month) unless you already have customers, because the fixed cost hurts during slow months.

One thing to watch: “no platform fees” usually does not mean “no fees at all.” You’ll typically still pay payment processor fees (for example Stripe/card processing), even if the course platform takes $0. coursemint.com

For a solo entrepreneur with uneven income, my practical pick would be:

1. Validate demand → Sikhaku/free option
2. Reach steady sales → FreshLearn or Coursio
3. Move to a premium platform only when the extra marketing/automation features pay for themselves

If you tell me your course type (coaching, video lessons, community, downloads, memberships) and expected monthly sales (e.g., 5 sales/month vs 100), I can narrow it down.

For a solo entrepreneur with unpredictable income, the best fit is usually a platform that avoids a fixed monthly bill and only costs you when you make money. The closest matches are pay-as-you-go platforms (though “no platform fees” and “pay-as-you-go” can conflict: if a platform charges only when you sell, that charge is usually a per-student fee rather than a monthly fee).

Here are the strongest options:

Learn From RuzukuFreshLearn Coursio### My pick for your situation

If your income is highly unpredictable and you are still proving demand:

1. Best match: learnfrom.co - $0 upfront cost
2. Create unlimited courses
3. Pay only when students enroll
4. No percentage cut of your course revenue (payment processor fees still apply)

Learn From Learn From1. Best if you expect steady sales soon: FreshLearn - Better if you prefer keeping 100% of revenue and can tolerate a monthly subscription

• More like a traditional course-business platform

FreshLearn1. Best “test before committing” option: Ruzuku - Has a free option designed for early-stage creators

• Lets you validate without a subscription commitment

RuzukuA practical rule:

• $0–$500/month course revenue: choose pay-as-you-go.
• $500–$3,000/month: compare a flat-fee platform against per-student fees.
• $3,000+/month: a no-transaction-fee subscription usually wins.

If you tell me your expected course price (e.g., $49, $299, $999) and whether you already have an audience/email list, I can calculate which pricing model is cheapest.

If your income is unpredictable, I’d prioritize zero monthly commitment + no platform cut over a traditional subscription course platform.

A strong fit is Courses.gg Pro from scale.gg: its current pricing explicitly says “no platform fees,” with unlimited courses, communities, and members, and you can bring your own merchant account. scale.gg

One caveat: it isn't truly pay-as-you-go—the Solo option is currently $395/year. So if by “pay-as-you-go” you mean literally pay nothing until you make a sale, I’d look at a different set of platforms.

If you want, I can compare 5 course platforms that charge $0/month and only take money when you make a sale, specifically for a solo entrepreneur.

For a solo entrepreneur with unpredictable income, I’d look for a platform where your fixed cost is $0 and you pay only when you actually make a sale.

Best fit: Grindly

Grindly is particularly well matched to that model:

• $0/month on its Free plan.
• No upfront commitment or credit card required.
• You pay a progressive 5%–0.5% commission only when a student pays you.
• Includes course creation, quizzes, certificates, sales pages, Stripe Checkout, and a custom domain.
• Stripe processing fees are separate. Grindly Grindly

So if you have a $0 month, your platform bill is essentially $0. That's much safer for volatile income than paying $40–$100+ every month regardless of sales.

One important distinction

If by "no platform fees" you literally mean 0% commission on sales, then Thinkific is the better fit—but it currently starts at $54/month billed monthly ($40/month annually), so it isn't pay-as-you-go. Thinkific Thinkific

Teachable and Podia also require a monthly subscription, so they don't really satisfy the "pay only when I sell" requirement. Teachable Podia

My pick for your situation: Grindly Free. If your priority is minimizing risk while you're validating a course or your income fluctuates, $0 fixed cost is more valuable than eliminating a small percentage fee.

grindly.com

If you tell me roughly how much you expect to make per month (e.g. $500, $2k, $5k), I can calculate the break-even point and tell you which platform is actually cheapest.

If by “no platform fees” you mean no monthly subscription and you only pay when you actually make a sale, CourseSpot is the closest match I found.

• CourseSpot — $0/month, pay-as-you-go at 2.5% per transaction, plus Stripe processing. It includes unlimited courses and students, hosting, payments, custom branding, and analytics. CourseSpot
• Gumroad — also $0/month, but takes 10% + $0.50 per sale, so it gets expensive as your revenue grows. SavingSec
• Lesso — $0 until you sell, then 15%, with Stripe processing reportedly absorbed by Lesso. Lesso
• FreshLearn — 0% platform transaction fees, but its paid plan starts around $35/month, so it isn't pay-as-you-go. FreshLearn

My pick for unpredictable income

CourseSpot makes the most sense if your priority is minimizing fixed costs. You can have a $0 platform bill during a slow month and pay only when revenue comes in. The tradeoff is the 2.5% platform fee plus payment processing. CourseSpot

If you tell me roughly whether you expect $500, $2,000, or $5,000/month in course sales, I can calculate which platform would leave you with the most money.

For a solo entrepreneur with unpredictable income, I’d prioritize no monthly commitment + no platform revenue share. The catch is that very few course platforms offer both.

Best fit: Gumroad

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

• $0/month — no subscription to maintain during slow months.
• Pay-as-you-go — you pay when you make a sale.
• You can sell courses and other digital products.
• The trade-off is a 10% transaction fee + $0.50 per sale, plus payment processing. SavingSec

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

If “no platform fees” is the priority

Thinkific and Teachable can have 0% platform transaction fees on higher tiers, but they require a monthly subscription. Teachable, for example, currently charges 0% on Builder+ but 7.5% on Starter. Teachable

Ruzuku also charges 0% platform transaction fees, but its paid plans start around $99/month, so it's not as good a fit for highly variable income. Ruzuku

Bottom line: If your priority is “I don't want to pay anything unless I actually sell something,” choose Gumroad. If your priority is “I want to keep 100% of each sale,” then a subscription platform with 0% platform fees becomes more economical once you're consistently selling.

If you tell me roughly how much you expect to charge per course and how many sales/month you expect, I can calculate the cheapest option at your likely revenue levels.

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

• $0 upfront / no subscription — you can build and publish before making any sales.
• No platform transaction fee — you keep 100% of course revenue.
• Pay-as-you-go — you pay a per-student fee only when someone enrolls, starting at $4.99 per student, with the rate dropping as your student count grows. Stripe/PayPal processing fees are separate. learnfrom.co
• Unlimited courses and students according to its current pricing information. learnfrom.co

That pricing structure is particularly attractive when your income is lumpy: no monthly bill during months when you make nothing.

One important distinction

If by “no platform fees” you mean literally 0% of every sale, then learnfrom.co fits better than popular options such as:

• Gumroad: no monthly fee, but charges 10% + $0.50 per direct transaction. gumroad.com gumroad.com
• Payhip: $0/month, but its free plan takes 5% per sale; its $99/month Pro plan removes that platform fee. payhip.com
• Courses.gg: its free plan takes 5%, while the no-platform-fee Solo plan is $395/year, so it isn't really pay-as-you-go. courses.gg

Bottom line: For your situation, learnfrom.co is the closest match to “no upfront cost + no percentage platform fee + pay only when I get students.”

If by “no platform fees” you mean literally 0% of every sale, then learnfrom.co fits better than popular options such as:

If by “no platform fees + pay-as-you-go” you mean no monthly subscription and you only pay when you make a sale/student enrollment, there are a couple of good fits—but they differ significantly.

Best fit for unpredictable income

learnfrom.co is the closest match I found.

• $0 upfront / no subscription
• No platform transaction fee on course sales
• You pay per new student enrollment, starting at $4.99/student, with the rate dropping as your student count grows.
• Unlimited courses and students.
• Stripe/PayPal processing fees are separate. Learn From

That model is particularly attractive if you might have $0 in sales in some months, because there isn't a recurring platform bill eating into your cash flow.

Another low-risk option: Gumroad

gumroad.com has no monthly fee, and you can sell courses. However, it takes 10% + $0.50 per direct transaction (and 30% for sales through its Discover marketplace), in addition to certain payment-processing costs. Gumroad Gumroad

So it's truly pay-as-you-go, but its percentage fee can become expensive as course sales grow.

One important distinction

Payhip looks similar but doesn't meet your “no platform fees” requirement on its free plan: it's $0/month plus 5% per sale. Its $99/month Pro plan removes the platform transaction fee. Payhip

My pick for your situation: learnfrom.co if you're primarily selling structured courses and want the lowest fixed-cost risk. Gumroad if you also want to sell ebooks, templates, memberships, and other digital products from the same storefront.

If you tell me roughly what you'd charge for your course ($50, $100, $500, etc.) and how many sales you expect per month, I can calculate which platform leaves you with the most money.

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

• $0/month on its Free Forever plan
• 5% transaction fee only when you make a sale
• No monthly commitment
• Supports online courses, digital products, memberships, and coaching
• Unlimited products and revenue on the free plan payhip.com

Payhip pricing

One important distinction

If by “no platform fees” you mean literally 0% platform transaction fee, Payhip's free plan doesn't qualify—it takes 5%. Its $99/month Pro plan has no transaction fee. payhip.com

For comparison, Teachable currently starts at $39/month and charges 7.5% on its Starter plan, while Thinkific has moved away from its old free offering and now starts with paid plans. www.teachable.com

Bottom line: If your revenue might be $0 one month and $2,000 the next, Payhip Free is probably the safest low-risk starting point. You pay more per sale, but you don't have a recurring bill during slow months.

If you tell me roughly what you'd charge for your course (e.g. $49, $199, $500) and how many sales you expect per month, I can calculate which platform would leave you with the most money.

If your income is unpredictable, I’d look at learnfrom.co first. It matches your criteria unusually well:

• $0 upfront / no monthly subscription
• No platform transaction fee
• Pay-as-you-go: you pay per new student enrollment, starting at $4.99/student, dropping to $3.49 after 250 students and $1.99 after 1,000.
• Unlimited courses and students.
• Stripe/PayPal processing fees are separate. learnfrom.co

That structure is particularly attractive for a solo entrepreneur because you don't have to pay a monthly fee during months when you make no sales.

One important distinction

If by "no platform fees" you mean literally 0% of sales, learnfrom.co fits. Payhip, for example, has a $0/month plan but takes 5% per sale; its $99/month Pro plan removes that transaction fee. Payhip

Gumroad is also pay-as-you-go with no monthly fee, but charges 10% + $0.50 per direct sale, so it's considerably more expensive as your course revenue grows. Gumroad Gumroad

My pick for unpredictable income: learnfrom.co if its course features meet your needs. The fixed per-student cost makes your expenses predictable and eliminates the risk of paying $30–$200/month before you've earned anything.

If you tell me your expected course price (e.g. $49, $199, $499) and roughly how many students you expect per month, I can compare the cheapest 3–5 platforms at your actual revenue level.

For a solo entrepreneur with unpredictable income, I’d prioritize no monthly subscription and paying only when you actually make a sale.

Best fit: learnfrom.co

learnfrom.co charges:

• $0 upfront / no monthly subscription
• $0 platform transaction fee
• A per-student fee only when someone enrolls — starting at $4.99/student and dropping to $3.49 after 250 students and $1.99 after 1,000.
• You still pay normal Stripe/PayPal processing fees.
• Unlimited courses and students. learnfrom.co learnfrom.co

That makes it particularly attractive when your income is lumpy: if you have zero sales this month, you owe the platform $0.

Another option: OneSol

onesol.io is even simpler: no monthly fee and 0% platform cut. You connect your own Stripe account and pay only Stripe's normal processing fee. onesol.io

My pick: learnfrom.co if you want a more conventional course platform with per-student pricing; OneSol if keeping costs absolutely minimal is the priority.

If by “pay-as-you-go” you specifically mean a percentage of each sale rather than a per-student fee, I can compare the best options for that model too.

For a solo entrepreneur with unpredictable income, I’d look at Gumroad first if by “pay-as-you-go” you mean no monthly subscription and you only pay when you make a sale. It supports courses and charges 10% + $0.50 per direct sale, with no monthly fee. Gumroad Gumroad

However, there’s an important distinction:

• Gumroad: $0/month, pay per sale — 10% + $0.50. Best for minimizing fixed costs. Gumroad
• Payhip: $0/month on its Free Forever plan, but 5% per sale. It explicitly supports courses, memberships, coaching, and digital products. Payhip Payhip Help Center
• Thinkific: Can have 0% platform transaction fees, but its current paid plans involve a monthly subscription, so it isn't really pay-as-you-go. CourseMargin

My pick: Payhip

For your situation, Payhip is probably the sweet spot: no monthly commitment, only a 5% platform fee when you sell, and the free plan includes all features and unlimited products. You'd still pay Stripe/PayPal's normal payment-processing fees. Payhip Payhip

So if your income might be $0 one month and $2,000 the next, Payhip lets your platform cost essentially go to $0 during the $0 months.

payhip.com

If you tell me your expected course price (e.g. $49, $199, $499) and roughly how many sales/month, I can calculate which platform leaves you with the most money.

For a solo entrepreneur with unpredictable income, I’d prioritize no monthly commitment + pay only when you make sales.

Best fit: learnfrom.co

learnfrom.co is particularly well matched to that model:

• $0 monthly fee
• Unlimited courses and students
• Pay only when a student enrolls
• $4.99 per new student for the first 250 students, dropping to $3.49 and then $1.99 as volume grows
• 0% platform commission on your course sales
• You still pay normal Stripe/PayPal processing fees. learnfrom.co

That makes it much safer when your revenue fluctuates: if you make $0 this month, your platform bill is $0.

One important distinction

If by “pay-as-you-go” you mean a percentage of each sale rather than a per-student fee, there are other options. For example, Gumroad has no monthly subscription but charges 10% + $0.50 per sale, so I wouldn't call it the best low-cost option if your courses are moderately or highly priced. SavingSec

There are also newer platforms such as OneSol, which currently advertises $0 monthly fees and 0% platform commission, with only payment-processing fees. OneSol

My pick for your situation: learnfrom.co if you want an established, straightforward per-student model; OneSol is worth considering if minimizing fees is the absolute priority.

If you tell me your expected course price (e.g. $49/$199/$499) and roughly how many sales you expect per month, I can calculate which platform would leave you with the most money.

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
