SendOwl specializes in digital file protection with basic funnel tools, while Sellfy offers an all-in-one store with print on demand but no post-purchase upsells. Both platforms charge monthly fees and hold your recurring payments hostage if you leave.

The Recurring Income Handcuffs
You spent months, maybe years, building a base of paying customers. They trust you. They signed up for your membership or subscription because of your digital content. And now you want to switch platforms.
Here’s where it gets painful.
Both SendOwl and Sellfy keep your recurring payments tied to their systems. Leave either platform, and those customers you worked so hard to acquire? They don’t come with you. The recurring revenue stream you built stays behind.
Think about what that means for digital sellers. Every customer who subscribed through SendOwl or Sellfy is essentially rented, not owned. You did the marketing. You created the digital product. You handled the support emails. But the payment relationship belongs to the platform.
I’ve talked to digital creators who felt stuck for years because migrating meant asking every customer to re-subscribe somewhere else. Most won’t. You lose 60-80% of your recurring revenue in the transition.
This isn’t a minor inconvenience. It’s a fundamental problem with how these platforms are designed. Unlike SendOwl or Sellfy, some platforms let you keep what you’ve built.
How to Actually Own Your Revenue
So what should you look for when you’re looking to sell digital products online?
First: a platform for selling where recurring payments stay yours. If you decide to leave, your customers and their payment relationships come with you. No re-subscribing. No lost revenue.
Second, watch out for revenue caps. Both SendOwl and Sellfy limit how much you can earn on each paid plan. Hit the cap, and you’re forced to upgrade.
Third, look for transparent pricing without surprise hikes. SendOwl raised prices 3x to 10x in 2025, and hundreds of customers pushed back publicly. If you’re looking to start selling digital downloads, that kind of instability matters.
CartMango was built with these problems in mind.
- You keep your recurring payments if you ever leave.
- There are no revenue caps.
- And it’s completely free until 2027, with zero monthly fees and zero transaction fee.
- The founder responds personally, averaging 2 hours and 16 minutes response time. For solopreneurs and small teams, that kind of human support matters.

CartMango Is Not For Everyone
CartMango isn’t trying to be everything for everyone. It’s built for solo digital creators, coaches, and consultants who want to sell digital goods without platform drama or technical headaches.
The core promise: your recurring revenue belongs to you. If you ever want to leave, your customers come with you. No re-subscribing required.
You get full funnel support. Upsells, downsells, and order bumps all work together. SendOwl doesn’t offer downsells and makes you choose between order bumps or upsells. Sellfy doesn’t offer upsells at all.
There are no revenue caps. You can create and sell different types of digital products like ebooks, online courses, and PDF downloads without hitting limits.
What CartMango doesn’t have: a learning management system (on the roadmap) and affiliate management (coming soon). If those are critical right now, look elsewhere.
But if you want to sell your digital products, memberships, and subscriptions without your recurring income being held hostage, CartMango handles that well.
SendOwl: File Protection Focus with Funnel Limitations
SendOwl is one of the older platforms in this space, around since 2010. It built its reputation on protecting digital files from unauthorized sharing. If you compare SendOwl to newer platforms, the focus on digital products like ebooks and PDF files is clear.
What SendOwl offers
SendOwl offers features for selling digital downloads:
- Protected download links that expire
- PDF stamping to discourage piracy
- Drip content delivery for online courses
- Subscription and membership support with trial periods
- Direct connections to Mailchimp, Kit, ActiveCampaign for email marketing
- Shopping cart functionality for your existing website
- Built-in affiliate program management
SendOwl pricing structure
SendOwl uses revenue-based tiers with no free plan:
- $39/mo for up to $833/mo in revenue
- $87/mo for up to $3,000/mo in revenue
- $159/mo for up to $8,333/mo in revenue
Hit the revenue cap, and you must upgrade. Like SendOwl, most ecommerce platforms for selling digital products charge transaction fees or monthly fees.
The limitations
SendOwl only supports one upsell per product. No downsells exist. If you enable order bumps, upsells get disabled.
In 2025, SendOwl raised prices dramatically. Some users saw increases of 3x to 10x. Hundreds of customers complained publicly.

The recurring payment issue remains: leave SendOwl, lose your subscription customers.
Best for
Creators who prioritize file protection and don’t need post-purchase funnels. If you sell standalone digital files and want strong piracy protection, SendOwl delivers. Just know the funnel limitations.
This is the link for SendOwl.
Sellfy: All-in-One Store Without Post-Purchase Funnels
Sellfy positions itself as an all-in-one platform that allows you to sell digital and physical products from one storefront.
The ecommerce platform supports digital products, physical products, subscriptions, and print on demand merchandise. If you want an online store focused on digital products with some physical goods, Sellfy vs SendOwl often comes down to this all-in-one approach.
What Sellfy offers
Sellfy allows you to sell digital products with these built-in features:
- Built-in storefront with customization options and product page templates
- Print on demand integration (no inventory needed)
- Subscription support for recurring products
- Protected download links for digital goods
- Embedded cart for your existing website
- Direct payouts to your payment gateway
Sellfy pricing structure
Sellfy uses revenue-based pricing with no free plan:

- $79/mo for up to $4,166/mo in revenue (Business)
- $159/mo for up to $16,666/mo in revenue (Premium)
The caps are higher than SendOwl, which helps if you’re growing quickly. Sellfy is one of the more affordable options when you look at revenue limits.
The limitations
Sellfy has no upsells. No downsells. If post-purchase funnels matter to your business model, Sellfy won’t work.
Subscription trials and setup fees aren’t supported. Order bumps exist only on Business and Premium plans.
BNPL options are limited to PayPal Pay Later. The platform supports both digital and physical products but the built-in marketing features are limited compared to dedicated marketing tools.
Full migration is only on the Premium plan. And like SendOwl: leave the platform, lose your recurring customers.
Best for
Creators who want a simple all-in-one store with print on demand built in. If you’re selling digital downloads, merch, and subscriptions without needing funnels, Sellfy keeps things straightforward. The user interface is simple and you can start selling quickly.

What You’ll Actually Pay: A Side-by-Side Cost Breakdown
Here’s what each platform costs at different revenue levels. All calculations include Stripe/PayPal payment processing fees (2.9% + $0.30 per transaction) assuming a $50 average order value.
| Monthly Revenue | SendOwl Cost (per month) | Sellfy Cost (per month) | CartMango Cost (per month) | CartMango SAVINGS (per year) |
|---|---|---|---|---|
| $1,000 (20 orders) | $39 + $35 processing = $74 | $29 + $35 processing = $64 | $0 + $35 processing = $35 | $468 vs SendOwl, $348 vs Sellfy |
| $5,000 (100 orders) | $87 + $175 processing = $262 | $79 + $175 processing = $254 | $0 + $175 processing = $175 | $1,044 vs SendOwl, $948 vs Sellfy |
| $10,000 (200 orders) | $159 + $350 processing = $509 | $79 + $350 processing = $429 | $0 + $350 processing = $350 | $1,908 vs SendOwl, $948 vs Sellfy |
| $50,000 (1000 orders) | Revenue exceeds $8,333 cap | $159 + $1,750 processing = $1,909 | $0 + $1,750 processing = $1,750 | N/A vs SendOwl, $1,908 vs Sellfy |
At $50,000/month revenue, SendOwl’s highest tier caps out at $8,333 monthly revenue. You’d need custom pricing.
CartMango has no revenue caps and no platform fees until 2027. If you’re looking to sell and want to keep more of what you earn, the savings add up.
