Single is a capable app for musicians and creators. The comparison that matters for most file sellers is the fee model: Single takes a cut of every digital sale on top of its monthly plan, while Fulfile is flat with no per-sale fee and counts download limits per file. Every Single number below was verified July 8, 2026. Disclosure: this page is written by Fulfile’s founder.
The 30-second answer
Pick Single if you are a musician or creator whose product is streaming music, video, livestreams, or physical-plus-digital bundles. Pick Fulfile if you sell downloadable files and want a flat bill with no per-sale cut, per-file download limits, license keys, and watermarking. The more you sell, the more Single’s 15% per-sale fee adds up, and the more a flat plan saves you.
Single’s Shopify listing says “Usage Fees apply” and points to single.xyz for details. There, the fee is 15% on every digital sale, with a $0.15 floor and a $1.50 cap per transaction (verified July 2026). Because of the cap, any product priced around $10 or more effectively costs a flat $1.50 in fees every time it sells, on top of your monthly plan. Sell a $12 ebook 500 times in a month and that is $750 in per-sale fees before your subscription. On Fulfile the same 500 sales cost exactly your flat plan price: nothing per sale, on any tier.

Beyond price, the setting that saves you support tickets is how download limits are counted. Most apps cap downloads at the order level: one shared budget across every file in the purchase. Sell a 10-file bundle with a 3-download cap and an honest buyer can lock themselves out of most of what they paid for. Fulfile counts the limit per FILE, so each file has its own budget. Buyers also help themselves: expired links renew on the download page, and anyone who loses the email can re-send every purchase from fulfile.app/recover.
Honesty matters more than winning every row. Single is purpose-built for musicians and creators: if you sell streaming music and video, run livestreams or access passes, or bundle vinyl and CDs with digital, Single does things Fulfile does not, and its per-sale fee is capped so it stays predictable at higher price points. If your product is files a customer downloads and keeps, a flat plan with no per-sale cut and per-file limits is the better economics.

Does Single charge a fee per sale?
Yes. On top of the monthly plan, Single charges 15% on every digital sale, with a $0.15 minimum and a $1.50 cap per transaction, per single.xyz (July 2026). For any product priced about $10 or more, that is a flat $1.50 every time it sells. Fulfile charges nothing per sale.
Is Fulfile cheaper than Single?
It depends on volume, and that is the point. Single's plans run $0 to $119 per month plus 15% per digital sale. Fulfile is a flat $0, $19, or $39 per month with no per-sale cut, so the more you sell, the wider the gap grows in your favor.
Does Fulfile do music and video like Single?
Not the same way. Single is built for musicians and creators, with video hosting, livestreams, and physical bundles. Fulfile focuses on delivering downloadable files with per-file limits, license keys, and PDF watermarking. If music streaming and livestreams are your product, Single fits that; if you sell files buyers download, Fulfile fits that.
What are per-file download limits?
Each file in an order gets its own download budget, so a buyer of a multi-file pack can never lock themselves out of files they paid for by re-downloading one. Per-file budgets are what Fulfile is built around.
How hard is it to switch?
About 15 minutes: install Fulfile free, link your Shopify products, bulk-upload your files (up to 10 GB each), set limits and expiry, and send yourself a test delivery. New paid orders deliver through Fulfile immediately.
Keep 100% of every sale.
Flat pricing, no per-sale cut, per-file limits, license keys, and a real free plan. Nothing skimmed off the top.
