What everyone else takes
Six ways to sell a book that’s already written, and what each costs at $500, $2,000 and $5,000 a month in sales. The rate beside each is what the platform actually keeps from a $9.99 book, fixed fees included. That’s not always the number they advertise.
Three of them collect your readers’ money and pass some of it back. One doesn’t handle the sale at all, which is why it needs a shop bolted to it. The last two are general stores that charge rent instead of a percentage and have never heard of an EPUB. Inkwharf never receives the money either: the charge is created on your own Stripe account, so no plan here takes a percentage and there’s no payout to wait for. Every page below also names the volume at which the other one is genuinely cheaper, because a comparison that never loses a round is an advert.
Inkwharf vs Leanpub
20% cutLeanpub is a writing toolchain with a bookstore attached. Inkwharf is a bookstore you own, with no toolchain. If you write in Markdown and want the book built for you, stay on Leanpub. If you already have an EPUB and an audience, there's no reason to hand over a fifth of every sale, plus a membership if you want the toolchain unthrottled.
Inkwharf vs BookFunnel
flat feeBookFunnel is delivery without a checkout, so selling direct with it means pairing it with a store and paying two bills. Inkwharf is both halves in one subscription. BookFunnel still wins outright on ARCs and group promos, which aren't selling at all.
Inkwharf vs Books.by
flat feeThe closest thing to this product that exists, and the honest split is by format: they print, we don't. Ebooks sit behind their $299 tier while their $99 one is print-only — but they take the payment and pay you out, which is the one thing here that's arranged differently on purpose.
Inkwharf vs Curios
flat feeThe same sentence as this product — sell direct, keep 100% — arranged the opposite way. Their fee is real and is charged to your reader at checkout, at 1–10% of the price plus the card fee; ours is charged to you, at $0 or $19 a month. Then the split widens: they're a marketplace with an app, an account and an NFT receipt, and this is a shop on your own domain handing over a file.
Inkwharf vs Payhip
5% cutPayhip sells anything digital and charges a percentage until you pay enough to stop it — 5% free, 2% at $29 a month, 0% at $99. Inkwharf sells ebooks only, takes nothing at any tier, and knows what an EPUB is. Below roughly $380 a month in sales their free plan is genuinely the cheaper deal, and we say so.
Inkwharf vs Gumroad
15% cutGumroad is the fastest way to put a file behind a payment link and the most expensive way to leave it there. The headline is 10%, but it's 10% + 50¢ — 15% of a $9.99 book — and 30% if the buyer arrived through their marketplace. The crossover against $19 a month arrives at about $127 in monthly sales.
Inkwharf vs Shopify
flat feeShopify is a store for physical goods that can be made to deliver a file. It bills $19 a month before the first sale, adds 2% to every sale taken through a provider that isn't Shopify Payments, and knows nothing about EPUB — no spec check, no chapter sample, no reader, no send-to-Kindle, no watermark. Inkwharf is free until you're selling $500 a month and is built around the file. The moment you sell anything physical, Shopify wins outright and this doesn't compete.
Inkwharf vs WooCommerce
flat feeWooCommerce is free software attached to a real bill: no licence fee and no cut, then hosting, updates, backups and your own hours. It sells downloadable products natively, so it will deliver an EPUB — as a file in a folder, with no spec check, no chapter sample, no reader, no send-to-Kindle and no watermark. Inkwharf is $0 to $19 a month with nothing to maintain. If you already run WordPress and like running it, Woo is cheaper and you should stay.
