For non-fiction authors

Sell the book your readers already came for

A newsletter, a talk, a decade of work in one field — and then a book that has to be bought from a retailer who keeps the reader's email and thirty percent of the price. If the audience is yours, the checkout should be too.

My readers are not technical. Will they manage it?

There is nothing to manage. They type an email address, pay, and land on a download page — no account, no password, no app. That page has the EPUB, a reader that opens in the browser, and one button that sends the book to a Kindle. If they lose the email a year later, they put the same address into the recovery page and get a fresh link without contacting you.

What you get

The buyer's email address is yours

Every sale gives you the reader, not just the revenue. That is the whole difference between a list you own and an audience you rent from a retailer.

One shop for the whole catalogue

Your name, your bio, your accent colour, and every title in one place — so the link in the back of one book sells the next three.

Sell wide at the same time

Nothing here is exclusive. Keep the book on Amazon, Kobo and Apple, and sell the same file from your own shop the same afternoon at 0%.

Bundles of your own making

Price each title as you like and put them all in one shop. A reader arriving from a podcast sees the catalogue, not one product page.

Tax collected at checkout

You are the merchant of record, which puts the VAT obligation on you — the honest half of keeping the money. Switch Stripe Tax on in shop settings and card checkouts collect the right rate for the buyer's country, prices tax-inclusive as the EU and UK require.

Updates reach people who already bought

A second edition replaces the file on every past buyer's permanent link. No re-purchase, no migration, no announcement email that half the list misses.

Bring the file you already have

Bring an EPUB from Vellum, Atticus, Sigil, pandoc, Reedsy or your designer. Every upload is validated against the EPUB spec before it can go on sale, and the listing writes itself from the file's own metadata and cover.

Not quite you?
