Your shop, on your site

Add a product and put a Buy button on any page. The checkout wears your design, and payment happens on Stripe’s own page, so no card number ever touches your server.

Tax and invoices, handled

Each sale gets the right VAT for the buyer’s country, with VAT numbers checked in VIES. Outside the EU, Stripe Tax works out sales tax and GST wherever you’re registered. A numbered PDF invoice goes out by email, and each quarter’s figures are ready for your accountant.

Courses, memberships, downloads

One-off prices and subscriptions, files to download, gated pages to read, licences for what runs elsewhere. A refund takes back what it gave, by itself.

Build it all before you pay

Without a licence it runs in test mode, with test orders and test invoices, so a client can see the whole flow on staging. Once a site is live, no licence check ever stops it selling.

What it needs

  • A Stripe account to take real money
  • Working email, for invoices
  • The hosting Lettern already runs on
