EVC Checkout embeds a Stripe card form directly on your pages, builds product cards from your Invoice Ninja catalog, recovers abandoned carts with AI, and emails digital license keys the moment a payment lands.
One WordPress plugin replaces your hosted-store subscription: catalog, payments, follow-ups and digital delivery.
Buy buttons open a branded checkout page on your domain with an embedded, secure card form. Customers never leave your site.
Products, prices, images and descriptions live in your Invoice Ninja account — shortcodes render them anywhere on WordPress.
A PAID Invoice Ninja invoice is created after money actually changes hands — no draft-invoice noise, clean books.
Billing details are captured the moment an email is typed. One reminder goes out an hour later with a link straight back.
Reminders are written per-cart by AI (Groq) in a professional, sales-oriented tone — with a safe fallback template if the API is down.
Stockpile digital license keys; a payment claims one, stamps it on the invoice, and emails it to the buyer automatically.
?r=CODE refs ride the buy flow straight into your payment metadata, so your own commission system always knows who sent the buyer.
A free-form CSS box and theme presets — the checkout matches your site, not ours.
Most sites are selling within the hour. The full walkthrough ships in the manual.
