404ops Payment Forms

Build a payment form, embed it, get paid. Your Stripe keys, your Stripe account, your money — we take no percentage of anything.

Free, with no transaction fee

• Unlimited forms and unlimited submissions.
• Every Stripe payment method your account supports — card, US bank account (ACH), Link and Cash App Pay.
• Stripe-hosted Checkout for every transaction. This plugin never renders a card field; card data never touches it or your server.
• Fixed amounts or "name your price", with a minimum and maximum you set.
• Built-in spam protection on the checkout endpoint — honeypot, minimum time-to-submit and a per-IP rate limit — with no third-party CAPTCHA and nothing to sign up for.
• File uploads — let payers attach a receipt, photo or PDF, with the file type checked rather than trusted.
• Everything the payer typed, kept on your own site, shown with the payment and included in exports.
• Email notifications to you and to the payer, an on-page confirmation with a reference they can quote, and Stripe Tax if you have it enabled.
• Overview, Payments history, and Revenue and Form-performance reports, each with CSV export and a test/live filter.
• A free AI form builder — describe the form in plain English using your own API key, or a local model.

What Pro adds

• Recurring subscriptions, with a subscriptions report.
• Coupons and discount codes, with a redemption report.
• Invoices.
• Abandoned-checkout recovery — see sessions that started and never completed.

On per-transaction fees

Some form plugins take a percentage of every payment on top of Stripe's own fee. At £1,000 a month that is around £360 a year; at £20,000 a month, roughly £7,200.

We take nothing. The Pro licence is a flat annual price whatever you process, and the free tier has no fee either.
