The Free Payment Plugin That Doesn’t Hold Back

Forms are native Gutenberg — no proprietary editor to learn. Start from a template or a blank block, then compose the form from drag-and-drop fields: name, email, phone, address, dropdowns, checkboxes, and free text. Pricing can be a fixed amount, a set of tiers, or an amount the customer chooses (the pattern behind donations and pay-what-you-want).

Embed the finished form with the SmartPay block, a shortcode, or as a popup overlay, and choose a stacked or split checkout layout. A per-form "require login" toggle covers members-only sales, and Cloudflare Turnstile, hCaptcha, or reCAPTCHA v3 keeps the bots out. Because it renders as normal blocks, it inherits your theme — no CSS surgery to make it match your site.

Most small sites pay for a separate invoicing service — or worse, wrestle invoices out of a spreadsheet. The free plugin includes the whole loop inside WordPress: create an invoice with your logo and business details, email it to the client, and track its status from draft to sent to paid (with overdue flagged for you).

Combined with the tax control system — percentage or fixed-amount rates applied per payment — the paperwork side of getting paid is handled the day you install the plugin.

Straight answers, since you'll compare anyway. WP Simple Pay's free version takes Stripe payments — but adds its own platform fee to each transaction until you upgrade. Paymattic's free tier also includes Stripe for one-time payments; if free Stripe specifically is your deciding factor, that's a genuine point in their column.

Where WP Smart Pay's free version pulls ahead is everything around the payment: built-in invoicing with status tracking (rare at any free tier), donation forms with custom amounts, tax control, three anti-spam options, and a reports dashboard — with no platform fee from us on any tier. And when you do upgrade, you're not just unlocking Stripe: you're adding Mollie, Paystack, Razorpay, subscriptions, and the AI agent toolkit nobody else has.

The free plugin is a complete tool, not a teaser — plenty of sites run it for years. Upgrades happen when the business changes shape: you want Stripe or a regional gateway, you're ready to sell subscriptions or take recurring donations, you need customers synced to your CRM, or you want your AI agent running the whole operation.

Everything carries over — forms, customers, invoices, settings. Upgrading is a license key, not a migration. And every plan includes a 14-day money-back guarantee, so the risk stays where it belongs: with us.
