Best Free WordPress Invoice Plugin (2026)
Updated 2026-08-09
What is a good free WordPress invoicing plugin?
A good WordPress invoice plugin should create professional invoices, add a pay button or client portal to your site without code, accept multiple payment methods, and keep card data off your server. PaidSeal is a free option: it drafts invoices with AI, connects in one click, adds Pay, Quote and Portal blocks, and accepts card, PayPal, Venmo, Cash App, Zelle, bank transfer and local methods like M-Pesa — paying out to your own account.

What to look for
- No-code setup — connect once, no API keys.
- Real payment methods — not just cards; ideally local methods too.
- Security — card data handled on a hosted PCI page, not your server.
- Your own payouts — money to your account, not held by the plugin.
- Blocks and shortcodes — works in the editor and page builders.
How PaidSeal does it
Install the free plugin, click Connect PaidSeal, and add a Pay Button, Request-a-Quote form or Client Portal to any page. Invoices can be drafted from a single sentence with AI, and customers pay by any method on a secure hosted page. You need a free PaidSeal account, created during Connect.
