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

How PaidSeal does it
