Mollie for Houzez
Mollie payments inside the Houzez real estate theme. No WooCommerce, no second checkout, no core files touched. The plugin uses the Houzez checkout you already have, through the theme’s own hooks, and runs beside Stripe and PayPal or entirely on its own.

What you can charge for
- Membership packages, one-time or recurring, set per package
- Single property submissions
- Featured and upgraded listings
- Standalone payment links, with a QR code and an invoice, for anything that happens away from the site
Subscriptions
Packages renew automatically through Mollie using SEPA Direct Debit. A SEPA pre-notification goes out before each charge. Members cancel their own subscription from the Houzez dashboard and keep access until the paid period ends. A failed payment triggers a grace window and automatic retries before access stops, and expiry reminders are sent for you.
Setup
The Quick Start Wizard handles it: install, paste your Test and Live API keys, run the connection test, choose your methods. Test mode and live mode are separate, so you switch when you are ready. A built-in guide covers Apple Pay and Google Pay. No code, no theme edits.

Licence and updates
One yearly licence covers every update and support while it is active, with a new version roughly every four to six weeks. If a renewal is missed, a 31-day grace period begins in which everything keeps working and a countdown appears in your admin. After that the settings lock, but your data and settings stay untouched and return the moment you renew.
