BookingPress Mollie Payment Gateway Addon

BookingPress Mollie Payment Gateway Addon connects Mollie to the BookingPress appointment booking plugin. Its purpose is narrow and practical: give customers a way to pay for an appointment during the booking process, rather than sending them through a separate payment workflow. The addon uses Mollie API keys and exposes its settings through BookingPress → Settings → Payments.

Payment inside bookings

The important distinction is that this is a payment gateway addon, not a booking system on its own. BookingPress remains the place where appointments and payment settings are managed, while Mollie supplies the payment processing layer. For a site already using BookingPress, that keeps the integration focused on one checkout path and puts the gateway configuration alongside the rest of the booking settings.

Live and test API credentials are supported. That gives an administrator a separate route for checking the payment setup before switching to real transactions. It is a useful operational split for appointment businesses, where a payment problem during booking affects both the customer and the scheduled service.

A wide method list

Mollie is presented here as more than a card processor. The addon covers a large group of European and international payment methods, including:

• Visa, Mastercard, Maestro and American Express
• SOFORT, iDEAL, Bancontact and bank transfers
• Belfius Pay Button, EPS, Giropay and KBC/CBC Payment Button
• SEPA Direct Debit and PayPal
• Klarna Pay Later and Klarna Slice It
• Paysafecard, Przelewy24 and gift card payments
• Apple Pay and other local or alternative payment methods

This range is the addon’s main practical strength. A business serving customers across different European markets has more room to offer familiar payment choices, while Apple Pay and card support cover customers who prefer a quicker digital or conventional card transaction. The list also includes deferred-payment options through Klarna, alongside bank and direct-debit methods.

Configuration in context

The API-key approach gives the setup a clear boundary: credentials are entered in BookingPress, and the gateway is selected as part of the booking plugin’s payment configuration. Test and live keys make the distinction between setup work and accepting real money explicit. For an administrator, the useful detail is less about a separate Mollie interface and more about having the integration available where BookingPress payment options are already controlled.

The supported methods also suit different appointment businesses. A local service might focus on cards, PayPal or Apple Pay, while a business serving customers in several European countries could present regional options such as iDEAL, Bancontact, EPS or Przelewy24. The addon therefore offers breadth without suggesting that every site needs to activate every method.

What to weigh

The first limitation is the dependency on BookingPress. This addon does not provide appointment scheduling independently, so it has little value without the BookingPress booking plugin and its payment settings. It is a targeted extension rather than a general Mollie gateway for other WordPress checkout systems.

The second trade-off is configuration choice. The payment-method list is extensive, but the supplied information does not explain how individual methods are enabled, displayed or managed inside the booking form. Administrators will need to make sensible choices instead of treating the full list as a single, ready-made checkout. The copy also does not specify details such as refunds, recurring payments or transaction-status handling, so those areas should not be assumed from the method list alone.

Who it suits

This addon fits BookingPress sites that need Mollie as their payment provider and want more than basic card acceptance. Its strongest case is an appointment business with customers who use different European or alternative payment methods, especially where iDEAL, Bancontact, bank transfer, Klarna, Apple Pay or local payment buttons matter.

It is less suitable as a standalone payment solution or as a general-purpose Mollie integration for another booking plugin. Within the BookingPress setup, though, the combination of API-key configuration, test and live credentials, and a broad collection of payment methods gives administrators a focused way to add online appointment payments.
