Add-on: Mollie payments

The Mollie Payments Add-on lets you connect your Mollie account to Storeganise so you can accept credit card and SEPA Direct Debit payments directly from customers. Payments automatically link to invoices, and customers can manage their payment methods in the Customer Portal.

Prerequisites

• A Mollie account with business verification completed
• Storeganise invoicing currency set to EUR (Mollie Add-on only supports EUR)
• Storeganise team has installed the Add-on for your business (contact support if it’s not yet enabled)

How to connect your Mollie account

Note: The demo below is interactive.

1. In the Management Portal, go to Main settings > Add-ons.
2. Find Mollie Payments and click Enable.
3. A task appears prompting you to connect with Mollie. Click the link.
4. Sign in to your Mollie account and select your organisation profile.
5. Click Connect to complete the authorisation.

✅ Once connected, Storeganise will automatically detect your invoice currency. You don’t need to manually configure the currency code.

Configuring payment methods

Note: The demo below is interactive.

In your Mollie Dashboard:

1. Go to Organisation settings > Products > Payments.
2. Select the payment methods you want to enable.

⚠️ Currently, the Add-on supports:

• Credit cards (listed as “Cards”)
• SEPA Direct Debit (requires iDEAL to create a mandate)

Make sure you complete all Mollie compliance checks so these options become active.

How customers add payment methods

• Credit card: Customers add their card via a secure Mollie checkout. Mollie verifies the card with a €0.00 test transaction (usually refunded immediately).
• SEPA Direct Debit: Customers complete a one-time €0.01 iDEAL transaction to authorise their bank account. Mollie then creates a SEPA mandate so future invoices can be charged automatically.

Customers can:

• Add payment methods during online booking or move-in
• Manage or update them anytime under Customer Portal > Billing > Payment method

Charging invoices

You can charge invoices manually or automatically.

To charge manually:

1. Go to Customer > Billing in the Admin Portal.
2. Select an unpaid invoice.
3. If the customer has a valid payment method, click Charge.

• Credit card payments are processed instantly.
• SEPA Direct Debit payments take 2–3 business days to clear. During this time, invoices show as Pending.

To charge automatically:

• Enable Automatic invoicing in Storeganise. Payments will run automatically using the customer’s stored mandate.

Understanding payment statuses

• Paid – Payment was successful
• Pending – Payment is being processed (SEPA only, 2–3 days)
• Failed – Payment was declined or could not be completed

Statuses update automatically once Mollie confirms the result.

Troubleshooting

• Invoices stuck in Pending: This is normal for SEPA payments. They clear within 2–3 days.
• Currency mismatch errors: Ensure your Storeganise invoicing currency is set to EUR when using the Mollie (EUR) Add-on.
• Wrong site linked: Mollie Add-ons work at the site level. Customers must add payment methods separately for each site.
• Failed payments: Ask the customer to update their payment method in the Customer Portal.
