Add-on: Mollie payments
In Beta. Contact support@storeganise.com to request access.
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
Please note this section is for demonstration only. Currently, all Add-ons must be installed by a Storeganise team member. Contact us to install an Add-on.
If your Add-on has already been installed, you can skip to step #3.
- In the Management Portal, go to Main settings > Add-ons.
- Find Mollie Payments and click Enable.
- A task appears prompting you to connect with Mollie. Click the link.
- Sign in to your Mollie account and select your organisation profile.
- 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
In your Mollie Dashboard:
- Go to Organisation settings > Products > Payments.
- 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.
Important: Currently, the Add-on only supports Credit cards (listed as "Cards") and Direct Debit (listed as "iDEAL"). Make sure to complete all the necessary Mollie compliance requirements for these to be added to your account.
How customers add payment methods
- Credit card: Customers add their card via a secure Mollie checkout. Mollie verifies the card with a €0.01 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:
- Go to Customer > Billing in the Admin Portal.
- Select an unpaid invoice.
- 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.
Quick start (cheat sheet)
- Enable Mollie Add-on in Main settings > Add-ons.
- Connect your Mollie account via the task prompt.
- In Mollie Dashboard, activate Credit card and/or SEPA Direct Debit.
- Customers add payment methods via booking, move-in, or the Customer Portal.

Frequently asked questions
1. Why is my invoice marked as "Pending" after using SEPA Direct Debit?
SEPA Direct Debit payments are not processed instantly. When a customer pays using iDeal to set up a SEPA Direct Debit mandate, the invoice will be marked as "Pending" until the payment clears. This typically takes 2–3 business days.
2. Can a customer still complete their booking if the invoice is pending?
Yes, the unit will be reserved after the customer completes the booking and payment method setup. Once the pending payment clears, the unit status will automatically update to "Occupied" (if auto move-in is enabled).
3. What if a customer updates their payment method after an invoice is already generated?
Any future charges—including outstanding pending invoices—will use the updated payment method. Mollie always uses the most recent valid mandate when processing payments.
4. Will customers see the full IBAN or card number in Storeganise?
No. For security reasons, only the last 4 digits of the IBAN or card number are shown.
5. What does "Mollie (Credit card)" mean on an invoice?
This indicates the payment was processed using Mollie, and the method used was a credit card. You'll also see "Mollie (Direct debit)" for SEPA payments.
