Mollie for Accounting Software | Mollie Documentation

Connect your Mollie Business Account to an accounting software through Bizcuit to automatically sync your payment data and simplify bookkeeping.

We support all major bookkeeping software in the Netherlands, including Exact Online, Twinfield, Yuki, Moneybird, SnelStart, Minox and more.

What you need to do in advance

Create a Mollie Business Account.
Ensure that you have an active account in your accounting software with the necessary rights to establish connections with third parties.
Have a bank account for your Mollie payments added and set up in your accounting software.
Bizcuit connects to Mollie through OAuth. This means that you have to be able to log in to both your Mollie account and your accounting software before starting the connect procedure. If you are already logged in to an account, OAuth will automatically connect to that account.

Troubleshooting common issues

Missing transaction history

If you’re not seeing transactions in your bookkeeping software, follow these steps to check your connection and settings:

Verify your connection In your Mollie Web App, go to Settings → Accounting, then click Manage. Make sure your accounting software is connected and that all bank accounts you coupled are listed and linked. Confirm that your bank account is also linked to the correct administration in your accounting software.
Complete any unfinished setup steps If any steps of the steps is incomplete, finish the setup and review all connection settings to ensure everything is properly configured.
Check your bank account setup Make sure the bank account of your choice is added and fully configured in your accounting software. Verify that it belongs to the correct administration.
If you’re using email-based connections Check your spam folder to ensure that files sent to your accounting system haven’t been filtered out.

If everything looks correct but the transactions are still not listed as expected, please contact us at [email protected].

Missing a particular transaction

If a specific transaction hasn’t appeared in your accounting software, it may be due to its current status. Transactions are only sent to your accounting software once they’ve been booked by the bank and can no longer be changed. You might have to wait for it to be processed first before appearing in the transaction list.

Error connecting to the Accounting Software

If you don’t have the necessary permissions to set up third-party connections with your accounting software, you may encounter an error during the connection process.

Your bookkeeper or another authorized person in your company should have the necessary permissions to establish the connection. You can ask them to grant you with the correct permissions or invite them (by email) to complete it on your behalf:

Go back to the screen where you selected your accounting software and select it again.
In the Connect accounting system step, choose No, my bookkeeper helps me.
Create a connection request for your bookkeeper: they will receive an email inviting them to connect the accounting software. They do not need their own Mollie account to complete this step.

Once the connection is successfully established, you’ll receive a confirmation email.

📘
Choose No, my bookkeeper helps me even if you’re completing the setup together or on the same device. Using a connection request ensures that your bookkeeper can manage connections securely and conveniently both for you and other clients. Important: don’t open the connection request link on the same device and browser from which you sent it. Doing so may mix up your steps and credentials, causing connection issues.

Accounting Software not on the list

To deliver transactions to accounting systems that don’t yet support a direct integration, you can select the option Boekhoudpakket algemeen. This option allows you to schedule regular exports of your bank transactions, which can be sent to your accountant’s email or saved in a secure Dropbox folder in your preferred format. Most accounting systems support the CAMT format for bank transaction exports. Systems that don’t support CAMT typically work with the MT940 format.
If you plan to analyze transactions or process them in Excel, choose the CSV format.
