With Mollie, your customers can pay invoices directly online via iDEAL. A payment button appears in the invoice email and on the invoice page. The customer clicks, chooses their bank, and pays.
The effect is huge: companies that activate Mollie see their average payment time drop from 16 days to 1.2 days. That makes a real difference to your cash flow and to the work involved in chasing payment reminders.
What do you need?
A Mollie account (free to create)
Your Chamber of Commerce (KVK) number
Your business bank account
UBO identification - Mollie requires identification of the ultimate beneficial owner(s) (UBO). Make sure you have valid proof of identity to hand when creating your account
Step 1 - Creating a Mollie account
Go to mollie.com and click Sign up
Enter your company details (company name, KVK number, address)
Verify your bank account
Activate iDEAL as a payment method in your Mollie dashboard
Note: Only activate iDEAL. Credit card is technically possible, but the transaction fees are around 4%. That's far too expensive for most removal companies. iDEAL is by far the most used and cheapest option.
This takes about 10 minutes. Mollie checks your details, which can take up to one working day.
Step 2 - Connecting Mollie in Bas
Go to Settings > Way of working > Integrations
Find Mollie in the list
Click Connect
Log in with your Mollie account
Click Save
The integration is now active.
Step 3 - Activating test mode
Before going live, you'll want to make a test payment to check that everything works. Mollie has a test mode for this.
Click your account name in the Mollie section
Set the switch to Test
Test mode is now active
In test mode you can simulate payments without any real money being transferred.
Step 4 - Making a test payment
Create a test invoice in Bas
Send the invoice to your own email address
Open the invoice email and click the payment button
Go through the payment process (choose a bank, confirm)
Go back to Bas and check whether the invoice status has been updated to Paid
If the status updates correctly, the integration works.
Note: Getting an error message during the test payment? Then the integration hasn't been activated yet. Check whether your Mollie account is fully verified and whether iDEAL is enabled as a payment method in your Mollie dashboard.
Step 5 - Switching off test mode at go-live
Note: This is the most critical step with Mollie. At one of our customers, test mode was still switched on after go-live. The result: all customers paid nicely via iDEAL, but no money came in. Every payment was a test payment. This wasn't discovered until a week later.
At go-live:
Go to your Mollie settings in Bas
Click your account name
Set the switch from Test to Live
Check with a real invoice whether the payment actually arrives in your bank account
Note: This point is on the go-live checklist. This is the most critical step at your go-live. If you forget this, everything appears to work but no money comes in.
How the customer pays
Customer receives invoice by email - Clicks "Pay directly via iDEAL" - Chooses bank - Pays via iDEAL - Automatically: invoice status changes to "Paid" in Bas - Customer receives payment confirmation
Payment methods on site
Mollie is one of two ways your customer can pay on site. The customer chooses which method they use.
Method | How it works | Suitable for |
Manual | The foreman enters the payment method themselves, for example: cash, card or bank transfer | Flexible: all payment methods outside Mollie |
Mollie (QR code) | Customer scans the QR code and pays via iDEAL | Fastest option, no extra hardware needed |
Partial payment on site
The customer doesn't have to pay the full amount on site. A partial payment is possible: the customer pays part via the QR code, for example, and the remaining amount is automatically added to the invoice. Handy if the customer doesn't have the full amount with them, or if a subsequent recalculation is still to follow.
Cost of Mollie
No subscription costs
Transaction costs: EUR 0.25 per invoice (Bas costs) plus the standard Mollie transaction fees
Tips
Start with Mollie. The payment button in your invoices makes an immediate difference for your customers and improves your cash flow. Setting it up takes 10 minutes.
Test first, then go live. Use test mode to check that everything works before you go live.
About 40% of residential customers pay via the payment button. For commercial customers this percentage is lower - they usually pay through their own accounts department. The payment button is therefore especially valuable for your residential business.
Watch out for
Forgetting to switch off Mollie test mode is the most common mistake with integrations. Everything appears to work - customers pay, the status gets updated - but no money comes in. Always check at go-live that test mode is switched off.
