Sending Invoices with iDEAL or Wero — Get Paid Faster as a Freelancer (2026)

Waiting for manual bank transfers is one of the most frustrating parts of freelancing. You send the invoice and then wait, with no certainty about timing.

A payment link on your invoice removes friction: your client clicks, chooses a bank, and pays in seconds. No manual IBAN entry, no searching for old invoices.

This article explains how iDEAL and Wero payment links work, how to set them up with Mollie and Declair, and how they help you get paid faster.

Why manual transfer delays payment

Without payment links, many freelancers are paid after 30-45 days. Not because clients refuse to pay, but because manual transfer creates friction.

Payment links reduce that friction:

No IBAN typing
No copy-pasting invoice references
Direct handoff to banking app
Instant confirmation for both sides

Freelancers using payment links are paid on average 11 days faster.

Two payment methods for Dutch freelancers

iDEAL — Dutch default

iDEAL is the most-used online payment method in the Netherlands and supported by nearly all major Dutch banks.

For freelancers with mostly Dutch clients, iDEAL is usually the best option: familiar, fast, and low-cost.

Wero — European alternative

Wero is a newer cross-border payment network launched by major European banks.

If you invoice clients outside the Netherlands, Wero can be a strong addition because clients in multiple EU countries can use a familiar local flow.

	iDEAL	Wero
Countries	Mainly Netherlands	Multiple EU countries
Best for	Dutch clients	International EU clients
Instant payment	Yes	Yes
Typical fee via provider	Low	Comparable

What does it cost?

Declair does not charge transaction fees.

You only pay your payment provider (Mollie), for example:

Payment method	Fee per transaction
iDEAL	EUR 0.29
Credit card	1.8% + EUR 0.25
Wero	Comparable to iDEAL

Mollie has no mandatory monthly subscription for basic usage.

Setup in 4 steps

Step 1 — Create a Mollie account

Go to mollie.com and register. Verify your company details.

Step 2 — Copy your API key

In Mollie, go to Developers → API keys and copy your live_ API key.

Step 3 — Connect Mollie in Declair

Open Settings → Payments in Declair, paste the key, and test the connection.

Step 4 — Send your first invoice with payment link

Once connected, each invoice can include:

A payment button in the invoice email
A link and QR code on the PDF invoice

What your client sees

When your client clicks the payment button, they open a secure hosted payment page with:

Amount due
Your company name/invoice context
Enabled payment options (iDEAL, Wero, card, etc.)

The page is mobile-friendly and supports direct app-based bank authorization.

Combine payment links with automatic reminders

Payment links are even more effective when reminders re-send them automatically.

Reminder	Timing	Tone
Friendly reminder	3 days before due date	Informative
First overdue reminder	7 days after due date	Neutral
Second overdue reminder	14 days after due date	More formal
Final reminder	30 days after due date	Formal/legal

Each reminder includes the payment link, so clients can pay instantly.

If payment still does not arrive, follow this guide: Unpaid Invoice — What Now?.

Add payment links to already-sent invoices

If you sent an invoice without payment link, you can still add one:

Option 1: Resend from Declair after Mollie connection
Option 2: Copy the payment link and send it by email or chat

Common mistakes

Keeping Mollie in test mode

Make sure you switch from test_ to live_ keys before going live.

Enabling only iDEAL for international clients

For non-Dutch clients, add Wero and/or card options.

Not testing the payment flow

Run at least one full test to verify status updates and notifications.

Summary

Adding iDEAL or Wero payment links is one of the fastest ways to reduce late payments. Setup takes minutes, transaction fees are low, and invoices become easier to pay.

For Dutch clients, iDEAL is typically the strongest default. For broader EU clients, combine iDEAL with Wero.
