Finland insurance:
E-invoice registration research
The goal was to increase e-invoice activations in Finland before customers make their first payment. Wanted to understand why customers in Finland prefer to pay with paper invoices over e-invoices.
Despite prompts in users’ online banks, only 28% of insurance customers activated e-invoices, far from the 70% goal. Paper invoicing was driving operational costs.

"All pictures are from the live website today, and all data, numbers, and personal details shown in the case study are fictional and for demonstration purposes only due to confidentiality."

"Sending paper invoices is quite costly, and we don’t need these expenses when e-invoicing is a much more affordable option."
Interviews
Set up an interview with insurance customer support to get more insight into how e-invoice activation works. I gathered insights from their perspective based on their interactions with customers through phone and email.
🏦How to activate e-invocie

"E-invoices would be better if I got a message in my bank when they arrive. Otherwise, I don’t notice them."
💵
Manual payments feel safer
45% preferred paper/email for control.
“I want to approve my payments manually.”
⭕
Penalties are normalized
21% would switch if paper invoicing costs extra.
“If the paper invoice starts costing more, I might switch.”
🔎
E-invoice prompts are missed
54% didn’t see the prompt in their bank.
“I didn’t even know it was suggested until I checked weeks later.”
Next steps
I planned a workshop with stakeholders, developers, designers, and data. Outcomes were that, based on my research, we wrote tickets and gave the tickets an ICE scoring together.
After the tickets were added to the board, the hackathon group was created. Although I didn’t attend the hackathon, my research informed the direction of a cross-functional workshop across product, marketing, and support.
My insights directly informed a cross-functional hackathon, which led to a 12% drop in paper invoice usage (47% → 34%) within one month, reducing costs and improving user experience.
Result & Buisness impact
User research revealed exactly why customers weren’t activating digital invoices. Solving those pain points created customer value (clearer steps, fewer hassles) while driving business value (lower paper costs, higher digital adoption).
🎯Results (after 1 month):
-
Paper invoice usage decreased, reducing operational costs and environmental impact.
-
Multiple UX improvements were implemented based directly on user research insights, including:
-
New, clearer site layout and updated information architecture
-
Introduction of a penalty fee for paper invoices
-
Multi-channel reminders (email, SMS, push)
-
Visual, bank-specific activation guides
-
Stronger email CTAs and clearer success-state confirmations
-
Refreshed eco-friendly messaging to reinforce the value of switching
