Paddle customer portal.

Impact
Problem
Paddle customers wanted to spend less time managing subscription requests and more time growing their businesses, making a customer portal the most requested feature in 2024.
Challenges
Add, remove and manage payment methods
Update invoices, crucial if addresses are missing for tax needs
Cancel subscriptions within
a few clicks
View payment history and pay past due transactions



Discovery and learnings
The PM and I started by speaking with a wide range of customers to better understand our target audience and form strong early hypotheses. We chose to prototype early and gather quick feedback, creating branded prototypes tailored to individual customers.
Large and enterprise sellers didn't have a need for our customer portal
Sellers wanted the portal to look and feel like their website and products
Ideal for small to medium sized sellers who couldn't build their own

Early iterations, concepts and ideas
Prototypes and testing
Continuous feedback
I iterated through multiple prototypes, often breaking down user journeys to test specific parts in isolation. Since the target audience was B2C, I leveraged user testing platforms to continuously recruit participants and gather valuable insights.
