Zimpler - User Portal

Users needed a single place to see paid, due, and overdue invoices, make payments, review history, and manage account-level details from links often opened on mobile.

• Designed a responsive portal with a mobile-first mindset.
• Clarified invoice list states, payment actions, transaction history, and account surfaces.
• Used status hierarchy and layout patterns to make financial information easier to scan.

The portal connected the payment experience after checkout, helping users resolve invoices directly instead of relying on external bank transfers.
