Sorpag

Context & problem

Sorpag, by Sortech, helps businesses generate invoices and automate payment collection, so they get paid on time without chasing every customer.

• Manual collection — Teams issued invoices and chased payments one by one.
• Late payments — Without reminders and clear status, receivables piled up.
• No overview — Managers could not see what was paid, pending or overdue.

Process & discovery

I designed the platform around the receivables cycle, from issuing an invoice to confirming the payment. I also worked full stack, building the web platform in Next.js, the mobile app in Flutter and the Node.js APIs for invoices and payments.

• Map — The full receivables cycle and its pain points with finance teams.
• Define — Automations for reminders, collection and reconciliation.
• Design — Invoice creation, payment status and a clear financial overview.
• Validate — Tests with finance users to simplify every step.

Results

Sorpag brought invoicing, collection and payment status into one automated flow.

• Automated — Payment Collection
• Invoice to Payment — in One Flow

Tools

Design and code in one flow: from UX/UI in Figma to the frontend and backend in production.

• Figma — UX/UI & Prototypes
• Next.js — Web Platform
• Flutter / Dart — Mobile App
• Node.js — Backend & APIs

Learnings

• Automate the boring parts — Reminders and reconciliation freed teams to focus on customers.
• Status at a glance — Clear payment states reduced doubts and follow-ups.
• Finance needs precision — Every number and date had to be unambiguous.
