PayUp — Late Payment Escalator

Overview

PayUp automates the awkward process of chasing late payments. Instead of manually drafting reminder emails or messages, businesses configure escalation rules — send a gentle reminder on day 3, a firmer notice on day 7, escalate to management on day 14. PayUp handles it automatically.

The Problem

Small businesses and freelancers lose significant time on payment follow-ups. The manual cycle of "draft email → check if paid → repeat" is inefficient and emotionally draining. PayUp turns it into a configurable, hands-off workflow.

Architecture

Supabase Edge Functions handle the scheduled reminder dispatch — they query overdue invoices, evaluate escalation rules, and trigger push notifications via Expo's notification service. The mobile app is the management interface; the logic runs server-side on a cron schedule.
