The Problem

Freelancers and agencies send invoices and then manually check their bank account to see if they got paid. Overdue invoices slip through the cracks. The average SMB has $84K in outstanding receivables.

The Solution

A payment tracking layer on top of your invoicing tool. Connect Stripe, PayPal, or your bank. See which invoices are paid, pending, or overdue. Auto-send payment reminders. Track your real-time cash position.
