Combinator (W23)Get paid without chasing customers
Reminder AI finds overdue invoices, drafts polite follow-ups, and shows finance what is paid, late, or blocked.
Why it breaks
Collections follow-up gets messy when every customer needs a different touch
The hard part is not sending a reminder. It is knowing who to contact, when to follow up, how firm to be, and whether the invoice is actually still unpaid.
Manual chasing creates inconsistent follow-up
Finance teams lose time checking invoice age, customer history, open threads, and who should send the next reminder.
Generic reminders can damage relationships
A high-value customer, a new buyer, and a repeat late payer should not receive the same message at the same point in the cycle.
Escalation often happens too late
When ownership is unclear, overdue invoices sit quietly until cash risk becomes urgent and the customer conversation gets harder.
Payment status gets split across systems
Teams jump between inboxes, spreadsheets, payment processors, accounting tools, and CRM notes to understand what is paid or blocked.
How Reminder AI fixes it
One workflow from overdue invoice to customer-safe follow-up
Each step is designed for teams that need reliable collections motion without making every reminder feel like a manual fire drill.
