SaaS Startup Recovers $12K/Month with Invoice Automation
Automated failed-payment recovery and invoice generation eliminated the need to hire a full-time accounts receivable clerk.
The Problem
A B2B SaaS startup with 200+ paying customers was losing thousands monthly:
- ✗ Failed payments not retried (lost 5-10% of monthly revenue)
- ✗ Manual invoicing taking 20+ hours/month
- ✗ No system to track overdue accounts
- ✗ Manual accounting entries in QuickBooks
The Impact
-
$12K/month in lost revenue from failed payments
-
20+ hours/month on invoicing that could be development
