A mid-sized service company slashed late payments by 60% and saved 10+ hours weekly by automating invoice follow-ups using QuickBooks Online and Zapier. Faster payments led to improved cash flow and less manual admin.

By integrating QuickBooks Online with Zapier, the business set up automated reminders for overdue invoices. This workflow automation ensured customers received timely, personalized nudges—eliminating manual chasing and reducing outstanding receivables.

The Challenge

Manual invoice follow-ups drained staff time and delayed cash flow. The business struggled with late payments—over 40% of invoices were overdue each month, tying up working capital and increasing stress for the finance team. According to QuickBooks research, 64% of small businesses face late payments, with an average delay of 29 days (Intuit, 2023).

The Solution

Flow Genius recommended automating accounts receivable reminders by connecting QuickBooks Online to Zapier. This allowed the business to trigger custom email and SMS reminders as soon as invoices became overdue. The system also escalated persistent late payers to phone call reminders, all without manual intervention.

Implementation Steps

1. Audit current accounts receivable process to identify bottlenecks and common reasons for late payments. 2. Connect QuickBooks Online to Zapier, granting secure API access for invoice data. 3. Build Zapier workflows to trigger reminders: - 1st reminder: Email sent 3 days before due date. - 2nd reminder: SMS sent on due date if unpaid. - 3rd reminder: Escalation email and internal notification 5 days overdue. 4. Personalize reminder templates with customer names, invoice details, and payment links. 5. Test the automation end-to-end to ensure accurate triggers and messaging. 6. Train finance staff to monitor the system and handle exceptions. 7. Review and refine workflows monthly based on payment data and customer feedback.

Results

Within three months, the business reduced late payments by 60% and cut average payment time from 37 to 19 days. Cash flow improved, and the finance team saved over 10 hours per week previously spent on manual follow-ups. According to McKinsey (2024), businesses that automate receivables see a 30–50% reduction in overdue invoices—this case exceeded industry benchmarks.

A mini case study: Before automation, the company had $120,000 in overdue invoices each month. After implementing Flow Genius’ solution, that dropped to $48,000, freeing up $72,000 in working capital and reducing stress for both staff and customers.
