Automating recurring invoice reminders with Stripe and Slack can cut overdue invoices by up to 49% (Xero, 2023) and save hours each month. This quick automation frees service business owners from manual follow-ups, letting you focus on growth.

By connecting Stripe’s payment data to Slack notifications, Flow Genius helps businesses automatically remind clients about unpaid invoices. This eliminates awkward email chains and ensures you never miss a payment deadline again.

The Challenge

Service businesses lose valuable time and revenue chasing late payments. According to QuickBooks (2024), 64% of small business owners report cash flow issues due to overdue invoices. Manual reminders are tedious, easy to forget, and often ignored by clients. The result: delayed cash flow, wasted admin hours, and unnecessary stress.

A local marketing agency, for example, spent nearly 10 hours monthly tracking and emailing late clients. Despite their efforts, 30% of invoices were still overdue each month.

The Solution

Workflow automation with Stripe and Slack transforms the payment reminder process. By integrating these tools, Flow Genius enables automatic Slack alerts for overdue invoices, prompting your team (or even your client) to act—no manual effort required.

This automation ensures reminders are sent consistently, reducing the risk of missed payments and freeing up your team’s time for billable work. It’s a simple, scalable fix for any service business using Stripe for billing.

Implementation Steps

1. Connect Stripe to a workflow automation tool (like Zapier or Flow Genius’s custom integration platform). 2. Set up a trigger for “invoice overdue” or “payment failed” events in Stripe. 3. Configure the workflow to send a customized Slack message to a designated channel or user when an invoice is overdue. 4. Optionally, add conditions for recurring reminders (e.g., every 3 days until paid). 5. Test the workflow with a sample invoice to ensure notifications are timely and accurate. 6. Train your team on responding to Slack reminders and following up with clients if needed.

Results

After implementing this automation, the marketing agency reduced overdue invoices from 30% to 12% within two months—a 60% improvement. They reclaimed over 8 hours per month previously spent on manual reminders. Industry research shows that automated reminders can accelerate payments by up to 21 days (Xero, 2023). Staff morale improved, and cash flow stabilized, allowing the agency to invest more in client acquisition and growth.
