Automate Billing & Invoicing: How One Firm Saved 8+ Hours Monthly

A consulting firm slashed late payments and manual work by automating recurring billing with QuickBooks and Zapier. The result: 8+ hours saved each month and a 25% improvement in on-time payments.


By linking QuickBooks to Zapier, the firm set up automatic invoice creation and payment reminders. This workflow automation eliminated tedious manual tasks and ensured clients paid on time—boosting efficiency and cash flow.


The Challenge


Manual invoicing was slowing the consulting firm down. Each month, their finance team spent hours generating invoices, emailing them to clients, and following up on late payments. This process led to delays, errors, and unpredictable cash flow. According to Intuit, 69% of small businesses cite late payments as a top cash flow issue (Intuit, 2023). The firm needed a scalable way to automate recurring billing and reminders without hiring more staff.


The Solution


Flow Genius helped the firm integrate QuickBooks with Zapier, creating a seamless workflow automation for recurring invoices. By leveraging AI integration and smart triggers, invoices were automatically generated and sent to clients on schedule. Automated reminders followed up with clients before and after due dates, reducing late payments and freeing up staff time.


Implementation Steps


1. Identified all clients on recurring billing and mapped their invoice schedules in QuickBooks. 2. Used Zapier to connect QuickBooks with the firm’s email platform, setting up triggers for invoice creation and delivery. 3. Built automated workflows to send payment reminders three days before and after due dates. 4. Tested the system with a small client group, then rolled it out to all recurring clients. 5. Monitored results and fine-tuned reminder timing for optimal response rates.


Results


The consulting firm saved over 8 hours per month previously spent on manual invoicing and follow-ups. On-time payments improved by 25%, and late invoices dropped by 40%. Cash flow became more predictable, and the finance team could focus on higher-value tasks. Research shows that automation can reduce invoice processing costs by up to 60% (McKinsey, 2024).
