Introducing Flex Invoicing: Streamlined, Automated, and Built for You

The following article is offered for informational purposes only, and is not intended to provide, and should not be relied on, for legal or financial advice. Please consult your own legal or accounting advisors if you have questions on this topic.

Managing invoices shouldn’t slow your business down. That’s why we’re excited to announce our latest product: Flex Invoicing. Our new integrated invoicing platform comes at no additional cost to customers with an existing bank account through Flex. We designed this with you in mind so you can create, send, and track invoices and get paid faster all in the Flex platform you already use.

With Flex Invoicing, you can simplify your financial workflow, keep your operations organized, and save time for what really matters: growing your business. And because it’s fully integrated with the all-in-one Flex platform, it works seamlessly with your existing accounts, payments, and financial management tools.

Check out this demo video where our Flex engineers walk through exactly how Flex Invoicing works and highlights its benefits:

Invoicing Made Easy with Flex

Flex Invoicing breaks down the billing process into four simple steps:

Step 1: Create Invoices

Generate polished, customized invoices in seconds. Each invoice comes with a unique, shareable payment link so your customers can pay quickly.

Step 2: Send Invoices

Add your recipients and let the platform handle the rest. Customers receive automatic emails with all available payment options.

Step 3: Track Invoices

Monitor invoice statuses in real time—see what’s paid, outstanding, or overdue—through an intuitive dashboard designed for clarity and control.

Step 4: Get Paid

Customers can pay via ACH or wire through the secure payment link. And with upcoming updates, credit card payments will also be supported for ultimate flexibility.

Steps Action Benefit
Step 1 Create Generate polished, customized invoices in seconds with a unique, shareable payment link.
Step 2 Send Add recipients and let Flex handle delivery. Customers receive an automatic email with payment options.
Step 3 Get Paid Receive payments via ACH or wire with automatic invoice status updates. Credit card payments coming soon.
Step 4 Track Monitor paid, outstanding, and overdue invoices in one intuitive dashboard for full visibility.

Why Flex Invoicing Stands Out

Flex Invoicing isn’t just about sending invoices to your customers. It’s about making financial operations virtually effortless. Here’s a quick look at what makes it different:

Feature Benefit
Streamlined Invoicing Send invoices fast with accurate details, taxes applied automatically, and polished formatting.
Invoice Tracking Easily track paid, outstanding, and overdue invoices in one centralized dashboard.
All-in-One Platform Manage accounts payable and receivable without juggling multiple systems.
Automatic Payments Customers pay via ACH or wire, and invoice statuses update automatically.

Upcoming Features to Look Forward To

Flex is committed to continuously improving your invoicing experience. Coming soon*:

  • Automatic Account Reconciliation: AI-driven matching of transactions and invoices.
  • Credit Card Payments: Give your customers more ways to pay, faster.
  • Automatic Follow-Ups: Set payment reminders on autopilot.
  • Invoice Financing: Convert unpaid invoices into cash to maximize cash flow.

Seamless Integration Across Flex

One of the most powerful aspects of Flex Invoicing is how it fits into the larger Flex ecosystem. When you use invoicing alongside Flex’s other products, like bill pay, expense tracking, and the Flex credit card, you get a unified platform for all of your financial operations. That means less switching between tools and more time focusing on running your business
