Freelance Shield: Stop Losing Money

Hey everyone! I’m currently building Freelance Shield, a tool designed to help freelancers catch billing errors, missing payment terms, and legal risks in invoices before they ever hit "send."

As a fellow freelancer, I kept getting burned by my own mistakes—forgetting a net-30 term here, leaving a loophole there—and I got tired of losing money because of it.

I'm currently in the "bug-fixing" and polish phase, and I’d love to get some eyes on it from the community. If you’ve ever felt the pain of an invoice coming back with a dispute, I’d love to hear how you handle it.

Does anyone have a specific "invoice horror story" or a checklist you use to ensure your invoices are airtight? I’m looking to bake that wisdom directly into the tool.

Thanks in advance!
