Auto-generate PDF invoices.
Invoicing software is a strange market: the tools are either free and ugly, or polished and $15–30 a month for what amounts to a form, some arithmetic, and a print stylesheet. If you send a handful of invoices a month, you're renting a calculator. This blueprint flips the economics, you describe the invoice tool you want, and twenty minutes later you own one. No seat license, no branding watermark, no export paywall.
A working invoice generator with the parts that actually matter: itemized line items with quantities and rates, tax and discount handling, auto-calculated totals that react as you type, and a print-ready layout that saves cleanly to PDF. The money math is handled in integer cents, the classic floating-point rounding bugs are designed out, not patched later.
You watch it happen in the task workspace: the agent scaffolds the project, writes the calculation logic, starts the dev server, and verifies the page renders before handing you the live preview. The code lands in your repository on a branch, with a pull request prepared.
The first version is a starting point you can steer with plain follow-up messages:
Each follow-up wakes the same repository, and the agent continues on its own code.
Do I need to know how to code? No. You describe what you want; the agent writes, verifies, and ships the code to your repository. The pull request is there if you ever want to look.
Where does my invoice data live? In your app, in your repository, under your GitHub account. Nothing is shared with anyone else's service.
Can it email invoices? Ask for it, with an email service connected (like Resend), the agent can wire up sending. Without one, the print-to-PDF flow works out of the box.
