From the blog
Manual invoicing is the tax you pay for getting paid — and one copy-paste away from billing the wrong client the wrong amount. Build the invoice template once, connect it to where your billing data already lives, and every invoice generates itself. The three setup paths (manual, spreadsheet, API/bulk), the variable map that works, a worked JSON example, and 3 real setups.
Rolling your own PDF generation means maintaining a headless browser, fighting page-break CSS, and rebuilding a templating layer your non-developers can't touch. A document generation API replaces all of it with one HTTP call. Auth, the exact request/response shape, cURL and Node examples, error handling, and why the full REST API ships on every paid plan.
Most business contracts are 95% identical — only the names, dates, and figures change. Yet teams still copy the last contract and pray the find-and-replace caught everything. Lock the legal boilerplate, expose only the variable fields, and generate clean contracts every time. How it works, where AI fits, the e-signature handoff, and the 5 contracts to automate first.
