Slipstack — Invoices & PDFs as an API
Invoices & PDFs as an API - JSON in, PDF out
Generate pixel-perfect invoices, receipts, and documents from JSON with a single API call. No headless browsers, no templates to maintain.
Hey Product Hunt! I built Slipstack because every time I needed invoice PDFs in an app, the answer was running headless Chrome somewhere (slow, heavy, flaky) or fighting a template engine for hours.
Slipstack is one endpoint: POST your line items as JSON, get back a clean, professional PDF in about 200ms. No Chromium, no templates to maintain. Tax, discounts, and totals are computed for you, and you can brand documents with your logo and colors.
There's a free tier (50 docs/month, no card needed), and if you just need one invoice right now there's a completely free generator that doesn't even ask for an account: slipstack.dev/tools/invoice-generator
Bonus for the AI crowd: it ships with a remote MCP server, so Claude, Cursor, or any MCP client can generate invoices as a native tool.
I'd love your feedback - especially on pricing and which document templates to add next!
