How it works

Lay out the document

Define the header, line-item table and totals as a template with repeatable rows.

Send the line items

POST the customer, items and amounts as JSON — the engine handles pagination and layout.

Get a PDF back

Receive a print-ready PDF in seconds, cached and ready to attach, store or download.

Questions

Why not run Puppeteer myself for PDFs?

You can — until you're maintaining fonts, a browser farm, retries and a queue. MostlyRender is that pipeline as an API, with predictable latency and a cache.

Do multi-page documents work?

Yes — repeatable rows and page breaks are handled by the template, so long invoices and reports paginate cleanly.
