\section{Why LaTeX}

Why LaTeX for invoices?

Word processors and spreadsheets produce different output on every machine. LaTeX compiles to an identical PDF everywhere — perfect for billing documents that must be archived and reproduced exactly.

Pixel-perfect typesettingQuality

LaTeX's typesetting engine produces mathematically precise layouts — your invoice looks identical on every printer and screen.

Programmatic generationAutomation

Automate thousands of invoices from your database. Template once, generate forever.

Version-controlled templatesDevOps

Store invoice templates in Git alongside your code. Track every change, roll back any revision.

PDF/A archivingCompliance

Produce PDF/A-compliant archives that satisfy legal record-keeping requirements for years.

\begin{longtable}

Full invoice template

A complete single-page invoice with a branded header, bill-to block, itemised longtable with subtotal, tax, and total rows, plus bank payment details. Compiles with pdfLaTeX.

\includegraphics{company-logo}

Logo placement

Add your company logo above the invoice header using \includegraphics. LaTeX accepts PNG, PDF, and EPS formats. Place the image file in the same directory as your .tex file, or provide an absolute path. Vector formats (PDF, EPS) produce the sharpest results at any print resolution.

\newcommand{subtotal}

Totals calculation

LaTeX does not compute arithmetic at compile time out of the box. The recommended pattern for invoices is to define totals as \newcommand macros — calculated once in your data pipeline or template engine — and reference them throughout the document. This keeps the source clean and makes programmatic generation trivial. For dynamic arithmetic in LaTeX itself, the pgfmath or spreadtab packages can compute sums directly, though they add compilation complexity.

\newcommand pattern for invoice totals
% Define totals as commands for easy reuse
\newcommand{\subtotal}{458.00}
\newcommand{\taxrate}{0.085}
\newcommand{\taxamount}{38.93}
\newcommand{\totaldue}{496.93}

% Use in the table

& & Tax (8.5\%)       & \$\taxamount   \\[2pt]

Compile this invoice in the browser

The full invoice template is pre-loaded and ready to compile. Edit the line items, swap the client name, and download a pixel-perfect PDF — no TeX Live installation required.

\input{api-data}

Automation with the API

The FormaTeX API lets you generate invoice PDFs programmatically — pass your LaTeX template with interpolated data and receive a compiled PDF in the response. Scale from one invoice to millions without any infrastructure.

Manual workflow
  • Export from Word or Google Docs each time
  • Manual number formatting per invoice
  • Inconsistent fonts across operating systems
  • No audit trail — overwrite previous versions
  • Breaks at scale — copy-paste errors accumulate
FormaTeX API
  • Template + data → compiled PDF in one HTTP request
  • Consistent branding across every invoice, every time
  • Identical output on every platform and printer
  • Every compilation logged — full audit trail
  • Scales to millions of invoices with zero extra infrastructure
