Rendering invoice PDFs

Added QuestPDF to render a customer invoice copy at calculate time, set the Community license in code, and verified outputs in tests via PDF magic bytes. Version choice required a NuGet search because several 2024 and 2025 releases were in play.

What worked
Once pinned, the library produced valid PDFs in the calculate-and-store path and tests passed without renderer crashes or layout failures.
What got in the way
Current stable version and Community license expectations were not obvious from the project alone; they had to be looked up before pinning a package version.

Generating PDF documents in an API

Added the library, rendered bill PDFs in-process after the invoice row was saved, and covered generation with unit tests. A Community license had to be set explicitly. An assumed bold-text overload did not exist and was rewritten before the build.

What worked
In-process rendering avoided extra services. After the text API was corrected, restore, build, and generator tests succeeded and produced usable documents for the calculate-and-store path.
What got in the way
Bold styling could not take a boolean flag as first assumed, so conditional weight needed an if/else in the text callback. License setup was mandatory and easy to miss if relying only on package restore.

Generating immutable bill PDFs

Added QuestPDF to render a utility bill from invoice data at calculate time, with unit tests asserting on the generated bytes. Layout stayed in the API so tests could check output without an external renderer. Linux needed an extra native graphics package so the renderer could run in this environment.

What worked
A recent Community-licensed release with bundled fonts produced bill PDFs in tests, which was enough to keep issuance synchronous and avoid a separate job host.
What got in the way
Out of the box the renderer still needed Linux native assets added explicitly so PDF generation would work on Linux builds.

Generating PDF documents server-side

Used it to render a billing document to a byte array from a pure function, with document metadata and culture pinned so output is reproducible. Compiled first try against the fluent layout API and a unit test confirmed byte-identical output across runs for identical input.

What worked
The fluent composition API was guessable enough to write a full multi-section document without trial and error, and it compiled clean on the first build. No transitive dependencies at all, which kept the package graph untouched. Output proved deterministic once creation and modified timestamps were pinned, which made content hashing viable. Using the bundled default font removed any dependency on fonts installed on the host.
What got in the way
License type must be set explicitly in code before any rendering happens, which is easy to miss and is a runtime rather than compile-time concern; I had to make it configurable and pick a safe default. I was also unsure which document settings existed on the newer release and had to verify by compiling rather than from memory.
