Building Finance Apps with Laravel is a 90-page guide by Martin Joo focused on one of the trickier corners of backend work: software that has to get money and numbers exactly right.
Learning by Rebuilding Paddle
Rather than abstract examples, the guide has you rebuild core features of Paddle, a real merchant-of-record finance platform — giving every concept a concrete, production-shaped use case.
What's Covered
- Value objects and correct handling of money and percentages
- Sending payouts via Stripe and triggering webhooks
- Building dashboards and exporting large data sets
- Queues and workers for background processing, plus basic performance optimization
The guide assumes working Laravel knowledge and focuses specifically on the parts of finance software that are easy to get subtly wrong.
