Speed · Secure · Simple
Practical software for real businesses.
Lapistry is a small software studio building production-grade billing and business tools — full source, proven on real data, and ready to deploy or rebrand.
How we build
Software made to be owned, not rented.
Three principles run through everything we ship.
Speed
Ship in days, not quarters. Our tools are already built and battle-tested, so you skip the months of plumbing and go straight to value.
Secure
Money-grade integrity. Append-only ledgers, reversible posting, and books that always reconcile — the way accountants expect.
Simple
No bloat. Clean, self-hostable software you can actually run, read, and own — with documentation a human wrote.
Our products
Software you can run today.
Production-grade tools with full source — proven on real data, ready to deploy or embed.

About
A small studio with a high bar.
Lapistry is the studio of Jimmy A. Magbanua, a full-stack developer building practical software with Vue, Node, and PostgreSQL.
We focus on the unglamorous, high-trust corners of software — billing, ledgers, admin tools — where correctness matters and details can't be faked. Every product ships with full source code, clear documentation, and real-world testing.
Need something built or customized? We take on a small number of projects where we can do our best work.
