Software that has to be right.
ProLedger Labs builds modular operating systems for businesses where the numbers carry weight — accounting, operations, healthcare and real estate. Every product is designed around data integrity, regulatory compliance and offline-first reliability, because the businesses running them cannot wait for a reconnect.
- Ledger-grade application architecture
- Modular .NET/VB systems on SQL Server or SQLite, built around double-entry integrity, inventory control and tax-compliant invoicing — so the books balance by construction rather than by correction.
- Domain-specific ERPs
- Systems shaped to one industry rather than configured into it, including Electron-based clinical management with patient registries, scheduling and localized billing.
- Offline-first and bilingual
- Desktop applications that work without reliable connectivity, with full English and right-to-left interfaces and locally bundled fonts rather than fetched ones.
- Licensing and distribution
- Machine-locked licensing, trial and activation flows, and single-file installer packaging, so software can be sold and deployed directly to clients.
Let's build something precise.
A new module, a localization pass, or a full system build — tell us about your operating environment and we'll scope it.
