Overview
GreenBar builds local-first tools. Clearing (and the rest of the suite) runs entirely on the customer's own computer. GreenBar operates no cloud for these tools and stores none of the customer's financial data. GreenBar AP Pay, our payables tool, is still in development and will run on the customer's machine the same way.
Clearing — local-first architecture
- Runs locally on Windows, macOS, and Linux. No account or sign-in to a GreenBar server. When a license key is saved, Clearing checks that key with greenbarsystems.com and checks for an update; both calls send the key only, never financial data.
- GreenBar operates no cloud for Clearing and stores none of the customer's financial data.
- Learning from user corrections stays on the local machine, per client — never pooled into a shared model.
- Installers are code-signed as Greenbar Systems LLC; auto-updates are signed and verified before being applied.
- Clearing works from files the customer imports. It does not connect to the customer's bank out of the box, and live two-way QuickBooks Online and Xero sync is not shipped. Optional team sync on Pro and Firm is off by default and runs only between the customer and a server the customer hosts.
AP Pay — in development
GreenBar AP Pay is being built and has not shipped; there is no release date to share. It will run on the customer's own machine, as Clearing does. Its security details will be published when it ships. We are not documenting controls that are still changing.
