Expenra

Context

What it is

Most accounting tools assume one organization per account. Expenra gives each organization its own isolated workspace, transaction history, and access control. Users can belong to multiple orgs and switch between them without losing context.

The platform has live integrations across Stripe billing, Plaid banking sync, secure Redis-backed sessions, and a multi-model AI assistant that answers finance questions against your actual data.

AI

How the AI assistant works

The assistant supports multiple LLM providers. Tool-calling connects it to real accounting data through validated server-side routes, so responses reflect the user's actual financial context. Raw database access stays behind validated server logic. Responses stream back to the client.

Integrations

Stripe and Plaid

Both integrations include validated webhook handling. Events get verified before any business logic runs, which prevents spoofed or malformed webhook data from touching the platform. Stripe handles subscription lifecycle events. Plaid handles bank account connections and transaction sync. Both use structured input validation throughout.
