Bigcapital vs Concur: at a glance
What is Bigcapital?
Bigcapital is rebuilding its frontend in TypeScript while patching cross-tenant holes
Bigcapital ships roughly weekly, almost entirely from one maintainer. The August releases split between a sustained TypeScript migration of the web app — constants, hooks, guards, form pages, item and warehouse modules moved to typed camelCase — and a build-out of end-to-end test coverage for financial reports, bank rules, expenses and contacts CRUD. User-facing additions are modest and steady: bulk delete for item categories, row-height control, a redesigned item form, bulk account activation.
What is Concur?
SAP Concur leans into AI-assisted configuration and an overdue admin UX rebuild.
Concur is in a visible modernization push across two fronts: a refreshed admin experience for the platform and the first AI-assisted configuration features landing in Audit Rules. Travel-side work is steady — vendor swaps (Renfe to Trainline), automatic activations of new Concur Travel — alongside country-specific compliance plumbing for markets like Poland. The cadence reads like a deliberate Q1 platform refresh rather than a steady stream of point updates.

◆ Current state
Bigcapital ships roughly weekly, almost entirely from one maintainer. The August releases split between a sustained TypeScript migration of the web app — constants, hooks, guards, form pages, item and warehouse modules moved to typed camelCase — and a build-out of end-to-end test coverage for financial reports, bank rules, expenses and contacts CRUD. User-facing additions are modest and steady: bulk delete for item categories, row-height control, a redesigned item form, bulk account activation.
◆ Where it's heading
The security thread is the one worth watching. Across June and August the project fixed cross-tenant attachment access, cross-tenant access via an organization-id header, SQL injection in dynamic listing sort order, predictable S3 attachment keys, unverified Plaid webhook signatures and a TOCTOU race in financial commands — six advisories in the window, several with GHSA identifiers. That is a self-hosted accounting product being audited in earnest, and the responses have been prompt.
◆ Prediction
Expect the TypeScript migration and e2e suite to keep consuming most release volume for several more versions, with feature work staying incremental. The audit-log work flagged as enterprise in June suggests a paid tier is where larger features will surface.

SAP Concur leans into AI-assisted configuration and an overdue admin UX rebuild.
◆ Current state
Concur is in a visible modernization push across two fronts: a refreshed admin experience for the platform and the first AI-assisted configuration features landing in Audit Rules. Travel-side work is steady — vendor swaps (Renfe to Trainline), automatic activations of new Concur Travel — alongside country-specific compliance plumbing for markets like Poland. The cadence reads like a deliberate Q1 platform refresh rather than a steady stream of point updates.
◆ Where it's heading
The platform is being repositioned from a configuration-heavy expense tool toward one where AI handles the rule-writing for admins. Auto-upgrades and auto-activations of the new Travel experience suggest SAP wants the legacy install base off old code by year-end. The new Admin UX is the connective tissue — a single surface that lets the AI suggestions, audit rules, and travel migrations cohere instead of feeling bolted on.
◆ Prediction
Expect AI-assisted configuration to expand from Audit Rules into expense policy and approval workflows next, paired with more aggressive forced migrations of legacy Travel customers as the new admin experience rolls out broadly.
