Bigcapital vs Stigg: at a glance
What is Bigcapital?
Bigcapital ships multiple releases per week, adding SMS notifications, banking audit logs, and Plaid hardening.
Bigcapital is an open-source cloud accounting product shipping at a high cadence — multiple tagged releases per week across server, webapp, and SDK layers. The last two weeks show a focused push on banking features: Plaid sync hardening, audit logs for banking modules, auto-recognition of bank transactions via queue, and a landed cost feature flag. SMS notifications are being wired in behind a feature flag, alongside a broad internal refactor from snake_case to camelCase API responses.
What is Stigg?
Stigg adds credit reservation and settlement for AI operations days after its agent SDK.
Stigg can now reserve credits before an AI operation starts and settle the actual cost when it finishes. It follows the beta Agent Governance SDK, an open-source library built on Stigg's entitlements engine. Earlier October releases added an Airwallex billing backend, credit usage grouped by feature and a Stripe Projects listing.

Bigcapital
5.0FINANCE
Bigcapital ships multiple releases per week, adding SMS notifications, banking audit logs, and Plaid hardening.
◆ Current state
Bigcapital is an open-source cloud accounting product shipping at a high cadence — multiple tagged releases per week across server, webapp, and SDK layers. The last two weeks show a focused push on banking features: Plaid sync hardening, audit logs for banking modules, auto-recognition of bank transactions via queue, and a landed cost feature flag. SMS notifications are being wired in behind a feature flag, alongside a broad internal refactor from snake_case to camelCase API responses.
◆ Where it's heading
The product is deepening its banking and financial operations surface. Plaid integration is getting production-grade attention (concurrent-run guards, proper disconnect handling, audit trails), and landed cost accounting signals a move toward more complex inventory and purchasing workflows. The API SDK with typed OpenAPI coverage is being built in parallel, suggesting a platform push toward integrations and potentially a public API offering.
◆ Prediction
SMS notifications and the typed SDK will likely ship out of feature-flag status as the next named releases. Landed cost, once out of flag, will be the headline capability for users with inventory and import workflows.
Stigg
6.3FINANCE
Stigg adds credit reservation and settlement for AI operations days after its agent SDK.
◆ Current state
Stigg can now reserve credits before an AI operation starts and settle the actual cost when it finishes. It follows the beta Agent Governance SDK, an open-source library built on Stigg's entitlements engine. Earlier October releases added an Airwallex billing backend, credit usage grouped by feature and a Stripe Projects listing.
◆ Where it's heading
Credits have become Stigg's main pricing unit, and the product is adapting them to AI workloads whose cost isn't known up front. Reserve and settle, together with the governance SDK, turns the entitlements engine into a spending control for agents.
◆ Prediction
Expect the governance SDK to use reservations directly for agent limits, and more reporting on reserved versus settled usage.
