SolidInvoice vs Stigg: at a glance
What is SolidInvoice?
SolidInvoice 3.1 brings custom invoice templates and moves migrations off web requests.
SolidInvoice, the self-hosted invoicing app, shipped 3.1.0, 3.1.1 and 3.1.2 together on 29 October. 3.1.0 adds custom invoice templates and invitation expiry; 3.1.2 fixes the in-app upgrade path by running migrations at startup or as a Helm pre-upgrade job. It follows the 3.0 release in June that brought 2FA, OAuth and Meilisearch search.
What is Stigg?

Stigg closed October with its entitlements engine pointed at AI agents: an open-source Agent Governance SDK in beta, credit reservation and settlement, and Usage Governance generally available on all plans from November 1.

SolidInvoice
5.0FINANCE
SolidInvoice 3.1 brings custom invoice templates and moves migrations off web requests.
◆ Current state
SolidInvoice, the self-hosted invoicing app, shipped 3.1.0, 3.1.1 and 3.1.2 together on 29 October. 3.1.0 adds custom invoice templates and invitation expiry; 3.1.2 fixes the in-app upgrade path by running migrations at startup or as a Helm pre-upgrade job. It follows the 3.0 release in June that brought 2FA, OAuth and Meilisearch search.
◆ Where it's heading
After 3.0's identity and platform work, 3.1 turns to customization and operations, with Helm-based deployment now a supported path. Fixes are tagged with detailed commit-level notes, some co-authored with Claude.
◆ Prediction
Expect more 3.1.x fixes around upgrades and deployment, given two fix releases shipped alongside 3.1.0.
Stigg
7.5FINANCE
Stigg reprices itself with a free plan and monthly billing, days after Usage Governance GA.
◆ Current state
Stigg closed October with its entitlements engine pointed at AI agents: an open-source Agent Governance SDK in beta, credit reservation and settlement, and Usage Governance generally available on all plans from November 1. On November 3 it changed how it sells itself, making new pricing with a free plan and flexible monthly billing generally available to new customers.
◆ Where it's heading
The product is moving down-market while it moves into agent spend control. A free tier and monthly terms lower the barrier for the smaller AI teams the credit and governance features are built for.
◆ Prediction
The entries don't say what the free plan includes; the next releases will likely define its limits or make Usage Governance easier to set up without sales help.
