What is Lago?
Lago is layering AI agents and enterprise gates onto an already-deep usage-based billing engine.
Lago is an open-source usage-based billing platform that has matured well past metering and into the full operational stack — entitlements, wallets, credit notes, e-invoicing, and analytics. Recent quarters have added an AI agent and MCP server for natural-language billing operations, ML-backed revenue forecasts, and the enterprise scaffolding (custom roles, security logs, audit-tracked communications) that procurement teams ask for. The wallet subsystem in particular is becoming a product of its own, with multiple wallets per customer, transaction limits, alerts, and full traceability of credit flows.
What is SolidInvoice?
SolidInvoice 3.1.3 patches payment settling and clears 12 Symfony advisories.
SolidInvoice, the self-hosted invoicing app, is in a patch cycle on 3.1. The 29 October trio brought custom invoice templates, invitation expiry and a fixed upgrade path with migrations at startup or as a Helm pre-upgrade job. 3.1.3 follows with fixes: invoices paid through the API or MCP are only marked paid once the payment settles, the revenue chart counts each month once, and a Symfony bump clears 12 security advisories.

Lago is layering AI agents and enterprise gates onto an already-deep usage-based billing engine.
◆ Current state
Lago is an open-source usage-based billing platform that has matured well past metering and into the full operational stack — entitlements, wallets, credit notes, e-invoicing, and analytics. Recent quarters have added an AI agent and MCP server for natural-language billing operations, ML-backed revenue forecasts, and the enterprise scaffolding (custom roles, security logs, audit-tracked communications) that procurement teams ask for. The wallet subsystem in particular is becoming a product of its own, with multiple wallets per customer, transaction limits, alerts, and full traceability of credit flows.
◆ Where it's heading
Lago is positioning itself as the billing backbone for AI-native and credit-economy products — pricing units, prepaid wallet primitives, and an MCP server are not generic SaaS billing features. In parallel it's pulling forward enterprise governance: roles, security logs, e-invoicing, granular API endpoints. The combination reads as a deliberate move upmarket, with the AI-billing angle as the wedge for new logos and the governance work as the ceiling-raiser for existing ones.
◆ Prediction
Expect more agentic surface (additional AI agent personas beyond the Billing Assistant, or MCP server hardening with action-confirmation flows), and continued e-invoicing jurisdiction coverage following the France template — Italy, Belgium, or another Peppol-aligned market would be the natural next stop.
SolidInvoice
5.0FINANCE
SolidInvoice 3.1.3 patches payment settling and clears 12 Symfony advisories.
◆ Current state
SolidInvoice, the self-hosted invoicing app, is in a patch cycle on 3.1. The 29 October trio brought custom invoice templates, invitation expiry and a fixed upgrade path with migrations at startup or as a Helm pre-upgrade job. 3.1.3 follows with fixes: invoices paid through the API or MCP are only marked paid once the payment settles, the revenue chart counts each month once, and a Symfony bump clears 12 security advisories.
◆ Where it's heading
After the large 3.0 release in June, work has moved to hardening: upgrade paths, packaging (Snap, static PHP builds) and correctness in payments and reporting. The mention of MCP payments shows AI-agent access is already wired into billing, though the entries don't detail it.
◆ Prediction
Expect more 3.1.x patches on packaging and payment edge cases; the entries don't signal what 3.2 will contain.
