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 GOAT.tax?
GOAT.tax adds Form 6765 Section G reporting for large R&D credit filers.
GOAT.tax is filling in what Form 6765 requires. The 10/15 release adds a Qualified Activity Type breakdown (direct research, supervision, support) for studies that meet the Section G thresholds, captures EIN and NAICS codes for the report, and extends bulk SME assignment to wage and expense workspaces. Earlier releases added multi-company support, partner white-labeling, a Controlled Group data model and broader state credit coverage.

◆ 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.
GOAT.tax
5.0FINANCE
GOAT.tax adds Form 6765 Section G reporting for large R&D credit filers.
◆ Current state
GOAT.tax is filling in what Form 6765 requires. The 10/15 release adds a Qualified Activity Type breakdown (direct research, supervision, support) for studies that meet the Section G thresholds, captures EIN and NAICS codes for the report, and extends bulk SME assignment to wage and expense workspaces. Earlier releases added multi-company support, partner white-labeling, a Controlled Group data model and broader state credit coverage.
◆ Where it's heading
The product is moving upmarket: Section G applies only to filers above $1.5M in QREs and $50M in gross receipts, and multi-company plus Controlled Group work targets complex corporate structures. A steady UI redesign of workspaces runs alongside, aimed at making large studies manageable.
◆ Prediction
Expect the Controlled Group model to surface as user-facing computations, and Section G output to flow into the generated 6765 report within the next few releases.
