GOAT.tax vs InvoiceShelf: at a glance
What is GOAT.tax?
GOAT.tax adds multi-company support, partner white-labeling, and expands state R&D credit coverage
GOAT.tax is expanding across three dimensions: multi-company support (backend landed in August, company overview UI in September), partner white-label branding, and state R&D credit coverage (Pennsylvania added, Colorado, Florida, Minnesota, and California calculations updated). The UI is undergoing a systematic redesign — All Studies page, BC Allocation workspace, Expenses workspace — alongside feature additions, suggesting a coordinated platform maturation push.
What is InvoiceShelf?
InvoiceShelf 3.0 alphas let Claude, ChatGPT and Cursor draft and send invoices.
InvoiceShelf is pushing 3.0 through public alphas at a rate of several a week, each marked not for production. Alpha.5 added an MCP server so AI assistants can read, draft and send documents with the connecting user's permissions. Later alphas add role presets, user administration for the super admin, official modules on managed installs and a Docker image that runs on a read-only filesystem, alongside a steady stream of security fixes.

GOAT.tax adds multi-company support, partner white-labeling, and expands state R&D credit coverage
◆ Current state
GOAT.tax is expanding across three dimensions: multi-company support (backend landed in August, company overview UI in September), partner white-label branding, and state R&D credit coverage (Pennsylvania added, Colorado, Florida, Minnesota, and California calculations updated). The UI is undergoing a systematic redesign — All Studies page, BC Allocation workspace, Expenses workspace — alongside feature additions, suggesting a coordinated platform maturation push.
◆ Where it's heading
Multi-company and Controlled Group infrastructure (added in September as underlying data model) point toward larger enterprise engagements and complex corporate structures like affiliated groups filing consolidated R&D claims. The state-by-state credit expansion pattern suggests geographic coverage breadth is a deliberate priority. Once Controlled Group computation ships, GOAT.tax will cover the most complex R&D credit scenarios that currently require manual workarounds.
◆ Prediction
The Controlled Group data model added in September is infrastructure without a user-facing feature yet — expect Controlled Group computations (where multiple entities under common control aggregate R&D activities) to surface within 1–3 releases. That would unlock the large enterprise segment where R&D studies span affiliated entity groups.
InvoiceShelf
6.3FINANCE
InvoiceShelf 3.0 alphas let Claude, ChatGPT and Cursor draft and send invoices.
◆ Current state
InvoiceShelf is pushing 3.0 through public alphas at a rate of several a week, each marked not for production. Alpha.5 added an MCP server so AI assistants can read, draft and send documents with the connecting user's permissions. Later alphas add role presets, user administration for the super admin, official modules on managed installs and a Docker image that runs on a read-only filesystem, alongside a steady stream of security fixes.
◆ Where it's heading
3.0 is turning a single-company invoicing app into something a hosting provider can run for many customers: role presets across companies, provider-controlled module installs, a separate customer-portal host and a locked-down container. The security fixes (guessable document links, SSRF through mail settings, a setup token that acted as super-admin) show the multi-tenant hardening is still catching up with the feature work.
◆ Prediction
Expect more alphas that close security issues and fill out hosted-provider controls before a beta; the entries show no beta date.
