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.
InvoiceShelf
6.3FINANCE
InvoiceShelf 3.0 alphas add bills and suppliers, moving it from invoicing into payables.
◆ Current state
Five InvoiceShelf 3.0 alphas shipped in five days. alpha.11 added purchasing (suppliers, bills, supplier credits, payments and refunds) and patched two unauthenticated PHP remote code execution flaws in the Docker image. Later alphas added module API 1.4 with bundled dependencies, EN 16931 e-invoicing with ZUGFeRD / Factur-X hybrid PDFs, a notification bell with automatic payment reminders, and an iOS app headed for TestFlight.
◆ Where it's heading
3.0 is turning InvoiceShelf from an invoice generator into a small-business accounting app: payables next to receivables, EU-compliant e-invoices, a module ecosystem, and native mobile apps. The pace suggests the team is finishing features before a beta rather than stabilizing.
◆ Prediction
Expect more alphas filling in accounting pieces and modules built on API 1.4/1.5, with the iOS app appearing on TestFlight; the entries don't show a beta date.
