GOAT.tax vs Invoice Ninja: at a glance
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.
What is Invoice Ninja?
Invoice Ninja patches Square SCA, improves ACH handling, and extends bulk actions across all entities
Invoice Ninja is in active maintenance mode across its v5.13.x branch: payment gateway reliability (Square, PayPal, ACH) is getting sustained attention, with Strong Customer Authentication edge cases and token storage for offline payments being addressed. Bulk actions now span all entity types, and webhooks have moved back to queues with improved logging — signs of a maturing multi-tenant deployment model.

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.
Invoice Ninja
5.0FINANCE
Invoice Ninja patches Square SCA, improves ACH handling, and extends bulk actions across all entities
◆ Current state
Invoice Ninja is in active maintenance mode across its v5.13.x branch: payment gateway reliability (Square, PayPal, ACH) is getting sustained attention, with Strong Customer Authentication edge cases and token storage for offline payments being addressed. Bulk actions now span all entity types, and webhooks have moved back to queues with improved logging — signs of a maturing multi-tenant deployment model.
◆ Where it's heading
The product is solidifying its payment gateway layer rather than adding new gateway categories. The addition of inline images for PDF generation, JSON design previews, and configurable document visibility suggest steady UX refinement in the invoicing and document workflow. No architectural pivots visible — this is a product in reliable incremental improvement mode.
◆ Prediction
The current trajectory points toward continued payment reliability work, particularly around SCA compliance, as European payment regulations tighten. Bulk action expansion may extend to custom entity types in future releases.
