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's feed is a freelancer advice blog with no trace of the software
Invoice Ninja is open-source invoicing software, but this feed carries none of it. Every entry is a freelancer advice post — raising your rates, project management tips, what clients look for, what to ask for — published monthly and truncated to a WordPress excerpt. No version, release or feature appears anywhere in the capture, and the product's actual development happens somewhere this source does not reach.

◆ 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's feed is a freelancer advice blog with no trace of the software
◆ Current state
Invoice Ninja is open-source invoicing software, but this feed carries none of it. Every entry is a freelancer advice post — raising your rates, project management tips, what clients look for, what to ask for — published monthly and truncated to a WordPress excerpt. No version, release or feature appears anywhere in the capture, and the product's actual development happens somewhere this source does not reach.
◆ Where it's heading
The content strategy is consistent and unchanging: monthly posts aimed at solo freelancers deciding how to run their business, with the product implicit rather than mentioned. That tells you who Invoice Ninja is selling to and nothing about what it is building. Cadence has been steady at roughly one post a month for over a year.
◆ Prediction
Expect the monthly freelancer-advice cadence to continue unchanged. Anything about the software itself will have to come from its releases, which this feed does not carry.
