What is GOAT.tax?

State credit math keeps deepening while the study tables get easier to work in.

GOAT.tax runs R&D tax credit studies end to end, from wage and expense collection through business component allocation to a filed deliverable. This release tightens three state rules at once — Colorado now requires three years in the same Enterprise Zone, Indiana Research Activities fields get defaults so deliverables are never generated incomplete, and Minnesota picks up startup treatment that derives the applicable historical years and Fixed Base Percentage method dynamically. On the workspace side, R&D allocation percentages become directly editable in BC Allocation for single- and multi-state records, and the All Studies page and BC Allocation table are rebuilt on the newer design.

What is Invoice Ninja?

Invoice Ninja's release train is almost entirely payment-gateway repair work.

Six patch releases in under two weeks, and the substance is concentrated in the payment path: Square SCA handling for customer-present and customer-absent flows, token storage for offline charges, PayPal and ACH fixes, gateway fee refactoring, a checkout.com subdomain parameter. Alongside that sit platform chores — bulk actions extended to all entities, queued webhooks, N+1 query fixes, a Scout search driver.

GOAT.tax vs Invoice Ninja: editorial side-by-side

G
GOAT.tax
FINANCE
5.0

State credit math keeps deepening while the study tables get easier to work in.

◆ Current state

GOAT.tax runs R&D tax credit studies end to end, from wage and expense collection through business component allocation to a filed deliverable. This release tightens three state rules at once — Colorado now requires three years in the same Enterprise Zone, Indiana Research Activities fields get defaults so deliverables are never generated incomplete, and Minnesota picks up startup treatment that derives the applicable historical years and Fixed Base Percentage method dynamically. On the workspace side, R&D allocation percentages become directly editable in BC Allocation for single- and multi-state records, and the All Studies page and BC Allocation table are rebuilt on the newer design.

◆ Where it's heading

The state coverage thread has shifted from adding jurisdictions to encoding their harder eligibility and computation rules — Enterprise Zone tenure, startup Fixed Base Percentage methodology, and visible reasons when a state credit is ruled ineligible. That last one, plus the new Fixed Base Percentage details view and override, points at the same goal from a different angle: making the calculation auditable by the person running the study rather than trusting it. Fee handling entered the product this window too, with an optional not-to-exceed percentage and cap threaded through the fee structure, credit and deliverable pages.

◆ Prediction

Fee logic just appeared across three pages at once, so the next step is likely the rest of the billing path — applying the not-to-exceed cap to invoicing or partner-facing fee reporting. The notes give no schedule.

I5.0

Invoice Ninja's release train is almost entirely payment-gateway repair work.

◆ Current state

Six patch releases in under two weeks, and the substance is concentrated in the payment path: Square SCA handling for customer-present and customer-absent flows, token storage for offline charges, PayPal and ACH fixes, gateway fee refactoring, a checkout.com subdomain parameter. Alongside that sit platform chores — bulk actions extended to all entities, queued webhooks, N+1 query fixes, a Scout search driver.

◆ Where it's heading

Nothing here changes what the product does; it changes whether the product's most consequential path works. The concentration on Square, PayPal, ACH, and checkout.com across consecutive releases suggests gateway integrations are where the bug reports are, which is what happens when a self-hosted billing tool has to satisfy every processor its users chose. The infrastructure fixes — queued webhooks, query counts, bulk actions — are the shape of scaling work on installs that have grown.

◆ Prediction

Given the pace and the consistent gateway focus, the next few patches are likely to continue on payment drivers rather than introduce a feature. Whether a minor release is being staged behind them is not visible in these notes.
