Payroll platform's developer changelog has slowed from monthly in 2024 to three releases across all of 2025.
PayFit is a payroll and HR platform with deep France and UK coverage. The developer-facing changelog ran monthly through 2024 but slowed to three releases in 2025 — workingTimeModality and exemption fields on French contract endpoints (December), retroactive 24-month accountingV2 document generation (August), and absence status filtering (June). 2024 entries fill the rest of the recent window.
GOAT.tax completes multi-company portfolio management in its UI while adding state-by-state R&D credit coverage each sprint.
GOAT.tax is a vertical R&D tax credit platform shipping bi-weekly feature bundles aimed at tax professionals and their firm clients. The current cycle is completing a multi-month multi-company buildout: backend support landed in August, and the September release brings the unified Company Overview UI and a self-service company/study creation flow. In parallel, the team is methodically adding state-specific R&D credit logic — Colorado, Indiana, California, Pennsylvania — with each release extending geographic coverage.

The public developer changelog has clearly deprioritized. The 2025 entries are field additions and existing-endpoint improvements rather than new product surfaces. PayFit may be making fewer partner-facing changes, or simply moving partner communication off the public changelog.
Without more recent data the safe bet is continued slow cadence on the developer changelog with primarily incremental field additions. A return to monthly cadence would be the early signal that PayFit is reinvesting in the partner ecosystem.

The multi-company capability marks a category shift: GOAT.tax is no longer a single-entity R&D credit workflow tool but a practice management platform for firms handling multiple client entities. The state credit expansion is systematic — each sprint adds one or two states — suggesting a plan to reach full 50-state coverage over the next 12–18 months. UX work (full-screen tables, saved column views, icon-based controls) is maturing the interface for the high-data-volume workflows that characterize multi-company tax studies.
The next releases will likely expose more multi-company features — cross-company reporting, batch study operations, or consolidated portfolio views — to leverage the infrastructure now visible in the UI. State credit coverage will continue one to two states per sprint.
