How we score →Onshore is an AI platform that helps mid-market to enterprise companies identify, document, and claim R&D tax credits and other corporate tax incentives. Its AI agents analyze financial and operational data against the full tax code, then credentialed tax professionals verify every finding and deliver audit-ready documentation. The platform connects to existing accounting systems or accepts drag-and-drop document uploads, automatically surfacing eligible incentives across manufacturing, software, engineering, and other industries. Onshore has supported over 1,100 companies and identified over $800 million in incentives, with a typical 2-3 week turnaround. Key differentiators include results-based pricing (beyond traditional billable hours), AI speed combined with human oversight, and a recent $31M Series B rebranding from SPRX. Compared to DIY software-only solutions or traditional accounting firms, Onshore offers a middle path: automation for efficiency plus expert review for confidence.
Onshore hits a sweet spot for companies that have outgrown DIY spreadsheets but aren't ready for a full-time tax specialist. The AI handles the heavy lifting of document analysis against the tax code, while CPAs verify and file. That's a real time-saver: one customer reported a 10-day turnaround. What stands out is the results-based pricing — instead of hourly fees, you pay based on what's found. That aligns incentives. But there's a catch: the contact-only sales process means you can't just sign up online. If you're a small business with simple needs, this is overkill. You'd be better off with a traditional CPA or a cheaper software tool. Also, Onshore focuses on U.S. federal and state credits; international incentives aren't in scope. Another consideration: multi-year engagements are common; the company pitches ongoing value, which may not suit everyone. Compared to competitors like Xero or Gusto (which also offer tax credit services but with less depth), Onshore is more specialized. For CFOs of engineering or manufacturing firms who want defensible, audit-ready claims with minimal internal effort, Onshore delivers. For early-stage startups or sole proprietors, look elsewhere.
