R&D tax credit software for engineering teams

Your engineering work is already financial evidence.

QuarryFi turns development activity into R&D credit estimates, R&E support, and Build Rate metrics your CPA can review.

R&E cost-base support

Your R&D costs need a clean support file.

The same work that generates R&D tax credits also produces R&E cost-base evidence. Wages, cloud infrastructure, tools, and contractors may support your CPA's review. Most businesses track none of it cleanly.

QuarryFi tracks both from the same data and models the credit-versus-deduction trade-off as a planning estimate for your CPA.

Build Rate

Most teams don't know their Build Rate. They should.

Build Rate is how much your team actually produces per hour of documented R&D work. It only becomes measurable once you know which hours qualify. Once you have the number, the question becomes obvious: is it going up or down?

Track it quarter over quarter. Use it to make the case for R&D investment. It's a number most leadership teams have never seen, and once they do, they want it every quarter.

Traditional R&D studies weren't designed for modern software teams.

Traditional R&D credit firms charge $10,000–$30,000 and reconstruct your year after it's over. Interviews with engineers. Spreadsheets built from memory. Narratives written by consultants who weren't in the room when the work happened.

They also only cover the tax credit. The R&E support file, the productivity data, the audit readiness score: none of that is part of the engagement.

The evidence already exists in your workflow. Every commit is timestamped. Every session is logged. Every technical decision leaves a trace.

QuarryFi connects that evidence to IRS language automatically. No interviews. No reconstruction. Contemporaneous records, a clearer R&E support picture, and a productivity metric that makes the investment visible.

Your R&D work may qualify for federal tax credits, R&E cost-base support, and a productivity metric that proves the output. The evidence already exists in your workflow. QuarryFi extracts it automatically. The value is already there.
