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.

Uses a simplified 6% illustration after the entered activity allocation and 65% contractor treatment. Actual qualification, domestic-research treatment, base amounts, elections, and credit limits require professional review. Owner draws and hypothetical salary are excluded.

Who QuarryFi is for

A good fit starts with real business spend.

An S-corporation owner-employee can be a fit when the company actually pays supported W-2 wages. Entity labels alone do not establish eligibility. Owner draws, unpaid work, hypothetical salary, and side-project activity do not create a wage basis.

  • A business organized and principally operating in the 50 states or DC
  • Software work that addresses technical uncertainty through experimentation
  • Actual W-2 wages, paid US research contractors, or other current R&E costs
  • A plan to review estimates and draft support with a qualified tax professional

How it works

From development metadata to reviewable support

  1. Connect your tools

    Link GitHub and tracking plugins. QuarryFi reads activity metadata, never source code or proprietary file contents.

  2. Review suggested classifications

    Activity blocks are compared with the IRS four-part-test framework and routed to a review state; software does not decide qualification.

  3. Prepare a support package

    See estimates, actual compensation context, Build Rate, evidence references, and draft Form 6765 inputs in one workflow.

R&E Expense Test Mode

Review cost context next to development evidence.

Actual wages, paid research contractors, cloud infrastructure, and development tools can raise different federal R&E and research-credit questions. QuarryFi keeps the cost record connected to the period and work evidence you choose to review.

Test Mode suggests categories and candidate links. It does not determine tax treatment, capitalization, deduction timing, or credit eligibility. Your tax professional reviews those decisions.

Build Rate

See Build Rate in context.

Build Rate compares lines changed with development hours classified for review. It is an internal directional metric, not a tax-qualification test or a universal measure of engineering quality.

Review the trend alongside project mix, codebase changes, staffing, and evidence coverage. Use the context to ask better questions rather than treating one number as a performance score.

A better professional handoff starts before year end.

Year-end reconstruction can make it harder to connect a business component, technical uncertainty, alternatives, people, and actual costs. Important context may live across repositories, payroll records, invoices, and individual memory.

QuarryFi keeps authorized development metadata, evidence references, review decisions, and cost context in one workspace so the company can prepare a clearer starting point.

Development systems contain useful metadata, but a commit or tracker heartbeat does not prove qualification by itself. The customer still identifies the business component and verifies what the evidence means.

QuarryFi helps organize that record against the federal activity framework, flags gaps, and prepares estimates and drafts for professional review. The taxpayer and advisor decide the filing position.

Your development work and actual business costs may contain facts worth reviewing for federal R&D support. Useful evidence may already exist in the workflow. QuarryFi helps organize it into a record you and your tax professional can verify.
