Your clients' developers can now produce defensible R&D evidence at the source. Keep the T661 in your firm — file confidently with a cryptographically-sealed chain of custody attached.
The Numbers
Canadian SR&ED consulting firms typically charge a contingency fee — a percentage of the credit they help you recover. The industry range is well established:
Source: Canadian Federation of Independent Business survey data, RDP Associates fee disclosures, and direct quotes from CTOs and finance leaders across 40+ Canadian R&D-heavy SaaS companies (2024–2026).
SR&ED is a tax form documenting a claim of research activity — and the specialist exists because the evidence isn't there to begin with. HammerAI doesn't file your claim. We capture R&D activity at the moment of work — git commits, JIRA tickets, source documents — and structure it into a defensible evidence package with model attribution, human approval gates, and a cryptographic seal. The evidence speaks for itself, and your accountant files the T661 with confidence.
The Flow
HammerAI doesn't practice tax law. It produces the evidence package that lets your existing accountant practice it with confidence.
HammerCLI scores every git commit. HammerRD scores every JIRA ticket. Silently, in the background — at the moment the work happens, not 12 months later.
Source documents go in. AI extracts findings, humans approve every claim, the entire chain — sources, decisions, model attribution — is cryptographically sealed. CRA-ready.
The evidence speaks for itself. The accountant doesn't need to reconstruct or reinterpret it — they file with the supporting chain attached. If CRA reviews, the seal proves what was claimed and when.
The specialist consultant exists today because most companies can't produce defensible R&D evidence on their own. When the evidence exists, the middleman is optional.
Install the free CLI in 60 seconds. Start capturing audit-defensible R&D evidence today — so your accountant can file with confidence, no specialist required.
